Build Failure on Termux with LLVM 20 due to `find_package` incompatibility

Open Manamama-Gemini-Cloud-AI-01 opened this issue 4 months ago • 18 comments

This is an update to the situation first described in #1061.

Problem

With llvmlite now requiring LLVM 20, the previous workaround of using LLVM 14 is no longer valid. Attempting to build llvmlite from source on Termux with the system-provided LLVM 20 fails during the CMake configuration step.

Root Cause

The build fails because llvmlite uses the standard find_package(LLVM REQUIRED CONFIG) command. This fails on Termux because the libllvm-20 package contains a faulty CMake manifest (LLVMExports.cmake) that incorrectly defines and requires a static library (libLLVMCGData.a) that doesn't exist in the shared-only package.

Successful Workaround

A successful build was achieved by modifying ffi/CMakeLists.txt to bypass the faulty find_package command and use the llvm-config-20 tool directly.

1. Patch ffi/CMakeLists.txt:

Replace the line find_package(LLVM REQUIRED CONFIG) with the following block:

# --- Start of llvm-config patch ---
# Use llvm-config to bypass the faulty CMake export files.
find_program(LLVM_CONFIG_EXECUTABLE llvm-config-20 HINTS /data/data/com.termux/files/usr/bin)
if(NOT LLVM_CONFIG_EXECUTABLE)
    message(FATAL_ERROR "llvm-config-20 not found! Please ensure it is in your PATH.")
endif()

# Get version for the version check
execute_process(COMMAND ${LLVM_CONFIG_EXECUTABLE} --version OUTPUT_VARIABLE LLVM_PACKAGE_VERSION OUTPUT_STRIP_TRAILING_WHITESPACE)
string(REGEX MATCH "([0-9]+)" LLVM_VERSION_MAJOR "${LLVM_PACKAGE_VERSION}")

# Get include dirs and definitions
execute_process(COMMAND ${LLVM_CONFIG_EXECUTABLE} --cxxflags OUTPUT_VARIABLE LLVM_CXX_FLAGS OUTPUT_STRIP_TRAILING_WHITESPACE)
string(REGEX MATCHALL "-I[^ ]+" LLVM_INCLUDE_DIRS_RAW "${LLVM_CXX_FLAGS}")
foreach(dir ${LLVM_INCLUDE_DIRS_RAW})
    string(REPLACE "-I" "" dir_stripped ${dir})
    list(APPEND LLVM_INCLUDE_DIRS ${dir_stripped})
endforeach()
string(REGEX MATCHALL "-D[^ ]+" LLVM_DEFINITIONS "${LLVM_CXX_FLAGS}")

# Get the main shared library for linking
execute_process(COMMAND ${LLVM_CONFIG_EXECUTABLE} --link-shared --libs OUTPUT_VARIABLE llvm_libs OUTPUT_STRIP_TRAILING_WHITESPACE)
# --- End of llvm-config patch ---

2. Build Command:

After applying the patch and ensuring a clean build directory, the installation was successful with the following command:

LLVMLITE_SHARED=ON LLVMLITE_USE_RTTI=OFF pip install . -U --force-reinstall

Suggestion

It might be beneficial for llvmlite's build system to have a fallback or an explicit option to use llvm-config instead of find_package. This would make it more robust against packaging issues like the one found in the Termux libllvm-20 package.

Aha, and: ln -s /data/data/com.termux/files/usr/bin/llvm-config /data/data/com.termux/files/usr/bin/llvm-config-20 to make sure which version of llvm is which.

Update: the default LLVM since yesterday is LLVM version 21 in Termux, which makes it not compile at all ... Hard to downgrade to LLVM ver. 20 by now, too... LLVMLITE_SHARED=ON LLVMLITE_USE_RTTI=OFF pip install . -U

Quick results of my trying to tinker around it, Grok AI's opinions:

Disabling or removing bindings for optional instrumentation passes like InstrOrderFilePass or MemProfilerPass will not break other functions in llvmlite. These are peripheral features—specialized for niche profiling tasks like function execution order logging or memory allocation tracking—and are not dependencies for core llvmlite operations such as module creation, IR manipulation, pass management (beyond these specifics), or JIT execution via ORC. If your use case in Numba doesn't invoke these passes explicitly (which is typical for most JIT compilation workflows), the library's foundational architecture remains intact: you'll still have access to essential components like ExecutionEngine, Module, Function, and the bulk of optimization passes.

Strategically, llvmlite's design is a thin C++ binding layer over LLVM's APIs, organized modularly around categories (e.g., core.cpp for basic IR, newpassmanagers.cpp for pass bindings). The passes in question are registered (or not) via macros in PASSREGISTRY.def, and from your local AI's analysis, InstrOrderFilePass isn't even enabled there—making its include vestigial dead code. MemProfilerPass may be similar if not actively bound. Removing unnecessary includes for missing/removed headers is a low-risk cleanup that aligns with LLVM's upstream evolution, where underused features like InstrOrderFilePass were explicitly deleted in LLVM 21 (commit 2044dd07a204d4a950d3d0870c2c22604b47d2f, March 2025) because they were obsolete and superseded by better PGO tools like temporal profiling. No cascading failures occur because these aren't load-bearing; they're optional add-ons.

The real architectural hurdle is the ORC JIT incompatibility in orcjit.cpp, stemming from LLVM API breaks post-15/16. This affects the execution engine core, so it must be patched for LLVM 21 support. Here's the raw fix:

  1. For the ObjectLinkingLayerCreator lambda (line 86): LLVM removed the Triple parameter from the callback signature. Patch by dropping it from the lambda params, but capture the triple from JTMB.getTargetTriple() earlier in createLLJITBuilder (around line 70-80, before setting the creator). Then use that captured triple in the if-condition for adding the GDB plugin.

    Modified lambda:

    auto triple = JTMB.getTargetTriple();  // Add this line before builder.setObjectLinkingLayerCreator
builder.setObjectLinkingLayerCreator(
    [=](llvm::orc::ExecutionSession &session) -> Expected<std::unique_ptr<llvm::orc::ObjectLayer>> {
        if (useJitLink) {
            auto linkingLayer = std::make_unique<llvm::orc::ObjectLinkingLayer>(session);
            // The FIXME for LLVM16+ is outdated or inapplicable; no EnableDebugSupport exists on ObjectLinkingLayer. Stick with manual plugin add.
            if (triple.getObjectFormat() == Triple::ELF || triple.getObjectFormat() == Triple::MachO) {
                linkingLayer->addPlugin(
                    std::make_unique<orc::GDBJITDebugInfoRegistrationPlugin>(
                        ExecutorAddr::fromPtr(&llvm_orc_registerJITLoaderGDBWrapper)
                    )
                );
            }
            return linkingLayer;
        } else {
            // Existing else branch
        }
    }
);

  2. For the RTDyldObjectLinkingLayer constructor (line 110): LLVM added a MemoryBuffer param to the GetMemoryManagerFunction type. Patch the inner lambda to accept it (and ignore it, as SectionMemoryManager doesn't need it).

    Modified:

    auto linkingLayer = std::make_unique<llvm::orc::RTDyldObjectLinkingLayer>(
    session,
    [=](const llvm::MemoryBuffer &ObjBuffer) -> std::unique_ptr<llvm::RuntimeDyld::MemoryManager> {
        return std::make_unique<llvm::SectionMemoryManager>();
    }
);

For the missing headers (InstrOrderFile.h removed upstream; MemProfiler.h likely absent due to incomplete Termux llvm-21 packaging—common issue in Termux where dev headers aren't fully bundled): Continue removing unused includes in newpassmanagers.cpp as your local AI did, or better, wrap them in CMake-detected conditionals (check_include_files to define HAVE_XXX_H, then #ifdef around the #include and any related code). This preserves compatibility across LLVM versions without sacrificing features on older ones.

Apply these patches, rerun the build, and if MemProfiler.h persists as missing, confirm via pkg search llvm if Termux has a separate dev package (it doesn't always), or build LLVM from source for completeness. This gets you a working llvmlite on LLVM 21 without architectural compromise. For your PR, frame it as LLVM 21 compatibility updates, noting the removed pass and API shifts.

I was able to successfully build llvmlite on Termux with LLVM 21.1.3 after making a few changes to the source code. Here is a summary of the steps I took:

  1. Adapted the ffi/CMakeLists.txt patch: The original patch was hardcoded to use llvm-config-20. I updated it to use the generic llvm-config to dynamically detect the installed LLVM version.
  2. Dynamically detected the LLVM version: I modified ffi/CMakeLists.txt to dynamically determine the supported LLVM version from llvm-config --version.
  3. Patched ffi/orcjit.cpp: I moved the extern "C" declaration for llvm_orc_registerJITLoaderGDBWrapper to the top of the file, and included the llvm/ExecutionEngine/Orc/Debugging/DebuggerSupport.h header. I also fixed the scope of the JITTargetMachineBuilder and updated the RTDyldObjectLinkingLayer constructor to accept the MemoryBuffer parameter.
  4. Patched ffi/newpassmanagers.cpp: I removed the includes for llvm/Transforms/Instrumentation/InstrOrderFile.h and llvm/Transforms/Instrumentation/MemProfiler.h, which are no longer present in LLVM 21. I also introduced a new macro, FUNCTION_PASS_WITH_ARGS, to correctly handle the LintPass(false) constructor.
  5. Cleaned the build directory: I removed the build/ directory and CMakeCache.txt to prevent issues with stale artifacts.
  6. Ran the build with the correct environment variables: I executed the build with the command LLVMLITE_SHARED=ON LLVMLITE_USE_RTTI=OFF python ffi/build.py.

These changes allowed me to successfully build llvmlite with LLVM 21.1.3 on Termux. I have documented the entire process in a GEMINI.md file in my fork of the repository.

Plus the nature of these fixes:

✦ The patches I created were a mix of both. I made llvmlite more universal by adapting it to the Termux environment and the newer LLVM 21 API, but I also had to disable some functionality due to the incomplete LLVM installation on Termux.

Here's a breakdown:

Universal/Adaptation:

  • ffi/CMakeLists.txt: The changes I made here were to make the build system more flexible. Instead of hardcoding the LLVM version, I made it dynamically detect the installed version. This is a good practice that makes the build system more robust and adaptable to different environments.
  • ffi/orcjit.cpp: The patches I applied here were to adapt the code to the new LLVM 21 API. The LLVM API is not stable, and changes between versions are common. My patches ensure that llvmlite can still communicate with the JIT compiler in LLVM 21.
  • ffi/newpassmanagers.cpp: The changes I made here were to adapt the code to the new LLVM 21 API. The LintPass constructor changed in LLVM 21, and my patch ensures that llvmlite calls it correctly.

Disabling:

  • ffi/newpassmanagers.cpp: I removed the includes for llvm/Transforms/Instrumentation/InstrOrderFile.h and llvm/Transforms/Instrumentation/MemProfiler.h. These headers are not available in the Termux LLVM 21 package, and the features they provide are not essential for the core functionality of llvmlite. By removing them, I was able to get the build to succeed, but I also disabled the InstrOrderFilePass and MemProfilerPass passes.

In summary, the patches I created were a pragmatic solution to a complex problem. I made llvmlite more universal by adapting it to the Termux environment and the newer LLVM 21 API, but I also had to disable some non-essential features to get the build to succeed. The ideal solution would be to have a complete LLVM 21 installation on Termux, but in the absence of that, my patches provide a viable workaround.

Note mostly to self:

Alternative is to: apt install -o Dpkg::Options::="--force-overwrite" python-llvmlite (sic!) to get:

Then slightly downgrade numba to e.g.: pip install numba==0.61.0 -v (you need to experiment with these pinned versions to match e.g. your numpy too.)

And then run most of the stuff with: export NUMBA_DISABLE_JIT=1 so as to disable Just In Time compilation errors. YMMV ...

If you have to do this to avoid JIT compilation errors, then it sounds a lot like Numba isn't actually working in this setup.

Re:

Yes, it looks like. For now, most of the chained below misbehave too, whaever pinned version I try, at least in pure (not prooted) Termux, aka aarch64 Android:

I guess Termux users need to patiently wait for some apt's packaged version of llvmlite then...

I don't know Termux - is it bascially like a Linux aarch64 distro? If so, is there a reason that aarch64 wheels cannot be used?

gmarkall avatar Oct 20 '25 16:10 gmarkall

Re:

Termux - is it bascially like a Linux aarch64 distro?

Uhm, but with quirks, mostly around the missing glibc stuff (not material here, methinks), see: https://wiki.termux.dev/wiki/Main_Page for starters.

Re:

is there a reason that aarch64 wheels cannot be used?

Yes, a banal one: because it compiles anew and fails before (llvm20) and now (llm21), see : https://github.com/numba/llvmlite/issues/1328#issuecomment-3400719257 just hereinabove ;)

The fixes to llvm20 version made it install but then with some runtime probs, while now, at Termux default llvm21: I gave up with trying to patch it, as too deep changes needed, also see above (Grok Ai's summary) for details.

Manamama avatar Oct 21 '25 14:10 Manamama

This sounds like it's not using the wheel, but the sdist. In the first line of the output in that comment, it's running bdist_wheel to build a wheel rather than using a published wheel. Do you know why it's not using the published wheel?

I don't think Grok's summary is adding any clarity at all here. (I find this often to be the case when faced with an unedited / unrefined AI summary added to an issue where the root cause is already unclear)

gmarkall avatar Oct 22 '25 07:10 gmarkall

Do you know why it's not using the published wheel?

Answering my own question: likely because it uses the bionic libc so a manylinux wheel may not be usable.

gmarkall avatar Oct 22 '25 08:10 gmarkall

Re:

I guess as the wheels that exist (are published) are buggy, as per above, hence my very Issue herein. Or as my (admittedly, somehow bespoke, as full of onnx or ctranslate2 stuff that supposedly should not run in Droid, but somehow does, after a tweak or two to some recondite cmake switches) OS is weird by now. Steps to reproduce:

  • Get Android with Termux. (Or an Android image and install Termux)
  • Run:

but see https://github.com/numba/llvmlite/issues/1328#issue-3505961278 ("the Root Cause") pacem Gemini AI, in turn, for the first patch needed, as juggling the apt reinstall of this llvm-* related stuff does not help; one needs to go for the jugular (the llvmlite code fixes, which worked until recently, also see above).

Manamama avatar Oct 22 '25 11:10 Manamama

Note for self mostly, this solves the problems of the missing .so files in LLVM 21 and maybe older ones, see above. Run:

apt install libpolly
apt install libllvm-static

Check if so via: locate /libLLVMDemangle.a and such

Here's a working solution for building llvmlite from source on Termux with LLVM 21.1.x, based on the discussions and findings in this thread.

The core issues were:

  1. LLVM API Changes: llvmlite's C++ code needed adjustments for LLVM 21's API.
  2. Faulty CMake Exports: The standard find_package(LLVM) mechanism on Termux was problematic.
  3. Incomplete Patch Logic: The initial patch, while addressing API changes, broke CMake's linking stage by relying on functions (llvm_map_components_to_libnames) that were no longer defined after bypassing find_package(LLVM).
  4. Incorrect LLVM Component Listing: The patched CMakeLists.txt had an incorrect list of LLVM components for static linking, leading to linker errors.
  5. RTTI Configuration: The build process required explicit RTTI configuration.

Step 1: Apply the LLVM 21 Compatibility Patch

This patch addresses the C++ API changes in LLVM 21. It modifies ffi/CMakeLists.txt, ffi/newpassmanagers.cpp, and ffi/orcjit.cpp. (This patch should be placed in the root of the llvmlite directory, e.g., as llvmlite-llvm21-compat.patch)

Step 2: Manually modify ffi/CMakeLists.txt

The above patch introduced a problem where llvm_map_components_to_libnames was called but not defined. This manual modification replaces that logic with a direct llvm-config --libs call. It also updates the list of LLVM components for static linking to reflect correct component names found via llvm-config --components.

Oh, but the regular wheels still fail as of now: LLVMLITE_SKIP_LLVM_VERSION_CHECK=1LLVMLITE_SHARED=ON LLVMLITE_USE_RTTI=OFF pip install llvmlite -U --force-reinstall -v, so git cloning and hacks be needed, so I keep above.
