Building C3 on ubuntu fails

[tonis2]

Hei,

I'm trying to build C3 dev on ubuntu.

Cloned the repo, entered the folder, created build folder, then ran cmake ..

Below is what error I'm getting, the build process some-why deletes the ´/lib` folder inside c3 folder

C3C version: 0.6.0
-- Found LLVM 18.1.8
-- Using LLVMConfig.cmake in: /usr/lib/llvm-18/cmake
-- Libraries located in: /usr/lib/llvm-18/lib
-- LLVM was built with RTTI
-- using find_library
CMake Error at CMakeLists.txt:209 (file):
  file COPY cannot find "/var/home/default/Documents/c/c3c/lib": No such file
  or directory.

Could this somehow have caused it: file(REMOVE_RECURSE ${CMAKE_BINARY_DIR}/lib)

[lerno]

If the CMAKE_BINARY_DIR is set to the source dir, then that could happen.

Try it now.

It's better now, but I'm still getting some errors

That means LLD is missing. You need that library as well.

[MegaHakkero]

passing -DC3_LINK_DYNAMIC=true to cmake will make it build if your system LLVM/LLD doesn't include static libraries. this is needed on some distros like arch

I'm going to close the issue for now, got it fixed
