[bug] Failure to cross-compile OpenSSL for QNX
Environment details
Operating system: Ubuntu 22 04 GCC: 10.5.0 Conan: 1.59.0 Python: 3.10.12 Cmake: 3.28.1
Steps to reproduce
- Download and install QNX SDP toolchain into local system.
- Source SDP toolchain and capture environment variables
- Add environment variables to QNX Conan profile.
- Execute Conan install for cross-compile, using build/host profiles.

Simple Conan Install Command
conan install openssl/3.2.1@ -pr:h=conan-profile-host -pr:b=conan-profile-build --build -r conancenter
Results in Error
"cc: Can't specify -P, -C, -E, -c or -S with -o and have multiple files"
Doing the exact same process for many other Yocto based SDK toolchains, they can all build OpenSSL. I have no clue where to go from here, not much to go on from the Internet. Any assistance would be appreciated. Thanks

Hi @MikeyH84
Thanks for your report.
Unfortunately, I don't have qcc to test it here.
Download and install QNX SDP toolchain into local system.
Is there a free download available? Do you have a link?
But maybe some hint that could be related: [env] is deprecated in favor of [buildenv]. Only [buildenv] is 2.0-ready, so this is the recommended way. It is possible that some recipes in ConanCenter do only follow [buildenv] but no longer [env]. Check https://docs.conan.io/1/reference/profiles.html#buildenv
Doing the exact same process for many other Yocto based SDK toolchains
What does this mean? Are you able to build many other Conan packages from ConanCenter with this same configuration?
A good way to quickly check if things work is using conan new hello/0.1 -m=cmake_lib or -m=autotools_lib to have out of the box templates that should work with conan create . -pr:b=mybuild -pr:h=myhost. Does your profiles configuration work fine for these templates?
Hi @memsharded,
sorry for the late reply, was trying some things out.
So cross-compiling with QNX in Conan, from what little information I can find online, seems that Conan profiles are not enough on their own. Even though I've put the QNX source'd environment variables into the profiles.
I think CMake error cc: Can't specify -P, -C, -E, -c or -S with -o and have multiple files is just indicating that CMake was configured badly, and whatever compile commands were attempted are broken.
I was able to get past this error by adding a QNX toolchain representing the TARGET.
You're idea of building helloworld was good, as it found I needed the QNX toolchain.
I also added the Conan profile section buildenv as per your advice.
I have been running tests attempting to build helloworld, protobuf, and openssl, all using the same profiles and toolchains:
Conan create/install commands
conan create . \
-pr:h=conan-profile-host \
-pr:b=conan-profile-build
conan install protobuf/3.21.12@ \
-pr:h=conan-profile-host \

This combination succesfully builds both helloworld and Protobuf for QNX. OpenSSL fails with the following error:
${LDCMD:-cc} -fPIC -g -fPIC -g -fPIC -L/root/.conan/data/zlib/1.3.1/_/_/package/4db21118e429c251335f35fd1e6bdd64269d69af/lib \

libssl.a libcrypto.a -lz -lsocket -latomic
The linker cannot find -lsocket

Deep dive
Comparing a successful x86_64 OpenSSL build and unsuccessful QNX build:
x86_64
${LDCMD:-gcc} -pthread -m64 -m64 -fPIC -g -Wa,--noexecstack -m64 -fPIC -g -fPIC -L/root/.conan/data/zlib/1.3.1/_/_/package/75e99b627c196b65c439728670655ec3c366b334/lib -m64 -m64 \
-o util/quicserver \
util/quicserver-bin-quicserver.o \
libssl.a libcrypto.a -lz -ldl -pthread
QNX
${LDCMD:-cc} -fPIC -g -fPIC -g -fPIC -L/root/.conan/data/zlib/1.3.1/_/_/package/4db21118e429c251335f35fd1e6bdd64269d69af/lib \
-o util/quicserver \
util/quicserver-bin-quicserver.o \
libssl.a libcrypto.a -lz -lsocket -latomic
Note the only major difference is x86_64 does not append -lsocket to the linker.
Can see the OpenSSL Conan recipe doing so here
Just to clarify, socket is part of the QNX SDP I am using

@memsharded I think I need to pass the CMake toolchain to OpenSSL. Am I doing that correctly in my profile? Its almost like the OpenSSL does not know about my QNX toolchain containing the CMake QNX_TARGET variable.
Thanks
Hi, I am facing issue related openssl cross compiling. @memsharded [https://github.com/conan-io/conan-center-index/issues/24968]
Hi @vineethabc - thanks for providing additional details.
I think I need to pass the CMake toolchain to OpenSSL
OpenSSL uses its own build system, which is not CMake - so I suspect the recipe itself may need to be fixed to support QNX. We do not have a QNX SDP available to test, so we rely on community contributors for this. I think upstream OpenSSL actually doesn't currently support QNX, as per:
- https://github.com/openssl/openssl/pull/5756/files
- https://github.com/openssl/openssl/issues/22257
If it has even worked with the Conan Center recipe, it's due to community contributions.
-lsocket should be correct in QNX
Based on the logs you have provided:
${LDCMD:-cc} -fPIC -g -fPIC -g -fPIC -L/root/.conan/data/zlib/1.3.1/_/_/package/4db21118e429c251335f35fd1e6bdd64269d69af/lib \
-o util/quicserver \
util/quicserver-bin-quicserver.o \
libssl.a libcrypto.a -lz -lsocket -latomic
/usr/bin/ld: skipping incompatible /root/.conan/data/zlib/1.3.1/_/_/package/4db21118e429c251335f35fd1e6bdd64269d69af/lib/libz.a when searching for -lz
/usr/bin/ld: cannot find -lsocket: No such file or directory
The issue seems to be that it is using /usr/bin/ld - which is probably not correct and it should be using a file from the QNX SDK instead.
So I think the recipe needs to be changed, at the very least so that it tries to use qcc as the compiler.
If I remember correctly, as an alternative, QNX does come with OpenSSL https://www.qnx.com/developers/docs/7.1/index.html#com.qnx.doc.core_networking/topic/security_OpenSSL.html
So you may choose to tell Conan to assumpe it is a system library: https://docs.conan.io/2/reference/config_files/profiles.html#platform-requires
in your profile:
[platform_requires]
openssl/3.2.1
for a lot of recipes this should "just work" - but let us know if that is not the case!
