Compiling dependency foonathan_memory for QNX [6215]

[briansoe66]

I am trying to build Fast-RTPS for QNX. I am able to build Fast-CDR and Fast-RTPS, but I cannot build foonathan_memory. mutex and experimental/memory_resource are not found. Has anyone been able to build foonathan_memory for QNX (7.0.0), and could share how?

I've attached my qnx toolchain and cmake error log.

cmake_toolchain_and_error_log.zip

cmake -DCMAKE_TOOLCHAIN_FILE=../qnx-tool-chain.cmake -DCMAKE_INSTALL_PREFIX=../../install -DCMAKE_BUILD_TYPE=Release -DFOONATHAN_MEMORY_BUILD_EXAMPLES=OFF ..

I believe the issue is that:

• QNX does not contain <experimental/memory_resource.h>
• therefore, foonathan_memory must be built with FOONATHAN_MEMORY_BUILD_TOOLS=OFF
• this results in container_node_sizes_impl.hpp being empty, and shared_ptr_stateful_node_size being undeclared. I've created an issue for this

Fast-RTPS release 1.8.1 does not have a dependency on foonathan_memory. Hopefully the foothan_memory QNX depency issues will be resolved before 1.9.0

Cross compiling is broken in general for foonathan-memory. There are some errors in it's CMakeLists.txt such as checking the non-existant CMAKE_CROSS_COMPILING variable instead of CMAKE_CROSSCOMPILING. Bad news of some of us who develop and build on X86-64 but deploy on a different target

Edit: Adding related issue in foonathan-memory for reference: foonathan/memory#51

For what it's worth, https://github.com/cvilas/fastrtps_xctest provides a basic repo to test cross compilation. This works perfectly fine for FastRTPS v1.8 and below and I have used something similar to build for NVidia TX2, Android, etc. With the new foonathan-memory dependency, this fails

There have been several improvements related with cross-compilation to the foonathan/memory repo. I guess they might be useful in cross-compiling for QNX.

@cvilas @briansoe66 could you check on your side?

Edit:
To be more precise, take a look at foonathan/memory#59 and foonathan/memory#60

[cvilas]

@MiguelCompany I can confirm that memory and Fast-RTPS can now be cross compiled after following the structure of cmake cross compilation toolchain setup in foonathan/memory#60

[briansoe66]

@MiguelCompany, I am still unable to compile foonathan memory on QNX using foonathan_memory_vendor master or foonathan_memory master :(

I have created issue foonathan/memory#72 (comment)

@briansoe66 Just answered there

I'm closing this issue in favor of foonathan/memory#72. Feel free to comment or reopen at any time
