macOS-arm64 - problem linking libraries

[hans]

Hi,

I am using CodeLite on macOS 11.2.1 with an M1 chip. I have a C++ project that links to libraries (openmpi and hypre). The compilation works fine, but when trying to link to the libraries, I get the following error message:

ld: warning: ignoring file /usr/local/hypre/lib/libHYPRE.a, building for macOS-x86_64 but attempting to link with file built for macOS-arm64
ld: warning: ignoring file /usr/local/openmpi/lib/libmpi.dylib, building for macOS-x86_64 but attempting to link with file built for macOS-arm64

I am pretty sure that I am actually building for macOS-arm64, compiling the project outside CodeLite using a make file works fine. I was wondering whether this issue could be possibly fixed from CodeLite's side? Appreciating the help!

Can you paste the complete build log output? (see my signature)

Hi, thanks for the follow up! Since the complete build log output is too long for the forum, it can be found under this dropbox link: https://www.dropbox.com/s/jdpbgc8epcqy0 ... t.txt?dl=0.

In case it helps, the project I try to compile and its source code can be found here: https://github.com/REEF3D/REEF3D

The linker clearly gives you a hint on what is broken:

Code: Select all

ld: warning: ignoring file /usr/local/openmpi/lib/libmpi.dylib, building for macOS-x86_64 but attempting to link with file built for macOS-arm64

Your libmpi.dylib is x86_64 while your code is compiled for arm64
Note that this is not a C++ forum, so you should take these kind of questions to the proper forum

Thanks for taking the time to have a look! Yes, I did see the linker output. The thing is, libmpi.dylib is not x86_64. It was natively compiled for macOS-arm64. Compiling the same project with a makefile, linking to the same libmpi.dylib library (and all other libraries), works fine. That is why I guess, the error is related to CodeLite or the way it is trying to link the libraries.

Just wanted to give feedback and happy to report: Using the Codelite 16.2 version installed from brew finally fixes this persistent issue on Mac with arm64.
