macOS: dyld RPath Library not loaded in 2.6.0 #2316

Open ax3l opened 4 years ago

ax3l commented 4 years ago

Describe the bug I am currently transitioning to ADIOS 2.6.0 in our CI and encounter problems at runtime with the new split libraries on macOS 10.13 and 10.14 of the form:

dyld: Library not loaded: @rpath/libadios2_c.2.dylib
  Referenced from: /Users/travis/build/bin/MyBinary
  Reason: image not found

To Reproduce I use a spack-installed ADIOS 2.6.0 and built against it with CMake. I run into issues as seen in: https://travis-ci.com/github/openPMD/openPMD-api/builds/170615793

We use the native C++11 API of ADIOS2. Other dependencies in our downstream CMakeLists.txt might activate the C language in CMake, but we do not use the ADIOS2 C bindings directly.

Expected behavior Did build & run with ADIOS 2.5.0 :)

Desktop (please complete the following information):

Additional context

I switched now to the new adios2::cxx11 and adios2::cxx11_mpi targets and get:

dyld: Library not loaded: @rpath/libadios2_cxx11.2.dylib
  Referenced from: /Users/travis/build/bin/MyBinary

@chuckatkins @bradking do you have an idea what's off on macOS? This one is a blocker for us to migrate to ADIOS 2.6.0 (and with it finalizing complex support for our users).

bradking commented 4 years ago

We need to figure out where that @rpath/ reference is coming from.

I use a spack-installed ADIOS 2.6.0

I just ran spack install adios2@2.6.0 on macOS and found that LC_ID_DYLIB in opt/spack/darwin-catalina-x86_64/clang-11.0.0-apple/adios2-2.6.0-ioxjevk4au455pt4rop2smac3kpcbgv5/lib/libadios2_cxx11.2.6.0.dylib is an absolute path and does not mention @rpath anywhere. Is that the case for yours too? You can find that file and run otool -l $file to see.

Thanks, my libadios2_cxx11.2.dylib looks like this. CI: https://travis-ci.com/github/openPMD/openPMD-api/jobs/349960561

@ax3l thanks. Your libadios2_cxx11.2.dylib indeed has LC_ID_DYLIB set to @rpath/libadios2_cxx11.2.dylib. That is different than on my machine's spack installation. Does spack have any options for that?

What did the adios2 .dylib files in ADIOS2 2.5 have for you?

ax3l commented 4 years ago

Thanks @bradking. In ADIOS2 2.5.0 the symbols looks like this: https://travis-ci.com/github/openPMD/openPMD-api/builds/172164002

both use the same (latest) version of Spack to install.

@ax3l thanks. That ADIOS 2.5 library has LC_ID_DYLIB set to /Users/travis/.cache/spack/opt/spack/darwin-mojave-x86_64/clang-11.0.0/adios2-2.5.0-sf6eyfn6xjlwvbvgs7dajgdpvs6ihrnb/lib/libadios2.2.dylib which is expected and does not mention @rpath/.

It also matches what I see on my installations for ADIOS 2.5 and 2.6, which I installed on macOS in a brand new spack tree using spack install adios2@2.5.0 and spack install adios2@2.6.0. So the question remains: why does your spack-installed ADIOS2 2.6 use @rpath while mine does not? That is a question for a spack expert.

ax3l commented 4 years ago

Intriguing, thank you for testing this. Just to collect all data: which version of CMake did you use? With CMake 3.12.0 I can reproduce this on macOS 10.13 (AppleClang 10.0) and 10.14 (AppleClang 11.0) on Travis-CI and set the following Spack configs: https://github.com/openPMD/openPMD-api/tree/3ff42bedbef2ab00457d26f5fd5f9d23dc7dcfe8/.github/ci/spack . None of them should be related to rpaths but I build ADIOS2 with the variant modifcations ~zfp ~sz ~png ~dataman ~python ~fortran ~ssc.

This is the Spack CMake-related RPath info I can find in the docs:

Also inquired upstream.

There is the logic in build_environment.py to create SPACK_COMPILER_IMPLICIT_RPATHS, SPACK_COMPILER_EXTRA_RPATHS, SPACK_RPATH_DIRS, and SPACK_RPATH_DEPS. If you follow those you should see how they were constructed. If the library is pointing to itself, I would guess that is coming from SPACK_RPATH_DIRS or SPACK_RPATH_DEPS (someone forgot to exclude the root from a DAG traversal) or it could be the package itself.

bradking commented 4 years ago

I ran those spack install commands on macOS 10.15 with AppleClang 11.0. CMake 3.17.0 was in my PATH.

ax3l commented 4 years ago

Still had no time to debug this inside Spack, but will work-around this for now by building a adios2 ~shared ADIOS2 in our CI to keep going.

Now get an interesting Library not loaded: @rpath/libbz2.1.dylib when running an executable that links against the dynamic libopenPMD, which in turn was built against a static adios2. Will disable that as well via adios2 ~bzip2.

manauref commented 2 years ago

Any updates on this? Is the Mac python bindings not working/usable at the moment because of this? I haven't been able to install/use them.

williamfgc commented 2 years ago

@manauref in case you don't need the latest development, there is the adios2 brew package that @ax3l put together. Hope it helps.
