Do you have the 10.9 sdk installed in /opt?

See CONDA_BUILD_SYSROOT in conda _build_config.yaml for the exact location. You can get this from many different places. One is https://github.com/phracker/MacOSX-SDKs

We currently can't just provide packages due to licensing concerns. Thanks Apple.

You're right, I didn't have the sdk installed. Did so, and adjusted conda_build_config.yaml location accordingly. Incidentally, there was a full 10.9 sdk installed to miniconda/conda-bld/llvm-suite_1507415239196/work/bootstrap/MacOSX10.9.sdk/System at conda-build time that file-structure-wise is identical to the github sdk 10.9 repo.

Unfortunately, error was still the same. "Fixed" it by adding an extra library to cctools_build/ld64/Makefile LTO_LIBS = -lxml2 -lpthread -lLTO. Also had to edit cctools_build_libtool/ld64/Makefile to add $(top_srcdir)/../prefix to MYINCLUDES & MYLDFLAGS so that it could find tapi/tapi.h and ltapi (though this was during a hand-makeing jaunt and hasn't been confirmed in a linear compilation sequence).

The next blocking error is the signature problem below. In occurs in cctools_build_final and at that time, it has already successfully built the file twice (immediately below). The patch that toggles qsort_r signatures is present in the source, so this is clearly an issue that's being managed by the build. Any notion why macho_relocatable_file.cpp could be failing to build only for "_final" (of "", "_libtool", & "_final")?

I probably would not attempt to build these compilers on any macOS other than 10.9. You'll be in for a tough time if you do. I did try once but it's kind of not worth it since you want to guarantee the compilers work on and generate code for 10.9 and building them on anything else risks breaking that guarantee (same as how the new gcc compilers were built on CentOS6).

The macOS compilers built with this recipe on conda defaults have omp.h (it is in the llvm-openmp package as is lib/libomp.dylib):

tar -tf /opt/conda/pkgs/llvm-openmp-4.0.1-hda82c8b_0.tar.bz2 
info/hash_input_files
info/files
info/index.json
info/paths.json
info/about.json
info/hash_input.json
info/LICENSE.txt
info/git
info/test/test_time_dependencies.json
info/recipe/install-openmp.sh
info/recipe/conda_build_config.yaml
info/recipe/meta.yaml
lib/clang/4.0.1/include/omp.h
info/recipe/build.sh
lib/libomp.dylib

I also tested these just now for building r-data.table which requires OpenMP (https://github.com/Rdatatable/data.table/wiki/Installation#openmp-enabled-compiler-for-mac)

in build.sh:

if [[ ${HOST} =~ .*darwin.* ]]; then
  echo "CC=${CC} -fopenmp" > ~/.R/Makevars
fi
$R CMD INSTALL --build .
if [[ ${HOST} =~ .*darwin.* ]]; then
  rm -rf ~/.R
fi

You did warn us :-)

Thanks very much, @mingwandroid. Added llvm-openmp to build and runtime, and my original package built like a charm. Now to impose -fopenmp=iomp5 ...

Warning to future thread readers: to build clang packages, really must be on 10.9. Even with 10.9 sdk, neither 10.10 nor 10.11 will do.

mingwandroid commented on June 25, 2024

I can probably fix that but perhaps only if these compilers are used as a build dependency and that's cyclic and that won't work either so we'd need a hack.

Or maybe I can fix it without needing these compilers but it's unlikely to be looked at any time soon.

loriab commented on June 25, 2024

No cause to "fix" them (allow compilation away from 10.9) on my part. I was only trying to build the compilers so that I could install an omp.h, and you solved that by alerting me to package llvm-openmp.

nehaljwani commented on June 25, 2024

All of the missing symbols that are being reported for libxar.a come from libicuuc.58 .

from aggregate.

nehaljwani commented on June 25, 2024

And the requirement on libicuuc is coming from the statically linked libxml2.a in libxar.a

from aggregate.

nehaljwani commented on June 25, 2024

If I make sure that the build uses https://repo.anaconda.com/pkgs/main/osx-64/xar-1.6.1-h50205bb_0.tar.bz2 , then the link error goes away.
