Generically, building druntime should be fine, you'll need a sufficiently old enough version of osx to run 32-bit binaries - I forget when they dropped multilib support, around 10.9? - which means that there might be some missing symbols reported when building Phobos (posix_memalign might be one). oh, thank you for your reply. I'll repost to the LDC group.
Building i386 D runtime on OS X
Hello, I am following the instructions here: https://wiki.dlang.org/Building_LDC_runtime_libraries I'm on OSX and need a ELF D RTL for i386. I've used HomeBrew to install x86_64-elf-gcc, ninja and cmake. The command I'm issuing is: `CC=/usr/local/Cellar/x86_64-elf-gcc/12.2.0/bin/x86_64-elf-gcc ldc-build-runtime --ninja --dFlags="-mtriple=i386-none-elf" ` I'm getting the below result. Is there a known way to get past the `search_paths` issue? Or perhaps a better way to build the i386 elf RT on OS X? > CC=/usr/local/Cellar/x86_64-elf-gcc/12.2.0/bin/x86_64-elf-gcc ldc-build-runtime --ninja --dFlags="-mtriple=i386-none-elf" .: Creating build directory: ldc-build-runtime.tmp .: Downloading LDC source archive: https://github.com/ldc-developers/ldc/releases/download/v1.30.0/ldc-1.30.0-src.zip .: Invoking: cmake -DLDC_EXE_FULL=/usr/local/Cellar/ldc/1.30.0_1/bin/ldc2 -DDMDFE_MINOR_VERSION=100 -DDMDFE_PATCH_VERSION=1 -DD_EXTRA_FLAGS=-mtriple=i386-none-elf -G Ninja /Users/tom/projects/ados/src/ldc-build-runtime.tmp/ldc-src/runtime -- The C compiler identification is GNU 12.2.0 -- Checking whether C compiler has -isysroot -- Checking whether C compiler has -isysroot - yes -- Checking whether C compiler supports OSX deployment target flag -- Checking whether C compiler supports OSX deployment target flag - no -- Detecting C compiler ABI info -- Detecting C compiler ABI info - failed -- Check for working C compiler: /usr/local/Cellar/x86_64-elf-gcc/12.2.0/bin/x86_64-elf-gcc -- Check for working C compiler: /usr/local/Cellar/x86_64-elf-gcc/12.2.0/bin/x86_64-elf-gcc - broken CMake Error at /usr/local/Cellar/cmake/3.24.2/share/cmake/Modules/CMakeTestCCompiler.cmake:69 (message): The C compiler "/usr/local/Cellar/x86_64-elf-gcc/12.2.0/bin/x86_64-elf-gcc" is not able to compile a simple test program.
