I can confirm this issue. It uses "/usr/lib/libffi.so" even though it's building for abi_x86_32.

The issue lies somewhere in the detection of the FFI_LIBRARY_PATH (not _DIR). As you can see below, the "FFI_LIBRARY_DIR:PATH=/usr/lib32" looks fine, but the resulting "FFI_LIBRARY_PATH:FILEPATH=/usr/lib/libffi.so" is broken. The appropriate cmake lines are in "llvm-9999/cmake/config-ix.cmake": find_library(FFI_LIBRARY_PATH ffi PATHS ${FFI_LIBRARY_DIR}) if( NOT FFI_LIBRARY_PATH ) message(FATAL_ERROR "libffi is not found.") endif() Grepping for FFI_LIB after the unsuccessful build # grep -Ir FFI_LIBRARY_ . ./llvm-9999-abi_x86_64.amd64/CMakeCache.txt:FFI_LIBRARY_DIR:PATH=/usr/lib64 ./llvm-9999-abi_x86_64.amd64/CMakeCache.txt:FFI_LIBRARY_PATH:FILEPATH=/usr/lib64/libffi.so ./llvm-9999-abi_x86_x32.x32/CMakeCache.txt:FFI_LIBRARY_DIR:PATH=/usr/libx32 ./llvm-9999-abi_x86_x32.x32/CMakeCache.txt:FFI_LIBRARY_PATH:FILEPATH=/usr/lib/libffi.so ./llvm-9999-abi_x86_32.x86/CMakeCache.txt:FFI_LIBRARY_DIR:PATH=/usr/lib32 ./llvm-9999-abi_x86_32.x86/CMakeCache.txt:FFI_LIBRARY_PATH:FILEPATH=/usr/lib/libffi.so ./llvm-9999/CMakeLists.txt:set(FFI_LIBRARY_DIR "" CACHE PATH "Additional directory, where CMake should search for libffi.so") ./llvm-9999/lib/ExecutionEngine/Interpreter/CMakeLists.txt: target_link_libraries( LLVMInterpreter PRIVATE ${FFI_LIBRARY_PATH} ) ./llvm-9999/docs/CMake.rst: FFI_LIBRARY_DIR to the directories where ffi.h and libffi.so can be found, ./llvm-9999/cmake/config-ix.cmake: find_library(FFI_LIBRARY_PATH ffi PATHS ${FFI_LIBRARY_DIR}) ./llvm-9999/cmake/config-ix.cmake: if( NOT FFI_LIBRARY_PATH ) ./llvm-9999/cmake/config-ix.cmake: list(APPEND CMAKE_REQUIRED_LIBRARIES ${FFI_LIBRARY_PATH}) ./llvm-9999/cmake/config-ix.cmake: list(REMOVE_ITEM CMAKE_REQUIRED_LIBRARIES ${FFI_LIBRARY_PATH}) Is this related to the recent requirement-bump of cmake to 3.4.3?
This is caused by bug #338492. Patching cmake to search lib32 in addition lib allows llvm to compile for ABI_X86="32 64". I imagine ABI_X86="x32" will need a similar fix.
Unless you are able to provide a good patch, I don't know if I'll be able to look at it before it hits a release. And if it does, I don't know how long it's gonna delay it ;-).
I sent the patch to the CMake list (has trivial merge conflicts for 3.5): http://public.kitware.com/pipermail/cmake-developers/2016-June/028621.html However, similar patches have been available for older CMake versions in bug #338492 (and upstream bug linked there) but have been rejected as they (and my patch) still hard-code lib32.

Nice work, your patch seems to be upstreamed: https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=896ad251 Can you easily extend it for x32? I am personally interested in getting cmake finally working on x32. Can you provide cmake patches which could be used on the gentoo version? Or do you intend to backport it to 3.4 / 3.5 on upstream?
Created attachment 437088 [details, diff] CMake 3.5 patch Sorry, I don't plan to spend more time on this right now - and I don't have any x32 installs to test on anyway. I have attached the 3.5 patch and there is a patch for 2.8 in the cmake bug report. No idea if either of these apply for 3.4.

No idea if either of these apply for 3.4. I applied the patch on top of cmake 3.4.3 without problems. With this new patched version of cmake, I get an improvement over the result before: /llvm-9999-abi_x86_64.amd64/CMakeCache.txt:FFI_LIBRARY_DIR:PATH=/usr/lib64 /llvm-9999-abi_x86_64.amd64/CMakeCache.txt:FFI_LIBRARY_PATH:FILEPATH=/usr/lib64/libffi.so /llvm-9999-abi_x86_x32.x32/CMakeCache.txt:FFI_LIBRARY_DIR:PATH=/usr/libx32 /llvm-9999-abi_x86_x32.x32/CMakeCache.txt:FFI_LIBRARY_PATH:FILEPATH=/usr/lib32/libffi.so /llvm-9999-abi_x86_32.x86/CMakeCache.txt:FFI_LIBRARY_DIR:PATH=/usr/lib32 /llvm-9999-abi_x86_32.x86/CMakeCache.txt:FFI_LIBRARY_PATH:FILEPATH=/usr/lib32/libffi.so Now we "only" need to write a similar patch for x32...
Thanks a lot for your effort. I'm going to move the relevant bits to the original bug. *** This bug has been marked as a duplicate of bug 338492 ***
