Hi

I get this error, with no further explenations ...

cmake ../dale
CMake Error at CMakeLists.txt:17 (message):
  Unable to execute '/usr/local/opt/llvm/bin/llvm-config': 0
The mentioned executable exists totheger with a bunch of of other installs.
-- Configuring incomplete, errors occurred!

ls /usr/local/opt/ | grep llvm
llvm
llvm@11
llvm@14
llvm@15
llvm@16

Thanks for this. It looks like the llvm-config check in the CMake file is not correct for macOS at least, so it's been disabled. It should be possible to build it now.

thanks
I've tried it again, here is what I get

cmake ../dale

/usr/local/opt/llvm/bin/llvm-config --version

It looks like it's still using the old CMakeLists.txt file. Could you try removing the existing checkout, re-cloning the repository, and building again?

commented

albeit installed, cmake doesn't seem to find the proper llvm installation

...
-- System processor: x86_64
-- System version: 22.4.0
CMake Error at CMakeLists.txt:93 (message):
  LLVM <= 14.0 is required.

So when given the path manually it is continuing

 5 #find_program(LLVM_CONFIG llvm-config DOC "path to llvm-config")
  6 set(LLVM_CONFIG "/usr/local/opt/llvm@14/bin/llvm-config")
  7 set(CLANG "/usr/local/opt/llvm@14/bin/clang")
  8 #find_program(CLANG clang DOC "path to clang")

but then fails again not finding lib-ffi which resides in ' /usr/local/opt/libffi/'

...

I think it worked now after doing this 2 things

set the path to find the pc files
export PKG_CONFIG_PATH="/usr/local/opt/libffi/:/usr/local/opt/libffi/lib/pkgconfig/:$PKG_CONFIG_PATH"

still failed with this

finally symbolic linking seems to solve it
ln -s /usr/local/Cellar/libffi/3.4.4/lib /usr/local/Cellar/libffi/3.4.4/lib-lffi

5 #find_program(LLVM_CONFIG llvm-config DOC "path to llvm-config")
6 set(LLVM_CONFIG "/usr/local/opt/llvm@14/bin/llvm-config")
7 set(CLANG "/usr/local/opt/llvm@14/bin/clang")
8 #find_program(CLANG clang DOC "path to clang")

For both of these, -D can be used to set the value without modifying the CMakeLists.txt file. For example:

cmake . -DLLVM_CONFIG=/usr/local/bin/llvm-config -DCC=/usr/local/bin/clang

See also https://github.com/tomhrr/dale/blob/master/doc/all.md#c-compiler. I'll see about updating the documentation for the FFI problem.

This is my cmake command that works (but I think the lib-ffi stuff has to be configure like described above in order to work)

cmake ../dale -DLLVM_CONFIG=/usr/local/opt/llvm@14/bin/llvm-config -DCC=/usr/local/opt/llvm@14/bin/clang
