macOS build #2

Closed mvmn closed 2 months ago

mvmn commented 4 months ago

Any plans for making a macOS build instructions?

mvmn commented 3 months ago

P.S. I've tried to build on macOS, but I get errors with regard to libusb. I have libusb installed via Homebrew in /Users/mvmn/homebrew/Cellar/libusb/1.0.27

I've tried to compile libfobos with these additions to CMakeLists.txt

Can anyone help me with this?

I was able to get libfobos to build on the Mac by compiling with gcc instead of clang. You need to install gcc with homebrew, then set the C++ compiler when running cmake and then again when running make:

cmake -D CMAKE_CXX_COMPILER=/opt/homebrew/bin/g++-14 .. make CXX=/opt/homebrew/bin/g++-14

That should get you most of the way there. I think there was a problem in one of the Homebrew modules that caused the build to fail once I got to this point, plus I had to manually edit CMakeLists.txt to change the version of C from c99 to gnu17 and to fix a broken import in fobos/fobos.c where it couldn’t find libusb-1.0/libusb.h, but pointing to just libusb.h worked fine.

I have gcc, I've tried

cmake .. -DCMAKE_CXX_COMPILER=$(which g++-14)
make CXX=$(which g++-14)

but to no avail - exactly the same errors occur

thereisnocat commented 2 months ago

If it’s still throwing the error mentioning clang, then it’s not honoring the -D; maybe try that before the ..

mvmn commented 2 months ago

Seems like I have a wrong gcc

> gcc -v
Apple clang version 15.0.0 (clang-1500.3.9.4)
mvmn commented 2 months ago

Ok, seem this did some change

cmake -DCMAKE_C_COMPILER=$(which gcc) -DCMAKE_CXX_COMPILER=$(which g++-14) ..

even though in logs it still says it's CLang

But in the end I still have same errors

P.S. Installing gcc via Homebrew - seems the one I've been using is macOS bundled

thereisnocat commented 2 months ago

You have to specify gcc-version, like gcc-14, because Apple has gcc as an alias for clang.

@thereisnocat thanks a ton, I was able to build it all successfully using same steps as you mentioned.

Just in case, here are the steps in detail:

Resolved by using Homebrew gcc
