make: *** No rule to make target 'onnx2c'. Stop.

I'm trying to build onnx2c but have been stuck on the make part. I've installed protobuf via vcpkg and this is what I get when I try to build:

Using cmake -DCMAKE_BUILD_TYPE=Release .. gave me these errors:

-- Compiling and running to test HAVE_STD_REGEX -- Performing Test HAVE_STD_REGEX -- failed to compile -- Compiling and running to test HAVE_GNU_POSIX_REGEX -- Performing Test HAVE_GNU_POSIX_REGEX -- failed to compile -- Compiling and running to test HAVE_POSIX_REGEX -- Performing Test HAVE_POSIX_REGEX -- failed to compile CMake Error at benchmark/CMakeLists.txt:308 (message):

So I changed it to this:

PS C:\Users\Haris\Desktop\python\onnx2x\onnx2c\build> cmake -DCMAKE_CROSSCOMPILING=1 -DRUN_HAVE_STD_REGEX=0 -DRUN_HAVE_POSIX_REGEX=0 .. -- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19045. -- git version: v1.7.0-10-g77d1e74d normalized to 1.7.0.10 -- Version: 1.7.0.10 -- Performing Test HAVE_STD_REGEX -- success -- Performing Test HAVE_GNU_POSIX_REGEX -- failed to compile -- Performing Test HAVE_POSIX_REGEX -- success -- Compiling and running to test HAVE_STEADY_CLOCK -- Performing Test HAVE_STEADY_CLOCK -- failed to compile -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - not found -- Found Threads: TRUE -- Configuring done (3.0s) -- Generating done (3.0s) -- Build files have been written to: C:/Users/Haris/Desktop/python/onnx2x/onnx2c/build

And then:

PS C:\Users\Haris\Desktop\python\onnx2x\onnx2c\build> make onnx2c make: *** No rule to make target 'onnx2c'. Stop.

protoc --version returns libprotoc 3.21.12

Any ideas or anything else I should add?

thanks

As far as I know, this is the first attempt to build onnx2c on Windows. So a bumpy ride is expected.

In stead of running make, would a build with CMake work? cmake --build . --config Release?

I get this with your suggestion:

1>Checking Build System -- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19045. -- git version: v1.7.0-10-g77d1e74d normalized to 1.7.0.10 -- Version: 1.7.0.10 -- Performing Test HAVE_STD_REGEX -- success -- Performing Test HAVE_GNU_POSIX_REGEX -- failed to compile -- Performing Test HAVE_POSIX_REGEX -- success -- Performing Test HAVE_STEADY_CLOCK -- failed to compile -- Configuring done (1.4s) -- Generating done (17.7s) -- Build files have been written to: C:/Users/Haris/Desktop/python/onnx2x/onnx2c/build cl : command line error D8021: invalid numeric argument '/Werror' [C:\Users\Haris\Desktop\python\onnx2x\onnx2c\build\cm ake_timestamp\timestamp.vcxproj]

I'll keep trying and post a possible solution here although I guess I'll probably just use a linux systrem.

thanks

Right... Seems some gcc/clang command line options are hard-coded into the CMake files. A fix for these is of course welcome, but there might be quite a lot of spots to fix. Linux is for sure the easier route to take for now.

Some new Windows build related discussion in #49, closing this in favour of moving the discussion there.
