Question: build script for C library that uses Premake instead of CMake?

[dylanxyz]

There's a library called nanovg which i want to port to Julia, it is self-contained with just a few files, but it uses the Premake build system instead of CMake. I searched for any mentions of building libraries with Premake within the BinaryBuilder docs but i could not find anything. I'm sorry if i've missed something. Is there a way to use Premake in the build script or i have to convert the premake file to a CMakeLists.txt file?

The sandbox environment that BinaryBuilder uses is based on Alpine Linux, which has premake available via its package manager, so you should be able to apk add premake inside the script part of your builder recipe.

@ararslan When running apk add premake i got the following error:

sandbox:${WORKSPACE}/srcdir # apk add premake

fetch https://dl-cdn.alpinelinux.org/alpine/v3.15/community/x86_64/APKINDEX.tar.gz

Running from the BinaryBuilder Wizard, with WSL (Debian).

Did you do an apk update first?

premake is only in edge, not v3.15. Try instead

sandbox:${WORKSPACE} # apk add premake --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing
fetch http://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz
fetch https://dl-cdn.alpinelinux.org/alpine/v3.15/main/x86_64/APKINDEX.tar.gz

@giordano Thanks, that solution works and i'm able to use premake with this script:

cd ${WORKSPACE}/srcdir

if [[ "${target}" == *-freebsd* ]]; then
    os=bsd
elif [[ "${target}" == *-mingw32* ]]; then
    os=windows
elif [[ "${target}" == *-linux* ]]; then
    os=linux
elif [[ "${target}" == *-apple-* ]]; then
    os=macosx
fi

apk add premake --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing

cd nanovg
premake5 --os=${os} gmake2

cd build
make -j${nproc} config=release_x${nbits} nanovg

mkdir $libdir
mkdir $includedir

mv *nanovg.${dlext}             ${libdir}/libnanovg.${dlext}
mv ../src/nanovg.h              ${includedir}/
mv ../src/nanovg_gl.h           ${includedir}/
mv ../src/nanovg_gl_utils.h     ${includedir}/

install_license ../LICENSE.txt

However, the project won't build because nanovg uses a few opengl types and functions, so the compiler complains to me about undefined types. How can i include opengl in this project, so the compiler won't be mad at me?

[dylanxyz]

Never mind, i figured out 🧐.

[ararslan]

Sounds like the issue is resolved so I'll close.
