A demo showing how to cross-compile Wolfram Library Link code using zig

Wolfram LibraryLink + Zig cross-compilation

A demo that shows how to cross-compile Wolfram Library Link code using zig.

Build

Tested in zig version:

$ zig version
0.12.0-dev.1127+32bc07767

Using build.zig

Build the demo_string libraries (for each supported platform) using the build.zig file:

$ zig build --summary all
Build Summary: 13/13 steps succeeded
install success
├─ install demo_string success
│  └─ zig build-lib demo_string Debug x86_64-windows cached 14ms MaxRSS:22M
├─ install demo_string cached
│  └─ zig build-lib demo_string Debug x86_64-windows (reused)
├─ install demo_string success
│  └─ zig build-lib demo_string Debug x86_64-linux cached 14ms MaxRSS:22M
├─ install demo_string cached
│  └─ zig build-lib demo_string Debug x86_64-linux (reused)
├─ install demo_string success
│  └─ zig build-lib demo_string Debug x86_64-macos cached 14ms MaxRSS:22M
├─ install demo_string cached
│  └─ zig build-lib demo_string Debug x86_64-macos (reused)
├─ install demo_string success
│  └─ zig build-lib demo_string Debug aarch64-macos cached 14ms MaxRSS:22M
└─ install demo_string cached
   └─ zig build-lib demo_string Debug aarch64-macos (reused)

This will build the library for all the supported platforms and install them on LibraryResources/.

Using ./build.wls

Build the demo_string libraries (for each supported platform) using the build.wls script (you need to provide the path to the directory containing the zig executable.):

Using a Makefile

Alternatively, build the library for each platform using the Makefile. For example, for Linux-x86-64:

$ make SYSTEM_ID=Linux-x86-64
zig build-lib ./src/demo_string.c -lc --name demo_string -dynamic -install_name libdemo_string.so -target x86_64-linux -I/Users/daniels/Library/CloudStorage/OneDrive-Personal/projects/zig-librarylink-crosscompilation/libs/LibraryLink/include -L/Applications/Mathematica.app/Contents/SystemFiles/Libraries/MacOSX-ARM64
mv *demo_string* ./LibraryResources/Linux-x86-64/
