Building

[konsumer]

Hi, great work on the codegen.

I am trying to use it to generate native quickjs extension, and I'm having a lot of issues, and I think the problems are not related to emscripten at all.

I feel like I am in a kind of circular dependency-hell, and hoped you might be able to help.

# get code
git clone https://github.com/bellard/quickjs.git --depth 1
git clone https://github.com/raysan5/raylib.git --depth 1
git clone https://github.com/raysan5/raygui.git --depth 1
git clone https://github.com/exaequos/raylib-qjs.git --depth 1

# build deps
cd quickjs
make
cd ../raylib
cmake -B build
cmake --build build

# build raygui demos to test
cd ../raygui/projects/CMake
cmake -B build
cmake --build build
cd ../../..


# so far so good

# generate code, without emscripten
python3 raylib-qjs/src/raylib_qjs.py raylib-qjs/api/raylib_api.json raylib-qjs/api/rcamera_api.json raylib-qjs/api/raygui_api.json raylib-qjs/api/raymath_api.json | grep -vE emscripten.h > raylib_qjs.c

# build
clang -Lquickjs -Lraylib/build/raylib -lraylib -lquickjs -Iraylib/src -Iquickjs/ -Iraygui/src -shared -o raylib_qjs.so raylib_qjs.c

Then I get tons of errors like:

raylib_qjs.c:21539:16: error: call to undeclared function 'IsMaterialReady'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
 21539 |     bool ret = IsMaterialReady(arg0);
       |                ^
raylib_qjs.c:21539:16: note: did you mean 'js_IsMaterialReady'?
raylib_qjs.c:21532:16: note: 'js_IsMaterialReady' declared here
 21532 | static JSValue js_IsMaterialReady(JSContext *ctx, JSValueConst this_val, int argc, JSValueConst *argv)
       |                ^
 21533 | {
 21534 |     Material * argptr0 = (Material *)JS_GetOpaque2(ctx, argv[0], js_Material_class_id);
 21535 |         if (argptr0 == NULL) return JS_EXCEPTION;
 21536 |
 21537 |         Material arg0 = *argptr0;
 21538 |
 21539 |     bool ret = IsMaterialReady(arg0);

which makes me think I have a version-mismatch, so I try with a version closer to what I think you are using:

rm -rf raylib
git clone https://github.com/raysan5/raylib.git --depth 1 --branch 5.0

# rebuild raylib
cd raylib
cmake -B build
cmake --build build
cd ..

all good, now I have raylib@5.0

# build
clang -Lquickjs -Lraylib/build/raylib -lraylib -lquickjs -Iraylib/src -Iquickjs/ -Iraygui/src -shared -o raylib_qjs.so raylib_qjs.c

It compiles, but I get tons of linker warnings/errors like:

ld: warning: object file (raylib/build/raylib/libraylib.a[2](rcore.c.o)) was built for newer 'macOS' version (14.6) than being linked (14.0)

and

Undefined symbols for architecture arm64:
  "_CFArrayAppendValue", referenced from:
      __glfwInitJoysticksCocoa in libraylib.a[26](cocoa_joystick.m.o)
      _matchCallback in libraylib.a[26](cocoa_joystick.m.o)
  "_CFArrayCreateMutable", referenced from:

I have raylib (5.5) installed with brew, too, so I do this:

clang -Lquickjs -lquickjs -Iquickjs/ -Iraygui/src $(pkg-config --cflags --libs raylib) -shared -o raylib_qjs.so raylib_qjs.c

and I get

raylib_qjs.c:4:10: fatal error: 'rcamera.h' file not found
    4 | #include "rcamera.h"

So I think maybe I need to go back to raylib 5.5 (since that is version installed on my system) and codegen from that.

rm -rf raylib
git clone https://github.com/raysan5/raylib.git --depth 1

# rebuild raylib
cd raylib
cmake -B build
cmake --build build
cd ..

python3 raylib-qjs/src/raylib_qjs.py raylib-qjs/api/*.json | grep -vE emscripten.h > raylib_qjs.c

and I get param type not supported: Font

Since the script exits, and I want to see all the errors, I remove the exit(0)

param type not supported: Font
return type not supported: Font
param type not supported: Vector2 *
param type not supported: Rectangle *
param type not supported: Vector2 *
param type not supported: Color *
param type not supported: Color *
param type not supported: Vector3 *
param type not supported: Vector3 *

I tried to edit the codegen for these types, but I found it incredibly hard to follow. Do you have interest in supporting raylib 5.5? Is there something else I should do to get this to build? I tried to make my own quickjs-wrapper-generator a while ago, and got very overwhelmed, so I'd like to use yours, if possible.
