29 hoursfix(build): Resolve clean build failure from generated timeline headerskal
When starting from a clean tree (where `src/generated/` does not exist), the build would fail with a "file not found" error for `generated/timeline.h`. This was due to an incorrect dependency graph where `gpu.cc` was compiled before its required header was generated. This commit fixes the issue by making the dependency explicit: - Modified `tools/seq_compiler.py` to explicitly generate `timeline.h` alongside `timeline.cc`. - Updated `cmake/DemoCodegen.cmake` to declare both files as `OUTPUT`s of the timeline compilation step. - Added a direct dependency from the `gpu` library target to the `generate_timeline` custom target in `cmake/DemoLibraries.cmake`. - Refactored the generated file paths in `DemoCodegen.cmake` into a single `GENERATED_CODE` variable for improved clarity and future-proofing.
30 hoursrefactor(codegen): Use gpu_init helper in seq_compiler.pyskal
Refactors the timeline code generator (`tools/seq_compiler.py`) to use the `gpu_init_color_attachment` helper function from `src/gpu/gpu.h`. This change removes platform-specific `#if !defined(DEMO_CROSS_COMPILE_WIN32)` directives from the generated C++ files (`timeline.cc`, `test_timeline.cc`) and centralizes the platform-aware initialization logic within the existing helper function. The generated code is now cleaner and easier to maintain. Both native macOS and Windows cross-compilation builds are confirmed to be successful.
30 hoursfix(build): Resolve Windows cross-compilation failuresskal
This commit fixes several issues that caused the Windows cross-compilation build (`scripts/build_win.sh`) to fail. The root causes were platform-specific API differences in the wgpu-native library and incorrect dependency tracking in the CMake build system for generated code. Changes: - **`tools/seq_compiler.py`**: The timeline generator now wraps `depthSlice` assignments in `#if !defined(DEMO_CROSS_COMPILE_WIN32)` directives to handle API differences in `WGPURenderPassColorAttachment`. - **`src/gpu/gpu.h`**: The `gpu_init_color_attachment` helper is now platform-aware, using a preprocessor guard for the `depthSlice` member. - **`src/effects/*.cc`**: All effects are updated to use the new platform-aware helper or have explicit guards for `depthSlice`. Also, replaced `WGPUTexelCopyTextureInfo` with the cross-platform alias `GpuTextureCopyInfo` in `rotating_cube_effect.cc`. - **`cmake`**: Added `tools/seq_compiler.py` as an explicit dependency to the `generate_timeline` and `generate_test_demo_timeline` custom commands. This ensures that changes to the generator script correctly trigger a rebuild of the generated C++ files. - **`scripts/build_win.sh`**: Removed the erroneous attempt to build the `seq_compiler.py` script as a native executable. With these changes, the Windows cross-compilation build now completes successfully.
