Created attachment 105566 [details] build: define no features as 0 Currently in cairo-gl.h there is: #if CAIRO_HAS_GL_SURFACE || CAIRO_HAS_GLESV2_SURFACE When building cairo with --disable-glesv2 then the compiler warns that CAIRO_HAS_GLESV2_SURFACE is not defined. If those warnings are treated as errors then the build just fails (ex: webkit) The attached patch ensure all stuffs under put in NO_FEATURES are defined as 0, even for features defaulted to "no". Because currently only features defaults to auto or yes are put into NO_FEATURES when disabled.
Whoever sets -Werror is doomed to live to suffer from it.
Oki np. (webkitEFL enables it but I can disable it manually) What about the first part of the patch: -CAIRO_FEATURE_HOOK_REGISTER(no,!no,!, +CAIRO_FEATURE_HOOK_REGISTER(no,*,!, ? to have all the disabled features in the commentaries ( i.e. "/*#undef $FEATURE */" ) So that it's not confusing why in cairo-features.h you can see /*#undef CAIRO_HAS_EGL_FUNCTIONS */ but not /*#undef CAIRO_HAS_GLESV2_SURFACE */ when configuring cairo with --disable-egl --disable-glesv2 Thx!
Ok I think that's fair.
