BR2_PACKAGE_LLVM_RTTI is a sub-option of llvm, so it somehow means that llvm should be a dependency of mesa3d, which your patch does not add. But we already have a conditional dependency on llvm, so this nex rtti option should be a sub-condition of BR2_PACKAGE_MESA3D_LLVM? Regards, Yann E.

I know. But how does it make sense to add BR2_PACKAGE_LLVM_RTTI without a dependency on llvm? And note that mesa3d does not use the fact that llvm is enabled, to enable its llvm support; one has to explicitly request it with BR2_PACKAGE_MESA3D_LLVM. > > But we already have a conditional dependency on llvm, so this nex rtti > > option should be a sub-condition of BR2_PACKAGE_MESA3D_LLVM? > Setting -Dcpp_rtti=false when llvm isn't used is harmless, it seemed clearer > to just have the single independent conditional for BR2_PACKAGE_LLVM_RTTI. If you have a configuration with: BR2_PACKAGE_LLVM=y BR2_PACKAGE_LLVM_RTTI=y BR2_PACKAGE_MESA3D=y # BR2_PACKAGE_MESA3D_LLVM is unset Then llvm support is not built in mesa3d, yet your code would cause us to pass -Dcpp_rtti=true, which does not seem to make sense. So, I think we want that to move to the existing condition, like so: diff --git a/package/mesa3d/mesa3d.mk b/package/mesa3d/mesa3d.mk index 96520e2efd..980faced31 100644 --- a/package/mesa3d/mesa3d.mk +++ b/package/mesa3d/mesa3d.mk @@ -48,6 +48,11 @@ ifeq ($(BR2_PACKAGE_MESA3D_LLVM),y) MESA3D_DEPENDENCIES += host-llvm llvm MESA3D_MESON_EXTRA_BINARIES += llvm-config='$(STAGING_DIR)/usr/bin/llvm-config' MESA3D_CONF_OPTS += -Dllvm=enabled +ifeq ($(BR2_PACKAGE_LLVM_RTTI),y) +MESA3D_CONF_OPTS += -Dcpp_rtti=true +else +MESA3D_CONF_OPTS += -Dcpp_rtti=false +endif else # Avoid automatic search of llvm-config MESA3D_CONF_OPTS += -Dllvm=disabled Regards, Yann E.

I think I did it this way in case llvm gets pulled in as a transient dependency down the line. I mean -Dcpp_rtti=true is still technically accurate when BR2_PACKAGE_LLVM_RTTI=y even if BR2_PACKAGE_MESA3D_LLVM isn't set, it's just unused internally by mesa3d in that case I think. Having it separate from BR2_PACKAGE_MESA3D_LLVM seems to make things less likely to break in the event of llvm getting pulled in as a transient dependency in the future. > > So, I think we want that to move to the existing condition, like so: > > diff --git a/package/mesa3d/mesa3d.mk b/package/mesa3d/mesa3d.mk > index 96520e2efd..980faced31 100644 > --- a/package/mesa3d/mesa3d.mk > +++ b/package/mesa3d/mesa3d.mk > @@ -48,6 +48,11 @@ ifeq ($(BR2_PACKAGE_MESA3D_LLVM),y) > MESA3D_DEPENDENCIES += host-llvm llvm > MESA3D_MESON_EXTRA_BINARIES += llvm-config='$(STAGING_DIR)/usr/bin/llvm-config' > MESA3D_CONF_OPTS += -Dllvm=enabled > +ifeq ($(BR2_PACKAGE_LLVM_RTTI),y) > +MESA3D_CONF_OPTS += -Dcpp_rtti=true > +else > +MESA3D_CONF_OPTS += -Dcpp_rtti=false > +endif > else > # Avoid automatic search of llvm-config > MESA3D_CONF_OPTS += -Dllvm=disabled > > Regards, > Yann E.
