Bug 124254 – [3.4/build] USE flag "objc-gc" for sys-devel/gcc does not imply dependancy on dev-libs/libgc: missing gc.h header

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Rob Andrews 2006-02-27 05:42:06 UTC]

When building gcc (3.4.5) with USE flags 'objc' and 'objc-gc' for Objective C support, USE flag 'objc-gc' does not imply a dependancy on dev-libs/libgc (or boehm-gc). Hence the build fails when it cannot find header gc.h.

gcc-3.4.5 comes with boehm-gc bundled in ...

That's strange.

In which case, when enabling the garbage collector for objc (USE flag obj-gc), the gcc-objc build cannot find the gc.h header.

(Ok well my bag marked as dublicate, I should have posted here)

It seems that gcc 4.1 has the same issue.
