NetBSD verthandi.technoskunk.fur 5.2_STABLE NetBSD 5.2_STABLE (VERTHANDI) #18: Tue Jul 15 08:12:12 CDT 2014 sysop@verthandi.technoskunk.fur:/d0/build/netbsd-5/obj/i386/sys/arch/i386/compile/VERTHANDI i386
>Description:
Packages which require a version of GCC newer than that found in the
host OS set GCC_REQD+=X.Y. If version X.Y{.Z} of GCC is not installed,
"lang/gccXY" will be built as a dependency and the tools wrapper will
be generated to use that compiler.
If one has an existing installation of "lang/gccMN" such that M.N > X.Y,
the compiler-selection mechanism does not consider this compiler as
acceptable (does it consider it at all?) and proceeds to build the
earlier version as a dependency.
This is most evident on netbsd-5 systems which ship gcc 4.1.3 in the
"comp" set. Many packages require the features of gcc 4.4.x, 4.5.x, or
4.6.x to build properly and set GCC_REQD+=4.4, GCC_REQD+=4.5 or
GCC_REQD+=4.6, respectively, causing the corresponding "lang/gccXY" to
be built as a dependency.
Depending on the order in which packages are built, "lang/gcc46" may
be built before any of the other "lang/gccXY" versions which may be
the minimum required for other packages.
The resulting "lang/gcc46" package is not considered acceptable (at
all?) for subsequent packages which set "GCC_REQD+=4.4" or
"GCC_REQD+=4.5" causing the corresponding "lang/gcc44" or "lang/gcc45"
to be built.
A particular instance is "www/firefox" and "multimedia/libvpx".
"firefox" requires GCC 4.6 minimum on netbsd-5 while "multimedia/libvpx
requires GCC 4.4 minimum. If one preemptively installs "lang/gcc46"
"multimedia/libvpx" will still build "lang/gcc44".
>How-To-Repeat:
On NetBSD-5.* in particular, or any host platform without a suitable
version of GCC:
Install "lang/gcc46" (or later)
Build any package which sets "GCC_REQD+=4.4" or "GCC_REQD+=4.5" (etc).
Older version will be fetched, built and installed while newer version
is ignored.

State-Changed-Why:
Wontfix. I provided a patch to do this in tech-pkg at some point, but it was considered too much magic. consequent builds won't be identical. We should probably consider a more satisfactory solution such as a single OK pkgsrc toolchain which won't introduce too much magic.
