Just wondering, does buildroot get tested as a cross-compiler
building native toolchain?
There is a similar bug posted, which I think refers to building
the foreign, native, compiler.
At least that is my own problem. ;)
In my case, gcc's configure is failing when it tries to test for
the presence of mpfr (which is present, and built) - - -
(No problem with gpm)
I have captured the configure command being run and the test file,
then ran them "by hand" with -v the best I can figure out at that point is:
The "canned" test routine is test compiled with the working
cross-compiler - and it can't find the mpf header file.
But all of the gcc command line options seem correct to my eye, and the
search paths that -v reports that gcc is using seem correct.
A true puzzle, not a show-stopper here, anytime by 2010.02 would be fine.
This is gcc-4.3.whatever targeting mipsel.

The BR2_PACKAGE_GCC_TARGET? No, that isn't commonly used. That doesn't
mean that it shouldn't work ofcourse.

Hmm, it worked for me last time I tried (some time this summer).

It would be good if you could add a bugreport to bugzilla so we don't
forget about it.

One more note while waiting for me to document this in a true bug-report.
I considered handling gpm and mpf as "patches" to gcc - -
Since gcc will configure and build them if it finds them in its source tree.
I made up a gcc tarball along those lines and tried it - -
Same result - cross-compiler builds, native-compiler fails to configure
while testing for mpf header files (two or three missing and/or renamed symbols).
As a reminder: this is gcc-4.3.x targeting MIPS (32-R2, 24Kc, hard-float).
gcc-4.4.x is hopeless for MIPS at the moment, implements an ABI change for MIPS,
mostly in how structures are packed.
