crosstool and uClibc

["Yann E. MORIN" <yann dot morin dot 1998 at anciens dot enib dot fr>]

Hello!

I'm working on making an armv5b-xscale-linux-gnu uClibc-based toolchain with
gcc-3.4.3. I based my work on the uClibc patch in contrib. The crtosstool
version is something after 0.35, that is named 0.36, but isn't odfficialy
released [0]

I stumbled on the following problem while building final gcc (last few lines
in [4]):

checking for library containing strerror... configure: error: Link tests are
not allowed after GCC_NO_EXECUTABLES.
make: *** [configure-target-libiberty] Error 1

What I found so far is [1] stating problems when the uClibc was configured
for a CPU lacking an FPU. Alas, I can't do without that, as my ARM indeed
has no FPU.

But in [2], they state crosgcc might have a fix (hey, crossgcc == crosstool?)
so I searched in the archives, but didn't find anything usefull except
[3] that is not really specific to uClibc...

If anyone has some idea, that would really be appreciated.

Thanks a lot!
Yann E. MORIN.
