Hi Yann,FLOAT_NOT_NEEDED -Dinhibit_libc -mlong-double-128 -I. -I. -I../.././gcc -I/home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc -I/home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc/. -I/home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc/../gcc -I/home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc/../include -I/home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc/../libdecnumber/dpd -I/home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc/../libdecnumber -DHAVE_CC_TLS -o decExcept.o -MT decExcept.o -MD -MP -MF decExcept.dep -c /home/baruch/download/crosstool-ng-ppc/.build/src/gcc-4.5.2/libgcc/../libdecnumber/decExcept.c
I'm trying to build a PowerPC e500 uClibc toolchain using crosstool-ng, and I'm consistently getting a "fatal error: fenv.h: No such file or directory" error at the "Installing static core C compiler" stage. I've selected gcc 4.5.2, binutils 2.21, and uClibc 0.9.31. My host toolchain is gcc 4.6.1 (prerelease), and binutils 2.21.51.20110523, on current Debian Wheezy (testing).
The full failed command line is as follows:
[ALL ] /home/baruch/download/crosstool-ng-ppc/.build/powerpc-e500v2-linux-uclibc/build/build-cc-core-static/./gcc/xgcc -B/home/baruch/download/crosstool-ng-ppc/.build/powerpc-e500v2-linux-uclibc/build/build-cc-core-static/./gcc/ -B/home/baruch/download/crosstool-ng-ppc/.build/powerpc-e500v2-linux-uclibc/build/gcc-core-static/powerpc-e500v2-linux-uclibc/bin/ -B/home/baruch/download/crosstool-ng-ppc/.build/powerpc-e500v2-linux-uclibc/build/gcc-core-static/powerpc-e500v2-linux-uclibc/lib/ -isystem /home/baruch/download/crosstool-ng-ppc/.build/powerpc-e500v2-linux-uclibc/build/gcc-core-static/powerpc-e500v2-linux-uclibc/include -isystem /home/baruch/download/crosstool-ng-ppc/.build/powerpc-e500v2-linux-uclibc/build/gcc-core-static/powerpc-e500v2-linux-uclibc/sys-include -g -Os -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DIN_LIBGCC2 -D__GCC_

My .config and uClibc.config are attached. I can also provide the full build log if this is necessary.
Thanks for a great tool.
You need to have UCLIBC_HAS_FENV=y set in uclibc .config now how you bend ct-ng to do it is upto you.
