Hi, I'm trying to write a clean script that build a complete crossgcc toolchain (binutils, gcc3.0.4, and glibc) from scratch. Bill's FAQ has been very helpful, but there are a lot of gotchas, especially for the powerpc. I've put my build script and documentation online at http://www.dimator.org/~dimator/work/crossgcc/ It seems to work for sh4, but for ppc405 (which lacks an FPU) I keep running into problems. My current problem is it can't find fenv_libc.h when building the final glibc. Here is the line that fails: /home2/dimator/opt//ppc405/bin/powerpc-linux-gcc ../sysdeps/powerpc/fclrexcpt.c -c -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g -mnew-mnemonics -Wa,-mppc -mpowerpc -Wno-uninitialized -D__NO_MATH_INLINES -D__LIBC_INTERNAL_MATH_INLINES -DNO_LONG_DOUBLE -D_Mlong_double_=double -I../include -I. -I/home2/dimator/3rdParty/crosstools/glibc-ppc405/math -I.. -I../libio -I/home2/dimator/3rdParty/crosstools/glibc-ppc405 -I../sysdeps/powerpc/elf -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/powerpc -I../sysdeps/unix/sysv/linux/powerpc -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix/powerpc -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/powerpc -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/powerpc/soft-fp -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic -nostdinc -isystem /home2/dimator/opt//ppc405/lib/gcc-lib/powerpc-linux/3.0.4/include -isystem /home2/dimator/opt//ppc405/powerpc-linux/include/ -D_LIBC_REENTRANT -include ../include/libc-symbols.h -I../soft-fp/ -o /home2/dimator/3rdParty/crosstools/glibc-ppc405/math/fclrexcpt.o ../sysdeps/powerpc/fclrexcpt.c:20:23: fenv_libc.h: No such file or directory ../sysdeps/powerpc/fclrexcpt.c: In function `__feclearexcept': ../sysdeps/powerpc/fclrexcpt.c:26: `fenv_union_t' undeclared (first use in this function) ../sysdeps/powerpc/fclrexcpt.c:26: (Each undeclared identifier is reported only once ../sysdeps/powerpc/fclrexcpt.c:26: for each function it appears in.) ../sysdeps/powerpc/fclrexcpt.c:26: parse error before "u" ../sysdeps/powerpc/fclrexcpt.c:29: `u' undeclared (first use in this function) ../sysdeps/powerpc/fclrexcpt.c:29: warning: implicit declaration of function `fegetenv_register' ../sysdeps/powerpc/fclrexcpt.c:32: `FPSCR_VX' undeclared (first use in this function) ../sysdeps/powerpc/fclrexcpt.c:32: `FE_ALL_INVALID' undeclared (first use in this function) ../sysdeps/powerpc/fclrexcpt.c:33: `FPSCR_STICKY_BITS' undeclared (first use in this function) ../sysdeps/powerpc/fclrexcpt.c:36: warning: implicit declaration of function `fesetenv_register' make[2]: *** [/home2/dimator/3rdParty/crosstools/glibc-ppc405/math/fclrexcpt.o] Error 1 make[2]: Leaving directory `/home2/dimator/home/dank/ixia/Software/Source/linux/3rdParty/crosstools/glibc-2.2.5/math' make[1]: *** [math/others] Error 2 make[1]: Leaving directory `/home2/dimator/home/dank/ixia/Software/Source/linux/3rdParty/crosstools/glibc-2.2.5' make: *** [all] Error 2 /home2/dimator/opt//ppc405/bin/powerpc-linux-gcc -v: Reading specs from /home2/dimator/opt//ppc405/lib/gcc-lib/powerpc-linux/3.0.4/specs Configured with: ../gcc-3.0.4/configure --target=powerpc-linux --build=i686-linux --program-prefix=powerpc-linux- --prefix=/home2/dimator/opt//ppc405 --without-headers --enable-languages=c --with-newlib --disable-shared --with-cpu=403 --without-fp Thread model: single gcc version 3.0.4 glibc's configure switches: ../glibc-2.2.5/configure --host=powerpc-linux --enable-add-ons=linuxthreads --with-headers=/home2/dimator/opt//ppc405/powerpc-linux/include/ --prefix=/home2/dimator/opt//ppc405 --with-cpu=403 --without-fp Can anyone see what I'm doing wrong?
