Hello,
I am experiencing the error below while building gcc 4.2.2 for the mips64vr-elf
target. I have confirmed the same happens with gcc-4.2-20080116.
Versioning:
binutils 2.18
newlib-1.16.0
GCC configured this way:
$ CFLAGS=-O2 $DEPACK_DIR/gcc-4.2.2/configure --target=mips64vrel-elf \
--prefix=$PREFIX_DIR --enable-languages=c,c++ --disable-__cxa_atexit \
--with-gnu-as --with-gnu-ld --with-newlib \
--with-gxx-include-dir=$PREFIX_DIR/mips64vrel-elf/include -v \
2>&1 | tee configure.log
With the same configuration and binutils/newlib, I succeeded building GCC
4.1.2.
I saved all log for configure and make. Please let me know if they may help.
Thanks in advance.
