I compiled the gcc v4.9.2 under platform mips64el. the error occurred as
mentioned.
I read the bug 59575 and ths solution. but it's for platform ARM. Who can help
me to fix it under platform mips64el? Thanks very much.
I configured as follows:
./configure --prefix=/usr --enable-shared --enable-threads=posix
--enable-__cxa_atexit --enable-clocale=gnu --disable-multilib
--with-system-zlib --enable-languages=c,c++ --with-abi=64
--disable-fixed-point --without-ppl --without-cloog --disable-checking
--disable-dssi --host=mips64el-neokylin-linux --build=mips64el-neokylin-linux
--target=mips64el-neokylin-linux
