Hello, Ensure that your command using --disable-multilib & --disable-decimal-float options. So the whole command must be in this form : ../gcc-4.5.1/configure \ --target=$LFS_TGT --prefix=/tools \ --disable-nls --disable-shared --disable-multilib \ --disable-decimal-float --disable-threads \ --disable-libmudflap --disable-libssp \ --disable-libgomp --enable-languages=c \ --with-gmp-include=$(pwd)/gmp --with-gmp-lib=$(pwd)/gmp/.libs \ --without-ppl --without-cloog
Before using this command ,please use ../gcc-4.5.1/make clean , then use this command and then make ,make install ,& symlink command in the book. --Fady > Date: Sun, 5 Dec 2010 21:21:21 -0500 > Subject: error: fenv.h: No such file or directory > From: [email protected] > To: [email protected] > > Got this error well into the compilation of GCC-4.4.3 Pass 1.
