Dear Sir:
After failing to compile gcc3.4.0,I chang to gcc2.95.3 with binutils 2.10.1.
Building binutils is successful, and the gcc is almost successful.The error is as following, but I don't know where is "asm/unistd.h"is from. How to resovle it? Thanks.
configure gcc as:
../gcc-2.95.3/config --target=arm-linux --prefix=/home/lurj/board_tms5471/tools --without-headers --with-newlib --enable-languages=c
