我正在尝试在 Mac OS 10.5.7 上交叉编译 GCC。我在安装 GMP、MPFR 和 MPC 后使用此命令配置 GCC:
../gcc-4.5.0/configure --target=$i586-elf --prefix=/usr/local/cross \
--disable-nls \
--enable-languages=c,c++,fortran,java,objc,obj-c++,treelang,ada \
--without-headers --with-libiconv-prefix=/opt/local --with-gmp=/usr/local \
--with-mpfr=/usr/local --with-mpc=/usr/local
我收到了这个错误:
checking for the correct version of gmp.h... buggy but acceptable
checking for the correct version of mpfr.h... yes
checking for the correct version of mpc.h... yes
checking for the correct version of the gmp/mpfr/mpc libraries... no
configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations. Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also
http://gcc.gnu.org/install/prerequisites.html for additional info. If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files. They may be located in separate packages.
为什么 GCC 可以找到 GMP、MPFR 和 MPC 的标头,但找不到库?
