Mac OS 10.5.7 で GCC をクロスコンパイルしようとしています。GMP、MPFR、および MPC をインストールした後、次のコマンドを使用して GCC を構成しました。
../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
このエラーが発生しました:
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.
GCC が GMP、MPFR、および MPC のヘッダーを検出できたのに、ライブラリを検出できなかったのはなぜですか?
