cmd 1 : ./configure --disable-multilib --prefix=/usr/local --with-mpc=/usr/local --with-mpfr=/usr/local --with-gmp=/usr/local && make -j4 && sudo make install cmd 2 : ./configure --disable-multilib --prefix=/usr/local && make -j4 && sudo make install
after I installed mpfr mpc gmp , I use --with-mpc=/usr/local to set the path, but configure give me the error blew: checking for the correct version of gmp.h... yes 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 2.4.0+ 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. but I already installed mpfr mpc and gmp into /usr/local directory, ls show like blew: vi@linx:/usr/local$ ls etc games gmssl include intranet_security lib man sbin share src vi@linx:/usr/local$ ls include/ gmp.h libelf mpc.h mpf2mpfr.h mpfr.h vi@linx:/usr/local$ ls lib libelf.a libelf.so.0 libgmp.a libgmp.so libgmp.so.10.3.2 libmpc.la<http://libmpc.la> libmpc.so.3 libmpfr.a libmpfr.so libmpfr.so.6.0.2 pkgconfig python2.6 libelf.so libelf.so.0.8.12 libgmp.la<http://libgmp.la> libgmp.so.10 libmpc.a libmpc.so libmpc.so.3.1.0 libmpfr.la<http://libmpfr.la> libmpfr.so.6 ocaml python2.5 site_ruby vi@linx:/usr/local$ pwd /usr/local vi@linx:/usr/local$ then I try configure without set mpc,mpfr and gmp location by use cmd 2: ./configure --disable-multilib --prefix=/usr/local && make -j4 && sudo make install it gives me the right configure result and then I can run make to buid the gcc 7.3.0 I want to know the reason. and where is wrong? thank you very much, guys! My system is Debian 6, codename is squeeze.
