编译GCC4.1.2问题

在make gcc4.1.2的时候会有下面的错误

应该怎么解决的。现在一头雾水！

libmpfr-dev

回复 #1 fireice335 的帖子

没有找到mpfr库，gcc 4.0之后需要安装该库和gmp库，并在configure中使用--with-gmp=... --with-mpfr=...来指定路径。

另外，还可能需要环境变量 LD_LIBRARY_PATH 来指定动态库的位置。

如果你不用Fortran的话，指定--enable-languages=c（你想的语言），看情况不是mpfc的问题，如果是它的问题的话，configure不会过的。应该是代码中Fortran的问题
