GCC 找不到 GMP、MPFR 和 MPC 库

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

我收到此错误：

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？

I am trying to cross-compile GCC on Mac OS 10.5.7. I used this command to configure GCC after installing GMP, MPFR, and MPC:

../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

I got this error:

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

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.

Why could GCC find the headers for GMP, MPFR, and MPC but not the libraries?

我怀疑问题可能在于，当您尝试构建 64 位编译器时，这些库适用于 32 位，反之亦然。

我最近能够在 MacOS X 10.6.4 上构建 GCC 4.5.1，但我自己构建并安装了 GMP、MPFR 和 MPC 库 - 在 /usr/gnu64 （一个非标准位置，我用于为自己的利益而安装的东西）。我还使用了配置选项：

CC='gcc -m64'

强制进行 64 位构建。我在 Linux 上遇到了类似的问题（加上 opt-functions.awk 中的正则表达式的问题 - 使用左大括号前面的两个反斜杠可以轻松修复），并发现自从我构建以来 MPFR 和 MPC 库有了更新MacOS X：

GMP 5.0.1（而不是 4.2.4）
MPC 0.8.2（而不是 0.8.1）
MPFR 3.0.0（而不是 2.4.2）

自从我写这篇文章以来，我稍微改变了我的方法。我现在所做的记录在在 Mac 上安装 GNU GCC 中。基本上，我获取了 GMP、MPC、MPFR 的当前版本，并将它们的源代码放入 GCC 源目录中，然后让 GCC 自己编译库。这使得 GCC 负责定位库。

I suspect that the problem may be that the libraries are for 32-bit when you are attempting to build a 64-bit compiler, or vice versa.

I was able to build GCC 4.5.1 on MacOS X 10.6.4 recently, but I built and installed the GMP, MPFR and MPC libraries myself - in /usr/gnu64 (a non-standard location that I use for stuff that I install for my own benefit). I also used the configuration option:

CC='gcc -m64'

to force a 64-bit build. I had similar problems on Linux (plus a problem with a regex in opt-functions.awk - easily fixed with two back-slashes in front of an open brace) and found that there were updates to the MPFR and MPC libraries since I built on MacOS X:

GMP 5.0.1 (instead of 4.2.4)
MPC 0.8.2 (instead of 0.8.1)
MPFR 3.0.0 (instead of 2.4.2)

Since I wrote this, I've changed my methodology somewhat. What I now do is documented in Install GNU GCC on Mac. Basically, I get the current versions of GMP, MPC, MPFR and put their source code into the GCC source directory, and let GCC compile the libraries for itself. This makes GCC deal with locating the libraries.

你应该使用

--with-gmp=/usr/local/include \
    --with-mpfr=/usr/local/include --with-mpc=/usr/local/include

而不是

--with-gmp=/usr/local \
    --with-mpfr=/usr/local --with-mpc=/usr/local

You should use

--with-gmp=/usr/local/include \
    --with-mpfr=/usr/local/include --with-mpc=/usr/local/include

instead of

--with-gmp=/usr/local \
    --with-mpfr=/usr/local --with-mpc=/usr/local

我尝试在 OX 10.6.6 上编译 gcc-4.6.0 时遇到同样的问题。我正在使用 gmp-4.3.2 ；使用 gmp-5.0.1 代替，配置脚本似乎正确猜测“CC=gcc -std=gnu99 CFLAGS=-O2 -pedantic -m64 -mtune=core2 -march=core2”，并将其传递给 mpfr (3.0.1)。 1) 和 mpc (0.9) ，因此使用这些或更新版本的任何人都不会收到此错误。

我建议通过从其网站下载 gmp、mpfr 和 mpc 来安装它们。然后运行 ./configure （在下载文件的文件夹中）和 sudo make install。

GCC 应该可以在 Mac OSX（山狮）上编译。

请注意，mpc 取决于 mpfr 和 gmp。

我用它在 Mac OSX 上编译 pinion 内核。

安装了 mac ports mpfr、libmpc 和 gmp 后，我能够将其添加到配置脚本中：

--with-mpc=/opt/local/var/macports/software/libmpc/0.8.2_0/opt/local
--with-gmp=/opt/local/var/macports/software/gmp/5.0.1_0/opt/local
--with-mpfr=/opt/local/var/macports/software/mpfr/3.0.0-p8_0/opt/local

这是编译 ti msp430 工具链。

With mac ports mpfr, libmpc and gmp installed, I was able to tack this on the configure script:

--with-mpc=/opt/local/var/macports/software/libmpc/0.8.2_0/opt/local
--with-gmp=/opt/local/var/macports/software/gmp/5.0.1_0/opt/local
--with-mpfr=/opt/local/var/macports/software/mpfr/3.0.0-p8_0/opt/local

This was to compile a ti msp430 toolchain.
