solaris - 编译64位gcc - elf类错误 [英] solaris - compile 64bit gcc - elf class error

问题描述

我正在solaris上安装gcc的现代版本。我编译gmp，mpfr和mpc，他们都是64位。当我尝试配置gcc如下我得到一个错误抱怨mpc，mpfr和gmp是错误的elf类。什么给了？

I'm installing a modern version of gcc on solaris. I compiled gmp, mpfr and mpc, they're all 64bit. When I try to configure gcc as follows I get an error complaining that mpc,mpfr and gmp are the wrong elf class. What gives?

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.

推荐答案

GCC不会被构建为64位二进制，而是32位。因此，您需要通过强制 configure ABI = 32 在32位模式下重建GMP，MPFR和MPC。

With the default configure line, GCC will not be built as a 64-bit binary, but as 32-bit. So, you need to rebuild GMP, MPFR and MPC in 32-bit mode, by forcing configure ABI=32.

或者，您可以使用 sparc64-sun-solarisX 构建三元组配置GCC。在这种情况下，GCC网站上有其他说明。

Alternatively, you can configure GCC with a sparc64-sun-solarisX build triplet. In that case, there are additional instructions on the GCC website.
