我无法使用自制软件安装 gcc48。安装失败（从配置输出的最后几行开始）：

我确实安装了isl。

: brew info isl

GCC 对 ISL 版本有严格的要求。目前 4.8 分支和主干 (4.9) 都需要 ISL 0.10 或 0.11。Homebrew 已将 ISL 暂时恢复到 0.11.2，所以现在应该没问题。

这不仅限于 Homebrew。如果 clog-0.18.0 使用 isl-0.11.1 的捆绑子包，则配置脚本有问题。该VERSION字符串未被正确替换，并"UNKNOWN"在isl_version()函数调用中设置为 - gcc 配置脚本正在测试的值。

您可能必须先构建（或安装）ISL，然后添加--with-isl-prefix=$SOME_DIR到 clog 配置选项，因此它使用外部 ISL 安装。我最近从源代码为 AVR 构建了 gcc-4.8.1，并使用了：

## isl-0.11.1 @ ftp://gcc.gnu.org/pub/gcc/infrastructure/

> ../configure --prefix=$CROSSDIR --with-gmp-prefix=$CROSSDIR
> make [check]; make install; rehash

and now build cloog-0.18.0 with the installed 'system' ISL:

> ../configure --prefix=$CROSSDIR --with-isl-prefix=$CROSSDIR \
--with-gmp-prefix=$CROSSDIR
> make [check]; make install; rehash

这还需要--with-isl=$CROSSDIR在 gcc 配置选项中添加：
