Question

我無法安裝gcc48自制軟件。安裝失敗， （從配置輸出的最後幾行開始）：

我有安裝ISL。

: brew info isl 
isl: stable 0.12, HEAD

這不限於自制。如果cloog-0.18.0使用isl-0.11.1的捆綁子包，配置腳本有問題。 VERSION字符串未被正確替換，並在isl_version()函數調用中設置爲"UNKNOWN" - gcc configure腳本正在測試的值。

您可能必須先構建（或安裝）ISL，然後將--with-isl-prefix=$SOME_DIR添加到cloog配置選項，以便它使用外部ISL安裝。我內置的gcc-4.8.1 AVR最近從來源和使用：

## 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 

這也需要增加：--with-isl=$CROSSDIR到GCC配置選項。

海灣合作委員會對ISL版本實行了嚴格的要求。當時4.8分支和中繼（4.9）需要ISL 0.10或0.11。 Homebrew暫時將ISL恢復到0.11.2，所以現在應該沒問題。
