GCC 4.7.2需要ppl？

Question

我想配置GCC 4.7.2，但它與configure: error: Unable to find a usable PPL

我看着在GCC prerequisites page和PPL沒有提及任何地方失敗。

我使用CLooG 0.17.0，它採用ISL，因此不再需要PPL（據我可以告訴）

是否有PPL在GCC，這意味着我仍然需要PPL一些其他的要求，或我是否從我的configure行中錯過了一些標誌？

我傳遞下列選項configure：

• --enable-cloog-backend=isl
• --with-cloog=$PREFIX
• --with-isl=$PREFIX
• --with-gmp=$PREFIX
• --with-mpfr=$PREFIX
• --with-mpc=$PREFIX

爲了完整起見，我完全configure行如下：

./configure --prefix=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 \ 
    --disable-multilib --enable-cloog-backend=isl \ 
    --with-mpc=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 \ 
    --with-mpfr=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 \ 
    --with-gmp=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 \ 
    --with-isl=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 \ 
    --with-cloog=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 \ 
    --build=x86_64-suse-linux --with-pkgversion='SIG build 11/27/2012' \ 
    --with-gxx-include-dir=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/c++/4.7.2 \ 
    --enable-version-specific-runtime-libs 

更新：

爲了儘量讓着進步，我決定加入PPL我的安裝目錄，並添加--with-ppl=$PREFIX到我的配置線。

配置還是失敗，configure: error: Unable to find a usable PPL

看來這是在configure腳本錯誤：如果PPL_MINOR_VERSION < 11

隨着PPL_MINOR_VERSION=0（和PPL_MAJOR_VERSION=1）的最新版本

GCC的先決條件頁面躍升配置失敗並展示了GCC 4.8的先決條件。

GCC 4.7.2仍然使用PPL而不是ISL，就證明了在configure輸出缺乏--with-isl=PATH：前4.8

這是不幸的，他們沒有維護版本先決條件頁。
