我正在尝试配置 GCC 4.7.2，但它失败了configure: error: Unable to find a usable PPL

我查看了GCC 先决条件页面，但没有在任何地方提及 PPL。

我正在使用CLooG 0.17.0，它使用ISL，因此不再需要 PPL （据我所知）

GCC 中对 PPL 是否还有其他要求，这意味着我仍然需要 PPL，还是我的configure行中缺少一些标志？

我将以下选项传递给configure：

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

为了完整起见，我的完整配置行如下：

./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：

为了尝试取得进展，我决定将PPL添加到我的安装列表中，并添加--with-ppl=$PREFIX到我的配置行中。

配置仍然失败configure: error: Unable to find a usable PPL

看来这是configure脚本中的一个错误：如果配置失败PPL_MINOR_VERSION < 11

使用最新版本PPL_MINOR_VERSION=0（和PPL_MAJOR_VERSION=1）

GCC Prerequisites 页面抢先一步，展示了 GCC 4.8 的先决条件。

GCC 4.7.2 仍然使用 PPL 而不是 ISL，如下--with-isl=PATH所示configure：

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-build-libsubdir=DIR  Directory where to find libraries for build system
  --with-mpc=PATH         specify prefix directory for installed MPC package.
                          Equivalent to --with-mpc-include=PATH/include plus
                          --with-mpc-lib=PATH/lib
  --with-mpc-include=PATH specify directory for installed MPC include files
  --with-mpc-lib=PATH     specify directory for the installed MPC library
  --with-mpfr-dir=PATH    this option has been REMOVED
  --with-mpfr=PATH        specify prefix directory for installed MPFR package.
                          Equivalent to --with-mpfr-include=PATH/include plus
                          --with-mpfr-lib=PATH/lib
  --with-mpfr-include=PATH
                          specify directory for installed MPFR include files
  --with-mpfr-lib=PATH    specify directory for the installed MPFR library
  --with-gmp-dir=PATH     this option has been REMOVED
  --with-gmp=PATH         specify prefix directory for the installed GMP
                          package. Equivalent to
                          --with-gmp-include=PATH/include plus
                          --with-gmp-lib=PATH/lib
  --with-gmp-include=PATH specify directory for installed GMP include files
  --with-gmp-lib=PATH     specify directory for the installed GMP library
  --with-host-libstdcxx=L use linker arguments L to link with libstdc++ when
                          linking with PPL
  --with-stage1-ldflags=FLAGS
                          linker flags for stage1
  --with-stage1-libs=LIBS libraries for stage1
  --with-boot-libs=LIBS   libraries for stage2 and later
  --with-boot-ldflags=FLAGS
                          linker flags for stage2 and later
  --with-ppl=PATH         specify prefix directory for the installed PPL
                          package. Equivalent to
                          --with-ppl-include=PATH/include plus
                          --with-ppl-lib=PATH/lib
  --with-ppl-include=PATH specify directory for installed PPL include files
  --with-ppl-lib=PATH     specify directory for the installed PPL library
  --with-cloog=PATH       Specify prefix directory for the installed CLooG-PPL
                          package. Equivalent to
                          --with-cloog-include=PATH/include plus
                          --with-cloog-lib=PATH/lib
  --with-cloog-include=PATH
                          Specify directory for installed CLooG include files
  --with-cloog-lib=PATH   Specify the directory for the installed CLooG
                          library
  --with-build-sysroot=SYSROOT
                          use sysroot as the system root during the build
  --with-debug-prefix-map='A=B C=D ...'
                          map A to B, C to D ... in debug information
  --with-build-config='NAME NAME2...'
                          use config/NAME.mk build configuration
  --with-build-time-tools=PATH
                          use given path to find target tools during the build

不幸的是，他们不维护 4.8 之前版本的先决条件页面。
