Question

我有一个旧版本的boost 1.33.1。我想用一个自定义的gcc二进制文件来构建它，而不是默认的路径。我无法在网络上找到该网页，因此我粘贴了gcc-tools.jam表单tools/build/v1/gcc-tools.jam的第一部分。

  # compute directories for invoking GCC
  #
  # The gcc toolset can be user-configured using the following
  # variables:
  #
  # GCC_ROOT_DIRECTORY
  #       The directory in which GCC was installed. Defaults to
  #       unset. Usually, there is no need to set this variable at
  #       all. However, if G++ is not in the path it is usually
  #       sufficient to configure this one variable. More fine-grained
  #       configuration is available by setting the following:
  #
  # GCC_BIN_DIRECTORY
  #       the directory prefix used to find the gcc executables. Defaults to
  #       $(GCC_ROOT_DIRECTORY)/bin/, or "" if GCC_ROOT_DIRECTORY is
  #       not set.
  #
  # GCC_INCLUDE_DIRECTORY
  #       the directory in which to find system includes. Defaults to
  #       empty.
  #
  # GCC_STDLIB_DIRECTORY
  #       the directory in which to find the standard library
  #       objects associated with this build of gcc. Defaults to
  #       $(GCC_ROOT_DIRECTORY)/lib.
  #
  # GXX
  #       The name by which g++ is invoked. You can also use this in
  #       lieu of setting the <cxxflags> property to force options such
  #       as "-V3.0.4" into the g++ command line: "-sGXX=g++ -V3.0.4".
  #
  # GCC
  #       Similar to GXX, the name by which gcc is invoked for "C"
  #       language targets.

  # singleton variables...
  set-as-singleton GCC_ROOT_DIRECTORY GCC_BIN_DIRECTORY GCC_INCLUDE_DIRECTORY GCC_STDLIB_DIRECTORY ;

  flags gcc GCC_BIN_DIRECTORY : $(GCC_BIN_DIRECTORY) ;
  flags gcc GCC_INCLUDE_DIRECTORY : $(GCC_INCLUDE_DIRECTORY) ;
  flags gcc GCC_STDLIB_DIRECTORY : $(GCC_STDLIB_DIRECTORY) ;

  GCC_BIN_DIRECTORY ?= $(GCC_ROOT_DIRECTORY)$(SLASH)bin ;
  GCC_BIN_DIRECTORY ?= "" ; # Don't clobber tool names if GCC_ROOT_DIRECTORY not set
  GCC_STDLIB_DIRECTORY ?= $(GCC_ROOT_DIRECTORY)$(SLASH)lib ;

  # Make sure this gets set "on" the target
  flags gcc GCC_BIN_DIR : $(GCC_BIN_DIRECTORY) ;

  flags gcc LINKFLAGS <runtime-link>static : -static ;
  flags gcc CFLAGS <debug-symbols>on : -g ;
  flags gcc LINKFLAGS <debug-symbols>on : -g ;
  flags gcc CFLAGS <optimization>off : -O0 ;
  flags gcc CFLAGS <optimization>speed : -O3 ;

在这部分中，我可以使用注释部分中定义的变量将默认的gcc / g ++修改为我自己的。但是我不知道怎么做。例如，我写

 GCC_BIN_DIRECTORY=/opt/gcc-4.1.2/installed

但是这给了我这个错误：

 rule GCC_ROOT_DIRECTORY=/opt/gcc-4.1.2/installed unknown in module

那我怎么能这样做呢？

有脚本bjam或b2，请点击此处查看：http://www.boost.org/boost-build2/doc/html/bbv2/reference/tools.html#bbv2.reference.tools.compiler.gcc

并尝试：

./b2 root /usr/local/mygcc

应该使用提供的编译器

修改构建boost的默认编译器路径
