【问题描述】：
我很难将 boost 库交叉编译到 arm 平台。
我从 http://sourceforge.net/projects/boost/files/boost/ 获取资源。我试过版本。 1.55、1.54 和 1.49 它们的行为都相同。
解压后我使用./bootstrap.sh --prefix=/blah/arm-none-eabi。 （arm-none-eabi 目录包含交叉编译器 include 和 lib 目录，还有其他。）。接下来，我通过添加 using gcc : arm : arm-none-eabi-g++ ;（ARM EABI Sourcery CodeBench Lite 2013.05-23 交叉编译器，gcc 版本 4.7.3）来更新文件 tools/build/v2/user-config.jam。之后，我运行./bjam --prefix=/blah/arm-none-eabi/ toolset=gcc-arm。这给了我很多错误，例如：
`"arm-none-eabi-g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -pthread -DBOOST_ALL_NO_LIB=1 -DBOOST_THREAD_USE_LIB=1 -DNDEBUG -I"." -c -o "bin.v2/libs/wave/build/gcc-arm/release/link-static/threading-multi/wave_config_constant.o" "libs/wave/src/wave_config_constant.cpp"
...failed gcc.compile.c++ bin.v2/libs/wave/build/gcc-arm/release/link-static/threading-multi/wave_config_constant.o...
gcc.compile.c++ bin.v2/libs/wave/build/gcc-arm/release/link-static/threading-multi/cpplexer/re2clex/aq.o
arm-none-eabi-g++: error: unrecognized command line option '-pthread'`
我修改了文件$BOOST/tools/build/v2/tools/gcc.jam
-case * : option = -pthread ; libs = rt ;
+case * : option = -lpthread ; libs = rt ;
再次运行交叉编译后，我得到了很多

我现在真的不知道该怎么办。我已经在谷歌上搜索了几个小时，但没有结果。我尝试使用 b2 而不是 bjam - 没有任何改变。我还尝试了不同的 arm 交叉编译器 - Xilinx EABI Sourcery CodeBench Lite 2012.03-83 (gcc 4.6.3)，它似乎产生的错误更少，但仍然有很多语法，并且没有类似文件或目录的错误存在。如何在 arm 平台上获得提升？
【问题讨论】：
-
看起来您需要
-std=c++11编译器选项集（-pthread仅在此 AFAIK 中受支持）。您实际使用的是哪个 GCC 版本？实际上，我们正在自己构建最新的 GCC (4.8) ARM 跨工具链版本。 -
这个链接可能有帮助（它描述了使用 GCC 4.7 构建跨工具链，但 GCC 4.8 并没有真正的区别）：dev-jungle.blogspot.de/2013/09/…
-
感谢您的回答。我已将 -std=c++11 添加到 gcc.jam（例如
"arm-xilinx-eabi-g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -std=c++11 -pthread -DBOOST_ALL_NO_LIB=1 -DBOOST_THREAD_USE_LIB=1 -DNDEBUG -I"." -c -o "bin.v2/libs/wave/build/gcc-arm/release/link-static/threading-multi/token_ids.o" "libs/wave/src/token_ids.cpp"），但我仍然不断收到有关无法识别的选项“-pthread”的错误。您提供的链接使用配置，这不能与 boost 一起使用。可能还有其他想法吗？ -
-std=c++11没有被 GCC 4.7 完全实现（尤其不是所有的std::thread部分）。我发给你的链接描述了如何构建 GCC 工具链，它与 boost 构建过程本身没有任何关系。 -
好的，我现在明白了。我会试一试，然后告诉你！
