我很难将boost库交叉编译到arm平台
我从http://sourceforge.net/projects/boost/files/boost/。我试过1.55、1.54和1.49版本，它们的表现都一样。
拆包后，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目录以及其他目录。）。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，比如：
`"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 ;
在再次运行交叉编译后，我得到了很多

我真的不知道现在该怎么办。我在谷歌上搜索了几个小时，但没有结果。我试过用b2代替bjam，但没有什么变化。我还尝试了一个不同的arm交叉编译程序-Xilinx EABI Sourcery CodeBench Lite 2012.03-83（gcc 4.6.3），它似乎产生的错误较少，但仍然有很多语法，而且不存在类似文件或目录的错误。我如何才能在手臂平台上获得提升？
-
error: 'sys/mman.h: No such file or directory-编译器找不到标头"sys/man.h"，因为包含路径不正确或您的系统不包含此文件。 -
您为嵌入式系统进行编译，例如arm non-eabi（用于裸金属）。boost.conf不支持此ABI。要禁用内置的boost.conf和boost.coroutine（取决于boost.context），您必须调用：
b2 --without-context --without-coroutine
