我试图将boost 1.57从64位Debian测试交叉编译为32位Windows。
Boost有cross-compile page，这并没有多大帮助。例如，我不得不谷歌并弄清楚我需要明确禁用bzip2 -sNO_BZIP2=1和zlib什么都没有 - 它会自动禁用它（以前你必须指定-sNO_ZLIB=1，但它现在已经破产了。）
所以，经过一些试验和错误后，我来到了：

-j10用于10个并发作业，因为我有8个逻辑cpu核心。
address-model=32用于32位构建
binary-format=pe suggested是libs/context/src/asm/make_i386_sysv_elf_gas.S中构建失败的解决方法。
上述内容失败了：

此时我已经陷入困境，我不知道如何解决这个问题，谷歌似乎没有帮助。
答案 0 :(得分：2)
通过简单地禁用失败的库来实现它，我碰巧不需要它
./b2 -j10 --user-config=user-config.jam toolset=gcc-mingw address-model=32 binary-format=pe target-os=windows release --prefix=/usr/i686-w64-mingw32/local --without-python --without-wave --without-context --without-coroutine --without-mpi --without-test --without-graph --without-graph_parallel -sNO_BZIP2=1
实际上，一些已禁用的库可能没有失败，我只是查看了所有库的列表，并禁用了与我需要的库完全无关的库。
当然，这并没有解决将所有的增强库交叉编译到Windows的问题，知道如何正确地做到这一点会很好，但是现在我和＃39 ; m满足于此。
