在android中编译boost时出错

我正在尝试根据this将boost 1.5安装到android中。

编译时,我收到错误。这是编译错误的一个片段:

我发现了这个我不理解的错误......

./boost/thread/pthread/thread_data.hpp:42: error: 'PAGE_SIZE' was not declared in this scope。它说PAGE_SIZE没有宣布,但我不知道这意味着什么。当我试图查看代码中的特定位置时,我没有找到PAGE_SIZE

这个问题有1.50提升,ndk-r8b。

感谢这个主题,我设法通过以下更改解决了这个问题:

file boost / thread / thread.hpp

// Fix for missing macro
#define PAGE_SIZE sysconf(_SC_PAGESIZE)

#include <boost/thread/pthread/thread_data.hpp>

请注意,自1.50提升以来我也需要更改它:

文件boost / libs / filesystem / src / operations.cpp

# ifdef BOOST_POSIX_API

    const fs::path dot_path(".");
    const fs::path dot_dot_path("..");
#   include <sys/types.h>
#   include <sys/stat.h>
#   if !defined(__APPLE__) && !defined(__OpenBSD__) && !defined(ANDROID)
#     include <sys/statvfs.h>
#     define BOOST_STATVFS statvfs
#     define BOOST_STATVFS_F_FRSIZE vfs.f_frsize
#   elif defined (ANDROID)
#     include <sys/vfs.h>
#     define BOOST_STATVFS statfs
#     define BOOST_STATVFS_F_FRSIZE static_cast<boost::uintmax_t>(vfs.f_bsize)
#   else
#     ifdef __OpenBSD__
#     include <sys/param.h>
#     endif
#     include <sys/mount.h>
#     define BOOST_STATVFS statfs
#     define BOOST_STATVFS_F_FRSIZE static_cast<boost::uintmax_t>(vfs.f_bsize)
#   endif

这样的编译错误通常首先查看预处理的输出来解决。尝试将-c替换为-E并将foo.o更改为foo.pp(或其他内容)并查看foo.pp文件中的错误(搜索set_stack_size })。

这是相关代码:

        void set_stack_size(std::size_t size) BOOST_NOEXCEPT {
          if (size==0) return;
          std::size_t page_size = getpagesize();
#ifdef PTHREAD_STACK_MIN
          if (size<PTHREAD_STACK_MIN) size=PTHREAD_STACK_MIN;
#endif
          size = ((size+page_size-1)/page_size)*page_size;

getpagesize()扩展为引用PAGE_SIZE的内容。我非常确定sysconf是获取页面大小的正确方法(tm),但是增强维护者可能有充分的理由使用getpagesize()。无论如何,您可以使用-DPAGE_SIZE=2048编译器参数或任何目标的页面大小来避开此特定错误。要么是这样,要么修改源代码以使用sysconf(_SC_PAGESIZE)
