如何使用"-pthread"而不是"-mthread"编译boost_thread？

How to compile boost_thread with "-pthread" instead of "-mthread"?

本文关键字：boost 编译 thread -mthread 何使用 -pthread      更新时间：2023-10-16

我有一个操作系统，没有-mthread可用。我有-pthread。如何使用-pthread而不是-mthread编译 boost_thread ？

我当前的编译器构建日志：

可以以某种方式使用编译器在我的平台上编译我的平台上，以使boost_thread thint与-pthread进行编译？

平台 - 旧的，hevily修改的cigwin，GCC -4.2.1

您可以尝试修补工具/build/v2/tools/gcc.jam 

1017 rule setup-threading ( targets * : sources * : properties * )
1018 {
1019     local threading = [ feature.get-values threading : $(properties) ] ;
1020     if $(threading) = multi
1021     {
1022         local target = [ feature.get-values target-os : $(properties) ] ;
1023         local option ;
1024         local libs ;
1025 
1026         switch $(target)
1027         {
1028             case windows : option = -mthreads ;
1029             case cygwin  : option = -mthreads ;
1030             case solaris : option = -pthreads ; libs = rt ;
1031             case beos    : # No threading options.
1032             case *bsd    : option = -pthread ;  # There is no -lrt on BSD.
1033             case sgi     : # gcc on IRIX does not support multi-threading.
1034             case darwin  : # No threading options.
1035             case *       : option = -pthread ; libs = rt ;
1036         }

如果您提供了更多信息，我可以尝试为您提供帮助。

您可以使用CXXFLAGS参数将标志传递给编译器，请参见http://www.boost.org/build/doc/doc/html/bbv2/reference/reference/tools.html.s.html#bbv2。reference.tools.compiler.gcc有些可能会有所帮助的是：cxxflags = -dpthreads cxxflags = -dboost_thread_posix cxxflags = -pthread cxxflags = -dthread
您可能必须进行试验才能完全获得所需的结果，但是我将从将您的命令重新编写为

开始 
./b2 -j1 --with-thread link=static cxxflags=-DPTHREADS cxxflags=-DBOOST_THREAD_POSIX cxxflags=-pthread cxxflags=-DTHREAD --prefix=./install-dir release threading=multi --builddir=./build-dir install
