Làm thế nào để biên dịch boost_thread với "-pthread" thay vì "-mthread"?

Question

Tôi có một hệ điều hành và biên dịch không có sẵn -mthread. Thow tôi có -pthread. Cách biên dịch boost_thread với -pthread thay vì -mthread?

My hiện biên dịch build log:

./b2 -j1 --with-thread link=static --prefix=./install-dir release threading=multi --builddir=./bu 
ild-dir install

Có thể bằng cách nào đó vá boost_thread để biên dịch trên nền tảng của tôi với trình biên dịch của tôi như vậy để làm boost_thread thint rằng nó sẽ được biên soạn với -pthread?

Nền tảng - cũ, sửa đổi hevily cigwin, gcc-4.2.1

Answer 1

Bạn có thể thử công cụ vá/xây dựng/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   } 
1037 

Nếu bạn cung cấp thêm thông tin, Tôi có thể cố gắng giúp bạn.

Answer 2

Bạn có thể vượt qua những lá cờ để trình biên dịch sử dụng các đối số CXXFLAGS, xem http://www.boost.org/build/doc/html/bbv2/reference/tools.html#bbv2.reference.tools.compiler.gcc Một số có thể giúp đây là: CXXFLAGS = -DPTHREADS CXXFLAGS = -DBOOST_THREAD_POSIX CXXFLAGS = -pthread CXXFLAGS = -DTHREAD
Bạn có thể phải thử nghiệm để nhận được chính xác kết quả bạn muốn, nhưng tôi sẽ bắt đầu bằng cách chạy lại lệnh của bạn dưới dạng

./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
