无法识别的命令行选项，同时编译boost for cygwin [英] unrecognized command line option while compiling boost for android on cygwin

问题描述

我试图通过以下文章

但是当我运行以下语句时

  bjam --without-python --without-serialization toolset = gcc-android4.4.3 link = static runtime-link = static target-os = linux --stagedir = android 
  

它开始编译，但由于以下错误而失败：

  cc1plus.exe：错误：无法识别的命令行选项-mthreads
  

我使用最新的cygwin和boost 1.48.0

如果有人可以给我一个提示删除此错误，我将感激。

更新：

我找到解决方案。 Boost认为cygwin有MingW gcc编译器，所以它添加了配置文件gcc.jam中的特殊选项。一旦我删除了它的选项就可以了。

解决方案

短

通过 target-os = android c $ c> b2

说明我面临同样的问题Boost 1.59

根据 boost / tools / build / src / tools / gcc.jam line 1024

 规则设置 - 线程（目标*：sources *：properties *）
 {
 local threading = [feature.get-values threading：$（properties）]; 
 if $（threading）= multi 
 {
 local target = [feature.get-values target-os：$（properties）]; 
 local option; 
 local libs; 
 
 switch $（target）
 {
 case android：＃没有线程选项，一切都在。 
 case windows：option = -mthreads; 
 case cygwin：option = -mthreads; 
 case solaris：option = -pthreads; libs = rt; 
 case beos：＃没有线程选项。 
 case haiku：option =; 
 case * bsd：option = -pthread; ＃在BSD上没有-lrt。 
 case sgi：＃gcc on IRIX不支持多线程。 
 case darwin：＃没有线程选项。 
 case *：option = -pthread; libs = rt; 
} 
 
如果$（选项）
 {
选项$（目标）+ = $（选项）; 
} 
如果$（libs）
 {
 FINDLIBS-SA on $（targets）+ = $（libs）; 
} 
} 
} 
  

c $ c> -mthreads 取决于 target-os param

I am trying to compile boost on cygwin with help of following article

But when I ran following statement

bjam --without-python --without-serialization toolset=gcc-android4.4.3 link=static runtime-link=static target-os=linux --stagedir=android

It started compilation but failed due to following error:

cc1plus.exe: error: unrecognized command line option "-mthreads"

I am using latest cygwin and boost 1.48.0

I would appreciate if anybody can give me a hint to remove this error.

Update:

I found solution. Boost assumed cygwin has MingW gcc compiler so it added that special option in configuation file "gcc.jam" Once I removed the option it ran OK.

解决方案

Short

Pass target-os=android to b2

Explanation

I faced with same issue for Boost 1.59

According boost/tools/build/src/tools/gcc.jam line 1024

rule setup-threading ( targets * : sources * : properties * )
{
    local threading = [ feature.get-values threading : $(properties) ] ;
    if $(threading) = multi
    {
        local target = [ feature.get-values target-os : $(properties) ] ;
        local option ;
        local libs ;

        switch $(target)
        {
            case android : # No threading options, everything is in already.
            case windows : option = -mthreads ;
            case cygwin  : option = -mthreads ;
            case solaris : option = -pthreads ; libs = rt ;
            case beos    : # No threading options.
            case haiku   : option = ;
            case *bsd    : option = -pthread ;  # There is no -lrt on BSD.
            case sgi     : # gcc on IRIX does not support multi-threading.
            case darwin  : # No threading options.
            case *       : option = -pthread ; libs = rt ;
        }

        if $(option)
        {
            OPTIONS on $(targets) += $(option) ;
        }
        if $(libs)
        {
            FINDLIBS-SA on $(targets) += $(libs) ;
        }
    }
}

As you can see -mthreads depends on target-os param
