使用 Boost.Log 构建 Boost“错误：目标 { simple_event_log.mc. } 没有类型”

Question

我正在尝试构建 Boost.Log ( http://boost-log.sourceforge.net/libs/log/doc/html/index.html )。我将其添加到我的 boost 源中并执行了我常用的 boost 构建命令。

b2 --build-dir="D:\boost\1.51.0\boost" toolset=gcc variant=release link=static threading=multi  runtime-link=static --build-type=complete

但什么也没发生，我最终收到了这个：

您能否解释一下这是什么意思或者我如何才能看到更多错误信息？你是如何构建 Boost.Log 的？

Answer 1

问题的答案可以在这里找到：

其次，在某些时候，该库将需要消息编译器工具 (mc.exe)，而该工具在 MinGW、Cygwin 和 MSVC Express Edition 中不可用。您有两种选择来解决问题。对于 MinGW 和 Cygwin，您可以使用 Windmc.exe 工具，它与原始 mc.exe 类似。为此，您必须按照此票证中的说明修补 Boost.Build 文件（特别是 tools/build/v2/tools/mc.jam 文件）。之后，您将能够为 bjam 指定 mc-compiler=windmc 选项来构建库。

这是该补丁的链接。应用补丁并通过mc-compiler=windmc应该可以解决问题。

注意：另外，正如票证中的注释所述，您需要import mc ;在 后import fortran ;添加tools\build\v2\tools\gcc.jam。

应用补丁后，您的 mc.jam 文件应如下所示（确保您的文件如下所示）：

import common ;
import generators ;
import feature : feature get-values ;
import toolset : flags ;
import type ;
import rc ;

feature.feature mc-compiler : mc windmc : propagated ; 
feature.set-default mc-compiler : mc ; 

rule init ( )
{
}

type.register MC : mc ;


# Command line options
feature mc-input-encoding : ansi unicode : free ;
feature mc-output-encoding : unicode ansi : free ;
feature mc-set-customer-bit : no yes : free ;

flags mc.compile MCFLAGS <mc-input-encoding>ansi : -a ;
flags mc.compile MCFLAGS <mc-input-encoding>unicode : -u ;
flags mc.compile MCFLAGS <mc-output-encoding>ansi : -A ;
flags mc.compile MCFLAGS <mc-output-encoding>unicode : -U ;
flags mc.compile MCFLAGS <mc-set-customer-bit>no : ;
flags mc.compile MCFLAGS <mc-set-customer-bit>yes : -c ;

generators.register-standard mc.compile.mc : MC : H RC : <mc-compiler>mc ; 
generators.register-standard mc.compile.windmc : MC : H RC : <mc-compiler>windmc ;

actions compile.mc
{ 
    mc $(MCFLAGS) -h "$(<[1]:DW)" -r "$(<[2]:DW)" "$(>:W)" 
}

actions compile.windmc
{ 
    windmc $(MCFLAGS) -h "$(<[1]:DW)" -r "$(<[2]:DW)" "$(>:W)" 
} 

警告

boost-log\branches\bleeding-edge无法为我编译（gcc 4.7.1）。我使用它boost-log\trunk\boost-log成功构建了（构建于 2012 年 9 月 5 日）。
