cmake找不到提升线程

Question

我想使用emscripten编译一些项目到js。该项目使用cmake作为构建工具。

这是我如何我打电话的cmake：

cmake -DEMSCRIPTEN=1 
-DCMAKE_TOOLCHAIN_FILE=~/Documents/emscripten/cmake/Platform/Emscripten_unix.cmake 
-DCMAKE_MODULE_PATH=~/Documents/emscripten/cmake 
-DCMAKE_BUILD_TYPE=Release 
-G "Unix Makefiles" 
-DRDK_BUILD_PYTHON_WRAPPERS= 
-DBOOST_INCLUDEDIR=~/Documents/boost_1_53_0/boost 
-DBOOST_LIBRARYDIR=~/Documents/boost_1_53_0/stage/lib 
-DBoost_REGEX_LIBRARY=~/Documents/boost_1_53_0/stage/lib/libboost_regex.a 
-DBOOST_ROOT=~/Documents/boost_1_53_0 
-DBoost_NO_SYSTEM_PATHS=TRUE 
-DBoost_USE_MULTITHREADED=FALSE 
-DBoost_USE_STATIC_LIBS=OFF 
-DBoost_USE_STATIC_RUNTIME=OFF 
-DBoost_ADDITIONAL_VERSIONS="1.53.0" 
-DBoost_DETAILED_FAILURE_MSG=TRUE 
-DBoost_NO_BOOST_CMAKE=ON 
-DBoost_DEBUG=TRUE 
.. 

这是我在/ home/mnowotka /文档/ boost_1_53_0 /台/ lib目录：

ls -lh ~/Documents/boost_1_53_0/stage/lib 
total 4.4M 
-rw-rw-r-- 1 mnowotka mnowotka 2.6M Apr 11 10:49 libboost_regex.a 
lrwxrwxrwx 1 mnowotka mnowotka 24 Apr 11 10:10 libboost_regex.so -> libboost_regex.so.1.53.0 
-rw-rw-r-- 1 mnowotka mnowotka 1.9M Apr 11 10:10 libboost_regex.so.1.53.0 

这是就是我从cmake的获得：

我只有一个问题：为什么？

我做错了什么？这让我疯狂....

（顺便说一句：没关系，如果我设置Boost_USE_STATIC_LIBS和Boost_USE_STATIC_RUNTIMEON或OFF - 它不工作要么...）

Answer 1

1. 你知道，Emscripten目前只能使用模块（例如Boost,Boost-Regex）它编译的源代码？换句话说，Emscripten不能使用动态库或预编译的静态库！

   • 所以你必须为升压正则表达式添加源代码到你cmake的文件，并共同建立他们（我没有做过cmake的相当长的一段时间，所以我不能告诉你怎么做）。

   • 或者你可以从cmake的取出支票升压正则表达式和硬编码必要引用

   无论你选择做什么，你就必须建立升压正则表达式与Emscripten也是！

2. 至于Emscripten，你应该使用Boost_USE_STATIC_LIBS=ON，因为动态库目前不Emscripten支持（见上文）。

3. Emscripten也不支持调用pthread*或任何并发处理。你应该在代码中搜索这些东西。

对不起，声音如此不利，但目前使用的库用Emscripten没有一块蛋糕。
