boost - cmake 找不到 boost 线程

标签 boost cmake ubuntu-12.04 emscripten

我正在尝试使用 emscripten 将一些项目编译为 js。该项目使用cmake作为构建工具。

这就是我调用 cmake 的方式:

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/Documents/boost_1_53_0/stage/lib 目录中的内容:

ls -lh ~/Documents/boost_1_53_0/stage/lib

-rw-rw-r-- 1 mnowotka mnowotka 1.9M Apr 11 10:10 libboost_regex.so.1.53.0

这是我从 cmake 得到的:

我只有一个问题:为什么？

我做错了什么？这让我发疯......

(顺便说一句:我设置 Boost_USE_STATIC_LIBS 和 Boost_USE_STATIC_RUNTIME ON 或 OFF 并不重要 - 它也不起作用...)

最佳答案

  1. 您知道，Emscripten 目前只能使用其源代码模块(例如 Boost、Boost-Regex)编译？换句话说，Emscripten不能使用动态库或预编译的静态库!

    • 因此，您必须将 Boost-Regex 的源代码添加到您的 cmake 文件中，并将它们一起构建(我还没有完成 cmake em> 很长一段时间所以我无法告诉你如何)。

    • 或者您可以从 cmake 中删除对 Boost-Regex 的检查，并对必要的引用进行硬编码

    无论您选择做什么，您都必须使用 Emscripten 构建 Boost-Regex!

  2. 对于 Emscripten，您确实应该使用 Boost_USE_STATIC_LIBS=ON，因为 Emscripten 目前不支持动态库(参见上文) )。

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

抱歉，听起来如此消极，但目前使用 Emscripten 库并不是小菜一碟。
