我尝试构建基于 CppCMS 的网页。它在 Gentoo (GCC) 下编译和工作。但是我在尝试在 FreeBSD 下构建应用程序时遇到了问题（托管服务提供商的帐户）。默认编译器是 Clang。
我下载了 CppCMS 包并导出了几个变量：
export CC=gcc48
export CXX=g++48
export LD_LIBRARY_PATH=/usr/local/lib/gcc48
然后像往常一样：
cmake -DCMAKE_INSTALL_PREFIX=/home/mrozigor/libs ..
make
此时可能有问题，因为它在所有测试（make test）中都失败了，并且出现了分段错误。但我试图构建我的应用程序并使用命令：
PATH=$HOME/libs/bin:$PATH CPATH=$HOME/libs/include:$CPATH LIBRARY_PATH=$HOME/libs/lib:$LIBRARY_PATH ./build.sh
它构建它。但是当试图执行它（LD_LIBRARY_PATH=$HOME/libs/lib app）时，它也会因 SEGFAULT 而失败。
当我尝试ldd libcppcms.so在 CppCMS 构建目录中执行命令时也很有趣，它失败了ldd: libcppcms.so: Shared object "libcppcms.so" not found, required by "ldd"，但是当在 lib 安装目录中尝试相同的命令时，它指向正确的对象。
这是链接某些库的问题吗？或者也许一些环境变量指向一些 Clang 依赖项等？
[编辑]
尝试使用选项： cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=/home/mrozigor/libs -DCMAKE_C_COMPILER=gcc49 -DCMAKE_CXX_COMPILER=g++49 -DCMAKE_LIBRARY_PATH=/usr/local/lib/gcc49 .. LD_LIBRARY_PATH=/usr/local/lib /gcc49 使 LD_LIBRARY_PATH=/usr/local/lib/gcc49
仍然具有给定回溯的 SEGFAULTs，基于转储文件：
