当我尝试使用std :: filesystem :: path作为函数参数时,它会在我的机器上发生段错误.这是一个最小的例子: #include <filesystem> void thing(const std::filesystem::path& p) { return; } int main() { thing("test"); return 0; } 此代码段会导致以下来自gdb的回溯: #0 0x0000563a5a3814b3 in...

#include <filesystem> namespace fs = std::filesystem; int main() { fs::path aPath {"../"}; return 0; } 您可以在 else 子句中 try_compile for boost::filesystem 并传递一个可在源文件中使用的指令,您可以在其中决定是否要使用 c++17 文件系统或 boost。 原文由 Ashkan 发布,翻译遵循 CC ...
This string is suitable for use with OS APIs. NotesThe conversion function (3) is provided so that APIs that accept std::basic_string file names can use pathnames with no changes to code. ExampleRun this code #include <cstdio> #ifdef _MSC_VER #include <fcntl.h> #include <io.h> #...
The problem (the mutant string) is visible in the assembly, so I am assuming that it looks like a compiler bug. Assembly: std::filesystem::path _badPath = std::filesystem::path(L"c:\\"); 00007FF7F0FBA1D5 xor r8d,r8d ...

可以把这个命令加到/etc/profile文件中 export LD_LIBRARY_PATH=./lib(这里建议使用绝对路径)或者写入~./bashrc文件,既可以永久生效,也可以将这个libmymath.so放到操作系统的lib目录里面,就是/lib/目录下面即可 还可以在/etc/ld.so.conf里面增加libmymath的绝对路径,然后执行命令ldconfig -v,让配置生效,使用命令...
