Yes, it could be the lib of file that invoke some function when loaded and
maybe that function has some blocking procedure.
In my test, I just simply made dummy function
/*
* compile with gcc in Windows (mingw64)
* $ gcc -shared -o test.dll test.c
*
* in Linux (bash in Windows 10)
* $ gcc -shared -fPIC -o test.so test.c
*/
#ifdef _WIN32
#include <windows.h>
unsigned int sleep (unsigned int seconds) {
Sleep(seconds * 1000); // Sleep needs in milliseconds while sleep needs
in seconds
return 0;
}
#elif defined __unix__
#include <unistd.h>
#endif
int test() {
sleep(10); // this is blocking
return 10;
}
If you want to run/load the `test` function in Linux, somehow you have to
hard-code the lib name to point to current directory (e.g.
`loadlib("./test.so")`). I'm not sure why option `-L.` doesn't work. After
looking around, you need to somehow edit LD_LIBRARY_PATH but since this is just
test, that would be unnecessary
