Hi list, Please see the correspondence below from the pypy team about some failing tests. Specifically, why is test.py producing None whereas test.c is producing the desired results?

Hi Matti, I am able to reproduce this on FreeBSD 10.2: # cat > test.py << __EOF from ctypes import * libc = CDLL("libc.so.7") dlopen = libc["dlopen"] # see <dlfnc.h>: void *dlopen(const char *, int); dlopen.argtypes = [c_char_p, c_int] dlopen.restype = c_void_p print dlopen(c_char_p("libm.so"), c_int(0)) __EOF # python test.py None However, contract this with the C equivalent: # cat > test.c << __EOF #include <dlfcn.h> #include <stdio.h> int main(int argc, char** argv) { printf("%p\n", dlopen("libm.so", RTLD_LOCAL)); } __EOF # cc -o test test.c # ./test 0x800620800 <snip/>
