Usage of LD_PRELOAD

[Matthieu CASTET <matthieu dot castet at parrot dot com>]

Hi,

I am trying to use LD_PRELOAD on cygwin, but I don't manage to make work.
I suppose I do something wrong when creating my library.

What I do is :

$ cat << EOF > /tmp/toto1.c 
#include <sys/stat.h>
int chmod(const char *path, mode_t mode)
{
  printf("123\n");
  return -1;
}
EOF

$ module=toto1 gcc -shared -o /tmp/cyg${module}.dll    
-Wl,--out-implib=lib${module}.dll.a     -Wl,--export-all-symbols    
-Wl,--enable-auto-import -Wl,--whole-archive /tmp/toto1.c -Wl,--no-whole-archive

$ export LD_PRELOAD=/tmp/cygtoto1.dll

$ chmod a+w /tmp/toto1.c <-- chmod isn't redirected here (but the 
library is loaded).


Any idea why it doesn't work ?

Thanks

Matthieu
