When I cross compile the following program, opening /dev/null fails and
instead the whole install path of /cygwin64/dev/null is visible.
Is there a way to make fopen respect / as the root directory in a cross
compiled program for windows?
example output...
Roger@interocitor:~
$ x86_64-w64-mingw32-g++ -o writenull.exe write2null.cc
Roger@interocitor:~
$ writenull.exe
/dev/null did not succeed
Roger@interocitor:~
$ gcc -o writenull write2null.cc
Roger@interocitor:~
$ writenull
/cygwin64/dev/null did not succeed
C Code that was compiled...
#include <cstdio>
int main(int argc, char **argv)
{
FILE *errfile1 = fopen("/dev/null", "w");
if (!errfile1) // must be a valid pointer
errfile1 = stderr;
FILE *errfile2 = fopen("/cygwin64/dev/null", "w");
if (!errfile2) // must be a valid pointer
errfile2 = stderr;
fprintf(errfile1, "/dev/null did not succeed\n");
fprintf(errfile2, "/cygwin64/dev/null did not succeed\n");
return 0;
}
