Hi. Since I've moved from FreeBSD 1.0.2 to FreeBSD 1.1.5.1, gdb 4.11
doesn't recognize the executable files that I want to debug. I guess
this is somehow due to the shared libraries.
Here is a sample session:
----------------------------------------------------------------------
/tmp % uname -a
FreeBSD pitonneux 1.1.5.1(RELEASE) GENERICAH#0 i386
/tmp % cat foo.cc
#include <iostream.h>
int main ()
{
cout << "Hello, world.\n";
return 0;
}
/tmp % g++ -v
gcc version 2.4.5
/tmp % g++ -g -o foo foo.cc
/tmp % ./foo
Hello, world.
/tmp % gdb foo

"/usr/real_tmp/foo": not in executable format: File format not recognized.

----------------------------------------------------------------------
/tmp is a symlink to /usr/real_tmp. I built gdb 4.11 under FreeBSD 1.0.2.
gdb doesn't seem to have a switch to tell it do deal with shared
libraries. Should I build a newer version of gdb?
