Just encountered this problem today, and can confirm on Ubuntu 8.04.1, x86_64.
I made sure to use gnatmake -g option to enable debugging symbols. This GDB was configured as "x86_64-linux-gnu". (gdb) file matrix "/home/username/projects/ada/matrices/matrix": not in executable format: File format not recognised The file is definitely executable. ** Changed in: gnat-gdb (Ubuntu) Status: New => Confirmed -- gnatgdb does not recognize Ada executeable https://bugs.launchpad.net/bugs/219342 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
