[Bug 1639531] Re: GCC compiles programs to shared object instead of executable, preventing GUI file managers from executing programs
The problem is not that it's impossible to work around the incorrect default. The problem is the incorrect default itself. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to shared-mime-info in Ubuntu. https://bugs.launchpad.net/bugs/1639531 Title: GCC compiles programs to shared object instead of executable, preventing GUI file managers from executing programs To manage notifications about this bug go to: https://bugs.launchpad.net/gcc-defaults/+bug/1639531/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1639531] Re: GCC compiles programs to shared object instead of executable, preventing GUI file managers from executing programs
This isn't a bug. Ubuntu has setup GCC with "pie" flag enabled for some unknown reason, and this causes executable output to be tagged as shared library. Use "-no-pie" with GCC when compiling. If using Qt Creator / QMake add this to your project file unix:QMAKE_LFLAGS += -no-pie All will work fine after that, and your system will see your local GCC compiled executables tagged as "executable", and Nautilus or any other file browser will be able to run it via click as usual.

This is serious bug and is really counter-productive in 21 century when downloading some portable archive and cannot launch software, Very troublesome. This way is one way to scare people back to Windows. affects 20.10 and 21.04 too, please raise voice people. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to shared-mime-info in Ubuntu. https://bugs.launchpad.net/bugs/1639531 Title: GCC compiles programs to shared object instead of executable, preventing GUI file managers from executing programs To manage notifications about this bug go to: https://bugs.launchpad.net/gcc-defaults/+bug/1639531/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Admittedly the magic for x-sharedlib is the one that's much less useful, shared libs are typically called *.so or *.so.[0-9\.]* :-) But I wouldn't dare just removing all magic from x-sharedlib... unless someone can prove that the ELF file format makes no actual difference between shared libs and executables?

It should be noted that glibc's ELF loader (ld-linux.so, exact name depending on architecture) is a shared object and a valid program, but doesn't have an interpretor header, but that's the only exception I aware of. IOTH, glibc's libc.so is a shared object with a valid interpretor, making it a valid program (try it !). Reporting such library as a program might be misleading for end user. Anyway, PT_INTERP header not at a fixed location in the ELF file, so it cannot be described in shared-mime-info database.

That's not going to happen unless somebody has a patch. Reading comment 4, that seems unlikely. If you have applications that require this deep level of knowledge of the different formats, you'll probably want to use something more precise than the shared-mime spec.
