QTCreator does not recognize the executable while

Question

I have installed QTCreator in ubuntu 12.04 through sudo apt-get install. My problem is that QTcreator is not able to recognize the executable in debug mode, although it is running fine without debugging..when I simply run my program. The error which the QTCreator throws at me while debugging is:

s/Prog": not in executable format: File format not recognized

I can use gdb outside QtCreator. All my tool chain just shows me GCC(x86 64 bit)...is this setting fine. If not please recommend.

Answer 1

I had the same problem on my Ubuntu 13.10 and what I did was sudo apt-get install gdb and after that the debugger worked fine. What seemed strange for me, however, is that although I already had gdb and gdb64 in /usr/bin, apt didn't say that gdb is already installed and it installed it(maybe an upgraded version).

Also check out your tool chain and make sure you're using gdb 64-bit if your executable is built on 64-bits.

I use Qt Creator 3.1.0, maybe you should upgrade your QtCreator as well.

Hope this helps.
