Description Daniel Franke 2004-01-13 13:58:03 UTC 
Version:           3.0.0b2 (using KDE 3.1.4)
Installed from:    compiled sources
Compiler:          gcc version 3.2.2
OS:          SunOS (sun4u) release 5.8

CVS 2004/01/12

-rw-rwxr-x    1 franke   users        9648 Jul 23 00:07 zombie
./zombie
bash: ./zombie: Permission denied

(kdevelop project 'zombie', these file permissions are NOT set by kdevelop, but by another app)

Try to run zombie within it's project, nothing happens. A _very_ silent error message appears in application-tab (without raising it).

Try to debug the project: 
-- GDB --
gdb /home/franke/devel/zombie/src/zombie -fullname -nx -quiet
(gdb) set edit off 
(gdb) set confirm off 
(gdb) (gdb) 
(gdb) set print static-members off 
(gdb) tty /dev/ttyp1 
(gdb) set width 0 
(gdb) set height 0 
(gdb) set stop-on 1 
(gdb) handle SIG32 pass nostop noprint 
(gdb) handle SIG43 pass nostop noprint 
(gdb) set print asm-demangle on 
(gdb) cd /home/franke/devel/zombie/src 
(gdb) break zombie.c:11 
Breakpoint 1 at 0x10688: file zombie.c, line 11.
(gdb) run 

Program exited with code 01.
-- 

Running 'zombie' in gdb:
(gdb) run
Starting program: /home/franke/devel/zombie/src/zombie
/usr/bin/bash: /home/franke/devel/zombie/src/zombie: Permission denied
/usr/bin/bash: /home/franke/devel/zombie/src/zombie: Permission denied

To know about the reason of 'Program exited with code 01.' would really be appreciated!
Comment 1 Jens Dagerbo 2004-01-13 15:07:35 UTC 
Hmm.. yeah, I can verify that this happens.

KDevelop reports "Permission denied" when you attempt to run the program, but only shows the "code 01" string when you attempt to debug it.
Comment 2 Daniel Franke 2005-01-14 14:44:12 UTC 
kdevelop-3.1.91, KDE-3.3.91 (beta1), CVS 050113

On execution: a konsole window appears that tells the user that the binary was sucessfully not executed ... *ähem* ...  more or less something like this ;)

debugging is still answered with "Program exited with code 01" in the status bar - no more information.

(I know, that's a wierd one)
Comment 3 Vladimir Prus 2005-08-19 12:48:51 UTC 
SVN commit 450870 by vprus:

Before running debugger, check if application is indeed executable.
