Debugger doesn't run on SAMBA share
« on: November 03, 2017, 07:11:43 pm »
Hi All,
I've searched the forum to see if anyone else has experienced this issue but have not found any posts so far.

Here's the problem:
When my project is saved on a SAMBA share the debugger won't work. The debugger runs but won't stop at the cursor nor any breakpoints. It simply run to the end and reports that it completed successfully. If the project is saved on the local file system, the debugger works as expected.

There are no spaces in the SAMBA share path nor in the project file names. The project runs and compiles perfectly but it just won't debug. Has anyone else experienced this issue. Should it be reported as a bug?

Here's my environment:
Centos 7
Code::Blocks 16.01
gdb

Does it work with only gdb on command line?

Can you show us the full debugger's log?
You should enable it in the settings of the debugger.

can you post a debug log, where you try to hit a breakpoint?

And can you show the log from command line debugger where the breakpoints really work?
But please use fuller paths for the break commands.

In general I'm really surprised you're able to get this far when using paths like this one
Code
/run/user/1000/gvfs/smb-share:server=192.168.1.5,share=

There are so many special characters, which might confuse programs in some many different ways.

I'm not sure how to do that. I just Googled it but didn't see anything helpful

The path is provided to Code:Blocks by the Linux Mint desktop.

I suspect that you are correct and the debugger doesn't like some of the characters in the path. I don't want to introduce possible additional bugs into my code by using a suspect path so I'll move the projects on to the local file system

Thanks for all your help.

All the commands are available in the log you're posting so you need to just execute them in the terminal.

Generally it is better to share projects with vcs like (git, svn, hg, etc) and not using file sharing software.

the commands for gdb appear with a single ">" in the log.
not all commands are really necessary

Quote
/bin/gdb -nx -fullname -quiet  -args /run/user/1000/gvfs/smb-share:server=192.168.1.5,share=public/CodeBlocksProjects/debugTest/bin/Debug/debugTest
starts gdb (i am amazed that this works right away)

Quote
show version
shows version (not necessary)

so this should be the commands you need:
Code
/bin/gdb -nx -fullname -quiet  -args /run/user/1000/gvfs/smb-share:server=192.168.1.5,share=public/CodeBlocksProjects/debugTest/bin/Debug/debugTest
set confirm off
 set breakpoint pending on
set unwindonsignal on
catch throw
directory /run/user/1000/gvfs/smb-share:server=192.168.1.5,share=public/CodeBlocksProjects/debugTest/
break "/run/user/1000/gvfs/smb-share:server=192.168.1.5,share=public/CodeBlocksProjects/debugTest/main.c:6"
run
