Qwbfs crash when click on "Select partition"

[Nekmo]

This program is inusable. When I click on "Set the current partition" select input, Qwbfs closes without any message error.

System: Arch Linux x86_64. Qwbfs version: 1.2.5.

Did you started it in root ?

Which Qt version ? 32 or 64bits ?

32 bits

[PeakiNPC]

me too, i have archlinux 64 bits this typing in terminal:

Same here. I installed the binary + built myself the package.

[pasnox]

Will check that if i got time during the weekend

[Salamandar]

By the way I can't compile it a second time, it complains about the missing libfresh… But it worked the first time O.o So I could'nt compile it with debug symbols to have more info.

[pasnox]

Do use shadow builds, aka out of tree source builds:

• unzip archive.zip to qwbfs
• create a qwbfs-build-release (or debug) at same level
• qmake ../qwbfs/qwbfs.pro -r
• make

This allow to keep the source folder clean so u can do many builds as u like using different build folders.

[Salamandar]

Yeah, that's what I did like specified in the Readme ;) I found the problem for the build : There is libfresh_debug.a in the build folder, but g++ is searching for lfresh (libfresh.a, without _debug). A manual file copy is enough to solve the problem for now.

[Salamandar]

Yeah, well, debug symbols don't help so much :

Program received signal SIGSEGV, Segmentation fault.

[Salamandar]

Hmmm, in fact the debug build is… not a debug build. I had to add manually "-g" to the makefiles… :-1:

[Salamandar]

I commented the lines 90, 162,163 in the qwbfs/src/models/PartitionDelegate.cpp, and it works, but the partition names are only visible with the drop-down menu closed AND the cursor on the drop-down menu.

[pasnox]

Which Qt version we speak here ? Can reproduce on OSX... will fix now but only in git (no time to create new release for now)

[pasnox]

Fixed in master and branch 1.2.x. Taggued 1.2.6 version.

Just build from source to avoid crash, will try to produce packages in time, but clearly don't rely on that for a while ;)

[Salamandar]

Got it. I don't understand the lines :

            macx:LIBS *= -lfresh_debug
            else:LIBS *= -lfreshd

I am on Linux but I need -lfresh_debug, not -lfreshd.

[Salamandar]

Well the fix works by me :D

[pasnox]

That's weird, linux default to append a d for debug libs, maybe i wrongly setted to _debug on linux for fresh, i will check. But normally release builds should be fine by now. EDIT: Indeed fresh do generate _debug for unix and d for windows. I will fix. Thanks

[Salamandar]

Great :D
