qt5-5.15.2-i586-10 /usr/lib/qt5/bin/uic -h = Segfault .

Hello All , While trying to SlackBuild.wireshark (both 3.4.4 & 3.4.7) .
this is running a , Not recently updated on 32bit -current . To small of data download available most of the time .

From the Changelog.txt , This is the latest version of qt .

I am uncertain if there has been an update to a *Lib that may be effecting this Segfault . If there is please inform me of such .

Looknig around further , Taken from the strace file , I find ...

4 drwxr-xr-x 3 root root 4096 Apr 1 15:45 /usr/lib/locale/en_US.utf8/

While the uic was looking for a captialized ... /usr/lib/locale/en_US.UTF-8

I linked en_US.utf8 to en_US.UTF-8 & uic -h still segfaults .

uic -h works perfectly here , -current up-to-date 64bit

babydr · 08-08-2021, 04:55 PM

@USUARIONUEVO , Thank You ...

Sorry I didn't update the posting until a couple of days ago that this is on 32Bit .

Yes , I concur that on my other 64bit systems the 'uic -h' works without Segfault or any other error .
And of course I have critical things in process on the 32bit system atm .
And no other true 32bit systems left in running condition to reload 32bit -current onto .

chris.willing · 08-08-2021, 06:21 PM

This probably won't help you much except to confirm that the SlackBuild itself is OK.

I don't have a physical 32bit machine but I use a VM to test 32bit builds. In that 32bit VM, uic -h works as expected at the command line. When building wireshark 3.4.7, I see:

Code:

 * ILBC, iLBC decoder, <https://github.com/TimothyGu/libilbc>
   Support for iLBC codec in RTP player

We are on tag v3.4.7.
version.h has been updated.

[  0%] Building C object CMakeFiles/shark_common.dir/cfile.c.o

etc., and the build continues successfully to produce a wireshark package.

The VM is fully up to date. If your system is not, it could be an issue since the updates in -current are quite frequent and one (some) of uic's dependent libraries could be out of date. If you're reluctant to do a complete update, I suggest you run 'ldd /usr/lib/qt5/bin/uic' and then, for each of the libraries mentioned, check that it it the most recent version available i.e. check which package each library is installed from and try to upgrade it (slackpkg upgrade ...).

Also, I don't think the locale thing you mentioned matters since my 32bit VM also has (uncapitalized) /usr/lib/locale/en_US.utf8/

A complete reformat of all partitions and install of -currect for 32bit .

The date of download was 2021-08-27 .

I see since then a completely is a new qt5-* version because the previous version had security problems .

I'll try once more with just a slackpkg update & see how it works after that .

Just making noise atm . JimL

babydr · 09-01-2021, 09:39 PM

Same exact error as before .

All packages are updated as of today , except KDE & kernel .

Code:

# cat /etc/slackpkg/blacklist | egrep -v '^(#|$|[[:space:]]$)'
kde/
kernel-generic.*
kernel-huge.*
kernel-modules.*
kernel-source

Any thing else that would be helpful in getting this problem solved is greatly appreciated .

Again , it is 32bit slackware-current . Everything installed . Except /extra/ .

Code:

We are on tag v3.4.7.
version.h has been updated.
-- Configuring done
CMake Error: AUTOUIC for target wireshark: Test run of "uic" executable "/usr/lib/qt5/bin/uic" failed.

It's working here on 32-bit -current. What type of processor does your machine have? I'm thinking maybe uic has started to use opcodes that aren't present in older CPUs.

Yeah... I'm afraid that with such an old 32-bit CPU we really can't go out of our way to fix this issue. If it's any consolation (which I sincerely doubt), 32-bit is circling the drain anyway.

If someone does come up with a patch, I'd take it.

This is the only laptop in residence .
I guess I deed to go look for a decent one that still had cardbus slots & serial port .
Thank you for the research .
Would be nice to know of a work around for compiling wireshark ?
