upgrading qt on slackware 8.0

[NoUse]

i'm trying to compile qt version 2.3.2 on slackware 8, and i run into some problems. i have updated gcc to version 3.03. it looks to me (although i am a noob) that i'm missing libmng.h. if anybody has an idea of what i need to do to fix this problem, like install some package i missed or download that particular header file and put it somewhere, i'd be grateful. here's the dump of the error i got.

You need to install the development portion of libmng (however slackware manages packages, I don't know).

You could also *not* include the -system-libmng option when you configure qt, then it would build libqt without libmng support which *i think* is ok for showeq.

Good luck.

Similarly you will need libjpeg/libpng development packages or not include the associated "-system-???" options when configuring.

thanks yenndor...

i found those files from the redhat ftp site, then tried to install them with kde's package mangement tool. one of them installed fine, but the other two had some big dependency errors and confused me. so i just did make clean then configure again without those three options and after about an hour and a half it was finally done compiling successfully.

i wasnt able to find those files as slackware packages, but i'm pretty new to this all so i may have just missed something. if any slackware users out there have some thought's i'd appreciate it. anyhow qt compiled so i'm not too worried about it.

wo0t!

Yendor is correct. I just left out the libmng when I compiled qt-3.2.2. It should work fine after that. Also make sure you rename or move the /usr/lib/libqt-* files because slackware is set to look for the qt files in /usr/lib instead of the QTDIR. So when you run the configure program it always finds the damn qt-2.3.1 libs instead of the newer ones you made. This annoyed me for a while till I finally figured it out

After moving those files or renaming them, just set your QTDIR to /usr/lib/qt-2.3.2 in your .bashrc file like the other howto's on the board explain and you should be good to go.

[NoUse]

in the INSTALL file that came with qt 2.3.2, it suggests to put it in /usr/local/qt or something like that, then adding the environment variables to .profile in your login directory. i found that slackware was using /usr/lib/qt, so i moved all that stuff to /usr/lib/qtbak and put the new stuff in /usr/lib/qt so i wouldnt have to mess with the .profile stuff or modifying that. i figured it would be easier. anyway, it seemed to be because it worked fine.

[Yendor]

You can also use --with-qt-dir=/path/to/qt

when configuring showeq to have it find the proper qt. this is the preferred method as it allows the system qt to remain installed for the applications that need it.

(setting QTDIR environment variable has the same effect)
