Problem compiling QUCS

[jd63]

Hi,

I'm trying to compile QUCS (a circuit simulator) which is available in Slackbuilds. Compilation fails with the error:

checking for Qt headers... configure: error: not found

But I have Qt installed. As I understand it Slackware doesn't have separate "dev" packages, so I'm not sure where to go from here.

I'm using Salix 14.1 with Xfce. Thanks for any help. Great distro by the way!

This is weird. Can you try with:

Code: Select all

sudo -E spi -i qucs

Thanks but I'm getting the same error using -E.

The qucs package has never been compiled or run on this platform.
Please send an email to <qucs-devel@lists.sourceforge.net> including your
compiler and Qt version and whether it worked correctly or not. The
'i486-slackware-linux-gnu' line will then be added to the PLATFORMS file included
in this package.

According to the qucs website compilation requires Qt4 with "Qt3 support". http://qucs.sourceforge.net/build.html
Not sure what this means...

Can you post the output of this?

Code: Select all

sudo su
echo $QT4DIR

[jd63]

hmm.... not getting any output at all for that.

But tried this:

qmake --version
QMake version 2.01a
Using Qt version 4.8.7 in /usr/lib/qt/lib

Also maybe this will help from someone who had the same problem with an earlier version?

But I don't really want to start installing old versions of Qt in case it messes up my system.

Try this:

Code: Select all

sudo su
source /etc/profile.d/qt4.sh
spi -i qucs

Thanks gapan, that did it!
