camstream compile error

I'm trying to get my logitech quickcam 4000pro webcam to work in RHEL 4.
I have the pwc driver installed already but am getting errors trying to install camstream.

When I try to ciompile it gives a whole bunch of errors that look like this:

Code:

Only there are alot more of them. I'm using camstream0.26.3, qt-2.3.1-5,
qt-devel-2.3.1-5, gcc 3.4.4. I've tried using the most recent snapshot and
it gave me errors about the soundcard, I wasn't really expecting that one to
work. But I also tried 0.26.2 and it gave me the same udefined reference
errors. Does anyone have any ideas?

looks like it ( the linker) is having trouble picking up the qt libs, or the qt version you have does not meet the requirements for the package. where is qt installed? does:

Code:

echo $QTDIR

give you a response when you run the command?

is the path to the qt libraries in /etc/ld.so.conf and ldconfig run or are you using a flag to tell the linker where the libraries are?

nmayotte · 12-06-2005, 02:41 PM

Here are these:

[root@mlemons camstream-0.26.3]# echo $QTDIR
/usr/lib/qt-2.3.1/
[root@mlemons camstream-0.26.3]# more /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/lib/qt-2.3.1/lib

One thing I should note is that I have qt & qt-devel 2.3.1 installed parallel to versions 3.3.3. Could this be causing my problems? If I remove 3.3.3 I have a feeling that it will break quite a few things on my system. Before I run the ./configure I do QTDIR=/usr/lib/qt-2.3.1/ and export QTDIR...

yeah i wouldn't recommend removing the 3.3.3.

take a look at the config.log file in the source directory and see what it says when it's checking for the qt libs and headers, there may be a clue there as to what and where it's looking.
