How do you know what -lqt-mt is?

Does anyone know how you can figure out where a library such as -lqt-mt is? I have a compile that says it cannot find it. But I see something called libqt-mt.so in my /usr/qt/3/lib directory.

Any thoughts?

Joe

Hmm, seems you already know where it is

Add -L/usr/qt/3/lib to the compile line and see if that helps.

As for locating libraries I'm not sure. Usually I might try to ldd a certain binary and hope it dynamically links to the one I want. For instance: ldd /usr/kde/3.1/bin/kate will print out a bunch of libraries. And then I try to find the location of the one I'm looking for. Haven't had to do this much though ...

First, I circumvented the issue by making a dir called /usr/qt/3/lib64 that contains all of what /usr/qt/3/lib contained. Now, the configure gets further (some other bullSH*$ problem). Anyway, I need to know why the configure was looking at /usr/qt/3/lib64 when that directory never existed. Someone told it to look in that directory and it wasnt me. What file is configured to do that. Is this a bug?

How could I be the only person seeing this?

Thanks
Joe

lib64 eh? What architecture are you running? The new AMD's or Itanium? I would fathum that when you emerged qt something was awol and it somehow detected your machine as 64bit perhaps?

Do you have any specific 'exports' that affect QT. Namely, QTDIR="/usr/qt/3" and maybe LD_LIBRARY_PATH="/usr/qt/3/lib:/usr/kde/3.1/lib (this is just an example and I don't think you really need this though you might) Does configure fail when it does it's "Checking for QT ..." parts?

Now, if you really are 64bit, I'm not really sure. What are your other errors now?

Jesse,

you are totally correct. All my failures are at the checking for qt parts.

Here is my /etc/ld.so.conf

/usr/local/lib

I have no clue why I'd be having these issues. Just for fun here is more info

here is my ldconfig -v | grep qt

libqthreads.so.0 -> libqthreads.so.0.0.1
libqthreads.so.12 -> libqthreads.so.12.3.0
/usr/qt/3/lib:
libqt-mt.so.3 -> libqt-mt.so.3.2.2
libqtmcop.so.1 -> libqtmcop.so.1.0.0

I just dont see why that configure step would look for qt libraries in /usr/qt/3/lib64 That directory didnt exist at all. In fact, the only lib64 dirs that I have (that I know of) are /lib64 and /usr/lib64

Only after making a copy of /usr/qt/3/lib to /usr/qt/3/lib64 did I get past that 'checking for qt' step.

What do you think now?

Joe

Well that's just odd

Lemme get this straight. You run ./configure and it goes on merrily until it reaches Checking for QT ... At this point it fails because the libs are not in a specific directory /usr/qt/3/lib64 ?

What package are you trying to build? Maybe it's their ./configure that's messed up. Does it have a ./autogen.sh file or maybe a Makefile.cvs in the toplevel directory. If it does either do ./autogen and reconfigure or do make -f Makefile.cvs and reconfigure.

There's no reason configure shouldn't look in lib when everything else tells it to.

Well, I type "emerge kportage" or "emerge ksambaplugin" and it just goes until 'checking for QT' and then it takes a dump.

You're level of stumpitude on this issue is appreciated, though. If you notice the last 50 posts I've made in the past 3 days have been about this. I had the problem months ago, posted, got nowhere and quit. Now, I am fighting the good fight.

I REALLY WANT TO SOLVE THIS
