[SOLVED] Font antialiasing of qt3 apps in slack64

The linker then of course managed to link to the correct ones, so the package was ok.

Just guessing, but maybe the Slackbuild also worked ok for Eric because he already had the compat32 support working, but then Pat rebuilt the package without that...

Yes, it may be the case. But I wonder how a 64bit lib could link to a 32bit lib... After all, it's weird...

I did verify that -L/usr/lib64 (or -L/usr/lib${LIBDIRSUFFIX}) works just as well. Anyway, thanks again! Very good detective work there.

Yes it should be. But it seems that some part of qt3 doesn't realize that it's in a x86_64 environment(it seek libs in /usr/X11R6/lib /usr/lib but not /usr/X11R6/lib64 /usr/lib64).... Anyway, it is good that qt4 is smarter

Added Grissiom's line. Now it works.

I'm glad you guys got it figured out. For reference, I do have the 32-bit libs installed (which supports the current theory.)

o_O Really? So is your newly built qt3 a 32bit lib or a 64bit lib? You can run qt3 programs flawlessly?

No, I had the 32 bit libs in the qt3 configure's default search path, but the multilib compiler correctly linked qt3 with the correct 64-bit versions. With out the extra flag, the qt3 configure will not see the libs and not build against them since it didn't look in lib64 for some reason.

At least that's what I understand of the situation.

Just an FYI:

The bug in the slackbuild script is still present in the -current tree, and it's TWO years later.

I'm still working with 13.0, but I DL'ed the code out of the current tree by mistake, and noticed that it will NOT build correctly without the '-L/usr/lib64' hack.

My system is still pure 64bit, so that triggered the configure bug again.
