Issues building 4.3.2 x11 shared version on Ubuntu 7.10

[rickbsgu]

Trying to shared build qt4 on Ubuntu 7.10.

After doing the configure, I start the build - qtcore seems to build ok, but the subsequent builds (x11, gui, etc.) rely on qtcore. The build fais with 'cannot find -lQtCore' during the link. The -L is pointing to the right place, and there are the following qtcore entries in the lib directory:

libQtCore.la
libQtCore.prl
libQtCore.so.4.3.2
libQtCore.so.4.3.2.debug

Here's the config line:



./configure -prefix (unzip path) -debug -fast -no-qt3support -optimized-qmake


The installation is the same as the build directory (which the build process seems to acknowledge and tells me not to do a 'make install'.) I've tried removing everything but the -debug flag, and I still get the same result.

Wazzup? Is the build process needing to do a 'ln -s' of one of the libqtCore.* entries to libQtCore.{so,a} or some such thing? Why can't it find the -lQtCore?

Scratching my head... for the interim I've built it statically and that will have to do, for now.

Ok, I see partially what's going on - the submakefiles want to create sub-version softlinks to the major version, then copy the whole set up to lib.

For some reason, that's failing on Ubuntu. If I make the links manually, the build proceeds.

Still thinking... Maybe there's a permissions problem?

Hm. So, I created a script to make the links in the lib each time the build failed, then restart the make until it finally completes. A little wanky, but it works and I have a good debug shared build.

Yeesh. You'd think after 'n' years, the trolls would have this figured out.

I'm sure Qt is tested on Ubuntu, as it's the favourite distro of some of the trolls. Maybe you experience some permission or filesystem problem?

Yeah, that's what I thought, too.

I checked the permissions, etc. All seems to be fine. Might be an fs issue of some sort - I'm doing this in an Ubuntu 7.10 VM on Parallels (Mac), across a cifs mount to the Mac disk. Might be something there, although I seem to be able to do all of the operations by hand ok.

Anyway, the workaround got me going.

Thanks, anyway.

You might report that to the Trolls. I'm sure they'll take a closer look at it.

[rickbsgu]

Ok, I'll have to figure out how to do that.

This is the open source X11 version - I'll get on TT's site and see if I can find the appropriate channel.

(On edit) Followup: Done. Also a problem I was having with the Mac build.

Cheers,
