Hi,
I'm trying to build QLoud 0.22 and I can't get pass this error:
/usr/bin/ld: cannot find -lqwt
collect2: ld returned 1 exit status
I built and installed the latest version of qwt and set the
LD_LIBRARY_PATH and also set the right path to the library in
/etc/ld.so.conf.d and still ld can't find it. I'll appreciate any help
here.
Thanks!
Hector

Do you have the *development* libraries for libqwt installed? On my
Mandriva 2007.0 system the rpm package name would be libqwt4-devel
and this is in the "contrib" repositories.
I built and installed the latest version of qwt and
set the
LD_LIBRARY_PATH and also set the right path to the library in
/etc/ld.so.conf.d and still ld can't find it. I'll appreciate any help
here.
LD_LIBRARY_PATH affects how a program links when it executes, not
how it builds, or so I believe. -L/dir/where/lib/is as part of
LDFLAGS could be useful to you.
Good luck....

Is Qwt 5.x installed against Qt 4.x? If you can build Qwt examples
using 'qmake' from Qt 4.x, you will be able to build QLoud also.
5:06 p.m.
Thank you for your responses.
Yes, I built Qwt against Qt 4 using /usr/lib/qt4/bin/qmake in Fedora 7
(the qwt package in the Fedora 7 repository is an older version so I
uninstalled it and downloaded the lates Qwt source). I tried building
some of the Qwt examples included with the source and they built and
ran without any problems, but still I get the same ld error trying to
build QLoud.

Do you have a configure option to set the qwt library path
to /usr/local/lib...? Or one can place it in a LDFLAGS=-l/usr/local/lib... ?
Thank you for your responses.

Yes, I tried exporting LDFLAGS=-L/usr/local/qwt-5.0.2/lib (that's
where the qwt libs are) and still same problem.

Thanks! That did it. I just added:
LFLAGS = -L/usr/local/qwt-5.0.2/lib
to the src/Makefile and it built.
Cheers!

Have you tried to look at LIBS string inside qmake-generated src/Makefile?

Hector,
Will you be so kind to report a concrete Qt4 version you are using?
The thing is, v.0.22 was released to work with Qt v.4.3.0, and I had
not a chance to try QLoud v.0.22 with earlier Qt 4.x versions.
Thanks!
11:04 a.m.
Andrew.
Fedora 7 has Qt v.4.3.0 too.
Thank you for this useful tool!

I had similar problems with building some software. Kfreeflight was an
example. I had an Sid-installed plib which would not link so a compiled my
own local version. Problem was that the configure was too crafty for it own
good :-)
Try LFLAGS=/usr/local/lib -- maybe the configure knows to put the qwt in
itself. Maybe even just /usr/local.
All else failing, this is what I had to do: The big g++ or ld command that
fails with -lqwt not found--run make in konsole (KDE xterm+) or such and COPY
that command! What you may find is something like:
... -L/usr/lib..... -L/usr/local/lib... ...... -L/usr/lib .... -lqwt ....
You can guess what has happened :-)
Go into the last directory in the make, usually src. Paste the command and
either, depending on what follows the -lqwt, delete the -L/usr/lib or move it
after -lqwt and any other local stuff. HIt return to run the command. if this
works now, go back out to the main directory, run make to finish off.
