defect: qca-2.0.0 missing -L/opt/local/lib when building examples?

[rechner@…]

When I tried to install kdegraphics4 the building of qca failed:

--->  Building qca
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_qca/work/qca-2.0.0" && make all " returned error 2

So I went to the build directory

/opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/qca/work/qca-2.0.0/examples

and called the long last command with an added "-L/opt/local/lib" as the first option to "g++-4.0". After that "port install qca" completed without problems.

By the way: "-I/opt/local/lib" is in my "CFLAGS" environment and many other ports compiled without problems. But I don't know much about compiling C programs, maybe I'm on the wrong track here...

See also #20241.

This should be fixed now. Please clean the port and try again.

As I understand it from looking at #20241 this is fixed due to a change in qt4-mac? So I would have to recompile qt4-mac just to test the fix? It takes about a full day (24 h) to compile that package on my G4 iMac (and I never leave it running at night, since it is in my bedroom). So I think I'll wait with that until there are KDE 4.3 Portfiles (maybe in a week or two?), so I can try them with the then latest qt4-mac.

I did try to "port -d sync ; port clean qca ; port -f build qca", but since the qca Portfile still dates 14 May it was to expect that it would still fail with the missing "-lpng", which it did.

Yes. I did try installing qca after rebuilding qt4-mac and it works for me.

Ok, good. I'm sure it would work for me too, and this bug is rightly closed. I will keep an eye on the problem when I reinstall qt4-mac, though.
