qtiplot 0.9.7.9 fails to build on Snow Leopard

[Stochasticus@…]

I was updating all outdated packages and qtiplot gave me a problem. I'm in the middle of a job that needs it so I don't want to uninstall the working version unless I'm sure it will fix the problem otherwise I'd do the uninstall and re-install test. The problem seems to be here but I'll attach the full log from a cleaned installation as well:

I'm gettting this error too, on a fresh install of 10.6.2.

It seems that adding the missing library to the compilation file does the trick. See attached portfile.

hmmm that's interesting. I thought zlib was already pulled in by Qt, but maybe the cocoa version doesn't do so... That wuold also explain why I can't reproduce the problem here on Leopard. (qt4-mac builds per default the cocoa variant on snow leopard, since the carbon variant isn't 64 bit ready)

Your patch seems a bit hacky though. Could you please try to add zlib to SYS_LIBS, say

- puts $confFD "SYS_LIBS = -L${prefix}/lib"
+ # snow leopard seems to need zlib explicitly, see #23272
+ puts $confFD "SYS_LIBS = -L${prefix}/lib -lz"

If this works, add zlib as additional dependency and feel free to commit, thanks.

This patch is indeed far cleaner. I am still not used to the build.conf file.

I confirm that it works with Snow Leopard 10.6.2 and the latest qt4-mac of Macports (4.6.1_0). I made a patch with the proposed modification and the addition of zlib as a dependency. I don't have commit rights, so since the maintainer agreed to it, could someone commit it ?

I'd like to install qtiplot an an iBook G4 with Tiger 10.4.11 ...

Build stops with:

/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: Undefined symbols:
_gzclose
_gzerror
_gzopen
_gzread
_gzwrite
collect2: ld returned 1 exit status
make[1]: *** [qtiplot.app/Contents/MacOS/qtiplot] Error 1
make: *** [sub-qtiplot-all] Error 2

I applied the given patch and it builds now! But doesn't that neglect the argument why it worked on Leopard and not on Snow Leopard?
