[Qgis-developer] problems building c++ qgis plugin and/or qgis

[Tasos Varoudis]

Hello all,

I have been trying to build a qgis C++ plugin with no success… in different test platforms too (including building qgis from source).

I started by doing the simple steps in the QGIS Compile/Style document for 1.6.0 (i think) and using as a QGIS_DIR path all possible combination and hacks… Qgis App dir, Qgis source dir from github(without building it, a hybrid folder with Qgis source and "lib" folder from the App dir to cheat without building.
But I had no success.

(python is a no-go!)

I end up getting this: (of course with the 'hacked' lib folder)

I tried to do all the lame hacks because I have tried to build Qgis from source in both MACOSX10.8 and Ubuntu12.04 with no luck!
Im not sure if I do something wrong. Im not that inexperienced in *nix systems...


MacOSX 10.8 with homebrew:
grass building is a problem…
geos is there:
brew -v info geos 
Homebrew 0.9.2
geos: stable 3.3.5
http://trac.osgeo.org/geos
/usr/local/Cellar/geos/3.3.5 (367 files, 8.8M) *
https://github.com/mxcl/homebrew/commits/master/Library/Formula/geos.rb

In Ubuntu cmake is OK but the build near the end. SIP problem?

Any ideas? Links to read? Maybe use an older ubuntu version?

Maybe I have taken a wrong turn somewhere and I keep doing the same mistake?

Thanks a lot!

Best,
