Currently when you start QGIS compiled with GRASS (in my case 6.4 on fedora), you get a pop up at the start of QGIS asking you if you want to set GISBASE. No matter what I set there I can’t get it to recognise my GRASS. That is probably just me being dumb, but my problem is more about the popup itself - it blocks QGIS from starting which ruins e.g. tests which need to run headless and I think it isn’t a great user experience as there is no help to tell you how to locate GISBASE. What about using a QgsMessageBar or some other non-blocking technique for alerting the user to the fact that their GISBASE is not found, and providing some help on what the appropriate setting should be?

Thanks!

Hmm I’m wondering if a generic notification signal / slot would be useful….so that any non gui bits of code can push messages up to the UI.

I get:

src/core/qgsproviderregistry.cpp: 131: (QgsProviderRegistry) [7ms] Checking /usr/local/qgis-master//lib/qgis/plugins/libgrassplugin6.so: ...invalid (has type method)
src/providers/grass/qgsgrass.cpp: 317: (init) [2ms] do init
src/providers/grass/qgsgrass.cpp: 379: (init) [0ms] GRASS gisBase from GISBASE/WINGISBASE env var is:

src/providers/grass/qgsgrass.cpp: 384: (init) [0ms] GRASS gisBase from QSettings is: 
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 411: (init) [0ms] GRASS gisBase from configure is: /usr/lib/grass
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 457: (init) [0ms] GRASS was not found in '/usr/lib/grass'(GISBASE), provider and plugin will not work.
src/providers/grass/qgsgrassprovidermodule.cpp: 1002: (isProvider) [2ms] init failed

I went and checked and it seems like make gets the wrong lib dir so I changed to do:

-DGRASS_PREFIX=/usr/lib/grass64 

And now I get:

src/providers/grass/qgsgrass.cpp: 317: (init) [2ms] do init
src/providers/grass/qgsgrass.cpp: 379: (init) [1ms] GRASS gisBase from GISBASE/WINGISBASE env var is: 
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 384: (init) [0ms] GRASS gisBase from QSettings is: 
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 411: (init) [0ms] GRASS gisBase from configure is: /usr/lib/grass64
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 457: (init) [0ms] GRASS was not found in '/usr/lib/grass64'(GISBASE), provider and plugin will not work.
src/providers/grass/qgsgrassprovidermodule.cpp: 1002: (isProvider) [0ms] init failed

I also tried explictly setting GISBASE as env var to /usr and then I get:

src/providers/grass/qgsgrass.cpp: 317: (init) [1ms] do init
src/providers/grass/qgsgrass.cpp: 379: (init) [1ms] GRASS gisBase from GISBASE/WINGISBASE env var is: /usr/
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 384: (init) [0ms] GRASS gisBase from QSettings is: 
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 411: (init) [0ms] GRASS gisBase from configure is: /usr/lib/grass64
src/providers/grass/qgsgrass.cpp: 563: (isValidGrassBaseDir) [0ms] isValidGrassBaseDir()
src/providers/grass/qgsgrass.cpp: 457: (init) [0ms] GRASS was not found in '/usr/lib/grass64'(GISBASE), provider and plugin will not work.
src/providers/grass/qgsgrassprovidermodule.cpp: 1002: (isProvider) [1ms] init failed

If I go to the help -> about -> providers box, I get both grass 6 and 7 listed there

Probably too much information I know :-P
