[Qgis-developer] TestQgsCoordinateReferenceSystem failed

[Etienne Tourigny]

I assume you are using a 32-bit version  of Ubuntu 11.04? I don't see
this using 64bit ubuntu, gdal 1.8.1

It seems that gdal in 64-bits linux reports differently than i386 by 1 digit.

I guess a better test would be to test for towgs84 parameters (either
in proj.4 string, or qgscoordinatesystem)


Compare the results of today's autotest (lucid i386 vs. amd64) using gdal 1.6.3

lucid i386: http://dash.orfeo-toolbox.org/testDetails.php?test=10064978&build=85452

XFAIL  : TestQgsCoordinateReferenceSystem::createFromESRIWkt()
expected failure with GDAL 1630 : test 0 PROJ.4 = [ +proj=utm +zone=48
+a=6377276.345 +b=6356075.413140239 +units=m +no_defs ] expecting [
+proj=utm +zone=48 +a=6377276.345 +b=6356075.41314024
+towgs84=198,881,317,0,0,0,0 +units=m +no_defs ]

lucid amd64: http://dash.orfeo-toolbox.org/testDetails.php?test=10066758&build=85457

XFAIL  : TestQgsCoordinateReferenceSystem::createFromESRIWkt()
expected failure with GDAL 1630 : test 0 PROJ.4 = [ +proj=utm +zone=48

+towgs84=198,881,317,0,0,0,0 +units=m +no_defs ]

Plus ubuntugis i386 failed because of the same precision issue,
whereas lucid-ubuntugis-amd64 passed

http://dash.orfeo-toolbox.org/testDetails.php?test=10066805&build=85462
