[Gdal-dev] Re: ruby bindings proj4 stangeness

[Shoaib Burq]

Hi Charlie

Sorry about the delayed response. The osr_warp.cxxx does contain the
import/export_to_proj4 definitions.

just did a hand compile of gdal-cvs on my laptop using --with-ruby
config option and it works. While on the problem server i used an
ebuild with a gdal-ruby patch that just modifies the RubyMakefile.mk
to add ${RUBY_MODULES} to the install target -- something bad happens
without it -- if my memory serves me correctly it couldn't find
gdal.o. I am now thinking the problem maybe with my ebuild. I am
investigating this. will keep you posted.

regards
Shoaib
