[El] Trying to build gdal with ECW support on SL 6.0

[Micha Silver]

Hi Volker:

Thanks for responding. I'm not there yet.

I put the 1.7.3 patch in place (into the 1.7.2 SOURCE directory) and 
altered the spec file to apply it, and it was applied:


[micha at MS-SL6 rpmbuild]$ grep -r Xcompiler BUILD
BUILD/gdal-1.7.2-fedora/swig/ruby/RubyMakefile.mk.xcompiler:LDFLAGS += 
-Xcompiler -shared -L$(RUBY_LIB_DIR)
BUILD/gdal-1.7.2-fedora/ltmain.sh:    -Xcompiler)
BUILD/gdal-1.7.2-fedora/ltmain.sh:      -Xcompiler)
BUILD/gdal-1.7.2-fedora/libtool:    -Xcompiler)
BUILD/gdal-1.7.2-fedora/libtool:      -Xcompiler)


The -Xcompiler flag appears only in the backup RubyMakfile, not in 
RubyMakefile.mk itself as in the patch .


But I still get these errors:

VALUE)':

Maybe I should take this question to the EPEL maillist. I wonder how the 
packaged gdal.1.7.2 was built??

Micha
