[Gdal-dev] nad27 problem?

[Tom Parker]

Actually I just tried it again with gdalwarp instead of my code and get the
same error message.

gdalwarp -t_srs '+proj=utm +zone=14 data=WGS84' oklahoma_city-w.dem
okc-temp.tif

generates the same error so I'm hoping it's just a configuration problem.

I'd be happy to try other files and projections if you can point me at them.

Thanks

Tom -

Are you successfully reprojecting OTHER files, and only having a problem
with a specific zone 14 target, or are you failing to reproject
anything?

Hello,

I'm porting an application from windows to linux and have run into a
puzzling problem while attempting to project a USGS dem file to UTM zone
14.

I'm using the current gdal and proj from cvs on a fully patched redhat 9
system and have run configure, make and make install on both projects
with default arguments.

The problem is the projection routine is failing and giving me the error
message.

ERROR 1: failed to load NAD27-83 correction file ...
ERROR 1: failed to load NAD27-83 correction file ERROR 1: Reprojection
failed, err = -38, further errors will be suppressed on the transform
object.

I've tried a few ideas from searches of the mailing list:

- uncompressing the original files from the archive to make sure no
windows <=> linux silliness is happening.

- using gdalinfo to make sure the dem file is readable, everything looks
normal.

- setting PROJ_LIB=/usr/local/share/proj/

- adding printf statements to LoadProjLibrary in ogrct.cpp to make sure
the library was really loading, it is with no issues I can see.

I'm a bit stumped :(

Any ideas would be greatly appreciated.

Regards,
Tom
