[gdal-dev] gdalbuildvrt files not recognized

[Simon Shak]

if I try to use wildcard:
gdalbuildvrt output.vrt input/*.ecw
I get the error:
ERROR 4: `input/*.ecw' does not exist in the file system, and is not
recognized as a supported dataset name.
it doesn't matter if I use / or \ or * or *.ecw or *.*.

My expectation based on the documentation and previous usage is that you
can keep adding to a vrt by subsequent commands with the same vrt file
unless you pass in the -overwrite option.

However, your suggestion to check the filelist.txt file has found the
error.  Somehow a trailing space was before the CRLF and caused it to not
recognize the file.
Thanks for the quick help.
