Thank you so much! At the moment it doesn't work to me, even specifing the --with-gdal flag in configure launch. I'm not an autotools expert, but this is a very good starting point. If I have time to study and modify your code I will let you know. Regards.

I did post nothing because I have to better check what is going on with my project. No time for doing that right now. I launched my configure script in the same way, but probably something is missing in my configure.ac. Could you please post your configure.ac?

[gdal-dev] Autoconf macro for gdal-config
Compiling my gdal programs with the autotools, I would like to use gdal-config in my configure.ac file, in order to manage gdal path on different systems. The same things is made for example with the PKG_CHECK_MODULES macro for libraries which support pkg-config. Is there a pre built macro to do the same thing? Or should I write a new macro? Examples and hints on that would be really appreciated... -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Autoconf-macro-for-gdal-config-tp6907599p6907599.html Sent from the GDAL - Dev mailing list archive at Nabble.com. ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
[gdal-dev] Re: GDAL link problem on MS Visual Express 2010
I repost it because in the previous version, raw text has disappeared from
this message mail.

I've followed instruction here
http://trac.osgeo.org/gdal/wiki/BuildingOnWindows to build gdal on Windows.
Now I have my installation under C:\ with this directory tree:
C:\
GDAL-1.8.1
bin
lib
data
include
html
I'm using Microsoft Visual C++ 2010, but with this small example, linking
fails:
#include stdio.h
#include gdal.h
int main() { GDALAllRegister(); return 0; }
-- Build started: Project: gdal_test, Configuration: Debug Win32 --
gdal_test.c
gdal_test.obj : error LNK2019: unresolved external symbol _GDALAllRegister@0
referenced in function _main

2010\Projects\gdal_test\Debug\gdal_test.exe : fatal error LNK1120: 1
unresolved externals
== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==
But I think to have set correctly include and lib paths into my project; in
window Property Pages -- Configuration Properties -- VC++ Directories I
have set:
Executable Directories -- C:\GDAL-1.8.1\bin;$(ExecutablePath)
Include Directories -- C:\GDAL-1.8.1\include;$(IncludePath)
Library Directories -- C:\GDAL-1.8.1\lib;$(LibraryPath)
So, where am I wrong?

[gdal-dev] Re: Mask and GEOTiff
I think gdal merge is the easier way. But with a command like this: gdal_merge.py -of GTiff -separate -o cropped.tif orig.tif mask.tif I obtainn a GEOTiff with two bands: the first is the original image and the second is the mask. This is not what I want. I would like to obtain a single band GEOTiff with visible only the pixels of original image filtered by the mask. Is that possible with a further passage or with another tool? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Mask-and-GEOTiff-tp6312284p6312590.html Sent from the GDAL - Dev mailing list archive at Nabble.com. ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

[gdal-dev] Re: Catch a GDALOpen exception
Ok. So if I have well understood the most safe thing to do is the following:
myDataset = (GDALDataset *) GDALOpen( myFile.tif, GA_ReadOnly );
if(myDataset == NULL )
{
return 14;
}
Indeed it works and I obtain 14 as returning value of my program...

[gdal-dev] Catch a GDALOpen exception
I have this incorrect code:
try
{
myDataset = (GDALDataset *) GDALOpen( myimg, GA_ReadOnly );
}
catch(int n)
{
cout File not existent! endl;
return 14;
}
I would like to catch the exception thrown by GDALOpen if the file is not
existent and manage it in a way to return an integer that I want and not the
default 134.
How can I achieve this?
Thanks in advance!

[gdal-dev] gdal_translate -mo option
Hi everyone. gdal_translate -mo VALUE=1234 input.tif output.tif works fine. But what if I have to insert 2 or more metadata values? gdal_translate -mo VALUE_1=1234 -mo VALUE_2=5678 input.tif output.tif It doesn't work. Is there any wildcard to use into -mo string to insert multiple values? For example gdal_translate -mo VALUE_1=1234\nVALUE_2=5678 input.tif output.tif Also this doesn't work.

What is the file without georeferentiation? @Ivan Lucena Unfortunately I don't have python support in my GDAL installation and I cannot recompile it. Using gdal_translate is ok, but is there another way to avoid rewriting on disk the image (which is quite big)?
