Hi Tanuj,<br>
<br>
I compare current libpng folder and previous one:<br>
1. You include a lot of files needed to build standalone library,
but not need in GDAL sources tree (like configure, CMakeLists.txt,
etc.). <br>
2. The makefile.vc removed and it seems to me the windows build will
fail in that case.<br>
3. There was a libpng_gdal.patch file, are you sure that this file
is not necessary?<br>
4. You included several files need for libpng unit testing, but not
needed by GDAL. According to GNUMakefile in png folder, it get all
*.c files from libpng folder, so we need minimum set of *.c and *.h
files there (but enough for VC building too).<br>
<br>
About python support - do you did sudo make install (Linux)? The
only building is not enough to have python bindings work (there is a
tick with PYTHONPATH, but not sure that it works. <br>

<div>Hello Dmitry,<br>
</div>
Sorry for the long delay, my exams had the better of
me, but now they're over :) .<br>
</div>
I have updated libpng 1.6.21 and i have created a pull
request after removing files from original libpng 1.6.21
that I think would not be required as a library in GDAL.<br>
</div>
All test on travis have been passed, and you can see the
pull request here : <a moz-do-not-send="true"
href="https://github.com/OSGeo/gdal/pull/108">https://github.com/OSGeo/gdal/pull/108</a><br>
<br>
</div>
As for building on desktop, I configured with python, but
the same issue of "ImportError: No module named osgeo
persists". I am trying to understand why this is happening,
and am working out how to get rid of this problem by reading
GDAL wiki.<br>
<br>

The error: ImportError: No module named osgeo <br>
is because you build gdal without python support (you need
python with developers headers). <br>
On Linux Linux this is done via such command:<br>
./configure --with-python ... <other config options><br>
<br>
On Windows it depends how you build. On Windows I launch
separate tests successfully but never try the whole tests
(run_all.py).<br>

<div>Now, as far as I could understand, it is
importing a file called "gdal.py" from a folder
called osgeo. I searched for it, and got its
path as "gdal/swig/python/osgeo, whereas the
autotest folder is separate.<br>
</div>
<div>So my guess is I have to somehow specify the

I replaced libpng

And then used
./configure and make
install on this test

which installed
successfully. I used
gdalinfo on a png

the libpng 1.6.21

it was OK, and it

I'd love to

</span> I think this
rather arguing
ticket as the bool

duplication

I think this ticket

is good for: 1.
building GDAL, 2.
Testing via TraviC
on GitHub. By the
way the libpng
version is 1.6.21 or
maybe higher.<br>
<br>
Anyhow, you have to
try to build gdal

Now, about the
GSoC idea, do
I need to know
JSON( or
GeoJSON, for
that matter)
to work on it?
I only ask
because the
idea lists
C/C++ as the
required
skills, but I
feel that
maybe this
work would
involve
knowing JSON
too...<br>
</div>

</span> Yes,
certainly. But JSON
are very simple.
Also GeoJSON spec.
