Hi Tanuj,<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>I could not understand what that means. I guess this is
important because when I tried the commands given on that
page, I got the following error :<br>
<br>
</div>
<div>File "./run_all.py", line 37, in <module></div>
<div>import gdaltest</div>
<div>File"pymod/gdaltest.py", line 37, in <module></div>
<div>from osgeo import gdal</div>
<div>ImportError: No module named osgeo<br>
<br>
<br>
</div>
<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 path of
"gdal.py"<br>
</div>
<div><br>
</div>
<div>Could you or anyone please guide me on how to proceed with
this?<br>
<br>

I replaced libpng folder of gdal
(frmts/png/libpng) with libpng
1.6.21. And then used ./configure
and make install on this test
version of gdal, which installed
successfully. I used gdalinfo on a
png file provided with the libpng
1.6.21 source, to check if it was
OK, and it successfully gave the
png file details.<br>

</span> You need to see the previous version.
Some files not needed (i.e. configures and so
on, which already comes from gdal, but legal
notice must be present (license, autors, etc.)
). Don't hesitate to ask in list.

<div>Yes, I have
looked at the
ideas list, and I
am currently
reading up on idea
no. 16, which is,
implementing
support for the
proposed standard
for incrementally
parseable GeoJSON
data.<br>
<br>

that maybe I could

after I've studied
about the GSoC idea,
which is not really a
bug, but an
enhancement. But if
there are any other
tickets that you or
anyone else would like
to recommend me to
work on, I'd love to
see them too!<br>
</div>
</div>
</div>
</div>

</span> I think this rather
arguing ticket as the bool is not
exist in plain C, and duplication
functions seems to me not good
idea.<br>
I think this ticket <a

target="_blank"><a class="moz-txt-link-freetext" href="https://trac.osgeo.org/gdal/ticket/6185">https://trac.osgeo.org/gdal/ticket/6185</a></a>
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 and test it with autotests
from <span lang="en"><span>appropriate</span></span>
folder. <span>
<blockquote type="cite">
<div dir="ltr">

<div><br>
</div>
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>
</div>
</div>

</span> Yes, certainly. But JSON
are very simple. Also GeoJSON
spec. can be found here <a

Hi, Tanuj<br>
<br>
I'll look for opened
tickets for you, or
maybe others can
recommend some for
you.<br>
<br>
By the way, do you
see the idea list (<a
moz-do-not-send="true"
href="https://trac.osgeo.org/gdal/wiki/SummerOfCode#a2016IdeasList"
target="_blank"><a class="moz-txt-link-freetext" href="https://trac.osgeo.org/gdal/wiki/SummerOfCode#a2016IdeasList">https://trac.osgeo.org/gdal/wiki/SummerOfCode#a2016IdeasList</a></a>)?
<br>
The ideas are not
ranked yet - the
numbers in the list
- are only in order.
<br>
This is a task for
us to rank the
ideas. <br>
But, have you some
preferable idea (or
ideas) for GSoC from
this list or maybe
you have got own?<br>

I am

GSoC this

Currently, I

on the GDAL
Summer of Code
ideas list. I
know C++ and
C, and I have
some

Could the
