Configuring it with ECLIPSE PyDev

[farrukhqayum]

I wasn't able to configure pyproj with ECLIPSE. However, I was able to do it with standalone Py IDE.

Did any one try? What do I have to do it to properly run it in Eclipse.
I did properly add the source folders & eggs in pythonpath. I always get this error:

console: Failed to install '': java.nio.charset.UnsupportedCharsetException: cp0.
Traceback (most recent call last):

It is choking on this line, from pyproj import _proj. This is where pyproj imports the Cython portion (which in C code interfaces with the C library PROJ.4).

I did properly add the source folders & eggs in pythonpath.

If you install with pip, You have less to worry about those types of details because it will compile it for you. Run C:\..> pip install pyproj

Thanks Micah for a swift reply.

I did this and the standalone Python works fine. It is only the ECLIPSE issue. It does not recognize the pyproj path.

I don't have ECLIPSE installed. I've got two questions that *might* help.

What is the value of the variable pyproj.pyproj_datadir ?

Where is PROJ.4 installed on your box?

[farrukhqayum]

Following your e-mail I used the pip installation without setting the PROJ.4. So, I assume it is using the src. Thus, I should not link it to the environment variable PROJ_DIR. With this installation, Python IDLE works fine as shown in the previous attachmen (bottom left). Eclipse does not!

However, I also have a standalone installation of PROJ.4 located under:

C:\Python27\Lib\site-packages\proj.4

The datadir file has the following contents.

if 'PROJ_DIR' in os.environ:
pyproj_datadir = os.environ['PROJ_DIR']
else:
pyproj_datadir = os.sep.join([os.path.dirname(file), 'data'])

Eclipse setup is like this:

Resolution:

The main problem was the compilation of the PROJ.4. It was using ./configure in the cygwin.

Then I ran the preinstalled MSVC 8 command prompt via the start menu and ran nmake. It created the share/ folder in the installation path (set by editing the nmake*.opt file (INSTDIR = c:\Proj). After this, the eggs of pyproj were correctly build by running the pyproj (using python setup.py pyproj).

I have seen many users suffered in the Eclipse to properly do this.

I'm glad you figure it out. Thanks for sharing the solution.
