[GRASS-user] Error Opening wxPython: No module named agw.customtreectrl

GRASS GRASS user
1

I'm new to GRASS, Python, wxPython, and the rest.

I'm running GRASS 6.4.1 on Win7 through MSYS.

When loading either Sample Project Location using the user1 mapset, I get
the following error after selecting "Start GRASS":

Unable to get current grographic extent. Force quitting wxGUI. Please run
manually g.region to fix the problem.

Reason: No module named agw.customtreectrl

Traceback (most recent call last):
File "c:/Program Files/GRASS 6.4.1/etc/wxpython/wxgui.py", line 54, in
<module>
import wx.lib.agw.customtreectrl as CT
ImportError: No module named agw.customtreectrl

Any help would be much appreciated. Thanks.

Matt

start GRASS in the text mode and type

g.region -p

does it fail?

Forgot to add the following part of the error:

It fails.

An error box says

The ordinal 284 could not be located in the dynamic link library
SSLEAY32.dll

Hi,

2011/6/9 matty18 <m.j.mccourt@gmail.com>:

File
"c:/osgeo4w/usr/src/grass641_release/dist.i686-pc-mingw32/etc/wxpython/g

problem with g.region. The most important message is

"""
Unable to get current grographic extent. Force quitting wxGUI. Please run
manually g.region to fix the problem.
"""

the rest is misleading...

Could it have anything to do with not having installed through the osgeo4w
package?

I saw this line in the error return that calls for layertree.py:

File
"c:/osgeo4w/usr/src/grass641_release/dist.i686-pc-mingw32/etc/wxpython/gui_modules/layertree.py",

SSLeay is the predecessor of OpenSSL. This often gets linked in via
libpq (PostgreSQL client library) which is linked in via GDAL.

"ordinal ... could not be located" indicates that the version of the
DLL which was found at run time isn't the same one which the program
or library was linked against.

Hi,

I also reported this problem Jan 13/14 2011 (subject: Error starting WinGrass 6.4.1 RC1), and below is a copy of what I wrote up about it and send to Martin Landa.

Note, this workaround to get winGrass to work requires a change to a library file in the Windows system directory. However the preferred option should be to have winGrass use it’s local library files not the Windows library files which seem to be incompatible with winGrass hence the error message matty18 is getting.

Sharon

A google of the error message turns up many hits indicating the problem is with the DLLs ssleay32.dll and libeay32.dll.

From reading this:
http://msdn.microsoft.com/en-us/library/ms682586%28v=vs.85%29.aspx
the DLL search order is operating system directories (including C:WINDOWS\system32) before the PATH environment variable. In my case, the system32 directory contained the files ssleay32.dll and libeay32.dll (no version ids) as well as the GRASS-64\extralib directory (ssleay32.dll and libeay32.dll v0.9.8.15)

As C:WINDOWS\system32 is searched first (before the PATH environment variable), the system32 DLL files are used.

I’ve copied/renamed ssleay32.dll and libeay32.dll in system32 then copied ssleay32.dll and libeay32.dll from the GRASS-64\extralib directory in system32. I then rebooted the PC.

WinGrass 6.4.1 RC1 now starts! I’ll progressively test the WinGrass 6.4.1 RC1 vector functionality I normally use and report any issues. I’ll also wait and see what programs fail due to changing dll files in the system32 directory.

The issue now is - what should be the correct way of WinGRASS 6.4 sourcing the correct DLLs? and what is the correct way of replacing the DLLs in the system32 directory?
