[ggt-devel] Continue about the pygmtl problem.

[Ming J. <ji...@gm...>]

Sorry for opening a new thread of the same problem, I just subscribe this
email list.

I have set the path to boost-python in system path.
That is set the C:\Program Files\boost\boost_1_34_0\lib  to %PATH%,
and when using scons to build the pygmtl, the scons can find the correct
boost_python-vc80-mt-gd-1_34.dll  under this path.

One thing that maybe helpful is that, when I use scons to build pygmtl, I
get the following warning for all the files.

C:\Program Files\boost\boost_1_34_0\boost/utility/enable_if.hpp : warning
C4819:
 The file contains a character that cannot be represented in the current
code pa
ge (936). Save the file in Unicode format to prevent data loss


Is that related to my problem when issue "import gmtl" in python:
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import gmtl
ImportError: DLL load failed: A dynamic link library (DLL) initialization
routine failed.

Another thing is that, right before the ImportError happens, there is a
window pop up, and saying:

Runtime Error!
Program: C:\Program Files\Python25\pythonw.exe

R6034
An application has made an attempt to load the C runtime library
incorrectly.

Thanks a lot for your help.

It sounds as though you are mixing release and debug runtimes. According =

[Ming J. <ji...@gm...>]

Thank you for your detailed information.

I am sorry for sending you wrong information. As I checked my building steps
again, I find the scon command will use the
Using 'C:\Program
Files\boost\boost_1_34_1\lib\boost_python-vc80-mt-1_34_1.dll'

Not the debug version of dll. And this dll can be found.
So my problem is probably not the debug/release problem.

Also, is the unicode warning happened for other computers? it seems like a
boost problem. But I do not know how to configure it.

Thanks.

I think that the problem is that the DLL manifest for gmtl.pyd is not being
found by the runtime loader. The PyGMTL build does not embed the manifest in
the DLL when using Visual C++ 8.0. This can be corrected. Build PyGMTL again
using the attached SConstruct file as a replacement for the one in your GMTL
source tree. (I assume that you are using GMTL 0.5.4.) You do not need to
clean your build tree if you still have it. The change I made only modifies
how gmtl.pyd is linked, so only the last step of the build needs to be
performed.

I don't know what the Unicode warning is about, but it seems like a Boost
problem. I don't see any non-ANSI characters in boost/utility/enable_if.hpp
after skimming it. It's too bad that the compiler does not say what line
contains the problematic character(s).

[Ming J. <ji...@gm...>]

That's great!
I tried with the new SConstruct file, it really works.

Thanks a lot!

ps: in the previous email. I did not delete the email history, which cause
the size exceed the limit. sorry about that.

Thanks for testing the change. It has been committed to the repository.
