[galib] Problems Building the Examples with MS Visual C++ 2010, Not Solved

Mon Jun 13 14:40:45 EDT 2011

Hello,

I posted the same message a few months ago but I had no answer.

I am sorry to do it but I will repost my question here hoping to find
somebody who solved the problem I have.

I use Windows XP (SP3) and I compile GAlib 2.4.7 (and the examples  
included) with MS Visual C++ 2008 (express ed.) successfully.
Yesterday, I decided to upgrade and try MS Visual C++ 2010 (express  
ed.) with both Windows XP and Windows Vista, but some errors came up...
I had no problems building the static library. The problems came up  
with example 1.
I will paste the build output here:

unresolved externals
========== Build: 1 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I have to mention that the same configuration in Windows Vista gave  
error LNK2001 insted of error LNK2019.
Also, for example 1 I set Project Properties > Linker > Input > Ignore  
specific library to MSVCRTD.lib;msvcprtd.lib.

Any ideas how to build the examples properly?
I read some previous posts about LNK2001 and LNK2019, but they didn't  
helped a lot.
Thank you in advance,
Kyriakos.
