What am I missing??

I’ll admit that I’m lost here.  I’m trying to build the latest GPSBabel from source using Microsoft C++ 2008 Express Edition and after adding the Windows DDK and getting everything to compile; I’m getting the following link errors?  It’s probably something easy but I don’t know enough to understand it.  These are the errors I’m getting while linking:

 

Linking...

alan.obj : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance

vecs.obj : error LNK2001: unresolved external symbol _skytraq_vecs

vecs.obj : error LNK2001: unresolved external symbol _pocketfms_wp_vecs

vecs.obj : error LNK2001: unresolved external symbol _enigma_vecs

vecs.obj : error LNK2001: unresolved external symbol _vpl_vecs

.\Release/GPSBabel.exe : fatal error LNK1120: 4 unresolved externals

Build log was saved at "file://i:\gpsbabel\msvc\Release\BuildLog.htm"

GPSBabel - 5 error(s), 0 warning(s)

========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========

 

Any help would be appreciated.  

 

Thanks in advance.

Those formats were added very late in 1.3.6 and didn't make it to the msvc project files.  Just add the .c files that provide skytraq, vpl, enigma, etc.

Is skytraq.c part of the visual studio project file? Looks like it's
missing thus doesn't get linked in.

Robert Lipe: my skytraq patch touches the Makefile only. I dont use
Windows anymore so I wasn't able to make Win-specific changes (if there
are any?)

Regards
Mathias

It, like the others were added to the MSVC7 project files after the 1.3.6 release.

I'm sure we've added _other_ files since then that also needed to be added.   The reality is that we just don't have any active developers that use MSVC so the project files tend to decay.
