[Gdal-dev] Problems Linking with Stubs in the precompiled downloadable Win32 Binaries.

Louis,
I'm not sure about this, but it may be the order in which your vc++
platform sdk's are linked into your app. I've had this problem with
other apps before. You need to have them in the right order or you will
get this problem. Goto tools->options->projects->vc++ directories and
they should be linked in somewhat the following order:
$(VCInstallDir)lib
$(VCInstallDir)atlmfc\lib
$(VCInstallDir)PlatformSDK\lib\prerelease
$(VCInstallDir)PlatformSDK\lib
$(FrameworkSDKDir)lib
Although this will be machine independent depending on what sdk's you
have installed.
Just a thought...
Martin

Sorry I'm bothering you so much with this Frank -
I tried compiling GDAL from scratch but I got linking problems again.
These are my woes -

I vainly tried removing the MSVCRT and LIBC default libs by adding
/NODEFAULTLIB:LIBC and /NODEFAULTLIB:MSVCRT to LINKER_FLAGS in nmake.opt
- but I guess you can imagine how many unresolved symbols I got then.
Anyway, I'm using VC6 and I was wondering if that would cause any
problems... I noticed your precompiled binaries specifically look for
MSVCRT71.dll
I don't want to whine 'cause I really hate whiners, but I would really
appreciate it if you could direct me to a site where I can download
precompiled WIN32 Static Libs for GDAL and OGR. Or put one up if there
aren't any - actually any help would be dearly appreciated!
Thanks in advance,
Louis.

Fo Sheezy -
This is a simplified version of the code - note that I'm using a MapInfo
Data Source, a directory with several .TAB, .DAT, .MAP etc files (so in
GDAL
talk: a couple 'o Layers).
bool cVectorLoader::loadOGRVector(char* sVectorMap)
{
//DataSet
OGRDataSource* poDataSet = (OGRDataSource*)
OGRSFDriverRegistrar::Open(sVectorMap, false);
if (poDataSet == NULL)
{
return false;
}
const char* sName = poDataSet->GetName();
int iNrOfLayers = poDataSet->GetLayerCount();
cout << endl << "<OGR> Report for Vector Dataset " << sName << endl;
cout << "Dataset has " << iNrOfLayers << " layer(s)." << endl;
//Layers
for (int i=0; i < iNrOfLayers; i++)
{
cout << "For layer " << i+1 << endl;
OGRLayer* poLayer = (OGRLayer*) poDataSet->GetLayer(i);
if (poLayer != NULL)
{
//Features
int iNrOfFeatures = poLayer->GetFeatureCount(true);
OGRFeature* poFeature = (OGRFeature*) poLayer->GetNextFeature();
cout << "Layer has " << iNrOfFeatures << " features" << endl;
int j=1;
while (poFeature != NULL)
{
//Style
cout << "Feature " << j << " with ID " << poFeature->GetFID()
<< " and Style String " << poFeature->GetStyleString () <<
endl;
OGRStyleTable oStyleTable;
OGRStyleTool* poStyleTool;
OGRStyleMgr* poStyleMgr = new OGRStyleMgr(&oStyleTable);
poStyleMgr->GetStyleString(poFeature);
for (int k=0; poStyleMgr->GetPartCount(); k++)
{
poStyleTool = poStyleMgr->GetPart(k);
switch(poStyleTool->GetType())
{
case OGRSTCNone: cout << "Style = None" << endl;
break;
case OGRSTCPen: cout << "Style = Pen" << endl;
break;
case OGRSTCBrush: cout << "Style = Brush" << endl;
break;
case OGRSTCSymbol: cout << "Style = Symbol" << endl;
break;
case OGRSTCLabel: cout << "Style = Label" << endl;
break;
}
}
...
poFeature = (OGRFeature*) poLayer->GetNextFeature();
j++;
}
}
}
cout << endl << "<OGR> End of Report" << endl;
//Clean up
delete poDataSet;
//Function completed successfully
return true;
}
Compilation is all good. When linking I get ze following errors.

I'm using gdal_i.lib => gdal12.dll, the ones from the downloadable
binaries. I should add that for the past three yrs I've been a Java Boy
and for the last two weeks I've been brushing up on my C skills, which I
haven't used since my Varsity days. I could just be doing something
stupid. However, everything links fine when I comment out the Style Tool
thingies.
BTW Frank - thanks for the great library!
Louis.

Louis,
There are indeed some issues with linking against the DLL version of OGR
and using some of the style related classes. I am a bit uncertain what
the exact problem is, but if you can list your link errors, and provide
a smallish example program that demonstrates the problem I will try and
fix it. I have run into a similar problem with MapServer but never
succeeded in resolve it.
Note, the problem can be worked around by linking against static
versions of OGR but if possible i would prefer to just fix the base
problem.
Best regards,
