[osg-users] GLSL plugin static linking issue (recent master branch)

[Andrew Poltavets]

Hi,

First of all I pretty new to engine thus I may sound silly.

In my case OSG tends to load glsl dynamic library despite I wrote
USE_OSGPLUGIN(glsl) and linked with libosgdb_glsld.a.

As I had stuck with this I decided to get to the debug. So please let me show what I have found so far and what feels suspiciosly for me:
In function 
Code:
ReaderWriter::ReadResult Registry::readImplementation(const ReadFunctor& readFunctor,Options::CacheHintOptions cacheHint)

 

value of 
Code:
useObjectCache= options ? (options->getObjectCacheHint()&cacheHint)!=0: false;


becomes equal true for FreeType plugin but false for GLSL plugin due to missed options in very first debug frame for GLSL plugin:


Code:
inline osg::ref_ptr<osg::Shader> readRefShaderFileWithFallback(osg::Shader::Type type, const std::string& filename, const char* fallback)
{
   return osgDB::readRefShaderFileWithFallback(type, filename, Registry::instance()->getOptions(), fallback);
}



If I got it right having useObjectCache as false ends up with search of dynamic library.

That could be incorrect observations... So if I wrong here - could somebody please help me getting GLSL thing to work properly?


Configuration:
Recent `master`: bd50af117bed340b14b5bf13da6a8efe893f4ce7
