The message you got came from ROOT rather from the operating system itself.
Before trying to load DLL ROOT does check whether file with DLL is available and apply its own
"share library path" provided by ".rootrc file.
This is supplied by:
const char *TWinNTSystem::GetDynamicPath()
{ static const char *dynpath = 0;
if (dynpath == 0) {
dynpath = gEnv->GetValue("Root.DynamicPath", (char*)0);
if (dynpath == 0)
dynpath = StrDup(Form("%s;%s/bin;%s,", gProgPath,gRootDir,gSystem->Getenv("PATH")));
}
return dynpath;
}
This means ROOT doesn't use the system provided "PATH" if ".rootrc" file contains a defintion
of "Root.DynamicPath".
If that symbol is not defined then ROOT uses the "regular" approach, namely it looks up "PATH" .
I'd like to mention that makes sense for the first DLL only. If the loaded DLL has a reference to another
DLL the "PATH" variable is used anyway. This is because Windows ("bt default") tries to load ALL DLL
one needs while the UNIX loads the share library ordered ("by default")
- Could you check your ".rootrc" file ?
