Re: [classad-users] Linker Problems

[Ole Weidner <oweidner@xxxxxxxxxxx>]

Hey,

I use these flags: -DWANT_NAMESPACES -DWANT_CLASSAD_NAMESPACE but if I  
us -lclassad_ns as you're suggesting, I get the following error:
ld: library not found for -lclassad_ns

Which sounds right to me, since there's no libclassad_ns.dylib in the  
installation directory. Are there any configure flags that control the  
whole namespace stuff when I build libclassad?
Thanks,
Ole
