Thank you for reply.

I know about -L and -l flags

construction 

-L../../../openexr-1.4.0/IlmImf -llibIlmImf.a

does not works because -shared flag used and I'll get followed error during compiling

/usr/bin/ld: cannot find -llibIlmImf.a

collect2: ld returned 1 exit status

If I'll use constuction

-L../../../openexr-1.4.0/IlmImf -llibIlmImf

library will linked as shared

Problem that I need static link OpenEXR and as shared link libstdc++. 

It's common problem and I don't know how to do it.

Or is it possible to link libstdc++ as static?
