--- Comment #4 from Ravi <ravi.kappiy...@cd-adapco.com> --- This does seem to be an issue with any ABI version older than the newest (11, I think), which appears to have a different name mangling scheme than any of ABI versions 6-10, all of which fail when attempting to link against an object file compiled against the latest ABI. This was not the case with GNU 6.2 which used ABI version 10, which appears to be compatible with ABI version 6. Unfortunately, due to other constraints we are forced to use ABI version 6 for certain aspects of the code - are there any known work-arounds to getting ABI version 11 to link against code compiled with an older ABI version?
