Linker error : Not a valid library (invalid magic number .....)

[sanjai]

Hi,
I???m in the process of compiling and linking our application with some third party libraries. During the linking phase I???m getting error below.
libsslc.a: Not a valid library (invalid magic number Possibly a 64-bit PA archive library (Mismatched ABI)
I???m compiling and linking with the option +DA2.0
Platform I???m using is
HP-UX 11.11 and the aCC version is A.03.33.
When I use the file command against ???libsslc.a??? it gives ???archive file??? however when I use the same command to check other archive files (which links properly) from the same vendor, it gives
"archive file -PA-RISC2.0 relocatable library"
Does any one have any idea on this ?

The very first thing that I would check is that
your 3rd-party library is even an HP-UX library. The most probable killer is that you are attempting to link 32-bit and 64-bit code - and that dog won't hunt.

Thanks for reply. They are compiled for HP-UX on 64 bit mode.

Yes but it appears that your 3rd party library is not HP - or at least not PA-RISC - it might be Itanium. You really need to make sure about your 3rd-party library.
