--- Comment #4 from Hans Leidekker hans@meelstraat.net --- (In reply to Olivier F. R. Dierick from comment #3)
I tried LD_PRELOAD="/usr/local/lib/libpcap.so" wine wpcap_tests-stripped.exe
It says "ERROR: ld.so: object '/usr/local/lib/libpcap.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.".
So now I need to find how to have 32-bit libpcap library along the 64-bit one.
Note that running the 32-bit test will require the new wow64 setup. Alternatively you could try the 64-bit test.
