--- Comment #9 from reserv0@yahoo.com --- OK, I solved the issue with the DLLs: it was due to a bad packaging, because Wine 7.20 adds more DLLs (likely newly PE-converted *.so libraries), but its installation script places them in the wrong directory (/usr/lib/wine/[i386|x86_86]-unix/ instead of /usr/lib/wine/[i386|x86_86]-windows/), meaning the said DLLs are not found at runtime and weere causing more DLL loading failures. The misplaced DLLs are: apisetschema.dll, icmp.dll, lz32.dll, mferror.dll, msimsg.dll, normaliz.dll, security.dll, sfc.dll, shdoclc.dll, tzres.dll, usp10.dll, wmi.dll You might want to fix the install script for v7.21...
Anyway... Back to boost diriterator business !
I could test a viewer linked against boost v1.80 and, good news, it indeed seems to work just fine with Wine 7.20 now !
Problem solved, I guess. :-)
