System: NetBSD cixy.dial.pasteur.fr 4.99.18 NetBSD 4.99.18 (CIXY_DEVEL) #75: Thu Apr 26 19:09:44 CEST 2007  njoly@cixy.dial.pasteur.fr:/local/src/NetBSD/obj/i386/sys/arch/i386/compile/CIXY_DEVEL i386

Machine: i386
>Description:
It seems that recent CHECK_ALT_xxx() removal broke uvscan running under
compat_linux on i386.

njoly@cixy [~]> pkg_info | grep uvscan
uvscan-4.40nb1      Evaluation version of a DOS/Windows file virus scanner

uvscan: error while loading shared libraries: liblnxfv.so.4: cannot open shared object file: No such file or directory

   240      1 uvscan   CALL  open(0xbfbfdef0,0,0xbbbf8f61)

   240      1 uvscan   RET   open -1 errno -2 No such file or directory

The needed file exists, and looks good to me :

njoly@cixy [~]> ls -l /emul/linux/usr/local/lib/liblnxfv.so.4 
lrwxr-xr-x  1 root  wheel  43 Apr 26 18:57 /emul/linux/usr/local/lib/liblnxfv.so.4 -> ../../../../../libexec/uvscan/liblnxfv.so.4
njoly@cixy [~]> ls -lL /emul/linux/usr/local/lib/liblnxfv.so.4
-r-xr-xr-x  1 root  wheel  2909612 Apr 26 18:57 /emul/linux/usr/local/lib/liblnxfv.so.4

Booting an older kernel make it works.
