Those comes from the fact that I compile in an uclibc chroot. I can work around the messages by setting KSRC=/usr/src/linux.
The problem has to do with my gcc-3.4.6 compiler version and not uclibc. First is set_scn_flag(x) defined: #if __BYTE_ORDER == __LITTLE_ENDIAN #define set_scn_flag(x) \ { \ x = (x & 0x55555555) << 1 | (x & 0xaaaaaaaa) >> 1; \ x = (x & 0x33333333) << 2 | (x & 0xcccccccc) >> 2; \ x = (x & 0x0f0f0f0f) << 4 | (x & 0xf0f0f0f0) >> 4; \ x = (x & 0x00ff00ff) << 8 | (x & 0xff00ff00) >> 8; \ x = (x & 0x0000ffff) << 16 | (x & 0xffff0000) >> 16; \ } #else #define set_scn_flag(x) (x) #endif Later this code appears: scn_flags = ISNS_SCN_FLAG_INITIATOR | ISNS_SCN_FLAG_OBJECT_REMOVE | ISNS_SCN_FLAG_OBJECT_ADDED | ISNS_SCN_FLAG_OBJECT_UPDATED; scn_flags = htonl(set_scn_flag(scn_flags)); If i understand that correctly gcc-3.4.6 will expand it as: scn_flags = htonl( { scn_flags = (scn_flags & 0x55555555) << 1 | ... ; ... } ); which is invaild.

(In reply to comment #5) Sorry for the mess. Not using uclibc...
please try changing the macro to read: #define set_scn_flag(x) ({ .... }) in other words, just add the parens before/after the braces
hmm it'll fail to build even with gcc-4.x if you use -O0 added the fix i proposed to cvs http://sources.gentoo.org/sys-block/iscsitarget/iscsitarget-0.4.15-r1.ebuild?r1=1.2&r2=1.3 http://sources.gentoo.org/sys-block/iscsitarget/files/iscsitarget-0.4.15-isns-set-scn-flag.patch?rev=1.1
