May 23, 2011 Building DMD on Linux with Windows Domain Logins | ||||
|---|---|---|---|---|
| ||||
 | Funny thing happened today. I tried building DMD from source, and got this: dmd: libelf.c:171: void OmToHeader(Header*, ObjModule*): Assertion `len <= 6' failed. Digging around, and it appears that my user ID can only be 6 characters long. Doh! I happen to be on a RHEL 6 workstation that can authenticate users via a Windows Domain Controller (using samba + winbind). My smb.conf looks has these two lines: idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 Which is to say "If a uid or gid appears on the system, use winbind to resolve to a name". On my machine, my user looks like this: [kai.meyer@kai-rhel6 BUILD]$ id uid=16777216(kai.meyer) gid=16777221(domain users) groups=16777221(domain users),16777223(SENSORED),16777224(SENSORED),16777225(SENSORED),16777226(SENSORED) That's right. My UID is 8 characters long. Are we interested in accommodating UID and GID's that are this big? -Kai Meyer | |||

On the bright side, the rpm builds on RHEL6 with no problems if I build it with a UID/GID of 500 :)
