Bottom line: Pthread symbols must always be resolved through the actual=20 program. Make sure the program that uses wxruby is linked with -pthread as= =20 well. =2D-=20 ,_, | Michael Nottebrock | lofi@freebsd.org (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org --nextPart1230678.1BTZnkYqzq Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBB2WaIXhc68WspdLARAvYYAKCnBUNrHgJVA6qusg35lq3VTUeabACePa9O a/9fGG1J1wX7V0FpLJV2Vj8= =c2Xa -----END PGP SIGNATURE----- --nextPart1230678.1BTZnkYqzq--
