Hi: New to mutt and to this list--please let me know if I make mistakes. My question: is the following due to a configuration problem on my system, or is it a problem with the mutt build? The command line $ ./configure --enable-imap --with-gss=~/tmp/krb5_compile/krb5-1.2.1/src fails with "GSSAPI support not found." In config.log I see: configure:4303: gcc -o conftest -g -O2 -I/usr/include/ncurses -I/home/leon/tmp/krb5_compile/krb5-1.2.1/src/include -L/home/leon/tmp/krb5_compile/krb5-1.2.1/src/lib conftest.c -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err 1>&5 /home/leon/tmp/krb5_compile/krb5-1.2.1/src/lib/libkrb5.a(hst_realm.o): In function `krb5_try_realm_txt_rr': hst_realm.o(.text+0x12a): undefined reference to `res_search' hst_realm.o(.text+0x1de): undefined reference to `dn_expand' hst_realm.o(.text+0x27a): undefined reference to `dn_expand' /home/leon/tmp/krb5_compile/krb5-1.2.1/src/lib/libkrb5.a(locate_kdc.o): In function `krb5_locate_srv_dns': locate_kdc.o(.text+0x8c2): undefined reference to `res_search' locate_kdc.o(.text+0x96b): undefined reference to `dn_expand' locate_kdc.o(.text+0x9fa): undefined reference to `dn_expand' locate_kdc.o(.text+0xc57): undefined reference to `dn_expand' I was able to work around this by making the following change: $ diff ~/tmp/configure.original configure 4289c4289 < LIBS="-lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err $LIBS" --- > LIBS="-lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lresolv $LIBS" I then run make, which fails at the end; I make another change: $ diff ~/tmp/Makefile.original Makefile 88c88 < MUTTLIBS = -lncurses -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err --- > MUTTLIBS = -lncurses -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lresolv and run "make" again, successfully. (Great software--thanks!) The result is: $ mutt -version Mutt 1.2.4i (2000-07-07) System: Linux 2.2.14-5.0 [using ncurses 4.0] Compile options: -DOMAIN -DEBUG -HOMESPOOL +USE_SETGID +USE_DOTLOCK +USE_FCNTL -USE_FLOCK +USE_IMAP +USE_GSS +USE_SSL -USE_POP -HAVE_REGCOMP +USE_GNU_REGEX +HAVE_COLOR +HAVE_PGP -BUFFY_SIZE -EXACT_ADDRESS +ENABLE_NLS SENDMAIL="/usr/sbin/sendmail" MAILPATH="/var/spool/mail" SHAREDIR="/usr/local/share/mutt" SYSCONFDIR="/usr/local/etc" ISPELL="/usr/bin/ispell" (I also had ssl and regex turned on for the actual build.)
