Re: [Dovecot] compiling dovecot on aix gcc 3.3.2

29 Mar 2007

      Hello funkypunky drunky,
this is an example how the script rewrite the command line when the
dovecot-imap binary is being linked:

Makefile calls libtool with:
../../libtool --tag=CC --mode=link
/usr/local/src/mail/src/bin/dovecot-cc
-qlanglvl=ansi -g -export-dynamic -bexpall -brtl
-L/usr/local/lib -L/usr/local/lib -o imap
cmd-append.o cmd-capability.o  cmd-check.o
cmd-close.o cmd-copy.o  cmd-create.o cmd-delete.o
cmd-examine.o cmd-expunge.o  cmd-fetch.o cmd-idle.o
cmd-list.o  cmd-logout.o cmd-lsub.o  cmd-namespace.o
cmd-noop.o  cmd-rename.o cmd-search.o cmd-select.o  cmd-sort.o
cmd-status.o cmd-store.o  cmd-subscribe.o cmd-thread.o cmd-uid.o
cmd-unselect.o cmd-unsubscribe.o client.o commands.o
commands-util.o imap-expunge.o  imap-fetch.o imap-fetch-body.o
imap-messageset.o imap-search.o  imap-sort.o imap-sync.o
imap-thread.o  mail-storage-callbacks.o main.o  namespace.o
../lib-storage/register/libstorage-register.a
../../src/lib-storage/index/maildir/libstorage_maildir.a
../../src/lib-storage/index/mbox/libstorage_mbox.a
../../src/lib-storage/index/dbox/libstorage_dbox.a
../../src/lib-storage/index/libstorage_index.a
../../src/lib-index/libindex.a  ../lib-storage/libstorage.a

../lib-imap/libimap.a  ../lib-mail/libmail.a
../lib-dict/libdict.a  ../lib-charset/libcharset.a
../lib/liblib.a  ../lib/mountpoint.o  -liconv

libtool calls dovecot-cc with:
/usr/local/src/mail/src/bin/dovecot-cc
-qlanglvl=ansi -g -bexpall -brtl -o imap
cmd-append.o cmd-capability.o cmd-check.o
cmd-close.o cmd-copy.o cmd-create.o cmd-delete.o

cmd-status.o cmd-store.o cmd-subscribe.o cmd-thread.o cmd-uid.o
cmd-unselect.o cmd-unsubscribe.o client.o commands.o
commands-util.o imap-expunge.o imap-fetch.o imap-fetch-body.o
imap-messageset.o imap-search.o imap-sort.o imap-sync.o
imap-thread.o mail-storage-callbacks.o main.o namespace.o

../lib-imap/libimap.a ../lib-mail/libmail.a
../lib-dict/libdict.a ../lib-charset/libcharset.a
../lib/liblib.a -liconv

dovecot-cc calls /usr/bin/xlc with:
/usr/bin/xlc
-qlanglvl=ansi -g -bexpall -brtl -o imap
cmd-append.o cmd-capability.o cmd-check.o
cmd-close.o cmd-copy.o cmd-create.o cmd-delete.o

-bE:.libs/libmail.exp
-bE:.libs/libdict.exp
-bE:.libs/libcharset.exp
-bE:.libs/liblib.exp
-bE:.libs/libsql.exp

Notice the "-bE:..." lines. These lines are appended by dovecot-cc to
initialize all globale symbols defined in libraries used to link imap.
The .exp files are generate on the fly by dovecot-cc.
The Library ../lib-sql/libsql.a was also being inserted, because of
known dependencies.

Hello Ralf,
Ohh thanks for your reply and i start to understand what is going on. You
tell everything very well. It is amazing. After i read your mail, I
export a
variable
export LDFLAGS="-Wl,-brtl" and now i find shared object files (.so) in
their proper places after compilation. At first glance everything seems ok
but when i tried to start dovecot
Edlopen(/usr/local/lib/dovecot/imap/lib10_quota_plugin.so) failed: rtld:
0712-001 Symbol i_malloc was referenced
from module /usr/local/lib/dovecot/imap/lib10_quota_plugin.so(), but a
runtime definition
of the symbol was not found.

Additional errors occurred but are not reported.
Error: imap dump-capability process returned 89
This symbols are not found. Now i get happy that i see the same error
message as you but the thing that i cannot understand these .exp files. I
have these exp files in their places, and they are created by aix
linker. (I
am using aix linker. IBM doesnt advice using gnu linker
http://www-128.ibm.com/developerworks/aix/library/au-gnu.html)
./dovecot-1.0.rc28/src/plugins/acl/.libs/lib01_acl_plugin.exp
./dovecot-1.0.rc28/src/plugins/convert/.libs/lib20_convert_plugin.exp
./dovecot-1.0.rc28/src/plugins/quota/.libs/lib10_quota_plugin.exp
./dovecot-1.0.rc28/src/plugins/imap-quota/.libs/lib11_imap_quota_plugin.exp
./dovecot-1.0.rc28
/src/plugins/lazy-expunge/.libs/lib02_lazy_expunge_plugin.exp
./dovecot-1.0.rc28/src/plugins/mail-log/.libs/lib20_mail_log_plugin.exp
./dovecot-1.0.rc28/src/plugins/trash/.libs/lib11_trash_plugin.exp
Do u mean that i have to point these exp files with linker flag -bexpall .
From your script i can not understand. Maybe you can give an example with
export LDFLAGS="bexpall bla bla"
Thanx and best regards.
