hi, there!
libtool silently adds -lc when linking libraries. As a result
all the programs which a linked with -pthread and with library built with
libtool is linked against both libc and libc_r.
This is a program which is linked with -pthread and with libodbc.so.1
(unixODBC), both libtool and unixODBC are built from ports:
lark:~/plesk2/src/plesk$ldd foo
foo:
libmd.so.2 => /usr/lib/libmd.so.2 (0x2809a000)
libodbc++.so.4 => /usr/local/lib/libodbc++.so.4 (0x2809e000)
libACE.so => /home/fjoe/ACE_wrappers/ace/libACE.so (0x28148000)
libTAO.so => /home/fjoe/ACE_wrappers/ace/libTAO.so (0x2835f000)
libm.so.2 => /usr/lib/libm.so.2 (0x28a68000)
libc_r.so.4 => /usr/lib/libc_r.so.4 (0x28a83000)
libodbc.so.1 => /usr/local/lib/libodbc.so.1 (0x28b19000)
libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x28b49000)
libc.so.3 => /usr/lib/libc.so.3 (0x28b5e000)
Another question (maybe not related to -ports) is how to link
program with libtool against static library even if shared libraries
are present (I need to link against /usr/lib/libdescrypt.a instead of
shared one to ensure that I will always have DES crypt).
Using /usr/lib/libdescrypt.a instead of -lcrypt does not help --
libtool complains about using non-libtool object.
