Both beta4 and 5 configure command was (I also used, to test only,
./configure && make in beta4, same problem)

./configure '--prefix=/usr/local' '--disable-debug' '--with-gnu-ld' '--with-etcdir=/usr/local/etc/silc' '--with-docdir=/usr/doc/silc-client-1.1-beta5' '--with-pthreads' '--with-helpdir=/usr/local/share/silc/help' '--with-perl=yes' '--with-perl-lib=site' '--with-simdir=/usr/local/share/silc/modules'



Link command was:

gcc -g -O2 -Wall -o silc gui-entry.o gui-expandos.o gui-printtext.o gui-readline.o gui-windows.o lastlog.o mainwindows.o mainwindow-activity.o mainwindows-layout.o statusbar.o statusbar-config.o statusbar-items.o term.o term-dummy.o tparm.o term-terminfo.o terminfo-core.o textbuffer.o textbuffer-commands.o textbuffer-reformat.o textbuffer-view.o silc.o module-formats.o -Wl,-E -Wl,--export-dynamic -Wl,--export-dynamic -Wl,--export-dynamic  ../fe-common/silc/libfe_common_silc.a ../fe-common/core/libfe_common_core.a ../silc/libsilc.a ../silc/core/libsilc_core.a ../core/libcore.a ../lib-config/libirssi_config.a ../lib-popt/libpopt.a /tmp/silc-client-1.1-beta5/lib/.libs/libsilcclient.a ../perl/.libs/libperl_core_static.a ../perl/.libs/libfe_perl_static.a -L/usr/local/lib /usr/lib/perl5/5.8.8/i686-linux-thread-multi/auto/DynaLoader/DynaLoader.a -L/usr/lib/perl5/5.8.8/i686-linux-thread-multi/CORE -lperl -lnsl -lm -lcrypt -lutil /usr/lib/libgmodule-2.0.so /usr/lib/libglib-2.0.so /usr/lib/libncurses.so -L/tmp/silc-client-1.1-beta5/lib /usr/local/lib/libsilc.so -ldl -lpthread

Notice /usr/local/lib/libsilc.so -ldl -lpthread on the end, same order as -lsilc  -ldl -lpthread from Makefile.defines_int


libsilc in Makefile.defines_int. Likely where '-lsilc' is coming from.

Makefile.defines_int:SILC_COMMON_LIBS= -L$(silc_top_srcdir)/lib -lsilc  -ldl -lpthread
Makefile.defines_int.in:SILC_COMMON_LIBS= -L$(silc_top_srcdir)/lib -lsilc @LIBS@

No silc in any *.la file, nor any pkgconfig file.

/usr/X11R7/lib/pkgconfig:

(only X11 files, very long list)

 
-> If this wasn't the case then it in fact should have taken the library from 
-> lib/ because there is explicit -L for the linker when compiling the 
-> lib/ subdirectory.  In this case -Llib/ -lsilc should in fact take it from 
-> lib/ if lib/ was compiled.

The first -L parameter adds /usr/local/lib to the search path from the
command line, which then comes before default search
paths. -L/tmp/silc-client-1.1-beta5/lib is actually the last path
added, which makes it searched after /usr/local/lib (or whatever the
first -L is set to, happens to be /usr/local/lib here).

"ld" is from binutils-2.17.50.0.9, the only thing special about it is
that it supports all targets ld can support.

I definately should have cleaned up the old libsilc.so after it wasn't
needed anymore, so this is my fault, but I wanted to post this as I
figured others probably have been building version after version of
silc following the development and might have themselves come upon a
similar problem.
