Wireshark-bugs: [Wireshark-bugs] [Bug 10790] link against freshly compiled libraries first
Comment # 5
on bug 10790
from Jeroen Roovers
What the patch does is make sure you link against libraries in the build tree
first and only then against libraries found elsewhere like in @*_LIBS@, which
may or may not include (possibly incorrect) directives such as -L$libdir which
could cause wireshark to link against stale libraries from an older wireshark
install. The reordering makes sure you list freshly built libraries first and
only then @*_LIBS@ (including -L$/usr/lib/somelibdir) and more generic link
time dependencies (such as -lm).
An order like this:
@GEOIP_LIBS@ \
${top_builddir}/wiretap/libwiretap.la @GLIB_LIBS@ \
${top_builddir}/wsutil/libwsutil.la
might cause libtool to pick the wrong libwsutil based on what @GLIB_LIBS@ (or
in remote cases even libwiretap.la) happens to contain.
In fact libtool itself generates the same type of ordering I suggested here:
./wiretap/.libs/libwiretap.la:
dependency_libs=' .../wireshark/wsutil/libwsutil.la -lgcrypt -lgpg-error
-lgthread-2.0 -lgmodule-2.0 -lglib-2.0 -lz -lm -lnl-route-3 -lnl-genl-3 -lnl-3
-lsbc'
Objects first, then archives.
