It was not binaries. Finally got time. Built against previously installed Xulrunner-13.0.1.
Needed to have run-icecat.sh in /usr/lib/xulrunner (this is a linkk to /usr/lib/xulrunner-13.0.1): ./configure make chmod -v 0775 build/unix/run-icecat.sh cp -v dist/icecat/run-icecat.sh /usr/lib/xulrunner/run-icecat.sh make install rm -v /usr/lib/xulrunner/run-icecat.sh rm -rfv /usr/bin/icecat rm -rfv /usr/lib/icecat ln -sv icecat-13.0.1 /usr/lib/icecat ln -sv ../lib/icecat/icecat /usr/bin/icecat Generated icecat-13.0.1 directory binary is about 6.2 MB, mored than 20 MB for a full build, and takes less than 5 min, compared to about 30 in, for a full build. In .mozconfig, added the two lines: # Point to the xulrunner libraries - comment these for a standalone browser ac_add_options --with-system-libxul ac_add_options --with-libxul-sdk=/usr/lib/xulrunner-devel-13.0.1 Xulrunner had been previously built in order to build icedtea-web plugin. You requested me to send a message, when done. -- []s, Fernando -- http://gnuzilla.gnu.org
