Guys, There is a strange lines in chan_ss7 Makefile install: install -m 755 -d $(INSTALLPATH) install -m 644 chan_ss7.so $(INSTALLPATH) cd $(INSTALL_PREFIX) && rm -f $(COMPONENT) && ln -s $(COMPONENT)-$(VERSION) $(COMPONENT) cd $(INSTALL_PREFIX)/asterisk/usr/lib/asterisk/modules && ln -sf ../../../../../$(COMPONENT)/usr/lib/asterisk/modules/* . The last line is wrong and make install results an error since there is no such directories like /asterisk. secondly it does not install a chan_ss7.so file into /usr/lib/asterisk/modules for me - I've just copied it manually. Also can anyone explain for me why "install:" made in such way in 0.8.4 since we just need to copy chan_ss7.so into modules dir and nothing more? so the line like was in 0.8.3 works perfect install: install -m 644 chan_ss7.so $(INSTALL_PREFIX)/usr/lib/asterisk/modules/ Regards, Anton. PS: I'm installing that on Debian stable.
