I had this problem when trying to install Cairo extension for php with PECL. this workaround does worked for me i.e. cat all the old files, but you have to include the NEW libtools.m4 file to !
First copy all the files incase of error ! ** my files are located in /usr/share/aclocal. I'm on ubuntu 8.10 ** cd /usr/share/aclocal mkdir ~/libtoolsbackup cp lt~obsolete.m4 ltoptions.m4 ltsugar.m4 ltversion.m4 libtool.m4 ~/libtoolsbackup cd ~/libtoolsbackup cp libtool.m4 libtool.m4.backup rm libtool.m4 cat lt~obsolete.m4 ltoptions.m4 ltsugar.m4 ltversion.m4 libtool.m4.bakup >> libtool.m4 before this next step, make sure you have the above files backed-up ! sudo cp libtool.m4 /usr/share/aclocal/ -- phpize: configure:8184: error: possibly undefined macro: _LT_SET_OPTIONS https://bugs.launchpad.net/bugs/262251 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
