## #46779 — Jess Portnoy — 2010-01-18T10:12:34+00:00

URL: https://externals.io/message/46779#46779

Hello all,

When attempting to build only the libZend.a by executing:
#cd /Zend
Zend# ./buildconf
One gets this message [redundant output was truncated]:
Makefile.am: Lex source seen but `LEX' is undefined
Makefile.am:   The usual way to define `LEX' is to add `AM_PROG_LEX'
Makefile.am:   to `configure.in' and run `aclocal' and `autoconf' again.
buildconf: keeping configure

Adding AM_PROG_LEX solves this problem.
Compiling only the archive can be useful for various things so I think 
this should be made operational, especially since I don't see any down 
side to it.

Attaching a patch.

Thanks,
