Linux

Hi !

I'm tring to compile php-5.0.3 on Linux RH AS 2.1 with Informix functions support. And I've recieved following messages:

# ./configure --with-informix --with-apache=/usr/src/Apache/apache_1.3.23

I tried to run cofigure without options, but result was the same.
Could you tell me, if there is problems with compiller

As the log tells you, it cannot find the "lex" command. Try

which lex

to see whether one exists. If not, try to install it and see if configure goes OK. I have compiled PHP5 on a number of Linux installations involving different distros, and all of them have been very smooth.

I installed flex and pass this error message.

Thank you!
