[PHP-DEV] RE: Bug #10738 Updated: socket functions cause php4 to segmentation fault
Jani--
I can't compile the latest snapshot for some reason, weird errors come out:
Making all in Zend
lex -Pzend -ozend_language_scanner.c -i ./zend_language_scanner.l
lex: illegal option -- P
Usage: lex [-ewctvnVY] [-Q(y/n)] [file]
*** Error code 1
make: Fatal error: Command failed for target `zend_language_scanner.c'
Current working directory /root/src/php/php4-200105100645/Zend
*** Error code 1
make: Fatal error: Command failed for target `all-recursive'
If there is anything different between the latest snap shot and the way the
live one on the website is, please let me know so I can make the
changes..I'm just trying to do a basic install. Thanks..

Ok, I think the problem was I was strip'ing the binary before moving it
around. Try this:

I think the '--enable-debug' didn't get accounted for.
Please try deleting config.cache and reconfigure/compile PHP again.
Then generate that gdb bactrace. Hopefully it will have more info in it.
