RC5 Compile problem

Hi, Just playing around, I have 3.0.12 working nicely by itself. I recompiled 3.0.12 with versioning enabled. No problems there. I downloaded the rc5 src, untarred it and configured thus: ./configure --with-apxs=/usr/sbin/apxs --with-mysql --with-zlib --enable-versioning (Same config line used with php-3.0.12) No problems. Then running 'make', I got... [root@linuxbox php-4_0b3_RC5]# make make all-recursive make[1]: Entering directory `/usr/src/php-4_0b3_RC5' Making all in libzend make[2]: Entering directory `/usr/src/php-4_0b3_RC5/libzend' /bin/sh ./libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I/usr/src/php-4_0b3_RC5/./libzend -I. -g -O2 -g -c zend_execute.c zend_execute.c: In function `execute': zend_execute.c:2118: virtual memory exhausted make[2]: *** [zend_execute.lo] Error 1 make[2]: Leaving directory `/usr/src/php-4_0b3_RC5/libzend' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/php-4_0b3_RC5' make: *** [all-recursive-am] Error 2 ================================= Attempts to add additional swapfile space yielded a longer wait time until the same message appeared.
