Install problems (unix.h)

I have been having problems installing php 4.2.1 on Solaris 2.6, and have been running into that unix.h problem. I have used what was listed in the archives as a solution and it didn't work. Here's what I'm doing: ./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-apache=../apache_1.3.26 This of course, picks up the unix.h. Following the archive solution, I commented out the include line in the zend.h file and the main/php.h file. When I run make after this, I now get this: Making all in Zend /bin/sh ../libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../main -D_POSIX_PTHREAD_SEMANTICS -I../TSRM -g -O2 -prefer-non-pic -static -c -o zend_language_parser.lo `test -f zend_language_parser.c || echo './'`zend_language_parser.c In file included from ../main/php_config.h:2084, from zend_config.h:1, from zend.h:48, from zend_compile.h:24, from zend_language_parser.c:147: /usr/include/stdlib.h:53: warning: empty declaration In file included from ../main/php_config.h:2088, from zend_config.h:1, from zend.h:48, from zend_compile.h:24, from zend_language_parser.c:147: /usr/include/sys/types.h:253: warning: empty declaration /usr/include/sys/types.h:354: warning: empty declaration /usr/include/sys/types.h:355: warning: empty declaration And this continues for almost every program, then it finally fails at the end with some other file not being found. What's going on here? I had JUST compiled this version on another 2.6 machine last week, and was able to get around the unix.h by changing the config.cache line to "no" and re-running configure. Now, I can't get anything to work. Any suggestions? Is this really related to that unix.h file? Where IS this unix.h? (I did a find on /usr, /bin, /lib and I can't find it anywhere.) ---------- Gardiner D. Leverett gdl@merit.edu Merit Network, Inc.
