I'm attempting to install Apache 2.0 on AIX 5.2. Ran into problems with my IBM C Compiler, so installed GCC. Configure worked fine. Only used one option in the configure ./configure --enable-so Getting errors on the make command. The command it is running is as follows: Making all in srclib Making all in apr Making all in strings /bin/sh /803Environment/httpd-2.0.50/srclib/apr/libtool --silent --mode= compile gcc -g -O2 -DHAVE_CONFIG_H -U__STR__ -D_THREAD_SAFE -D_USE_IRS -I../ include -I../include/arch/unix -c apr_snprintf.c && touch apr_snprintf.lo The error: In file included from ../include/apr_portable.h:46, from apr_snprintf.c:22: /usr/include/pthread.h:554: error: parse error before '*' token /usr/include/pthread.h:557: error: parse error before '*' token /usr/include/pthread.h:561: error: parse error before '*' token /usr/include/pthread.h:564: error: parse error before '*' token /usr/include/pthread.h:567: error: parse error before '*' token /usr/include/pthread.h:570: error: parse error before '*' token /usr/include/pthread.h:573: error: parse error before '*' token /usr/include/pthread.h:576: error: parse error before '*' token /usr/include/pthread.h:579: error: parse error before '*' token /usr/include/pthread.h:583: error: parse error before '*' token /usr/include/pthread.h:586: error: parse error before '*' token make: 1254-004 The error code from the last command is 1. I installed gcc binaries without any configuration. Any ideas greatly appreciated. Tom Richardson Application Services (336) 373-2016 tom.richardson@xxxxxxxxxxxxxxxxx
