I checked out PHP4 / Zend from CVS and tried it out there. My system has libtool 1.3.5 and make 3.77. It may be me, though ... to do the PHP_REQUIRE_CXX thing, I placed a line which just said PHP_REQUIRE_CXX inside my conditional "if sword is enabled." Other than that, Makefile.in is modified: ---------- # $Id$ LTLIBRARY_NAME = libsword.la LTLIBRARY_SOURCES = sword.c LTLIBRARY_SHARED_NAME = sword.la LTLIBRARY_OBJECTS_X = sword_int.lo include $(top_srcdir)/build/dynlib.mk ---------- and the files in the directory include sword_int.cxx, sword.c, and sword_int.h. I got a warning a couple of times from buildconf: configure.in:609: AC_PROG_CXXCPP was called before AC_PROG_CXX The output from make in this directory now: [john@wyoming sword]$ make make[1]: Entering directory `/home/john/cvs/php4/ext/sword' gcc -DHAVE_CONFIG_H -I. -I/home/john/cvs/php4/ext/sword -I/home/john/cvs/ph p4 -I/home/john/ cvs/php4/main -I/home/john/cvs/php4/Zend -I/home/john/cvs/php4 -I/home/john/ cvs/php4/ext/mys ql/libmysql -I/home/john/cvs/php4/ext/xml/expat/xmltok -I/home/john/cvs/php4 /ext/xml/expat/x mlparse -DXML_BYTE_ORDER=12 -g -O2 -c sword.c && touch sword.lo /bin/sh /home/john/cvs/php4/libtool --silent --mode=link cc -DHAVE_CONFIG_H -I. -I/home/jo hn/cvs/php4/ext/sword -I/home/john/cvs/php4 -I/home/john/cvs/php4/main -I/ho me/john/cvs/php4 /Zend -I/home/john/cvs/php4 -I/home/john/cvs/php4/ext/mysql/libmysql -I/home /john/cvs/php4/e xt/xml/expat/xmltok -I/home/john/cvs/php4/ext/xml/expat/xmlparse -DXML_BYTE _ORDER=12 -g -O2 -o libsword.la sword.lo sword_int.lo ar: sword_int.o: No such file or directory make[1]: *** [libsword.la] Error 1 make[1]: Leaving directory `/home/john/cvs/php4/ext/sword' make: *** [all-recursive] Error 1 [john@wyoming sword]$ make make[1]: Entering directory `/home/john/cvs/php4/ext/sword' /bin/sh /home/john/cvs/php4/libtool --silent --mode=link cc -DHAVE_CONFIG_H -I. -I/home/jo hn/cvs/php4/ext/sword -I/home/john/cvs/php4 -I/home/john/cvs/php4/main -I/ho me/john/cvs/php4 /Zend -I/home/john/cvs/php4 -I/home/john/cvs/php4/ext/mysql/libmysql -I/home /john/cvs/php4/e xt/xml/expat/xmltok -I/home/john/cvs/php4/ext/xml/expat/xmlparse -DXML_BYTE _ORDER=12 -g -O2 -o libsword.la sword.lo sword_int.lo ln: sword_int.o: File exists make[1]: *** [libsword.la] Error 1 make[1]: Leaving directory `/home/john/cvs/php4/ext/sword' make: *** [all-recursive] Error 1 Note the second time I run make it says "sword_int.o: File exists." Not sure why this is. I'd also like to note that since other people seem to prefer CC or perhaps something else, I have no trouble changing to adapt :) --John P.S. It looks like the Support page has out-of-date CVS instructions: the cvs.zend.net part was not there. Additionally, on the real CVS instructions at cvs.php, it ought to note that you should cd into the php directory before checking out Zend and TSRM.
