Hi! All, I'm Leo. Hi! I'm install PDFlib rpm files (pdflib-4.0.1-1,pdflib-tcl-4.0.1-1,pdflib-devel-4.0.1-1). My PHP configure lines: ./configure --with-mysql=/usr/local/mysql --with-apache=/usr/src/apache_1.3.19 --enable-ftp --enable-discard-path --with-pdflib=/usr/lib --with-gd That's OK! System don't response any error messages! Then, I compile PHP and Apache source code. No any error messages during compiling. But.. It still can't use any pdf functions like pdf_open(). My Linux box will tall me "Fatal error: Call to undefined function.." I tried to compile PHP with PDFlib again, and saw some information: (1) checking whether to include PDFlib support... yes (2) creating ext/ftp/Makefile creating ext/gd/Makefile creating ext/mysql/Makefile creating ext/pcre/Makefile creating ext/pcre/pcrelib/Makefile creating ext/posix/Makefile creating ext/session/Makefile creating ext/standard/Makefile creating ext/xml/Makefile creating ext/xml/expat/Makefile creating ext/xml/expat/xmlparse/Makefile creating ext/xml/expat/xmltok/Makefile ==> It did not create ext/pdf/Makefile! P.S: Before compile PHP, I have updated the PHP source sode from PHP and Zend CVS. My commands are: ==> # cvs -d :pserver:[EMAIL PROTECTED]:/repository co php4 ==> # cd php4 ==> # cvs -d :pserver:[EMAIL PROTECTED]:/repository co Zend TSRM ==> # cp -r * /usr/src/php-4.0.5/ Is this a bug at php-4.0.5? How can I do that you recommend? P.S: I did checkout the CVS on May 22 morning in Taiwan. Please click the following URL for my questions, thanks: http://www.php.net/bugs.php?id=11014 Big Thanks!
