Unless I misunderstood the report, this is not a bug, this is a feature. The PHP script MUST use xml2-config --cflags to get the preprocessor flags for libxml2. The code MUST use #include <libxml/xxx.h> . The includes are *on purpose* expected to be stored in /usr/include/libxml2/libxml . There should be NO /usr/include/libxml directory or symlink. The libxml version 1 headers are expected to be stored in /usr/include/gnome-xml . If the PHP configuration doesn't use xml2-config to get the include flags it is broken. If it doesn't include libxml2 files using #include <libxml/xxx.h> it is broken too. Get them to fix it. Daniel Ok, fine, but I'm using SRPMS directly from the RawHide distro off of RedHat's FTP site. When I first started this, I was trying to use everthing as it was, but the PHP SRPM that is there won't rebuild as-is with libxml2 installed where it was, and I installed the libxml2-2.4.5 SRPM from RedHat's FTP site as well. As you closed both the GNOME and RedHat's bug reports, please provide me with some advice on how RedHat got this to compile properly using the libxml2-2.4.5 RPM. As RedHat has RPMS available on their FTP site for PHP, RedHat obviously managed to get it to compile against the libxml2 libraries...I just don't know how it worked. Am I missing something else? It wasn't until I modified the libxml2 install paths that it would work. I'm trying to stick as close to the original RedHat configuration as possible, but I'm either missing some dependency that isn't clearly indicated, or possibly the SRPM of PHP I have has a typo/bug in the spec file. Any assistance would be greatly appreciated. Okay, this then becomes a PHP bug. The PHP package should be updated to use xml2-config to grab its libxml2 CFLAGS and LIBS. I tried to look at php-4.0.6/configure.in but was unable to find out where XML compile and link informations were set. Daniel While I was awaiting your reply, I opened a bug against the PHP SRPM. It is 54351. I don't know how you want to handle this current bug report. I'm guessing you'll close it or link it to the other, but I'll let you decide on the best course. I'm curious as to how the pre-made RPMs for PHP, that are available in the RawHide download directories, were created. Was a work-around done to make the compile work? In PHP4.1.0RC1 this problem is correct This should be fixed in php 4.1.2-5. For the record you want ext/*/config.m4 -- configure is built from configure.in + the config.m4s |
I already submitted this to the Gnome project, but was curious how you worked around this problem, as your RawHide SRPMS as they are don't work in this circumstance. When trying to compile the latest version 4.0.6 of PHP using libxml2- 2.4.5, PHP fails to find the necessary .h files for inclusion because it is looking in /usr/include/libxml instead of /usr/include/libxml2/libxml. This can't be corrected easily on the PHP code side, as there are other dependencies that require leaving the include dir set to /usr/include (or /usr/local/include, depending on your pref). I started to patch the PHP files to look in libxml2/libxml, but discovered that the XML parser that is installed by libxml2-2.4.5 also made the assumption of {includedir}/libxml: **** Inside /usr/include/libxml2/libxml/parser.h **** [snip] #include <libxml/tree.h> #include <libxml/valid.h> #include <libxml/xmlIO.h> #include <libxml/entities.h> [/snip] *** End /usr/include/libxml2/libxml/parser.h **** This broke the compile of PHP after I added the libxml2/libxml entries, because parser.h couldn't find /usr/include/libxml/tree.h, /usr/include/libxml/valid.h, etc. My other alternative was to symlink /usr/include/lib2xml/libxml to /usr/include/libxml, which worked, but I ultimately dismissed due to the sloppy nature of the workaround. I found 5 files that specified the libxml2/libxml directory structure, and created a patch for each them (cutting and pasting...wrapping may become damaged, send me an email and I'll attach them). I created patches for the win32 files as well, though I'm not developing on that OS, so I didn't use them when I did my final compile: **** Start configure patch **** --- libxml2-2.4.5/configure.orig Wed Oct 3 15:17:35 2001 +++ libxml2-2.4.5/configure Wed Oct 3 15:18:09 2001 @@ -7087,7 +7087,7 @@ XML_LIBDIR='-L${libdir}' -XML_INCLUDEDIR='-I${includedir}/libxml2/libxml -I${includedir}/libxml2' +XML_INCLUDEDIR='-I${includedir}/libxml -I${includedir}' XML_CFLAGS="" RDL_LIBS="" **** End configure patch **** **** Start dsp/libxml2.def.src patch **** --- libxml2-2.4.5/win32/dsp/libxml2.def.src.orig Wed Oct 3 15:17:35 2001 +++ libxml2-2.4.5/win32/dsp/libxml2.def.src Wed Oct 3 15:21:52 2001 @@ -1,4 +1,4 @@ -/* win32/libxml2/libxml2.def.src +/* win32/libxml2.def.src Pseudo-source used to create a .DEF file for proper dynamic linkage under MSCC. **** End dsp/libxml2.def.src patch **** **** Start libxml2/libxml2.def.src **** --- libxml2-2.4.5/win32/libxml2/libxml2.def.src.orig Wed Oct 3 15:17:35 2001 +++ libxml2-2.4.5/win32/libxml2/libxml2.def.src Wed Oct 3 15:21:22 2001 @@ -1,4 +1,4 @@ -/* win32/libxml2/libxml2.def.src +/* win32/libxml2.def.src Pseudo-source used to create a .DEF file for proper dynamic linkage under MSCC. **** End libxml2/libxml2.def.src patch **** **** Start include/libxml/Makefile.am patch **** --- libxml2-2.4.5/include/libxml/Makefile.am.orig Wed Oct 3 15:17:35 2001 +++ libxml2-2.4.5/include/libxml/Makefile.am Wed Oct 3 15:20:51 2001 @@ -1,6 +1,6 @@ ## Process this file with automake to produce Makefile.in -xmlincdir = $(includedir)/libxml2/libxml +xmlincdir = $(includedir)/libxml xmlinc_HEADERS = \ SAX.h \ @@ -32,6 +32,6 @@ catalog.h install-exec-hook: - $(mkinstalldirs) $(DESTDIR)$(xmlincdir)/libxml2 $(DESTDIR) $(xmlincdir)/libxml2/libxml + $(mkinstalldirs) $(DESTDIR)$(xmlincdir) $(DESTDIR) $(xmlincdir)/libxml EXTRA_DIST = xmlversion.h.in xmlwin32version.h.in **** End include/libxml/Makefile.am patch **** **** Start include/libxml/Makefile.in patch **** --- libxml2-2.4.5/include/libxml/Makefile.in.orig Wed Oct 3 15:17:35 2001 +++ libxml2-2.4.5/include/libxml/Makefile.in Wed Oct 3 15:19:53 2001 @@ -120,7 +120,7 @@ Z_CFLAGS = @Z_CFLAGS@ Z_LIBS = @Z_LIBS@ -xmlincdir = $(includedir)/libxml2/libxml +xmlincdir = $(includedir)/libxml xmlinc_HEADERS = SAX.h entities.h encoding.h parser.h parserInternals.h xmlerror.h HTMLparser.h HTMLtree.h debugXML.h tree.h list.h hash.h xpath.h xpathInternals.h xpointer.h xinclude.h xmlIO.h xmlmemory.h nanohttp.h nanoftp.h uri.h valid.h xlink.h xmlversion.h xmlwin32version.h DOCBparser.h catalog.h @@ -279,7 +279,7 @@ install-exec-hook: - $(mkinstalldirs) $(DESTDIR)$(xmlincdir)/libxml2 $(DESTDIR) $(xmlincdir)/libxml2/libxml + $(mkinstalldirs) $(DESTDIR)$(xmlincdir)/libxml2 $(DESTDIR) $(xmlincdir)/libxml # Tell versions [3.59,3.63) of GNU make to not export all variables. # Otherwise a system limit (for SysV at least) may be exceeded. **** End include/libxml/Makefile.in patch ****
