Hi,

I'm trying to build php 5.2.1 on windows and am hitting the following
problem at link time ....

Creating library Release\php5ts.lib and object Release\php5ts.exp
libxml.obj : error LNK2019: unresolved external symbol _xmlDllMain
referenced in function _DllMain@12
Release\php5ts.dll : fatal error LNK1120: 1 unresolved externals
NMAKE : fatal error U1077: '"C:\Program
Files\Intel\CPP\Compiler81\IA32\bin\icl.
exe"' : return code '0x460'

I am linking it to a libxml2.lib that I have compiled. When I do a dumpbin i
do not see the _xmlDllMain symbol. I tried downloading some libxml2 binaries
but they didn't have that symbol either.

Would appreciate some help on this issue.

Thanks,
Rashmi

That symbol is not made available by default in the builds.

You have a couple of options:
1) Use my libxml2 builds - the ones that the official binaries are built
off of. http://ctindustries.net/libxml/
I haven't had a chance to publish the .29 build and was not satisfied
with the .27 and .28 builds to build those, so all I have are .26 until
I have time.

2) Build libxml2 2.6.29 from source (must compile with a MS compiler)
and have PHP link against the libxml2_a_dll.lib file. I added that to
the default libxml2 MSVC build but still need to commit the additon to
the PHP build system (will be post 5.2.4). Once done, then the official
libxml2 binaries (2.6.29+) will be able to be used.
all you need to do is change the config.w32 file in ext/libxml to:

if (CHECK_LIB("libxml2_a_dll.lib;libxml2_a.lib", "libxml") &&
*AND* add the LIBXML_STATIC_FOR_DLL flag
ADD_FLAG("CFLAGS_LIBXML", "/D LIBXML_STATIC /D LIBXML_STATIC_FOR_DLL ");

I tried #2 but it didn't seem to help. I'm working with libxml2 2.6.27 and
so I had to build libxml2_a_dll.lib by referring to the makefiles in 2.6.29.
But now I get some additional warnings, old problem persists :(

Any idea what I might be doing wrong!

It won't work with un-modified 2.6.27 code. I had also made a few
modifications to threads.c and threads.h, which were committed for
2.6.29. Is there any reason you need .27 and can't use the .26 (or build
against .29)?

I was using .27 on linux and had to get the same working on windows as well,
so am using that version.
Will using .29 solve my problem of not being able to build on windows? Is
that a recommended version anyway? Then I could probably upgrade to .29 -
although it would save me some effort in being able to work with .27 itself.

Thanks,
Rashmi

..29 will solve your problem and contains the latest bug fixes so always
recommended. As in my last message, if you want to use .27 on windows,
you need to patch threads.c and threads.h with the changes that are in
..29 to get the symbol properly exposed and exported.

Thanks Rob. I'll go with the patching for now.
