Hiya,
We're using PHP/Java Bridge (PJB) with PHP 5.1.6 and Apache 2.0.61 on
Windows, and experiencing frequent segfaults of Apache. Inspecting the
dump reveals that PHP is crashing somewhere, something to do with a null
pointer exception when reporting an error - seemingly not in the
php/java module but elsewhere (although I'm no expert).
I've tried using the same combination but with the latest Apache
(2.2.6), but the segfault still happens.
It seems to happen most (and reproducibly) when getting requests through
a flex client, when an open connection already exists from a flex client
on the same machine (i.e. one browser window runs the flex client, and
opens a popup window also with the flex client running).
Firstly, has anyone experienced this?
So, I'm trying to update to the latest version of PHP (5.2.5), but
coming up against some problems when attempting to build PHP, which I'm
doing in order to build a PJB module to work with it. I've tried to
build PHP using Cygwin, cross-compiling against mingw32, but that failed
with a number of build errors, presumably related to incompatible libs
and includes.
Instead I tried using MS's Visual Studio C++, as in the documentation in
the PHP build directory. Firstly I couldn't get the configure script to
find the win32build folder, so I added it to PATH and tried again.
Then, the configure script ran successfully, but nmake fails with:
"" -h win32\ -r Release_TS\ -x Release_TS\ win32\build\wsyslog.mc
'-h' is not recognized as an internal or external command, operable
program or batch file.
NMAKE : fatal error U1077: '"' : return code '0x1'
Stop.
It would appear that PHP's configure script isn't writing the make rules
properly, and is setting an empty string instead of the name of some
build tool.
Can anyone help with this? Is there a way of building the PJB module
for this version of PHP in win32 that doesn't require a build of PHP
itself?
We must have it sorted by next Wednesday (the 19th), and we're willing
to pay a reasonable rate for assistance.
Cheers,
Mike
First of all, PHP must be built with MSVC, mingw is not really
supported, and cygwin is only supported to run on the cygwin layer
(building with mingw is not supported via cygwin)
Secondly, PHP builds fine with all versions of MSVC (even the latest
2008 edition) but setting up the compile environment can be slightly
complicated. In addition to the php source code and a version of MSVC,
you also need the Windows Platform SDK (included with the full versions
of MSVC, but must be installed separately for the express versions).
If you're using VC6 you also must apply the latest service pack and
upgrade to the last Windows Platform SDK that supports VC6 (Februrary
2003) and add them to your VC command line environment batch file - in
addition you'll need to use the newer nmake.exe from the platform sdk
(but not the other compile tools from the SDK - it's easiest to simply
rename the old nmake.exe and copy the new one to the same location).
Then you need all the libraries that PHP currently requires. They can
be found at http://files.edin.dk/php/win32/zip.zip - yes I know,
original name. Caution, this is a large download because it contains
not only the standard libraries needed but also any libraries used for
PECL extensions. The zip archive pointed to in the manual is supposed
to have just the core libraries required but is sadly out of date.
Unzip the resulting files and place them parallel to your php source
code - it'll look for the php_build and template directories - you can
put them elsewhere but then you have to mess with configure flags, it's
easier just to put them in the automatically detected location.
Once you have a compile environment set up, the source code available,
and the required zip.zip files you can open up a visual studio command
prompt and cd into your php source code, and run your configure.
Currently there is no way to do the equivalent of "phpize" on nix on a
windows system to build just one extension against an existing php and
libs. This is something I have on my "list of things to do" but time
and energy is scarce. You can set up a makefile by hand if you really
know what you're doing. Just make sure to link against the right PHP
lib and provide the preprocessor defines needed.
I also provide PHP builds in several compilers in several formats at
perisama.net if you're looking for debug versions of PHP - if you have
more questions feel free to ask.
Thanks,
Elizabeth Smith
