Hi,
I'm currently working on a PHP's Grizzly extension via the
com.sun.grizzly.Adapter class, and today I've hit a wall :-). What I
want to do is:
Client --> Request --> Grizzly --> PHPAdapter -- JNI Call --> libphp5.so
Inside the PHPAdapter, I did:
> static {
> System.loadLibrary("php5");
> }
so far so good. Now problems :-) Since I'm working on linux, I need to
build the libphp5.so from scratch. So I've followed the instruction
(many many many times ;-) by building Apache2 from scratch, and then
build php 5 using Apache 2. At the end, I'm getting the libphp5.so,
which is what I need. Then, I start Grizzly HTTP Server with:
% java -Djava.library.path=/usr/local/apache2/lib/ -jar
grizzly-http-1.7-SNAPSHOT.jar 8080 /www/php
And *always* get:
> java.lang.UnsatisfiedLinkError: /usr/local/apache2/modules/libphp5.so: /usr/local/apache2/modules/libphp5.so: undefined symbol: ap_rwrite
> at java.lang.ClassLoader$NativeLibrary.load(Native Method)

> at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1676)
> at java.lang.Runtime.loadLibrary0(Runtime.java:822)
> at java.lang.System.loadLibrary(System.java:993)
Which is expected, because:

[cut ... more than 20]
Now the ap_* stuff is from Apache2, which is probably dynamically loaded
when Apache2 start. Now how can I make sure the libph5.so gets all its
dependencies loaded from java? I did try to add the path to Apache 2
*.so file to my -Djava.library.path but still get the same exceptions. I
did build the libphp5.so on two linux kernel and os X, and always get
the same exception.
I'm probably missing something trivial :-) Any help appreciated :-)
Thanks
