Welcome.

hi,

I do not use MSIDE's to write php what are my current options in terms of a client. can i use the shell commands or can i write a vb application as debug console.

Any help will be appriciated!

by the way the sever installed smoothly in my win32 machine!

Currently, I do not use MSIDE as PHP editor too. Only as PHP, JScript and Java debugger.

Concerning VB application, you can write it if you familiar with COM. The only thing you should develop is COM object that implements COM category CATID {5FB17280-9D56-11D4-BB79-C5E0247B842E} and interface IPhpDbgSite. I can send you an IDL file with necessary interface definitions.

I am using:

php-4.0.4pl1 compiled into apache_1.3.14rusPL30.0

which runs under FreeBSD4-stable platform.

The client is PHPEd 2.3.1 beta. (www.soysal.com)

I followed all the instructions on http://dd.cron.ru/dbg/, put the dbg server sources into phpsrc/ext dir, and produced the httpd binary with my favorite shell script:

#!/usr/local/bin/bash

#phpdir="/home/yar/php-4.0.3pl1"
phpdir="/home/yar/php-4.0.4pl1"
apachedir="/home/yar/apache_1.3.14rusPL30.0"
uwimapdir="/home/yar/imap-2000.RELEASE-CANDIDATE.7"

cd $apachedir
make clean
./configure || exit
cd $phpdir
make clean
make distclean
rm config.cache
#./configure --with-mysql --with-apache=$apachedir --enable-track-vars --with-mod-charset --with-imap=$uwimapdir --with-gettext --enable-force-cgi-redirect --with-gd=/usr/local --with-xml || exit
./configure --with-mysql --with-apache=$apachedir --enable-track-vars --with-mod-charset --with-imap=$uwimapdir --with-gettext --enable-force-cgi-redirect --with-gd=/usr/local --with-xml --enable-trans-sid --enable-dbg=shared || exit
make && make install || exit
cd $apachedir
./configure --prefix=/home/httpd --activate-module=src/modules/php4/libphp4.a || exit

make || exit

The suspicious thing is that dbg.so wasn't created after that.

Though I added the following into server's php.ini:

extension=dbg.so

[debugger]
debugger.enabled = true
debugger.host = <ip of the PHPEd host>

debugger.port = 7869

Then I tried to get these trace/step buttons enabled in PHPEd by entering httpd's ip or localhost (where win32 debug listener runs), copying php.ini to windows pc and giving it to PHPEd, istalling registry items from the client distr. package, but nothing helped...

What have I done wrong?

Also the three-part scheme looks not evident for me. Why do you need the separate debug listener?

I followed all the instructions

I see no ./buildconf at your script

Now the build sequence looks like:

#!/usr/local/bin/bash

phpdir="/home/yar/php-4.0.4pl1"
apachedir="/home/yar/apache_1.3.14rusPL30.0"
uwimapdir="/home/yar/imap-2000.RELEASE-CANDIDATE.7"

cd $apachedir
make clean
./configure || exit
cd $phpdir
make clean
make distclean
rm config.cache
./buildconf
./configure --with-apxs=/home/httpd/bin/apxs --enable-track-vars --with-mod-charset --with-imap=$uwimapdir --with-gettext --enable-force-cgi-redirect --with-gd=/usr/local --with-xml --enable-trans-sid --enable-dbg=shared || exit
(make && make install) || exit
cd $apachedir
./configure --enable-module=so --prefix=/home/httpd || exit

make || exit

You see, I moved to the DSO model like you.

Also I noticed that the Makefile of your dbg.tar.gz contains specific absolute paths:

File: Makefile Col 0 465 bytes 100%
top_srcdir = /usr/local/src/php4-200012130245
top_builddir = /usr/local/src/php4-200012130245
srcdir = /usr/local/src/php4-200012130245/ext/dbg
builddir = /usr/local/src/php4-200012130245/ext/dbg
VPATH = /usr/local/src/php4-200012130245/ext/dbg

$Id$

LTLIBRARY_NAME = libdbg.la
LTLIBRARY_SOURCES = dbg.c dbg_core.c
LTLIBRARY_SHARED_NAME = dbg.la
LTLIBRARY_SHARED_LIBADD = $(DBG_SHARED_LIBADD)

include $(top_srcdir)/build/dynlib.mk

I edited it to:

topdir = /home/yar/php-4.0.4pl1
top_srcdir = $(topdir)
top_builddir = $(topdir)
srcdir = $(topdir)/ext/dbg
builddir = $(topdir)/ext/dbg
VPATH = $(topdir)/ext/dbg

$Id$

LTLIBRARY_NAME = libdbg.la
LTLIBRARY_SOURCES = dbg.c dbg_core.c
LTLIBRARY_SHARED_NAME = dbg.la
LTLIBRARY_SHARED_LIBADD = $(DBG_SHARED_LIBADD)

include $(top_srcdir)/build/dynlib.mk

The apache compiles and works, but the debugging features are still disabled.

Where should that dbg.so be created and do I control this step. No errors are reported, but "find / -name dbg.so" gives nothing.

Delete configure script.
run ./buildconf
make sure ./configure created and
Makefile at the ext/dbg/ directory has been renewed. (all your editions made to this file should be lost).
make sure ./configure contains references to DBG

ususally result dbg.so might be found in the modules directory (where the others are).

Manually copy them into apache/libbin dir and make sure http.conf contains LoadModule with proper absolute path to php4lib.so (which is also at the libbin).

Ok, thanks. Still some steps have to be done.

Yes, deleting "configure" before running "buildconf" changed things. Now I really got modules/dbg.so which I copied to httpd/libexec/ and placed it near the newly-generated libphp4.so.

The libphp4.so is loaded by:

LoadModule php4_module libexec/libphp4.so

string of httpd.conf. The dbg.so should be loading by:

extension_dir = ./

extension=dbg.so

strings of php.ini.

But searching the <? phpinfo(); ?> result for "dbg" substring gives only one match: "--enable-dbg=shared" in the stored "configure" command. Is it correct? How do I check if the extension is loaded?

Possibly, the dbg.so is already working but I misconfigured the client's PHPEd or Debug Listener. The PHPEd setup isn't very evident at this. There are two groups of controls in Properties/PHP tab: one for PHP 3.x and the other for php 4. The debug listener is invoked after editing the php 3.x group!

Hi I wanted to download the debugger the server is "down".
Where can I find a mirror to download the debugger?

Anon

Though, I didn't manage to use the debugger on my system anyway.

Anon

Red Hat Linux, php4.0.4pl1, Apache 1.3.12
I deleted the configure file, ran ./buildconf, ran ./configure with --enable-dbg=shared but when the configure-skript comes to the part where it configures dbg I always get the message ":command not found" three times and the configuration stops.
What the heck is wrong?
