Hello all, I compiled and installed DBG and it seemed to go fine: the dbg.so module is in the right place. I did change the --prefix to point to my MAMP PHP5 installation also.

I then followed the INSTALL instructions. I am using ZendOptimizer so I added zend_extension="/path/to/dbg.so" (i entered the actual path). I also added the lines to enable the debugger to my php.ini file. However, when I restarted MAMP (Apache 2.0.55 and MySQL) nothing about DBG showed up in phpinfo()'s output. I'm at a loss.

Any help would be greatly appreciated.

I am running PHP 5.1.2, DBG 2.13.1, and Apache 2.0.55.

Thanks,

Bryan

I tried to update a PEAR package and saw the following:

Failed loading /Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20050922/dbg.so: (null)

I saw a post by someone else having a similar on another board - but they had to create a custom make file (which I don't know how to do ). I have seen things mentioning tar balls of DBG for MAC OS X. I am running 10.4.6 and am wondering if there are any packages, disk images, or tar balls I may use.

I did notice that for the other modules I have (eaccelorator, pdo_mysql, yaz) there is both a .so and .a file. However, for dbg there is only a .so file. Could this be the problem? Is there something in my config that I missed?

Any help would be great,

Thanks,

Bryan

I don't mean to be a pest, but I'm learning more as I research this. I ran otool -L /path/to/dbg.so and got this:

/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20050922/dbg.so:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.5)

I don't know what it means, but I hope it helps.

Thanks,

Bryan

Just don't use ZendOptimizer on the site where you want to debug scripts. It's useless there anyway. Also check if there are any other zend_extensions like opcode caches. They should be turned off too.

If anything looks out of place, please let me know.

Did you compile PHP yourself?
If not, I'd highly recommend you to do it. There are many PHP binary distros for MACOSX which come with symbol tables stripped off leaving you on your own with dynamic extensions. They simply won't load.

So what would the compile process look like? From phpinfo() this is what's in the 'Config Command' section:

'./configure' '--with-mysql=/Applications/MAMP/bin/mysql4' '--with-apxs2=/Applications/MAMP/Library/bin/apxs' '--with-gd' '--with-jpeg-dir=/Applications/MAMP/Library' '--with-png-dir=/Applications/MAMP/Library' '--with-zlib' '--with-freetype-dir=/Applications/MAMP/Library' '--prefix=/Applications/MAMP/bin/php5' '--exec-prefix=/Applications/MAMP/bin/php5' '--sysconfdir=/Applications/MAMP/conf/php5' '--with-soap' '--with-config-file-path=/Applications/MAMP/conf/php5' '--enable-track-vars' '--enable-bcmath' '--enable-ftp' '--enable-gd-native-ttf' '--with-bz2=/usr' '--with-ldap' '--with-mysqli=/Applications/MAMP/bin/mysql4/bin/mysql_config' '--with-sqlite' '--with-ttf' '--with-t1lib=/Applications/MAMP/Library' '--enable-mbstring=all' '--with-curl=/Applications/MAMP/Library' '--enable-dbx' '--enable-sockets' '--enable-bcmath' '--with-imap=shared,/Applications/MAMP/Library' '--enable-soap' '--with-kerberos' '--enable-calendar' '--with-pgsql=shared,/Applications/MAMP/Library/pg' '--enable-dbase' '--enable-exif' '--with-libxml-dir=/Applications/MAMP/Library' '--with-xsl=/Applications/MAMP/Library' '--with-pdo-mysql=shared,/Applications/MAMP/bin/mysql4' '--with-pdo-pgsql=shared,/Applications/MAMP/Library/pg'

Could I just add '--with-debug=/path/to/dbg.so', run ./configure and call make && make install?

Correct and you need all these libraries (devel packages with libraries and headers)


No. Php's configure has no --with-debug option and knows nothing about dbg.
Certainly you can complie without that big number of libraries, just leave only those you need.
