Description:
------------
Trying to install memcache pecl module in a Ubuntu Edgy Eft box i get the error on ./configure

checking for session includes... configur: error: Cannot find php_session.h

Checking at the configure script, on line 4109:

  if test "$PHP_MEMCACHE_SESSION" != "no"; then
        { echo "$as_me:$LINENO: checking for session includes" >&5
echo $ECHO_N "checking for session includes... $ECHO_C" >&6; }
    if test -f $abs_srcdir/include/php/ext/session/php_session.h; then
      session_inc_path=$abs_srcdir/include/php
    elif test -f $abs_srcdir/ext/session/php_session.h; then
      session_inc_path=$abs_srcdir
    elif test -f $prefix/include/php/ext/session/php_session.h; then
      session_inc_path=$prefix/include/php
    else
      session_inc_path=""
    fi


But in Ubuntu the package php4-dev install it includes on /usr/include/php4/ext/session
all tests check in include/php, to build this module i have to create a sym link /usr/include/php to /usr/include/php4

Thanks.



Reproduce code:
---------------
./configure when php4 devel files aren?t in /usr/include/php

Expected result:
----------------
./configure finish without error.

Actual result:
--------------
checking for the location of ZLIB... no
checking for the location of zlib... /usr
checking for session includes... configure: error: Cannot find php_session.h

That's not something we can fix.
If they use patched PHP, you have to patch PECL/memcache accordingly.

Hmm, ok!

I was thinking in something like:

10a11,13
> PHP_ARG_WITH(dev-headers, specify path of php headers files,
> [  --with-dev-headers[=PATH]       specify path of php headers files], no, no)
>
73a77,78
>     elif test -f $PHP_DEV_HEADERS/ext/session/php_session.h; then
>       session_inc_path=$PHP_DEV_HEADERS


Then a user can specify in case like debian/ubuntu or when he compile and dont install on default places!

Thanks for attention.

Have the same Problem with a Debian Sarge (3.1)

My workaround:
 ln -s /usr/include/php4 /usr/include/php

Fixed things for me.

"That's not something we can fix.

What kind of BS reply is that?!

The configure script for memcache looks in some predefined locations which are based on assumption instead of using the *properly detected* location of the include files earlier in the configure script through php-config.

See here:

checking for PHP includes... -I/usr/lib/php4/include/php -I/usr/lib/php4/include/php/main -I/usr/lib/php4/include/php/TSRM -I/usr/lib/php4/include/php/Zend
[...]
checking for session includes... configure: error: Cannot find php_session.h

If the configure script would just check the locations returned by the PHP includes check, all would be fine.

After some more digging i found out that the current config9.m4 already sort-of looks in the include dirs returned by php-config, only the problem is, the current approach only works for php5.

Memcache's config9.m4 uses the $phpincludedir m4 var which, afaik, is not available in php4 phpize (compare phpize.m4 between php5 and php4 and see what i mean)

One bit hackish way to fix it would be to add a check for:

${prefix}/include/php/ext/session/php_session.h
