[gentoo-user] problem with php and sablotron solved.

[Vesselin Mladenov]

Hi,
A couple of hours ago I posted here about a problem with php and
sablotron. I have solved the problem, but I am posting here my (may be
a bit dirty) solution - someone may save a couple of long hours.
The problem was that php-4.4.2,  for no obvious reason, does not
detect that sablotron is properly compied with encoding. The result is
that xslt_set_enconding() wrapper function is not compiled in  php.
This detections is made at configure time: php checks if two code
sniplets containing SablotSetEncoding and SablotGetOptions can be
compiled and linked against libsablot.  If php finds one of the
functions it defines in php_config.h HAVE_SABLOT_SET_CONFIG and
HAVE_SABLOT_GET_OPTIONS macros respectively.

I have verified carefully that sablotron has his SablotSetEncoding and
SablotGetOptions compiled in, existing as symbols in libsablot.so and
usable. So the next time I tried to emerged php I started it with:

CPPFLAGS="-DHAVE_SABLOT_SET_ENCODING=1 -DHAVE_SABLOT_GET_OPTIONS=1"  \
emerge php

The configure script did not detect the functions properly again, but
the compiler was forsed to compile xslt_set_encoding() and
xslt_get_options() php functions.

I confess that this solution is far from being clean, but still it
works and may do a good job as a workarround, especially when your
vacation has already started.
