Installation problems - swscale.h: No such file or directory

[Andreas Waltl]

I installed ffmpeg with --enable-shared option successfully. But
there occurs an error while compiling ffmpeg-PHP:

/usr/include/php5/ext/ffmpeg-php-0.6.0/ffmpeg-php.c:46:21: error:
swscale.h: No such file or directory
/usr/include/php5/ext/ffmpeg-php-0.6.0/ffmpeg-php.c: In function
âzm_info_ffmpegâ:
/usr/include/php5/ext/ffmpeg-php-0.6.0/ffmpeg-php.c:156: error:
âLIBSWSCALE_IDENTâ undeclared (first use in this function)
/usr/include/php5/ext/ffmpeg-php-0.6.0/ffmpeg-php.c:156: error: (Each
undeclared identifier is reported only once
/usr/include/php5/ext/ffmpeg-php-0.6.0/ffmpeg-php.c:156: error: for
each function it appears in.)
make: *** [ffmpeg-php.lo] Error 1

Does anybody know what to do now?

Can you explain the process of you installed with enabled shared -
take it that was configure command?

Thanks

[Andreas Waltl]

I followed exactly the steps in the INSTALL file - it was ./configure
&& make

REQUIREMENTS
============

ffmpeg-0.4.9pre1 or higher built with the --enable-shared option and
without the --enable-swscale option (ffmpeg svn recommended)
php-5.0.x or higher. For php-4.x.x, use ffmpeg-php-0.5.1 or older.
gd-2.0.x or higher or the version of GD bundled with PHP

INSTALLATION INSTRUCTIONS
=========================

These instructions are for Linux since I don't have windows. If you
successfully build on windows, let me know how you did it and I'll
update
these instructions.

BUILDING FFMPEG
---------------

cd /path/to/ffmpeg
./configure --enable-shared --prefix=/usr
make clean && make
[become root]
make install


BUILDING FFMPEG-PHP AS A SHARED EXTENSION
-----------------------------------------

1. Build php if not already built or installed by your distro (See the
file INSTALL in your php source directory)

2. Unpack the archive

tar -xjf ffmpeg-php.X.x.x.tbz2 -C /path/to/php_sources/ext/

3. cd into the ffmpeg extension directory

cd /path/to/php_sources/ext/ffmpeg-php.X.X.X/

4. Run phpize (included with your php install) to build configuration
files

phpize

5. Configure and build

./configure && make

6. Install the shared extension

make install (as root)

Did you build ffmpeg from source or is it from an rpm (or other pkg)

Try rebuilding ffmpeg with --enable-swscale

Run ldd on your ffmpeg binary to see if it's really building in swscaler

ldd /usr/bin/ffmpeg | grep swscale

Returns: libswscale.so.0 => not found

[Andreas Waltl]

I configured ffmpeg with following command:
./configure --enable-shared --enable-swscale --enable-gpl --prefix=/
usr

[Todd Kirby]

Seems like the libswscale.so.0 and swscale.h file aren't getting installed for some reason. When you run ffmpeg from the commandline does it complain about missing libswscale.so.0?
