[FFmpeg-user] configure error with enabling libmodplug

[Kimio Miyamura]

Hi, 

I'm trying to build ffmpeg with libmodplug codec.  
When I run "./configure --enable-libmodplug", it always ends with error libmodplug not found.

$ ./configure --enable-libmodplug
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
ERROR: libmodplug not found

I searched web and found that modification of ffmpeg configure script is required: 
https://trac.macports.org/ticket/36942 <https://trac.macports.org/ticket/36942>

-enabled libmodplug        && require libmodplug libmodplug/modplug.h ModPlug_Load -lmodplug
+enabled libmodplug        && require libmodplug libmodplug/modplug.h ModPlug_Load -lmodplug -lstdc++

or

-enabled libmodplug        && require libmodplug libmodplug/modplug.h ModPlug_Load -lmodplug
+enabled libmodplug        && require libmodplug libmodplug/modplug.h ModPlug_Load -lmodplug -lc++


I have tested with Mac OS X.  Both of them (adding -lstdc++ or -lc++ to enabled libmodplug line) result in good.  I can build ffmpeg fine.  

I think either of them should be added to ffmpeg compile script.  How do you think?
