I'm having a hard time compiling a plugin (softhddevice) for the video disk recorder software (vdr). Unfortunately the last official version of the plugin was published back in 2013 and even worse it has to be compiled against ffmpeg. The last working version of ffmpeg was 2.8.x, patches should make it work with 3.5.x (if you can find them). It's definitely not working with ffmpeg 4.x So my thought was to forget about all the trouble with different versions and compile the plugin against a static built and working version of ffmpeg. That was the quickly found plan, but the implementation is more than difficult if you are not used to deal with makefiles. I tried to copy parts of the makefile(s) of tvheadend (which btw does exactly what I have in mind) that simply adds the .a files to the linking command. But without success. I know that there's the possibility to tell pck-config to use static libraries, but I have no glue where exactly in the makefile I have to insert this command and how I can force pkg-config to search within the ffmpeg directory. I hope someone can push me in the right direction. Thanks in advance Alex

extract_font_range(3alleg4) Allegro manual extract_font_range(3alleg4)NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
FONT *extract_font_range(FONT *f, int begin, int end)
DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this
function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the
font. Example:
FONT *myfont;
FONT *capitals;
FONT *fontcopy;
...
/* Create a font of only capital letters */
capitals = extract_font_range(myfont, 'A', 'Z');
/* Create a copy of the font */
fontcopy = extract_font_range(myfont, -1, -1);
...
destroy_font(capitals);
destroy_font(fontcopy);
RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
to avoid memory leaks.
