Topic: can we remove the fltk libs?, does flua even use them?

I was looking at the size of flua compared to the size of regular old lua and it's about 3X as large. It looks almost like the portions it uses of the fltk libs were compiled into it. I see we have two libs called

/usr/lib/libfltk-utf8.so.1.1
/usr/lib/libfltk-utf8_images.so.1.1

I removed those two libs (618376 + 56852 = 675228 bytes) and it looked like flua still worked. Do those libs get used by any other programs?

I ran ldd on flua to make sure that it doesn't call those libraries:

dsl@box:~$ ldd /bin/flua
libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40019000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40026000)
libm.so.6 => /lib/libm.so.6 (0x400e2000)
libc.so.6 => /lib/libc.so.6 (0x40104000)
libdl.so.2 => /lib/libdl.so.2 (0x40232000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Flua is just one file, so i assume you're right that it doesn't use any external lua or fltk files. It's possible that those libs are/were used by another application, such as flwriter.

Mikshaw, That's true, but how can you check every applications. I wrote this little script that runs ldd on every file in a directory that has the ELF magic cookie in it's header. I assumed that they would be the only files that needed to be tested. Is that true?

Code Sample

#!/bin/bash

if [ ! -d $1 ]; then
COOKIE=`head -c4 $1`
if [ `echo $COOKIE | tail -c4` = "ELF" ]; then

if ( ldd $1 | grep fltk ); then
echo found in file: $1
fi
fi
fi

I ran this on /bin, /usr/bin, and /usr/X11R6/bin but found no matches. This line works as well to look for matches:

for i in /usr/X11R6/bin/*; do ldd $i | grep fltk; done

FLwriter uses a modified fltk library of which you have found.
Since it is modified, i.e., a non-standard library it is most unlikely that any other app would be using it.
