I just discovered that the K3 has /lib/libm.so.6, which is needed when you use math functions in "#include <math.h>", but it is missing the libm.so symlink needed to use the "-lm" option in tcc to link in the math library. Now I am curious how many other libraries on the K3 are missing their "generic" symlink. This is not a problem on the K5(touch), where linking to the math library is not a problem.

I suppose my tcc installer needs to create any missing library symlinks on the K3.

EDIT: After doing the following commands, my K3 can now link the math library using "-lm":

cd /usr/lib
mntroot rw
ln -s /lib/libm.so.6 libm.so
mntroot ro

It would be nice to know what other libraries will be a problem for each of the different kindle models. I could do the above steps for any missing symlinks during the tcc install process. I suppose I can start with the math library, and worry about the others later. I will post kindle-tcc-1.4.tar.gz soon (after I add a fix for the missing math symlink on some kindles).
