Whoa -- the ldglite I produced via libtool is an sh wrapper for .libs/ldglite
produced by ltmain.sh (part of libtool I guess). That's how it's so small! :)
3k seemed awful small to me too -- almost unbelievable. 20k I could believe
easily, 3k and we're talking some ultra-serious optimizations and cuts due to
the OpenGL library.
Anyway, the _real_ executable then is 196483 bytes (similar to what I got
last night with the original make process).
$ strings .libs/ldglite | grep lib
/lib/ld-linux.so.2
libglut.so.3
libSM.so.6
libICE.so.6
libXmu.so.6
libXext.so.6
libXi.so.6
libX11.so.6
libGLU.so.1
libGL.so.1
libvga.so.1
libm.so.6
libc.so.6
__libc_start_main
/home/todd/Mesa-3.1/src-glut/.libs:/home/todd/Mesa-3.1/src-glu/.libs:/home/todd/Mesa-3.1/src/.libs:/usr/local/lib
Both of these command lines
$ ./ldglite cyl.dat
$ .libs/ldglite cyl.dat
from the build directory do the same thing -- the same old white screen.

| (...) Actually I'm not quite as impressed as I was a few minutes ago. I checked the size of the executable in the zip file and it's only 81064 bytes. The bloat we saw was the debugging symbols. You can remove them with this. strip ldglite I now (...) (24 years ago, 26-Jan-00, to lugnet.cad.dev)
