my libraries condiction: mesa 2.6, xform 0.99, XFree86 3.3.2.3, linux RH 5.2

when I am compiling with xforms and mesagl together using g++ -O0 ...(other options)
it says
/usr/lib/libMesaGL.so: undefined reference to 'XShmDetach'
/usr/lib/libglut.so: undefined reference to 'XGetExtensionVersion'
.
.
.

what happen?

if I get rid of -L../lib -glut -lMesaGLU -lMesaGL when I am linking the object files.
it compiles well. however, when I am trying to run the execute file, like ./a.out
it would say:
Sorry, no matching visuals found.
What is this? A palm pilot?

what should I do? should I upgrade the mesa2.6 to mesa3.2? (since I saw missing 'XGetExtensionVersion, is it a hint?)

Thankx.
From Alan.

Maybe you forgot some other X library?
these are the lib I link with:

-lglut -lGLU -lGL -lm -lX11 -lXext -lXmu

you might want to change -lGLU and -lGL to -lMesaGLU and -lMesaGL.

my compile commands are:
$g++ -c -I../include -O2 -I/usr/X11R6/include -I../FORMS File1.cpp
(same things for File2.cpp, File3.cpp ...)
$g++ File1.cpp File2.cpp ... Filex.cpp -o a.out -L../lib -lglut -lMesaGLU -lMesaGL -lm -L../FORMS -lforms -L/usr/X11/lib -L/usr/X11R6 -lX11 -LXext -lXmu -lXt -lXi -lSM -lICE
$./a.out

it says:
Sorry, no matching visuals found.

recall that I copied from what MesaGL's and xforms's Makefiles. Those two Makefiles works fine in each individuals.

the File1.cpp .. Filex.cpp works well in Unix system under sgi O2 machine because they are my class project.

I original thought I have too many options. so I tried the following shortest one:
$g++ -c File1.cpp
$g++ -c File2.cpp
$...
$g++ -c Filex.cpp
$g++ -o a.out -L../FORMS -lforms -L/usr/X11/lib -lX11

it compiles fine as the longer one, but the result is the same as before:
Sorry, no matching visuals found.

I wonder if it's my vedio card's problem, or the version of the X11(3.3.2.3), MesaGL(2/6), or Xforms(0.89)'s problems.

what does "matching visuals" mean?

did I miss any options I shouldn't miss?
well, it compiles well; it's not my codes' problems. I have focus on it for a long time but I have no clue what is going on.

can somebody help me?
Thankx very much.
From Alan.
