NCARG example compilation problems

Hello,
i'm new to ncarg. I've downloaded ncarg
(ncl_ncarg-5.0.0.Linux_x86_64_gcc4.tar.gz) from the
site,and installed it to 64 bit Linux server (uname
shows x86_64 x86_64 x86_64 GNU/Linux), to my local
folder.
We use gcc version 4.1.1 20060525 (Red Hat 4.1.1-1).

I'm trying to compile example file vc01c.c from
https://www.nacs.uci.edu/dcslib/ncarg/ngdoc-4.1/ng4.1/qsg/exampletable.html
, and i always got errors like these:

using gcc:
 make
gcc vc01c.c -g -O0 -Wall -o vc01c
-I/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include
-I/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include/ncarg/hlu
-L/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/lib
/tmp/cceXGZD3.o: In function `main':
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.c:64:
undefined reference to `cos'
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.c:65:
undefined reference to `cos'
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.c:73:
undefined reference to `NhlInitialize'
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.c:79:
undefined reference to `NhlRLCreate'
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.c:80:
undefined reference to `NhlRLClear'
......

or, using g++
make
g++ vc01c.cpp -g -O0 -Wall -o vc01c
-I/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include
-I/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include/ncarg/hlu
-L/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/lib
/tmp/ccz68Nhy.o: In function `main':
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.cpp:73:
undefined reference to `NhlInitialize()'
/top/students/GRAD/ECE/ltolstoy/home/workspace/vector/vc01c.cpp:79:
undefined reference to `NhlRLCreate(NhlRLType_)'
......
Make file that i used looks like this:
include_dir1=/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include
include_dir2=/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include/ncarg/hlu
lib_dir1=/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/lib

ccops=-g -O0 -Wall
all:
        g++ vc01c.cpp $(ccops) -o vc01c -I$(include_dir1)
-I$(include_dir2) -L$(lib_dir1)

It seems that compiler couldn't find header files from
include directory, even i wrote all the pathes there.

On
http://www.atmos.ucla.edu/~fovell/AOS180/contourex.html
i found an example which was compiled with ncargcc, it
doesn't work either:
ncargcc vc01c.cpp
gcc -DSYSV -D_POSIX_SOURCE -D_XOPEN_SOURCE
-DByteSwapped -DNeedFuncProto -fPIC -ansi -O vc01c.cpp
-L/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/lib
-L/usr/X11R6/lib64
-I/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include
-lncarg -lncarg_gks -lncarg_c -lg2c -lgcc -lm -lX11
-lXext
/usr/bin/ld: cannot find -lg2c
collect2: ld returned 1 exit status

When i try to start this example with ng4ex vc01c, it
doesn't work either:
NCAR Graphics High Level Utility C Example <vc01c>

  Copying vc01c.c
  Copying vc01.res

Compiling and linking...
gcc -DSYSV -D_POSIX_SOURCE -D_XOPEN_SOURCE
-DByteSwapped -DNeedFuncProto -fPIC -ansi -O -o vc01c
vc01c.c
-L/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/lib
-L/usr/X11R6/lib64
-I/top/students/GRAD/ECE/ltolstoy/home/workspace/ncarg/include
-I/usr/X11R6/include -lhlu -lncarg -lncarg_gks
-lncarg_c -lX11 -lXext -lg2c -lgcc -lm
/usr/bin/ld: cannot find -lg2c
collect2: ld returned 1 exit status
Executing <vc01c>...

./vc01c: Command not found.

Finished executing <vc01c>...

Even starting ng4ex vc01n (not vc01c!) doesn't work on
some servers! The reason is the same:
 cannot find -lg2c
Just on one of the servers, starting this example like
"ng4ex vc01n" i got the output image.

Is it an package installation problem?
I can't find lg2c library anywhere on my computer,
probably it's not a part of the NCARG NCL package?
Can somebody anvise something? How to compile these
examples?
Thanks in advance,
Leon
