I downloaded and try to installed the package "wfconvert" from this link . but I got some error.

here what I did:

1. copy the wfconvert folder in root "/"


2. 
   

   cd /wfconvert/build/

   
   
   

   root@geant4:/wfconvert/build# cmake ..

3. 
   

   make command

   
   
   

   root@geant4:/wfconvert/build# make

I don`t know what to do!

here is my cmath file list:

Please help me.

I would suspect corrupt installation of development tools or something like that. First thing I would do is re install build package

sudo apt-get purge build-essential

sudo apt-get install build-essential

If the problem still persists post it back

Just curious: How did you install GCC 4.8? I have 13.04 and it have 4.7.3
So that might be an issue if was not done properly!

Is libm automatically linked too, while compiling ?

libm is for compiler g++ and is automatically linked. If you use gcc as compiler you need to link manually with math.h

I found this link here about different compilers generally :

https://stackoverflow.com/questions/1033898/why-do-you-have-to-link-the-math-library-in-c

By the way - there is http://boost.org

You could compile and include with boost-libraries too.

With gcc it looks this:

gcc example.c -o example -lm   

for more precise compiling (with debugging output in case of failures) you do this:

gcc -ggdb -Wall example.c -o example -lm

lm is here the linking with the math-library of gcc (there is #include math.h at the beginning of example.c).
