c programming in ubuntu (undefined reference to `mclWrite_proxy' )

I created a .c project using the cpp command in matlab. (by converting a .m code)

When i tried to compile the code in ubuntu 12.04, i get the following error.

 In function `mclDefaultPrintHandler':
 matching2_main.c:(.text+0x40): undefined reference to `mclWrite_proxy'

can anyone help me to solve this issue?
