Hello, I am a newbie. I am currently implementing some interprocess functionality into my program which must reside on both a windows and linux operating system. I have completed the windows integration ( this is where the code originally resided) and am now moving it to the linux platform : Debian 4.1.1-21 -- I have created my makefile and am using gcc version 4.1.2. I get the following output on my make and cannot figure out how to fix this issue: GNU C++ version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) (i486-linux-gnu) compiled by GNU C version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21).
