How to compile a file in unix or linux

You'll want to use GCC most likely. There's plenty of documentation on how to use this compiler online, and you can check the man pages as well.

man gcc

Good luck,

Just cd to the directory where the file is
and type

gcc secure_pkt_send_rcv.c

the compiled file will be a.out

so type ./a.out to run the file

Thank u madman559! But after i cd the file and i type in gcc secure_pkt_send_rcv.c
there is error occur.This is the error message:secure_pkt_send_rcv.c:6:error:expected'=', ',', ';','asm' or'_attribute_'before 'receive_secure_packet'

Thank u Pyroflea.I will do some reading about GCC online.This is first time i heard about GCC.I had learned something new.

Its a rather specific file name, and I suspect it is one file that makes up a larger library or program. The commands are correct to compile that one file, but that's not the whole story typically. If that file is part of a software package, there are going to be make scripts and other setup steps that need to be made before the whole thing will work. Simply telling GCC to compile the file without the libraries, headers and definition files setup in the command line would be pointless, hence the errors and warnings you received. Basically GCC doesn't have enough information to compile that code.

In the root directory of the tar.??? you uncompressed should be a file README, or INSTALL etc... that has instructions on how to build and install the package. depending on the build system used, you'll typically have to run some combination of:

./configure && make && make install

If the author(s) of the program have things setup correctly, that will prepare the code to be compiled, compile the program and install it to the desired directories to be accessable to the system. If you get any errors at that stage, you may not have all the required dependencies or there is a bug in the package that needs to be addressed.

Good luck.

If it is a standalone file you may try posting the code in the programming section of the forums.
