If we wish, we can test it now when we feel confident about the program, we can type make install. We now have a compiled version of the program. In effect, we change to the directory where the source was unpacked and do make-the program’s own make file has the necessary information to build the program.
HOW TO WRITE MAKEFILE FOR C PROGRAM CODE
The source code for the program is compiled. (Many UNIX® program distributions try to work out which version of UNIX® they are being compiled on and which optional UNIX® features are present-this is where they are given the information in the FreeBSD ports scenario). This is to make sure that the source was not corrupted while in transit.Īny changes required to make the source work on FreeBSD are applied-this is known as patching.Īny special configuration needed for the source is done.
The checksum for the source is calculated and compared it with one for a known, good, copy of the source.
HOW TO WRITE MAKEFILE FOR C PROGRAM DOWNLOAD
If it is not, an FTP connection to the URL in MASTER_SITES is set up to download the source. x86 Assembly Language ProgrammingĪ check is made to see if the source code for this port is already on the system.
