DCP - Copy and Profile files and directories

The project has been refactored to use a more canonical build process. To do so, you now just need to configure and run make.

./configure
make
make install

Note: You will probably need to run make install as root.

You will still need gengetopt, as it's used to generate a command line parser for the application, but now you will be explicitly told so during the configuration process if you do not have it. If the configuration process succeeds, gengetopt was successfully found in your path.

Here is a breakdown of the libraries you will need to successfully build this application.

Library Name	Description	Version Tested
libcrypto	From OpenSSL	-
libdb	Berkley DB	5.3.28-4
gengetopt	Command line args parser generator	2.22.6-7

Configuration

The build system refactoring process is still ongoing, so the configuration script is not as robust as it could be. It does, however, successfully build on gcc, clang, and Intel's icc compiler.

Configuration is pretty standard. You can modify the build as usual through the CFLAGS, CPPFLAGS, and LDFLAGS as always, just keep in mind that currently the compiler set by CC is used as the linker driver, so whatever settings you set in LDFLAGS right now must play well with whatever C compiler you choose to use. Also, any additional libraries you wish to link against should be set via the LIBS variable, not LDFLAGS.

If you run into any weird errors on a rebuild, the safest bet is to run make distclean then run ./configure again to regenerate the header files for the build.

You can not yet directly install it using the usual make install command, however. This is a work in progress, as the entire project had to be refactored.

You should now be able to successfully install dcp after building, by way of the usual make install command. It does not yet use install, but rather simply moves the newly built binary into the destination directory set during configuration. The default prefix is the usual /usr/local and can be configured using --prefix=/usr, or whatever you so wish.

You can also uninstall the binary by running make uninstall as root, and the binary installed by make install will be removed.

Supported Compilers

This is a breakdown of the compilers on which the current version of the project has been tested. The GCC trunk branch was current as of 9:30 PM Eastern time, June 4th, 2019. All of the builds were tested on an x86-64 Arch Linux system. If you run into any issues in a different environment, be sure to include that in the issue description so we can spin up a VM with the right OS.
