RBuild

Simple declarative buildsystem for C/C++, supports windows and linux out of the box, but should be trivial to port to other unix-like platforms.

It is built to be as simple as viable, and as such it doesn't handle:

• Dependency discovery
• Pre/Post build steps
• etc

It does support:

• Incremental Building
• Exact linking order, if necessary
• Specifying sources either per-file or per-folder ( as white/blacklist )
• Multiple targets ( be them debug/release/etc )

Using

The command-line arguments the program accepts are:

ARGUMENT	DESCRIPTION
-help	display help message
-file=[json file]	specify which file it uses as the project file, if no file is specified it uses "[current folder name].json"
-rebuild	rebuild project from scratch, ignore already-built object files
-verbose	print whole command line of executed compilers/linkers
-gcc_override=[compiler]	use specified compiler instead of gcc
-gxx_override=[compiler]	use specified compiler instead of g++
-clang_override=[compiler]	use specified compiler instead of clang
-clangxx_override=[compiler]	use specified compiler instead of clang++
-failexit	exit at first fail
-ignore_warnings	don't prompt, always continue if there are warnings
-num_jobs=[num_jobs]	execute [num_jobs] compilations in parallel, use auto to perform as many parallel compilation as there are processors in the system
-version	display current version
-filetime_nocache	don't cache file write times
-incremental_build_exclude_system , ‑MMD	exclude system headers when generating dependency files
-static	link program statically ( may not work depending on which libraries are used, which linker is used, and how the project's json file is structured )
-clean	remove obj/ and tmp/, requiring next build to be a full rebuild

The layout for the json file is specified in info/json_layout.txt, and the documentation for each field is at FORMAT.md.

Building

This project doesn't have any dependencies other than a recent-enough version of gcc (with C++20 support), and it can be built either with itself, or via a shell script.

Linux

Option 1 (shell script)

• run build.sh to build it
• optinally run install.sh to add it to your path

Option 2 (codeblocks)

• open the RBuild.cbp project file in codeblocks, and compile it
• optionally manually add it to your path

Option 3 (itself)

• run RBuild on the project folder, if the project is in a folder named RBuild, or RBuild -file=RBuild.json if the project is in a different folder
• optinally run install.sh to add it to your path

Windows

Requires MinGW

Option 1 (batch file)

• run build.bat to build it
• optionally manually add it to your path

Option 2 (codeblocks)

• open the RBuild.cbp project file in codeblocks, and compile it
• optionally manually add it to your path

Option 3 (itself)

• run RBuild on the project folder, if the project is in a folder named RBuild, or RBuild -file=RBuild.json if the project is in a different folder
• optionally manually add it to your path
