Nore

No More than a C build system for clang, gcc and msvc.

Configuration

There are no installation process just setup bash and make environment.

The most simplest way to configure is into your C application directory and run

bash <(curl https://raw.githubusercontent.com/junjiemars/nore/master/bootstrap.sh)

then done.

On Windows, because there are no bash by default, so We need install Git Bash first, and select 'unix compatible tools' when installing. Run bash in any CMD or MSYS, then

bash <(curl https://raw.githubusercontent.com/junjiemars/nore/master/bootstrap.sh)

In this process, the bootstrap.sh will configuration bash environment and install GNU Make if there hadn't installed yet.

Getting start

There are an example at https://github.com/junjiemars/nore-hi,

$ git clone --depth=1 https://github.com/junjiemars/nore-hi.git

The nore-hi directory look like this:

.
├── LICENSE
├── Makefile
├── README.md
└── hi
    ├── Makefile
    ├── hi.c
    └── version

After configuration, it's look like:

.
├── LICENSE
├── Makefile (generated by Nore)
├── README.md
├── configure (generated by Nore)
└── hi
    ├── Makefile
    ├── hi.c
    └── version

Now, a story of classic workflow begins:

• compose a Makefile, here we use hi/Makefile;
• ./configure --has-hi --prefix=/tmp, after configured, the structure of working directory looks like:

.
├── LICENSE
├── Makefile
├── README.md
├── configure
├── hi
│   ├── Makefile
│   ├── hi.c
│   └── version
└── out (generated by Nore)
    ├── Makefile (generated by Nore base on your hi/Makefile)
    ├── autoconf.err
    ├── bin
    ├── conf
    ├── inc
    ├── lib
    ├── log
    ├── nore.h (generated by Nore)
    ├── pid
    └── tmp

• make
• make install

The out/Makefile be generated by Nore base on hi/Makefile

# hi/Makefile

hi_binout := $(bin_path)hi$(bin_ext)

# note: hi target has same name with the directory
hi: $(hi_binout)
hi_test: hi
	$(hi_binout)

$(hi_binout): $(src_path)hi.c 
	$(CC) $(CFLAGS) $(INC) $^ $(bin_out)$@

All elements of hi/Makefile can be found in out/makefile:
