Clubcos is my hand-made operating system, which will be used for my os-dev lecture.
You can clone Clubcos like this:
$ git clone http://github.com/dlarudgus20/Clubcos.git
GitHub Page is available. Also doxygen documentation for Clubcos source is available.
### LicenseClubcos is under The BSD (2-Clause) License.
### Prerequisitesmake
binutils, which is cross-compiled for i686-pc-elf
gcc upper 4.8.x, which is cross-compiled for i686-pc-elf
nasm upper 2.11
python
qemu (for make run)
bochsdbg (for make run_bochs)
Notice: Before you try to build, you must build cross-compiler
And you also need qemu for make run, and bochsdbg for make run_bochs
First, clone this repository:
git clone https://github.com/dlarudgus20/Clubcos.git
Second, just make it!
make
Notice that default configuration is Debug mode, so you should specify configuration if you want to build Release mode.
make CONFIG=Release
If the cross-compiler is not in PATH environmental variable, you should specify its path.
# Notice that it MUST contain target triplet prefix (e.g. i686-pc-elf)
make TARGET_PREFIX="/usr/local/cross/bin/i686-pc-elf"
Before building, you need cross compiler for i686-pc-elf to build Clubcos.
First, install prerequisites for gcc and binutils. links
Especially, you need these:
bison
flex
libgmp-dev
libmpfr-dev
libmpc-dev
# optional
isl
cloog
Download source of gcc and binutils. And, follow this script to build.
(In my example script, I assume that both gcc and binutils are in /usr/src.)
export TARGET=i686-pc-elf
export PREFIX=<where-to-install-cross-compiler>
export PATH="$PREFIX/bin:$PATH"
cd /usr/src
mkdir build-binutils
cd build-binutikls
../binutils-x.y.z/configure --prefix="$PREFIX" --target=$TARGET --disable-nls --disable-shared
make
make install
cd ..
mkdir build-gcc
cd build-gcc
../gcc-x.y.z/configure --prefix="$PREFIX" --target=$TARGET --disable-nls --enable-language=c --without-headers --disable-shared
make all-gcc
make all-target-libgcc
make install-gcc
make install-target-libgcc
