０から作るソフトウェア開発　ダウンロード　TRON (T-Kernel for x86)

First of all

T-Kernel is originally implemented and released by TRON Forum. It is a real-time operating system based on T-Kernel specifications which are specified by TRON Project. For more information about TRON and T-Kernel, visit and see TRON Forum web site.

Running T-Kernel for x86

1. Download an iso image file from the following repogitory path. TRON/srcpkg/tkernel_source/kernel/sysmain/build_t2ex/std_x86/grub_rescue.iso

2. Set up your VirtualBox to boot from grub_rescue.iso cd-rom image.

To build the kernel from sources

Configure environment variables

Before build the kernel, you have to set up the following environment variables.

• BD

  Set directory path name in which T-Kernel source code are stored.

  Ex. if you store the kernel sources in /home/user/srcpkg/tkernel_source directory, then set "/home/user/srcpkg/tkernel_source" to BD variable.

• GNU_BD

  Set bin directory path name in which cpp and objcopy are installed.

  Ex. if you install cpp and objcopy in /usr/bin directory, then set "/usr" to GNU_BD variable.

• GNUX86

  Set bin directory path name in which gcc are installed.

  Ex. if you install gcc in /usr/bin directory, then set "/usr" to GNUX86 variable

For example, you can append the above configurations to your .bash_profile at last line as follows.

~/.bash_profile

export BD=/cygdrive/c/Users/Nina/Desktop/Documents/tron/T-Kernel2.0/srcpkg/tkernel_source

export GNU_BD=/usr

export GNUX86=/usr

edit makerules.sysdepend

Currently, the kernel sources are expected to be built on Cygwin with linux-cross-compiler. So, if you want to build the kernel on your linux, then you have to edit makerules.sysdepend file.

makerules.sysdepend file is found at the following path.

srcpkg/tkernel_source/etc/sysdepend/std_x86/makerules.sysdepend

You may edit the following items.

• CC

  Edit CC := $(GNUX86)/bin/i686-pc-linux-gnu-gcc to CC := $(GNUX86)/bin/gcc

• CXX

Edit CXX := $(GNUX86)/bin/i686-pc-linux-gnu-gcc to CXX := $(GNUX86)/bin/gcc

• AS

Edit AS = $(GNUX86)/bin/i686-pc-linux-gnu-as to AS = $(GNUX86)/bin/as

• LD

Edit LD = $(GNUX86)/bin/i686-pc-linux-gnu-ld to LD = $(GNUX86)/bin/ld

• AR

Edit AR = $(GNUX86)/bin/i686-pc-linux-gnu-ar to AR = $(GNUX86)/bin/ar

• NM

Edit NM = $(GNUX86)/bin/i686-pc-linux-gnu-nm to NM = $(GNUX86)/bin/nm

make the kernel

To make the kernel, you can run make command in kernel/sysmain/build_t2ex/std_x86 directory.

For example,

$ cd srcpkg/tkernel_source/kernel/sysmain/build_t2ex/std_x86

$ make

make the bootable ISO image (grub_rescue.iso)

After the kernel is successfully compiled, make the bootable ISO image.

For example,

$ make cd

Finally you can see the grub_rescue.iso in current directory and boot it on VirtualBox!
