mOS in Ubuntu

sxmxr opened this issue 4 years ago · 34 comments

Hi @MQuy, I and my teammates have successfully installed GCC Cross-complier using that Wikipedia page which was mentioned in one of the earlier issues. (https://wiki.osdev.org/GCC_Cross-Compiler) I have installed i686-elf-gcc successfully(Screenshot-1) Now while installing the whole project, using the mentioned shell scripts in the read.me, I got error like, "./create_image.sh: line 6: hdiutil: command not found".(Screenshot 2). My host OS is Windows 10 and I'm using Ubuntu 20.04 within the virtual box.

@sxmxr if you check out master branch and run like this I think it will work

$ cd src
$ ./create_image.sh
$ ./build qemu iso

Answer 2 · 2020-10-24T10:48:05.000Z

you shouldn't need to change anything, I changed create_image.sh to support ubuntu if you pull master.

To build toolchain

$ cd src
$ cd toolchain && ./build.sh

Run

$ cd src
$ ./create_image.sh
$ ./build.sh qemu iso

Answer 3 · 2020-10-24T10:50:49.000Z

@MQuy Thank you for your response. ./create_image.sh was compiled successfully but while running "./build qemu iso" command I'm getting this error.

Answer 4 · 2020-10-24T10:52:50.000Z

can you send a screenshot if you run the command below

cd src/kernel && make clean && make

Answer 5 · 2020-10-24T10:55:09.000Z

@MQuy I compiled that command and here what I got :

Answer 6 · 2020-10-24T11:05:33.000Z

hum, what is your ubuntu version? my guess is the latest gcc have breaking changes, could you try with gcc 9.x

Answer 7 · 2020-10-24T11:16:49.000Z

hum, what is your ubuntu version? my guess is the latest gcc have breaking changes, could you try with gcc 9.x

@MQuy My ubuntu version is 20.04. So I have to make cross compiler again. Right?

Answer 8 · 2020-10-24T11:17:35.000Z

yes, try with gcc 9.x :)

Answer 9 · 2020-10-24T11:41:06.000Z

yes, try with gcc 9.x :)

Thank you, for your response. I'll get back to you in case of any queries.

Answer 10 · 2020-10-27T09:32:58.000Z

I have installed gcc 9.1 cross compiler and tried to build file in toolchain but I'm getting this error while running this command "cd toolchain && ./build.sh"

Answer 11 · 2020-10-28T09:58:29.000Z

@MQuy Ubuntu isn't working for me. So I am thinking to install Mac-OS on VirtualBox and will run it. Is it possible?

Answer 12 · 2020-10-28T10:08:12.000Z

can you give more details about the error above? I think Ubuntu is better in long term

Answer 13 · 2020-10-28T10:39:16.000Z

@MQuy Here are the steps I have followed, Please correct me if I'm wrong :

Followed steps of https://wiki.osdev.org/GCC_Cross-Compiler and installed GCC 9.1.0 and Binutils 2.32, so basically activated new cross-compiler.
Downloaded the source code of mOS and moved to src directory.
Then I entered this command "$ cd toolchain && ./build.sh"
After that I got the above error.

Answer 14 · 2020-10-28T11:36:51.000Z

could you try to open build.sh and modify these variables to fit in your case and run again?

PREFIX="$HOME/opt/cross"
TARGET=i386-mos
# SYSROOT cannot locate inside PREFIX
SYSROOT="$HOME/Projects/mos/src/toolchain/sysroot"
JOBCOUNT=$(nproc)

Answer 15 · 2020-10-28T15:06:14.000Z

@MQuy Thank you for your response. Just to confirm, according to this (https://wiki.osdev.org/GCC_Cross-Compiler) my target variable will be TARGET=i686-elf. Right? or do I have to change target to i386-mos?
P.S. I have changed the SYSROOT.

Answer 16 · 2020-10-28T15:57:52.000Z

No, only SYSROOT, make sure that folder exist

Answer 17 · 2020-10-28T18:50:48.000Z

@MQuy Thank you for your help. ToolChain is compiled successfully. Now while compiling the "./create_image.sh" I'm getting this error.

Answer 18 · 2020-10-28T18:58:04.000Z

you should umount like this first

sudo umount /mnt/mos
sudo rm -rf /mnt/mos

Answer 19 · 2020-10-28T19:01:50.000Z

you should umount like this first

Yess.. I have

done the same but lead to this error :/

Answer 20 · 2020-10-28T19:04:40.000Z

can you comment this line from ./create_image.sh and run it again

# cd ports/figlet && ./package.sh && cd ../..

Answer 21 · 2020-10-28T19:05:18.000Z

@MQuy Sorry for the inconvenience I have caused. But I'm totally new to these topics and my faculty has given a project to implement a new feature in existing features. I'm planning to implement SMP and 2 level paging.

Answer 22 · 2020-10-28T19:07:34.000Z

no np, feel free to ask, I will answer when I am online ;)

Answer 23 · 2020-10-28T19:08:25.000Z

After compiling "cd ports/figlet && ./package.sh && cd ../.."

Answer 24 · 2020-10-28T19:09:48.000Z

did you remove that line? you don't need that program to run

Answer 25 · 2020-10-28T19:15:43.000Z

Yes, I commented it.
And here is the results.

After compiling "./create_image.sh"
After compiling "$ ./build.sh qemu iso"

Answer 26 · 2020-10-28T19:16:56.000Z

you don't have logs folder

$ cd src && mkdir logs

Answer 27 · 2020-10-28T19:20:29.000Z

@MQuy After creating it, I run that again and I got this screen.

Answer 28 · 2020-10-28T19:21:36.000Z

Answer 31 · 2020-10-28T19:25:43.000Z

Finallyyyyy!

Answer 32 · 2020-10-28T19:27:11.000Z

So whenever I make changes, I have to run "$ ./build.sh qemu iso" , $ cd src && gdb isodir/boot/mos.bin, target remote localhost:1234, c" commands. Right?

Answer 33 · 2020-10-28T19:28:09.000Z

if you make changes to src/apps or src/libraries you have to run ./create_image.sh

Answer 34 · 2020-10-28T19:31:12.000Z

Ohh, Okay. Thank you so much @MQuy for your quick responses. Now I'll analyze the whole project, and will try to implement the capstones for the project.
