Bochs: display library 'sdl' not available

Asked 2020-Sep-06 at 17:26

Recently I've started reading this "book" about OS development (https://littleosbook.github.io/), and I find it great and all that, but I came across a problem while trying to boot up my image in bochs.

At some point the guide about running the operating system in Bochs tells me to create a config file for the emulator. I set every option to what I read.

But when I run the following command,

bochs -f bochsrc.txt -q

it says:

display library 'sdl' not available

The relevant line in the config file is pretty obvious:

display_library: sdl

I don't know what's the problem. I installed both libsdl and libsdl2.0, but it still won't work.

My work environment consists of an Ubuntu 20.04 and a Bochs 2.6.11.

Has anybody faced with this issue? What's the solution?

I ran into this issue when running my code on a Vagrant that had no windows manager installed. I think that a windows manager has to be set up in order for bochs to be able to access the relevant libraries or whatever (don't quote me on that lol). After I reinstalled the following dependencies over this Vagrantfile, I managed to get it to work. It worked even better with bochs-x and x.

I'm following this tutorial to make a simple bare bones 32-bit operating system. I have gotten as far as section 4 where i'm writing to the frame buffer. Basically i'm attempting to create my own println function. Here is the code for my function:

The issues here are not related to your C code but problems in your file loader.s. You have problems with the section names having a colon on the end that becomes part of the section name, and you haven't put the code in the executable .text section.

These lines have extra colons on the section names:

@Margaret Bloom's comment solved my issue. The issue was that a character is 16 bits, and I needed to increment I by 2, but I was increment it by 1, causing it to overlap like this:

Intended: char1Data char1Color char2Data char2Color

Problem: char1Data char2Data char2Color

i386 GNU ld: file not recognized: File format not recognized

Asked 2017-Nov-01 at 01:34

I'm working my way through The Little Book About OS Development, specifically the section on the framebuffer (linked). I'm able to successfully assemble, link, turn into an ISO file and boot pure assembly, but as soon as I try to link a compiled object file for my C code (called from my loader, which was written in assembly), the linker complains. Here's the output:

As it turns out, this was solved by cross-compiling GNU Binutils and GCC together (with the same prefix) on my Mac. I did this according to the instructions here.
