Compiling on Ubuntu 19.04

[mluds]

Hello, I'm trying to compile this on Ubuntu 19.04:

I've installed the AVR tools/libraries:

sudo apt install binutils gcc-avr avr-libc avrdude

And have these versions of avr-g++ and make:

~/code/shruthi-1> /usr/bin/avr-g++ --version
avr-g++ (GCC) 5.4.0

~/code/shruthi-1> make --version
GNU Make 4.2.1

I also updated avrlib to use the correct path:

~/code/shruthi-1/avrlib> which avr-g++
/usr/bin/avr-g++

~/code/shruthi-1/avrlib> git diff
diff --git a/makefile.mk b/makefile.mk
index 3c1f5be..7a84990 100644

Then I run make and get this error:

make: *** [avrlib/makefile.mk:95: build/shruthi1/part.o] Error 4

It seems to be an issue with patch_ being defined here: https://github.com/pichenettes/shruthi-1/blob/master/shruthi/part.h#L216

Any ideas what could be wrong?

[pichenettes]

This seems to be unrelated to the Shruthi code itself, but an error in the compiler itself.

Anyway, the Shruthi-1 codebase is so CPU and space constrained that it is only guaranteed to work with avr-gcc-4.3.3. Any other version will generate slightly different code that might not fit in the 64k of Flash memory available on the ATMega.

Thanks! For anyone wondering, I got it to compile (yet to test) by doing the following:

1. Download Ubuntu 10.04: http://old-releases.ubuntu.com/releases/10.04.0/ and run in Virtualbox or VMware.
2. Edit /etc/apt/sources.list and change all instances of us.archive with old-releases (to get package updates).
3. sudo apt-get install git-core gcc-avr avrdude avr-libc
4. Clone the source with --recursive for the submodules.
5. Run make

This uses avr-g++ 4.3.4, so hopefully it gives the right output.

Thanks for all the tips, @mluds ! After a lot of crazy nonsense I got this working on Ubuntu 10.
After makeing, the resulting firmware is 65396 bytes, which is above the recommended limit of 64512 :(

I wonder if it's because of using 4.3.4 rather than 4.3.3?

@pichenettes, is there anything a desperate maniac could manually trim out of the source files to cut the size down while keeping it functional? It seems like getting a working version of 4.3.3 running is super complicated but also the only viable way to flash this thing at this point. Any ideas?

Quick update: I've managed to downgrade to 4.3.3.
After running make clean and verifying that the build process re-ran properly, it still looks like the file is over the size limit:

(screenshot above shows the version of avr-g++, and this path is the one used in the makefile for the tools path)
