erbb build simulator fails to build on arch linux

[nckwntzl]

It appears to be having trouble finding rack.hpp however I checked and the file does exist in ~/eurorack-blocks/submodules/vcv-rack-sdk/include/

Hi @nckwntzl !

Sorry you encountered an error, and thanks for the console output for the error.

I don't have Arch Linux installed so I'll most probably need assistance to solve that problem. Here I would supposed this has something to do with make.

Could you please run make -v and tell me what it returns? Thanks!

here is the output of make -v

Ok, that's a fairly recent version of GNU make. By any chance do you have experience with Makefiles?

[ohmtech-rdi]

Maybe could you please try:

$ cd ~/eurorack-blocks/samples/drop/artifacts/simulator
$ CONFIGURATION=Release make -d install

Then please copy the output here, maybe first as a text file you can put as an attachment to your post.

[nckwntzl]

I attached the output to the original post, as well as the makefile.

[ohmtech-rdi]

That's great, thanks so much.

So in the Makefile:

RACK_DIR ?= ../../../../submodules/vcv-rack-sdk
...
FLAGS += -I$(RACK_DIR)/include
...

And in the output of the make command:

g++ -MMD -MP -std=gnu++2a -Wsuggest-override -fPIC -I../../../../include -I/usr/share/vcvrack/include -I/usr/share/vcvrack/dep/include -DARCH_LIN -fno-gnu-unique -O3 -DNDEBUG=1 -DRELEASE=1 -march=nocona -funsafe-math-optimizations -Wall -Wextra -Wpedantic -Werror -Derb_TARGET_VCV_RACK -Derb_BUFFER_SIZE=48 -Derb_SAMPLE_RATE=48014 -I../.. -I../../.. -c -o Release/home/lethargic/eurorack-blocks/src/vcvrack/BoardGeneric.cpp.o ../../../../src/vcvrack/BoardGeneric.cpp

-I/usr/share/vcvrack/include seems to indicate that you have a RACK_DIR in your environment variables. Can you give it a try and try:

echo $RACK_DIR

I would expect this output:

/usr/share/vcvrack

Is that the case?

In that case could you please inspect the content of /usr/share/vcvrack/include and check if rack.hpp is there? I would guess not, but maybe you could have a file around to tell you which version of vcvrack you have installed there? Thanks!

[ohmtech-rdi]

Ok, so provided you are using this Pacman package, it has this profile.sh file that get installed here so at your system level.

I'm not sure what to think about it, since the official VCV Rack repo is counting on include to be there.

So that seems a bit a package mistake to me.

[ohmtech-rdi]

One workaround would be to override RACK_DIR, for example please try the following from the drop sample folder:

RACK_DIR=~/eurorack-blocks/submodules/vcv-rack-sdk erbb build simulator

Does it work?

[nckwntzl]

There are 3 packages in the AUR, I tested two and one of them seems to only partially populate /usr/share/vcvrack while the other does not have that directory at all. I am now trying the package that builds from git, I will see where that takes me.

agreed that it is an issue with the packages, especially considering the different behavior between them.

I will test this after testing the build from git.

[nckwntzl]

Overriding RACK_DIR did solve one problem, however I am still having errors with the build. Attached is the output output.txt

FYI I am on gcc 12.2.1

[nckwntzl]

using the following

as well as adding #include <cstddef> to include/erb/detail/DoubleBuffer.h got the build to work on gcc 12.2.1 under arch linux. I am closing this issue since everything was due to my build environment.

[ohmtech-rdi]

Ok great, thanks. About size_t, it's because we should use std::size_t and I guess gcc 12.2.1 is now enforcing it. I'll make a separate issue for that, because this is not because of your build environment, but our code is not fully standard compliant.

Thanks again for providing the outputs so we could solve this problem.

• For reference #477

[ohmtech-rdi]

@nckwntzl FYI:

• 478

This exhibited the same gcc errors, so I could correct them and ensure CI now checks for them.
