Cannot build without Catch2/cppcodec being available

[daringer]

• Application version: 1.4.2
• Operating system: Arch Linux, latest, 64 bits, kernel version: 5.10.9-arch1
• Device model and firmware version: all (build)
• Connected USB port type: n/a
• Issue occurrency: always

Expected behaviour

It's possible to build w/o Catch2 / cppcodec

Current behaviour

cppcodec and Catch2 not available, leads to the output below during a default build. If cppcodec is available and Catch2 is not, then the build fails due to a missing Catch2.

Steps for reproduction

make sure cppcodec is not available and try to build

This hits me too. Trying to build the app for Debian based systems but get the same error.

Weird because I can build 1.4.1 without issues.

[jeremiah]

I guess the solution is perhaps to include cppcodec in official releases of nitrokey-app. Otherwise, one has to use the git submodule to pull it in or download cppcode separately as cppcode is not packaged for Debian. It's not listed as a dependency in the README either.

[szszszsz]

I am not sure I understand the problem.
@daringer Why do you need that? For general case the Readme clearly states that submodules are required:

• https://github.com/Nitrokey/nitrokey-app#getting-the-nitrokey-sources

@jeremiah Nothing has changed since v1.4.1 though - could you confirm?

Readme indeed is missing dependencies list.

[daringer]

@daringer Why do you need that? For general case the Readme clearly states that submodules are required:

well, the obvious reason is that building without tests might be a nice-to-have.

Generally, revisited this and I believe the issue is simply the source-packaging I was using - you are totally right, the README clearly states the need for sub modules. But for the flatpak release I was using the .tgz provided in "releases" and inside this archive the sub-modules (i.e., cppcodec, but also libnitrokey) are not included.

Means for the git repository itself this is not an issue, but for the source-releases nitrokey-app should either include cppcodec or provide a way to build without it...

@szszszsz The only change from 1.4.1 to 1.4.2 I believe is the addition of bash auto-completion.
