Compiling a dependency on a missing git package results in an error when compiling the latest version. The extra build test from devtool is used.

Thanks @anatolik

abougouffa, I added you as a com-maintainer. Please feel free to make the changes to the packages.

Hello,

First, as of this year, the git packages need to have git+https://REPO, the old git://REPO do not work anymore.

The package needs an update, as of commit DSView@7b94e61be the libsigrok4dsl-git and libsigrokdecode4dsl-git cannot be compiled (they deleted autogen.sh and Make related files), it seems that they updated the CMake files to search for these components in the project root.

This patch seems to work with the current version, it is a single package setting which will install related libsigrokdecode4dsl stuff.

dsview development practices are one of the most confusing I've ever seen.

imi415 commented on 2022-04-13 23:51 (UTC)

It appears that someone working on this project is using dev-tai as their development branch, which contains bugfixes and new features, could we switch the upstream branch to this? The current master branch causes crashes due to an libusb bug, which was fixed in (https://github.com/DreamSourceLab/DSView/issues/473#issuecomment-1041362934)

Added issue to upstream project.

FuzzyCheese, could you please send your finding to the upstream project?
