Arch Linux User Repository

The latest tag of this project (0.0.20) still depends on qt4 which is only available in AUR now.
If you really need to build this (and also qt4) I recommend editing the qt4 package PKGBUILD and adding -j`nproc` arg to the make call - otherwise it will take a long time build.

0.0.20 also seems to be the last version of qucs before qt5 (see the archival in the tagged commit message): https://github.com/Qucs/qucs/commit/9ca02d8dd7c4bc426a09e4217977ad0519f16f2e

I get this error when trying to build

When I added -DCMAKE_POLICY_VERSION_MINIMUM=3.5 it built just fine, however I cannot run simulations as I get the following error

Cannot start /usr/bin/qucsator (No such file or directory)

Thanks Lacsapix.

Regarding "qucs without qucsator", it's in the qucs/develop_filtered branch, see [0]. I don't know if it works, but If there is a consensus, I could

a) change the qucs default branch to develop_filtered b) simply replace the develop branch, and archive the current one.

This will break the qucs-git package [1] one way or another.

Let me know what you think.

I can confirm that using the qucsator-git package works.

Because there is no "qucs without qucsator" package as of yet. You do need to manually overwrite the existing qucsator package. (pacman -U --overwrite "*" {YOUR QUCSATOR_GIT BUILD.pkg.tar.zst})

The "Simulator crashed" is a Qucsator bug and probably the one that has been fixed in git. Try the qucsator-git package, or try Gnucsator instead.

there isn't much activity

True -- Qucs 0.0.20 depends on Qt3/4 and nobody is interested to work on it.

Maintainers are invited to send patches. The patch we need removes everything but the "qucs" subdirectory from the repo.

Hey, there isn't much I can do, this sounds like upstreams (https://github.com/Qucs/qucs) problem. QUCS is also getting old and not really maintained, there isn't much activity in the repo so it's expected stuff will start to break more and more.

Hi! I've installed the latest version of qucs from AUR with yay in EndeavourOS and every time I launch the simulation it says "ERROR: Simulator crashed!". Is it possible that the qucsator package is broken? Also, qucs doesn't show the components preview when placing them.

fjdebruijn, crash on adding/selecting a component was fixed for me by updating qt4 to the latest version. qt4 is an AUR package so it won't upgrade automatically.

fjdebruijn, I will look at it
