Hi I updated from 19.0 to the current version. I only see the tab "Lumped Components" and when i, for example create a simple Resistot the Software just closes. When lunched from console it says "Warning: QVariant::save: unable to save type 261" and then "Memory access error". I tried reinstalling it multiple Times and also tried to rollback but somehow now the 19 version also has the same problem. Is there some hidden config folder that can cause this?

That is probably because

cd "$srcdir"/$pkgname-${pkgver/s/.}

should be changed to

cd "$srcdir"/$pkgname-${pkgver%_*}

as I suggested in my previous comment. At least, it worked for me.

The package is currently broken:

[...]/qucs/PKGBUILD: line 20: cd: [...]/qucs/src/qucs-0.0.20_rc2: No such file or directory

It should be [...]/qucs/src/qucs-0.0.20-rc2.tar.gz

Hello! I tried to build QUCS 0.0.20-RC2 today making just minor edits to PKGBUILD:

prepare() {
    cd "$srcdir"/$pkgname-${pkgver%_*}
    #patch -p0 -i ../issue710.patch
    # this patch is already incorporated to the 0.0.20-RC2 version

and everything builds and works fine so far. So I suggest upgrading this AUR package to 0.0.20-RC2 version, since there is such official release. Thank you!

@eigengrau I just managed to install it on a fresh version of the system, maybe you need to reinstall Qt4?

This currently fails to build with:

@altazar: I merged your fixes :-)

altazar commented on 2018-06-15 23:06

I propose to merge fix for the bug (original github issue:

I've backport this fix for version 0.0.19 (filename issue710.patch):

And prepare PKGBUILD changes:

Please update AUR with these fixes. They are solve "crash on simulation" issue completely.
