ericfont: No need to downgrade libgit2. You just need to rebuild Fritzing after the libgit2 update. This happens regularly.

@Metaphysix: Thanks a lot for your analysis! This will be fixed in 1.0.7-2.

Update: Installing ttf-droid does not fix the segfault for me. I think ggilestro is right and this is a Qt bug. We'll have to wait for the Qt update.

Hi, on a clean Arch system without ttf-droid installed, Fritzing 1.0.7 from this package crashes (SIGSEGV in Qt6Svg/QFontEngineFT::loadGlyph) as soon as I hover a part in the Parts bin — the Inspector tries to render an icon for an SVG that references Droid Sans and the missing-font path crashes the renderer.

The fritzing-parts library references Droid Sans (and DroidSans, Droid Sans Mono) in hundreds of SVGs. ttf-droid is in extra/, so adding it as a hard depends (or at least optdepends=('ttf-droid: text rendering in part SVGs')) would prevent this for everyone.

Reproducer on a system without the font:

1. pacman -Rns ttf-droid (if installed)
2. Fritzing → hover any basic part → segfault
3. coredumpctl info $(pidof Fritzing) → stack ends in cachedIconFromSvg → QSvgText::draw_helper → QFontEngineFT::loadGlyph

Thanks for maintaining the package!

Re: SIGSEGV when hovering over certain parts (resistor, transistor, etc.)

This crash affects everyone on Qt 6.10.x and 6.11.0. It's a Qt bug, not a Fritzing bug.

Root cause: QFontEngineFT::loadGlyph() in qt6-base crashes when FT_Render_Glyph() fails (error 0x62 = raster overflow). The error is logged (render glyph failed err=62...) but execution continues to memcpy from slot->bitmap.buffer which is NULL after the render failure, causing a SIGSEGV. This is triggered by certain SVG tooltip previews containing text elements that cause FreeType to overflow.

Upstream fix: QTBUG-145310, fixed in Gerrit #724504. Picked to 6.8, 6.10, and 6.11 branches. Will ship in Qt 6.11.1 (expected end of April 2026).

Workaround until 6.11.1: Rebuild qt6-base from the Arch GitLab PKGBUILD, adding one line to prepare():

  git -C $_pkgfn cherry-pick -n 1466f88633b2c29a6159a0c2eacd0c0d6601aa5e                                                                         

Then makepkg -si and add qt6-base to IgnorePkg in /etc/pacman.conf until 6.11.1 lands.

Note on the build: The lrelease-pro path issue has already been fixed by Bevan in the upstream PKGBUILD — just update with yay -S fritzing.

same problem as @Abelkrijgtalles related:

lulzcasz@earth ~> Fritzing QFont::setPixelSize: Pixel size <= 0 (0) QFont::setPixelSize: Pixel size <= 0 (0) render glyph failed err=62 face=0x55e35e218a00, glyph=20 fish: Job 1, 'Fritzing' terminated by signal SIGSEGV (Address boundary error)

im running Arch with KDE.

Hi, I'm running Hyprland, and when I hover over the available core/simulator parts in the sidebar, Fritzing freezes up and crashes while presumably wanting to render some kind of tooltip. Is there any fix for this?

EDIT: This only happens on a very specific set of parts. I've seen it crash on a resistor and a transistor. I've seen it not crash on a standard LED. This is the console output: QFont::setPixelSize: Pixel size <= 0 (0) QFont::setPixelSize: Pixel size <= 0 (0) render glyph failed err=62 face=0x5643593b4670, glyph=21 Segmentatiefout (geheugendump gemaakt) env QT_AUTO_SCREEN_SCALE_FACTOR=0 Fritzing %F Turns out it's a segmentation fault

EDIT: I've also made a GitHub issue

EDIT: They've now closed the issue because I won't pay

@Abelkrijgtalles: Thanks for your message. I updated the PKGBUILD to use the correct symlink to Qt6 release-pro in /usr/bin.

Hi, I don't have lrelease-pro installed, and because of that it won't build. Could you please add the needed package to build dependencies or remove this line? Thank you

EDIT: I see I have it in /usr/lib/qt6/bin/ instead of /usr/lib/qt6. qt6-tools is already added as a make-depend. Adding bin/ to the end works and installs fritzing.

@mozurin: I somehow totally missed your message. Thanks a lot for tracking this down and providing a fix! I included it in version 1.0.6-2.

A small patch was needed to build it correctly with Qt 6.10.1.

ref. https://github.com/qgis/QGIS/pull/64056

I've encountered an issue where the build fails if the build/ directory already exists from a previous build. This happens when rebuilding without a clean build directory.

The fix is to use mkdir -p build instead of mkdir build, ensuring the directory exists without failing. Here's the patch:
