A Linux program that will not start usually fails silently: you click the launcher, nothing appears, and there is no message to argue with. Gerbv is a native Linux application, so the cause is almost never exotic — it is a missing shared library, most often from the GTK 2 runtime it is built on,…
The macOS story starts with good news: Gerbv 2.13.0 is the first release to ship an official macOS build, distributed as a ZIP — there is no .dmg, so do not go hunting for one or download a supposed .dmg from anywhere else. The friction arrives after the download. You extract the ZIP, try to…
You download the Gerbv installer for Windows, double-click it, and instead of an installation wizard you get a blue Windows message saying the PC was protected and an unrecognised app was prevented from starting. That is Microsoft Defender SmartScreen doing its job — and the worst possible responses are the two instinctive ones: abandoning the…
Some files refuse to open in Gerbv for a reason that has nothing to do with your computer, your installation, or the file’s condition. They refuse because they belong to an older generation of the Gerber format — RS-274D — and Gerbv’s support is explicit on this point: it views RS-274X files, and RS-274D files…
There is a particular kind of wrong that only unit errors produce. The board shape is perfect. The proportions are perfect. Every feature is exactly where it belongs relative to every other feature — and the board is twenty-five times too large, or so small it hides under a single pad of the board you…
Drill problems announce themselves in two distinct ways, and separating them is half the diagnosis. In the first, the holes are in the right places but the wrong sizes — every hit looks too large, or too small, or one tool’s holes are sensible while another’s are absurd. In the second, the sizes look plausible…
Few sights undermine confidence faster than layers that do not line up: the mask shifted from the copper, the silkscreen half a millimetre from its pads, or the whole drill pattern offset as a block. Understand this before touching anything: Gerbv draws each file in the coordinate space that file declares, so when layers misalign,…
You double-click a file, or open it from Gerbv, and nothing useful happens: either the viewer stays empty, or a layer loads but the canvas looks blank. In almost every case the cause is not a broken board. It is a mismatch between what the file actually is and what Gerbv was asked to open,…
