libmodbus: update to 3.1.11

2025-12-28T10:48:16Z

fixes float endianness issues in 3.1.8. I use a small, custom application to convert data from my electricity meter into Modbus format for my inverter and wallbox. I developed this program against an earlier version of libmodbus on x86, and it ran flawlessly on my ath79 router (big endian). After migrating to a Mediatek router (little endian), the program only outputted huge, meaningless values. However, it ran perfectly fine on my x86 system (little endian), which is running Fedora with libmodbus v3.1.11. I then found several bug reports and the changelogs for libmodbus 3.1.11 that described and resolved my problem. So update openwrt to 3.1.11. Signed-off-by: Stefan Hellermann

libmodbus: update to 3.1.6

2019-09-16T21:19:15Z

Also fix the license information: in older versions the test programs were GPL 3 licensed, but meanwhile it changed to BSD license. But since this package only packages the library itself, we can safely focus only on the LGPL here which covers the library itself. While at, fix a minor nitpick during library symlink installation.

treewide: Change .GPL.+ licenses to SPDX compatible identifier

2019-09-10T05:45:15Z

The CONTRIBUTING.md requests an (or multiple) SPDX identifier for GPL licenses. But a lot of packages did use a different, non-SPDX style with a "+" at the end instead of "-or-later". Signed-off-by: Sven Eckelmann
