panotza / gosmc Goto Github PK

Hi @panotza,

gosmc is licenced under the MIT licence, but it includes GPL-licenced files smc.h and smc.c that don't include any linking exception. Anything building against gosmc statically links this code as it's imported/called with cgo, so to my knowledge (IANAL), this library (and its downstream users) may have to be GPL-licenced (this is debated, but gopsutil was also using a derivative of these files and had to remove them because of their licence in shirou/gopsutil#518). You may have to relicence to GPLv2 to be on the safe side.

Regards

When installing with go install github.com/panotza/gosmc

I get the following message:

smc.c:73:5: warning: 'IOMasterPort' is deprecated: first deprecated in macOS 12.0 [-Wdeprecated-declarations]
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/IOKit.framework/Headers/IOKitLib.h:143:1: note: 'IOMasterPort' has been explicitly marked deprecated here

It would be nice if you included a few examples of how to use this package (this is common for Go packages), say for how to set fan speeds.

gosmc is MIT licensed, but it includes smc.c and smc.h which are both GPL. Any software embedding GPL code must be licensed under the GPL; it can not (legally) be relicensed under MIT.

Can I use GPL-licensed code in my MIT-licensed project?

No. The project as a whole must conform to the terms of the GPL license and must be distributed under the terms of that license. Therefore such a project as a whole must be distributed as GPL, but can still contain MIT-licensed software.
