[etherlab-dev] Cannot compile for kernel 4.14

[Joye Laurent]

Hello,

I'm using the code from etherlabmaster (default branch) + your own
patches (Patchset 20171108 based on default branch 33b922ec1871).

I'm trying to compile a kernel 4.14 with rtmutex enabled at configure
time.
The compilation fails because an include directive is missing. If I add,
in the file master/locks.h, the line "include <linux/rtmutex>" right
after the line "#ifdef EC_USE_RTMUTEX", it works.

Thanks to consider this note

My apologies for the late reply. I've tried this myself (without the extra #include) and it compiles ok.

Are you using an -rt patched kernel? There is an assumption that if you want rtmutexes you should be using an -rt patched kernel as well, as otherwise they would provide less benefit.

Many thanks,
I don't use a real time kernel. So I disabled the rtmutex. All is now
fine
