FreeBSD Makefile problem with json.

[lagagne]

I just built host-sflow from sources for FreeBSD 11.0

The "make" command brings these errors for the json Makefile: Lines 24 and 27: Missing dependency operator. Line 30: Need an operator.

I tried running "gmake" but after leaving the json directory successfully (Nothing to be done for 'all') it doesn't understand the FreeBSD Makefile.

I commented out the "cd src/json; $(MAKE)" from the main Makefile and ran "make" again and successfully completed the installation.

Thanks. It seems like we should allow each platform to compile cJSON in it's own way.

Hello,

I have the same problem installing host-sflow v2.0.51-26 on FreeBSD 13.2, and here is the error messages:

When using make:

Stop.

Although I can disable the json as mentioned by @lagagne, I hope this issue can be fixed.
Thank you.
