I reinstalled the blueZ (with --enable-mesh) , installed json-c from the git I can see the entry of the libjson-c unlike previously but it still gives the same error. Don't we have to link the libjson-c with the BlueZ while building by setting some Linker flags(LD) in the Makefile of the BlueZ.Is there any such option? How will I come to know that it has built successfully with the reference to the libjson-c. I believe we must have json-c pre-installed before building the BlueZ and Build setup of BlueZ must know where is the libjson-c. Rgards, Rp
