Hi Folks I added some code (modified) tcpdump to write the pcapng file. while configuring/compiling the source code I get this error This is a cross compilation for ARM platform
configure: error: *flex is insufficient to compile libpcap.* libpcap requires Flex 2.5.31 or later, or a compatible version of lex. # flex -V flex 2.5.37 Same error is true for bison/m4. (I am not sure what is that tool for) Any help in this regard?
