c - Cannot find header files -

-

i working on lwip tcp/ip stack on ti microcontroller board. explain, have 2 source folders "ipv4" , "ipv6". both have corresponding folders header files in "include" folder.

both have functions , structs same name. have included paths both. however, giving me errors in of functions in files in "ipv6" folder if cannot find folder header files , instead goes "ipv4" folder header files has same functions different number of arguments.

what doing wrong?

straight lwip wiki:

support ipv6 being added lwip. up version 1.4.x lwip can use either ipv4 or ipv6, not both. code dual stack operation in current development version (which can downloaded git). released version 1.5.0. consider lwip ipv6 quite stable.

so unless you're using unstable / dev version, can't use both. sounds attempting what's causing problems.
