I have a copy of Stretch installed, which comes with dhcpcd 6.11.5. I would like to modify dhcpcd,and I'm having trouble.
I downloaded the current dhcpcd 7.99 from github. It compiles OK but does not run correctly, and it's clearly very different from the one on the system.
I downloaded the 6.11.1-DNA version from github, but it won't compile. It seems to want the header file <curl/curl.h>, which is not in the package, and even though curl is installed on my PI, there is no such header file in /usr/include.
The Raspbian branch on github doesn't seem to include utilities like dhcpcd.
Where can I find, or how can I configure, dhcpcd source code to compile and run correctly on my pi?
