I'm trying to build a static version of libnfnetlink on an alpine build container. It uses the usual autogen->configure->make->make install route but for some reason it complains at the make stage about unknown types (u_int8_t, u_int16_t etc)
The output of each command:
bash-5.1# ./autogen.sh

I cannot figure out what the problem could be. The configure part correctly identifies that I have sys/types.h where the unknown types are defined but when I look in the src/.deps folder, I don't see it listed in the PLO file.
If i run the same steps in a centos 7 or 8 container, it works as expected. The only difference I can see in the configure stage between centos and alpine is that on centos it has these extra lines:
checking how to run the C preprocessor... gcc -E
checking for ANSI C header files... yes
I don't really know enough about autoconf/libtool to debug this or where I should be looking or if that is even the issue. From the information provided, does anything stand out as wrong or is there some other stage (not documented) that I need to follow?
So it seems I can answer my own question. I was using the latest release of libnfnetlink last week when I had the issue (1.0.1). There was a new release today (1.0.2) that had 9 years worth of fixes released, one of which was to not do the conversions I was having issues with e.g. __16 -> u_int16_t.
All builds fine now (and note to self, always check the history of the master branch)
