Coova-Chilli Compile Error

[tiago.duque]

Hi everyone, I got the following error when compiling coova-chilli on Openwrt/Lede 17.04.1:

It seems like it couldn't find sysinfo struct, so the memory set for the variable 'the_info' can't be created. Does anyone have an idea to solve this situation?

Thanks.

You might consider to file a bug, as I suspect, your issue is target-specific. I have chiilis built for ramips and ar71xx without problems.

[tiago.duque]

It was build for a x86_64, with glibc.

Coova-Chilli was recently updated to 1.4 in the packages repo. This may help. Your issue is glibc specific I think.

[tiago.duque]

It's because "struct sysinfo" ins't declared at all, so the compiler can't determine the size of this struct. The lib <sys/sysinfo.h> must be included into chilli.c to work. Here is some patch that I made to solve this problem if someone still having this issue.

thanks, but such conditional include does not help.
I do int unconditionally,
only
#include <sys/sysinfo.h>

p.s. it's for tag v18.06.5, coova-chilli-1.3.0+20141128
