Cannot build on a fresh Ubuntu VM
CountBleck opened this issue · comments
I used a fresh Ubuntu VM, with nothing but GCC, make, perl, VirtualBox Guest Additions, and clang installed.
After having to rename ssize_t to size_t, and installing libreadline-dev, I ran into this:
I have little experience writing/compiling C, so I'm pretty much stuck.
What do I need to do to get it built?
UPDATE :: Apparently Linux libraries that relate to POSIX only have posix compliance if you define that they do. You still have to rename _CLOCK_MONOTONIC_RAW however to CLOCK_MONOTONIC_RAW
@Kylogias I am having the same problem and I changed it from _CLOCK_MONOTONIC_RAW to CLOCK_MONOTONIC_RAW and now its the same error here u go:
