Cannot build on a fresh Ubuntu VM

[CountBleck]

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?

See #10

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: ubuntu@default:/jdh-8$ make mkdir -p bin clang -o emu/kb.o -c emu/kb.c -std=c11 -O0 -g -Wall -Wextra -Wpedantic -Wstrict-aliasing -Wno-pointer-arith -Wno-unused-parameter -Wno-gnu-zero-variadic-macro-arguments clang -o emu/emu.o -c emu/emu.c -std=c11 -O0 -g -Wall -Wextra -Wpedantic -Wstrict-aliasing -Wno-pointer-arith -Wno-unused-parameter -Wno-gnu-zero-variadic-macro-arguments emu/emu.c:21:34: warning: implicit declaration of function 'fileno' is invalid in C99 [-Wimplicit-function-declaration] struct pollfd pfds = { .fd = fileno(stdin), .events = POLLIN }; ^ emu/emu.c:35:14: warning: implicit declaration of function 'strcasecmp' is invalid in C99 [-Wimplicit-function-declaration] if (!strcasecmp(speed, "realtime")) { ^ emu/emu.c:99:5: warning: implicit declaration of function 'strlcpy' is invalid in C99 [-Wimplicit-function-declaration] strlcpy(str, text, sizeof(str)); ^ emu/emu.c:170:19: warning: implicit declaration of function 'fmemopen' is invalid in C99 [-Wimplicit-function-declaration] FILE f = fmemopen((void ) out, n, "wb"); ^ emu/emu.c:170:15: warning: incompatible integer to pointer conversion initializing 'FILE ' (aka 'struct _IO_FILE ') with an expression of type 'int' [-Wint-conversion] FILE f = fmemopen((void ) out, n, "wb"); ^ ~~~~~~~ 5 warnings generated. clang -o emu/libemu.o -c emu/libemu.c -std=c11 -O0 -g -Wall -Wextra -Wpedantic -Wstrict-aliasing -Wno-pointer-arith -Wno-unused-parameter -Wno-gnu-zero-variadic-macro-arguments emu/libemu.c:45:17: warning: implicit declaration of function 'clock_gettime' is invalid in C99 [-Wimplicit-function-declaration] u64 start = NOW(), ^ emu/libemu.c:15:17: note: expanded from macro 'NOW' assert(!clock_gettime(MONO_CLOCK, &ts)); \ ^ emu/libemu.c:45:17: error: use of undeclared identifier 'CLOCK_MONOTONIC_RAW' emu/libemu.c:15:31: note: expanded from macro 'NOW' assert(!clock_gettime(MONO_CLOCK, &ts)); \ ^ emu/libemu.c:10:21: note: expanded from macro 'MONO_CLOCK'

This is the same issue as #21, moving discussion there.
