‘UINT32_MAX’ undeclared problem in Linux

Problems: UINT32_MAX’ undeclared problem in Linux

Why I post this issue?

I use make to build the program, and found this problem:

$ make
cc -o kilo kilo.c -Wall -W -pedantic -std=c99
kilo.c: In function ‘editorUpdateRow’:
kilo.c:567:21: error: ‘UINT32_MAX’ undeclared (first use in this function); did you mean ‘__UINT32_MAX__’?
     if (allocsize > UINT32_MAX) {
                     ^~~~~~~~~~
                     __UINT32_MAX__
kilo.c:567:21: note: each undeclared identifier is reported only once for each function it appears in
Makefile:4: recipe for target 'kilo' failed
make: *** [kilo] Error 1

My environment:

$ uname -a
Linux beaglebone 4.9.78-ti-r94 #1 SMP PREEMPT Fri Jan 26 21:26:24 UTC 2018 armv7l GNU/Linux

How I fix it ?

Just include <stdint.h> and the program compiled correctly with no errors.

Test kilo on MacOS

I found no erorr when compiling.
And my environment on MacOS is:

$ uname -a
Darwin unknowntpo.local 19.4.0 Darwin Kernel Version 19.4.0: Wed Mar  4 22:28:40 PST 2020; root:xnu-6153.101.6~15/RELEASE_X86_64 x86_64
