I'm getting this error when I run make
Makefile:62: *** missing separator. Stop.
This is on of my favorites. It's often because you have four spaces instead of a tab prefixing the line.
How to turn on or off asserts in C++
$ cat x.c
#include <assert.h>
int main(int a, char** b) {
assert(0);
return 0;
}
$ gcc x.c -DNDEBUG
$ ./a.out
$ gcc x.c
$ ./a.out
Assertion failed: 0, file x.c, line 4
Abort (core dumped)
NB you will have compiled away all the asserts by defining NDEBUG!
