LLONG_MAX

All,

Could somebody explain me why this does not compile?
----lim.cpp-------
#include
void main()
{
long long i = LLONG_MAX;
}

getting following error:
lim.cpp: In function `int main(…)’:
lim.cpp:4: integer constant out of range
lim.cpp:4: warning: decimal integer constant is so large that it is unsigned
cc: /usr/lib/gcc-lib/ntox86/2.95.3/cc1plus error 33


Running QNX 6.2 NC.


Thanks,

This is fixed in 6.2.1. It’s a problem with /usr/include/limits.h that you
can fix yourself. Basically, the LL suffix is in the wrong section of the
#ifdef. See the diff below.

cheers,

Kris

Most excellent ! Any chance of this appearing on the new 3rd party CD ?

I cant answer your question, I am relatively new in QNX and dont know how
things are going.
