Hi Brad,
I figured out the problem. I was passing some compilation flags
for my C compiler via CMAKE which was preventing the .bin from being
generated. Now I have a new problem but I am not sure if this is the
correct forum to discuss it as its related to application (mysqlclient).
After CMAKE is done, I do a make and below is the error.
*[ 0%] Building C object vio/CMakeFiles/vio.dir/vio.c.o
In file included from DIR/mysql-connector-c-6.0.2/vio/vio_priv.h:19,
from **DIR/mysql-connector-c-6.0.2/vio/vio.c:23:

There is a single declaration of the function rint as shown below
#ifndef HAVE_RINT
/**
All integers up to this number can be represented exactly as double
precision
values (DBL_MANT_DIG == 53 for IEEE 754 hardware).
*/
#define MAX_EXACT_INTEGER ((1LL << DBL_MANT_DIG) - 1)
/**
rint(3) implementation for platforms that do not have it.
Always rounds to the nearest integer with ties being rounded to the
nearest
even integer to mimic glibc's rint() behavior in the "round-to-nearest"
FPU mode. Hardware-specific optimizations are possible (frndint on x86).
Unlike this implementation, hardware will also honor the FPU rounding
mode.
*/
static inline double rint(double x) --> line 1583
{
double f, i;
f = modf(x, &i);
/*
All doubles with absolute values > MAX_EXACT_INTEGER are even anyway,
no need to check it.
*/
if (x > 0.0)
i += (double) ((f > 0.5) || (f == 0.5 &&
i <= (double) MAX_EXACT_INTEGER &&
(longlong) i % 2));
else
i -= (double) ((f < -0.5) || (f == -0.5 &&
i >= (double) -MAX_EXACT_INTEGER &&
(longlong) i % 2));
return i;
}
#endif /* HAVE_RINT */
With Regards,
Niranjan
