Root cause: The *_finite calls have been removed on lib math (see https://reviews.llvm.org/D74712)

Temp fix for those who want to build it for those games until its fixed propoerly:

create a file mymath.c

#include <math.h>

double __pow_finite(double x, double y);
float __atan2f_finite(float y, float x);
float __atan2_finite(float y, float x);
float __log_finite(float num);
float __acosf_finite(float num);
float __acos_finite(float num);
float __asin_finite(float num);

double __pow_finite(double x, double y)
{
   return pow(x, y);
}

float __atan2f_finite(float y, float x)
{
   return atan2f(y, x);
}

float __atan2_finite(float y, float x)
{
   return atan2(y, x);
}

float __log_finite(float num)
{
   return log(num);
}

float __acosf_finite(float num)
{
   return acosf(num);
}

float __acos_finite(float num)
{
   return acos(num);
}

float __asin_finite(float num)
{
   return asin(num);
}

Compile it and create the lib:

gcc -m32 -c mymath.c
ar rcs libmymath.a mymath.o

Link your metamod build with this library

Thanks. It seems this affects any game/mod that's compiled against libm from the Scout version of the Steam Runtime SDK

This is supposed to be fixed in the build by linking in https://github.com/alliedmodders/amtl/blob/master/compat/stdcxx.cpp

[dvander]

Oh, we never actually do that. That'd be why.
