I'm trying to build the software only mesa on cygwin but have a compile
error for a missing definition. Would any of you know where to look for
"M_E" from the following snip?
t_vp_build.c, build_fog()
case GL_EXP: emit_op1(p, VP_OPCODE_ABS, tmp, 0, input);
emit_op2(p, VP_OPCODE_MUL, tmp, 0, tmp, swizzle1(params,X));
emit_op2(p, VP_OPCODE_POW, fog, WRITEMASK_X,
register_const1f(p, M_E), negate(tmp));
^^^
M_E is the mathematical constant e, usually defined in <math.h>
from glibc :
# define M_E 2.7182818284590452354 /* e */
I'm adding
#ifndef M_E
#define M_E (2.7182818284590452354)
#endif
to mesa/src/main/imports.h now.
