Compilation Error when trying mir-optim BetterC

[vladislavp]

Hello,
I am trying to create a 'boiler plate' project
that's essentially uses only betterC libraries
(and itself is betterC)

for my needs I would like to use mir-optim
(this is a linear optimization betterC lib)

However, I cannot seem to get passed compilation errors
when including mir-optim library.

I do not have any problem including mir-cpuid library.
So I am somewhat confused what I might be doing wrong.

Thank you in advance for any help.
