Hi
I never tried spdlog on OSX. I hope it works!

Try to replace line 145 with lines 161-163 (i im just guessing):

  result = strerror_r(error_code, buffer, buffer_size); 
   if (result == -1)    
       result = errno;  // glibc versions before 2.13 return result in errno

If this doesn't help i think you can just comment out this function. Spdlog doesn't use it..

Newer version of C++ Format which is where format.cc (and the error =)) coming from has better detection of strerror_r here.
