Compilling MathGL with CMAKE on Windows 10 64 bits ERROR unistd.h

[Claudemir Mastelaro]

Hi everyone !

i'm trying to compile MathGL with CMAKE on my Windows 10 64 bits and i got an error because the file font.cpp includes unistd.h (unix include) without check the operational system

all external options are disabled and the error was:

C:\Users\cmast\Downloads\mathgl-2.4.1\src\font.cpp(23): fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory

NMAKE : fatal error U1077: 'C:\PROGRA~2\MICROS~1.0\VC\bin\amd64\cl.exe' : return code '0x2'

Stop.

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\amd64\nmake.exe"' : return code '0x2'

Stop.

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\amd64\nmake.exe"' : return code '0x2'

Stop.

i have changed the code to not use unistd instead 

#include <stdlib.h>

#include <io.h>

#include <getopt.h>

#include <process.h>

#include <direct.h>

and now another error on prim.cpp (1088)

C:\Users\cmast\Downloads\mathgl-2.4.1\src\prim.cpp(1189): error C2131: expression did not evaluate to a constant

Dear Claudemir!

I'm sorry for delay with answer -- I was too overwhelmed during last week.

About yours problem. It look as novel versions of MSVS don't define WIN32 (but should according the documentation). Contrary, they define _WIN32. So, the solution is manually pass definition WIN32, or use the latest version from SVN (I hope it was fixed a few days ago).

Kind regards,
Alexey Balakin
