Using the build script I get this.
Building libdxf.a failed
The reason why I am compiling from source is :
The elipse function does not produce proper code for use in Autocad or dxf to gcode and is just a mess.
Help function .. does not work also.
Using the build script I get this.

## Never built dxflib, but reading the error message, you are missing an include. On my same ubuntu system “man strcasecmp” tells me, its “#include \”. that should fix the other str… failures too. Try and put that statement into “src/dl\_writer\_ascii.h”.

The file dl\_writer\_ascii.h has the following entries
```plaintext
#ifndef DL_WRITER_ASCII_H
#define DL_WRITER_ASCII_H
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#include "dl_writer.h"
#include
#include
using std::string;
