Ubuntu LTS 10.04 Compile Issue

dxflib dxflib Troubleshooting and Problems
1

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 <strings.h>”. 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

#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 <fstream>
#include <string>
using std::string;
