The XTrackCAD Wiki: DXFLib

For researching DXF import possibilities I started with DXFLib.

To get started:

download DXFLib from Ribbonsoft
create the following directories dxflib, dxflib\src, dxflib\build
unpack the downloaded archive into dxflib\src
DXFLib comes with support for the standard UNIX toolchain. You can use the following CMakeFiles:

For the base directory

# build the dxflib project

PROJECT(DXFLib)
CMAKE_MINIMUM_REQUIRED(VERSION 2.4)

IF(WIN32)
	SET(CMAKE_CXX_FLAGS_DEBUG "/D_DEBUG /MTd /Zi  /Ob0 /Od /RTC1" CACHE 
	    STRING "Flags used by the compiler during debug builds" FORCE)
	SET(CMAKE_CXX_FLAGS_MINSIZEREL "/MT /O1 /Ob1 /D NDEBUG" CACHE 
	    STRING "Flags used by the compiler during release minumum size builds" FORCE)
	SET(CMAKE_CXX_FLAGS_RELEASE "/MT /O2 /Ob2 /D NDEBUG" CACHE 
	    STRING "Flags used by the compiler during release builds" FORCE)
	SET(CMAKE_CXX_FLAGS_RELWITHDEBINFO "/MT /Zi /O2 /Ob1 /D NDEBUG" CACHE 
	    STRING "Flags used by the compiler during release with debug info builds" FORCE)

	ADD_DEFINITIONS(-D_CRT_SECURE_NO_WARNINGS)
ENDIF(WIN32)

# build the library
ADD_SUBDIRECTORY(src)

# build the test program
ADD_SUBDIRECTORY(test)

For the src directory

# build dxflib

FILE(GLOB HEADERS *.h)

SET(SRCS 
	dl_dxf.cpp 
	dl_writer_ascii.cpp 
	)

ADD_LIBRARY(dxflib ${HEADERS} ${SRCS} )
SET_TARGET_PROPERTIES(dxflib PROPERTIES LINKER_LANGUAGE CXX)

and for the test directory

# build the test program

ADD_EXECUTABLE(main main.cpp test_creationclass.cpp)

INCLUDE_DIRECTORIES( ../src )
ADD_DEPENDENCIES( main dxflib )
	
TARGET_LINK_LIBRARIES(main dxflib)

Configure in CCMake and build
