HI , I have downloaded the new code , but I can't complie it , I can complie it succesful before. I use the CMAKE3.3.2, QT4.8.5, VS2010, but it appear the file is invalid and my system is win7 64. How to slove it ?

I'll need more info to help you ;)

But before that, have you updated your CMake project? (start Cmake and 'configure' the ptoject again).

Hi
I have started cmake and "configure" it , when I configure it , the error appare."CMake Error at CMakeLists.txt:21 (project):
No CMAKE_CXX_COMPILER could be found."

Then something has changed on your computer (probably the Visual Studio installation).

You should try to create a new CMake project (i.e. with a differnt build directory and select the compiler again, etc.).

HI
I have try it many times , but the have the same error.

Then maybe you'll have to reinstall Visual... As it's a CMake error, I can't do much...

HI
I have reinstalled the system, and complied it successfull, but I import the dxf file? why?

Do you mean you want to export DXF files?

Then you have to compile dxflib and 'link' it in CMake.

Hi
I want to import dxf files and can export at the same time.I have downloaded the dxflib code,and use the cmake to link it, and no error appear,but can not import dxf files also.

Well, I guessed you checked the OPTION_USE_DXF_LIB in CMake? Then compiled the INSTALL project again in Visual?

Otherwise can you test with the online version to see if you have the same issue?
