Failure when building "video_enc_con"

[isn-removed200717]

"video_enc_con" is one of the Media Processing Samples. I met with a failure when I built it. The error message is:

LIBCMT.lib(crt0dat.obj) : error LNK2005: _exit already defined in MSVCRT.lib(MSVCR71.dll)

I have downloaded and installed the latest IPP 5.0 andI'm using VC.NET 7.1. The DirectX SDK 9.0 also installed. Please help me tackle this problem. Thanks!

Hi,

do you use build scripts which provided with this sample or you created your own MSVC project instead?

Yes, I am using "build32.bat" under the "media" directory. There will be no error if running withthe "cl" parameter.

Before that I also created a MSVC.net project in another separate sample root directory. Thereare also errors while linking: some ipp fuctions can be resolved but some can not -- very strange.

Hi,

if I understood you correctly, you have no problems with sample and build script which comes with sample. Is that correct?

But you have errors at linkage stage with MSVC project which was created by your own. Right?

Errors you got usually caused when you link modules which use different CRT, for example static single-thread run-time libraries in one module and multithreaded DLL run-time libraries in another module. Could you please check project settings to verify you use the same run-time libs?

Vladimir

Thank you for your reply. I have successfully build the "video_enc_con" using the Microsoft VC.net 7.1 solution. Theproblems in the former VC project are:

(1)The target is a console and I set it to window application

(2)An additional compiling option "/D_WIN32_WINNT=0x0501" should be added (for XP)in the "vm" project, without which TryEnterCriticalSection function can not be resolved when linking vm_mutex_win32

(3)I forget to add ippvc.lib :-)

Oh, that's great:)

BTW, have you been satisfied with functionality and/or performance of encoders?

Vladimir
