Missing LIB files. BCI2000 + Visual Studio

[skvpe]

Hello,

I am a beginner in BCI2000 environment and I request your help in the following issue.

I am running BCI2000 in MS Visual Studio 2010 and I followed the instructions given in wiki. I got BCI2000.sln as mentioned there and was able to build all and generate exe files for all projects. Next I want to run BCI2000 with CyUSB USB controller and create a signal source which will acquire data from CyUSB device. So I added corresponding header and cpp files in 'SignalGenerator' project.

After building, I got linker error saying it cannot find .lib files in folders BCI2000src\build\cmake\frameworks\...

I found out 5cmake files (LibTiny,Core,SigProcModule,SigSrcModule,AppModule) whose *.lib files don't exist. All the projects have this 'frameworks\..\*.lib' files mentioned in Properities->Linker->Include->Additional Dependencies in VC++

Then I tried to CMake LibTiny using the GUI->
Source code = ../frameworks/LibTiny.
Generated using = Visual Studio 2010 by default native compilers

Error: Project files may be invalid.

CMake Error at test/CMakeLists.txt:7 (BCI2000_ADD_LIBRARY_TEST):Unknown CMake command "BCI2000_ADD_LIBRARY_TEST".

CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as cmake_minimum_required(VERSION 3.1) should be added at the top of the file. The version specified may be lower if you wish to support older CMake versions for this project. For more information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.
Configuring incomplete, errors occurred!

I tried to remove them from linker dependencies but got lot of 'undefined' errors after building the project.

Can anyone please explain how to generate these lib files?

I'm not going to address your issues specifically, rather I think you should revert your src tree back to its original state and take a different approach.

If you selected to build certain tools, then you should have a NewBCI2000Module.exe in your build directory.
Follow these instructions for making a new source module.

This should place a new folder in your BCI2000/src/custom folder and it will also update the CMakeLists.txt file in that folder.

Go into your custom module's folder and edit its CMakeLists.txt. Beyond the basic SRC_PROJECT and HDR_PROJECT, you'll also have to specify your hardware's include directories and library directories. To know how to do this, take a look at some of the other source modules as examples.

Then MAKE again.
Then open the VS sln and find your new module and code away.

I've included my CMakeLists.txt for a libusb device. There are probably some inefficiencies, but it works.

Hello,

Thanks a lot for your reply. I did try as you recommended. But build fails due to those missing lib files. I will try installing latest version again..

Thanks for libusb code!

Hi bouley,

The problem was cmake put these lib files in src->build->CmakeFiles->Frameworks folder whereas the compiler was accessing src->build->cmake->frameworks folder. So I had to copy files to this folder to remove the error.

Currently when I run this code as signal source, I get another error after doing 'Set Config' in BCI2000.

exe files-> Operator-><above code>->Dummysignalprocessing->Dummyapplication

Error->DataIOFilter::Initialize: CyAPIADC::Initialize: Parameter "SamplingRate" was accessed during initialization or processing, but not checked for consistency during preflight phase.

Files->CyAPIADC.cpp and CyAPI.cpp (driver USB file). Headers->CyUSB headers and CyAPI.h

Any idea regarding this error?

Try adding this line in Preflight:

Code: Select all

mSamplingRate = Parameter( "SamplingRate" );

[skvpe]

That solved the issue. I just had to remove 'const' from declaration of preflight in few header files to make that work.

Thanks!
