Is Cygwin needed to build the XDC based projects in CCS for evmDm648

Hello

 Can anybody please tell me weather i need to install cygwin for running XDC based code for evmDM648.

As i am trying to build the code with CCS do i still need the cygwin? I am getting an error about not being able to allocate heap for cygwin while trying to build the project.

How can i find the cause of this error?

 

Somebody please guide me about this. 

  • I do not believe you need to install Cygwin for building an XDC based project, I had built XDC projects for other platforms successfully, namely the DM6437 demo, before I had installed Cygwin. I have not done as much work with the DM648 DVSDK but taking a quick look at the getting started guide and release notes I see no mention of Cygwin.

    Could you post a copy of your build output with the error here? With the error message we can probably point you in the right direction to fixing it.

    EDIT: I see your prior post has the build output already.

  • I never had to specifically install Cygwin in order to build any of the example projects in the DM648 DVSDK. I do not think I had installed it manually in the past either. I will look into the error you posted in your other thread to see if I can find any clues.

  • Thank you for your response.

    I have solved the problem by Hit or miss method. While looking for possible cause for that error i found cygwin1.dll at xdc directory in bin folder. while searching for same type of error on net i found that

    1) having multiple cygwin1.dll in system can cause problems

    2) Most people recommended either reinstalling cygwin or try using updated dll.

    First step didnt help me solve the problem ( I removed the same dll found in bios directory ) but it works fine when i replaced cygwin1.dll with a newer version found on net.

    I think there is some compatibility issue with this dll . Can anybody give the exact explanation??

    Thanks alot!!

  • I am asking around to see if I can find out why this happened.
