Altera Monitor Program Error in Win8

Hi everybody

I'm trying to realize a simple project using Altera Monitor Program on a PC with Win8.

but when I'm going to compile the C source I receive the following error.

0 [main] bash 14212 find_fast_cwd: WARNING: Couldn't compute FAST_CWD pointer. Please report this problem to

the public mailing list cygwin@cygwin.com

Please note that the same project works perfectly on a older PC (with Win7 and maybe with a

older release of Altera Monitor Program)

Any suggestion ?

Thanks in advance

    Right, problem solved for me. Here is how:

    (1) extract the patch into some directory that is not the quartus one.

    (2) copy the contents of the "bin" folder (not the "bin64" folder) from the extracted files

    (3) paste this into <quartus directory>\quartus\bin64 replacing any files and folders.

    For some reason quartus 14 comes with a 32bit version of Cygwin installed in its bin64 directory (I discovered that when trying to use the 64bit Cygwin setup to upgrade it). So basically you have to use the 32bit files to patch it.

    Probably I've found tyhe solution:

    I've downloaded the cygwin new release (both the 32 and the 64 bit) and I've used them to substitute

    the cygwin software delivered with quartus.

    Moreover remember to include during the installation of cygwin the "perl" utility.

    I return on this old thread because I have exactly the same problem described by marsi but I can't solve it.

    OS: Win8.1

    Quartus 13.1

    Original cygwin distributed with Quartus generates a lot of "FAST_CWD pointer" warning messages

    Updating cygwin eliminates the "FAST_CWD pointer" warning messages, but I'm no more able to download the elf program to Nios.

    As marsi suggested, I updated both the 32bit and the 64bit parts and installed perl and afaik all other required packages.

    My current situation is:

    the project compiles fine, without errors

    nios2-configure-sof works perfectly

    nios2-download executes with no apparent error, but it actually does nothing

    If I launch the Run or Debug in Eclipse I get a generic error message

    I saved the old installation in \quartus\bin\cygwin_old directory.

    If I go back to the original cygwin installation by simply renaming it quartus\bin\cygwin I go back to the original situation: I can still download and debug nios project, but I get again FAST_CWD warnings

    Please help me. I'm really stuck on this point.

    Perfect!

    Now it works both for compilation and debugging.

    The problem was with updating directly from cygwin website, which fixes the compiling problem but somehow corrupts the download/debug features.

    Thank you!

    Windows 10, 32bit

    Quartus 13.0sp1

    worked for me (http://help.ece.ubc.ca/altera):

    To solve this issue, the Cygwin that is installed with Quartus II must be updated as follows:
