configure kernel fails

when i want to configure my kernel in the drop down menu, the window opens shortly and closes a second later. normally opens the blue configuration window, but here only the bash window for just a moment. i tried it with different kernels, it's always the same.

knows someone this problem????

thx

    That's a known problem... could've sworn there was a thread about this earlier that I could point you to. Anyhoo...

    The only tested and true method of debugging this issue is:

    (1) modify the configure.bat file in your kernel project within the Nios II IDE

    (2) remove the @start from the beginning of the line in the batch file

    (3) open up a regular command prompt (not a Nios II SDK Shell)

    (3a) run cd ...altera\kits\nios2\bin\eclipse\workspace\<kernel project>

    (3b) run configure.bat

    You should now be able to view the error messages.

    Common issues:

    gcc or nios2-elf-gcc not found...

    ... you may need to run SOPC Builder at least once in order for your Quartus II/SOPC Builder installation to be complete. After running SOPC Builder, try configuring the kernel again

    crt0.o not found...

    ... this is trickier, you need to double check that a crt0.o file exists within the ...quartus/bin/cygwin/usr/lib directory. This is the one that the kernel configuration is trying to link against. If it&#39;s there then something is different about your mount points than what we expect it to be. We typically unmount the current /usr/lib if it&#39;s mounted, so you may try that from the Nios II SDK Shell before attempting to configure your kernel again.

    any other error messages, let me know...

    I&#39;ve had a similar problem on a system on which a standalone copy of Cygwin was installed. I&#39;m guessing that the uClinux installer found Cygwin and not Quartus&#39; Cygwin, which led to some kind of problem finding gcc. I couldn&#39;t get Cygwin and Quartus Cygwin to coexist, so I uninstalled Cygwin, reinstalled uClinux, and it all worked.

    If the installer asks you for the location of Cygwin, make sure you point it to Quartus II 4.0&#39;s Cygwin.
