"Can't locate sh_launch.pm" ... build error (windows)

Hi all,

We have the following issue building our FPGA / NIOS images (the following was run from the NIOSIIEDS shell via make):

[...]

Can't locate sh_launch.pm in @INC (@INC contains: /cygdrive/c/altera/quartus10/nios2eds/bin c:/altera/quartus10/bin/cygwin/lib .) at line 2.

[...]

A check with

ls /cygdrive/c/altera/quartus10/nios2eds/bin/sh_*

clearly shows that the file is there since the result of the command is the following output:

/cygdrive/c/altera/quartus10/nios2eds/bin/sh_jar.sh*

/cygdrive/c/altera/quartus10/nios2eds/bin/sh_launch.pm

/cygdrive/c/altera/quartus10/nios2eds/bin/sh_pl.sh*

I looked at some similar issues here in the forum but the ones I tried did not lead to a positive result.

What could be the reason for the error? Why can't it find a file that is clearly in one of the paths it is looking for?

Could chmod'ing the permissions for sh_launch.pm be worth a try? (currently at "-rw-r--r--")

Thanks a lot for taking the time to read this and any adivise you can provide.
