ecos on niosii

hello monkeyboy:

when QII4.1sp2 been installing, the cygwin was installed too . Can you tell me if this version is the correct cygwin using by QII4.1 and ecos.

u told me that I can set the path of the "user tools " using the default (path=d:\nios2\bin\nios2-gnutools\H-i686-pc-cygwin\bin ), I tried it ,but when i applied it ,then a dialog box was appeared which content is that "d:\nios2\bin\nios2-gnutools\H-i686-pc-cygwin\bin does not appear to contain the user tools ---use this folder anyway " when I choose "yes" ,the builded result is below:

"make[1]: Leaving directory `/cygdrive/d/nios2/components/ecos/ecos-work/a_build/hal/nios2/arch/v2_0'

/cygdrive/d/nios2/components/ecos/ecos-work/a_install/gtf-launch: not found

make -r -C hal/nios2/arch/v2_0 /cygdrive/d/nios2/components/ecos/ecos-work/a_install/include/cyg/hal/system.h

make[1]: ***make[1]: *** [/cygdrive/d/nios2/components/ecos/ecos-work/a_install/include/cyg/hal/system.h] Error 255make[1]: `/cygdrive/d/nios2/components/ecos/ecos-work/a_install/gtf-launch' is up to date.

make: *** [build] Error 2

and after changing the path ,the file "gtf-launch" was found ,but the error seemed to be changed .

On our PC ,the "cygwin " following the QII4.1sp2 is the only "cygwin" , and the version of the niosII is "Version: 1.0, Build: 316e + sp1" , what's wrong and is the version of the "cygwin" is right? If the path of QII4.1sp2 is that "path= d:/altera" and the path of NIOSII is "path=d:/nios" ,the ecos is installed in "path=d:/nios2/compinent / " .when I configurate the project "d:/nios2/examples/ verilog/niosII_cyclone_1c20/standard/" where is the right path of the configuration .

thanks !
