ecos on niosii

Hello rugbybloke:

when I secondly used configation tools to builde the project ,I found the problem last posted appeared ,it was said that the promble was not fixed yet. Additional , when I change the path of the user tools (which is listed :TOOLS->Paths->user tool) ,in default ,the path=d:\nios2\bin\nios2-gnutools\H-i686-pc-cygwin\bin ,and the result is that

"make: Entering directory `/cygdrive/d/nios2/components/ecos/ecos-work/ai_build'

make -r -C hal/nios2/arch/v2_0 headers

make[1]: Entering directory `/cygdrive/d/nios2/components/ecos/ecos-work/ai_build/hal/nios2/arch/v2_0'

ÃüÁîÓï·¨²»ÕýÈ·¡£(syntax of the command is incorrectness)

make: *** [headers] Error 2

make --directory "/cygdrive/d/nios2/components/ecos/ecos-work/ai_build"

"

but when i changed the path of user tools:path=d:\altera\quartus41\bin\cygwin\bin

the result is below:

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

make[1]: *** [/cygdrive/d/nios2/components/ecos/ecos-work/ai_install/include/cyg/hal/system.h] Error 127

make: *** [build] Error 2"

as same as before. what is wrong with me ,and which path of the user tools is right? Meanwhile ,whether I should install another Cygwin to the system? and how can i get the detial information of the error ,such as error 127,1 etc.

I am crazy , I don't know how to reslove it ,all the configation are executed according to

the ecos 2.0 for niosII docs.

help me ,my God!
