building project problem

Hi monkey:

I tried it again according to you but the result is same and failure, there was my steps:

1)nios2configtool --ptf=/.././../std_1c20.ptf --cpu=cpu and start the config diag.

2)choose the template "altera niosII board" and set "startup"=>"ROMRAM" ,SAVE the pjoject:" test" in the directory "h:/etest"

3)build->library

the building finished and no erro.

4)I copy all the files in the directory " /../../ecos_current/examples " to the " h:/etest"

5)change to the directory :cd h:/etest

6)in the directory , make INSTALL_DIR=/cygdrive/h/etest/test_install ,and the procedure is successful and a serials of *.o files were created.

7) "start=>program=>altera=>niosII IDE"

8)file=>new=>project

9) append "altera niosII " and choose "Advanced c/c++ Project" ,then click next

10)filled the niosII project 's name is: hello_ecos ,and unselect "use the default location" ,settintg it to "h:/etest" , which is the directory of the "ecos build project"

11)click next ,choose "maker builder" ,in the build command set "make INSTALL_DIR=/cygdrive/h/etest/test_install" and others did not change.

12)click "finish"

13)right click the niosii project "hello_ecos" and choose "build project" ,then the result is appear

make INSTALL_DIR=/cygdrive/h/etest/test_install all

make: *** No rule to make target `all'. Stop.
