About use scilab in Cygwin

[XiangJin]

Dear Sir.,

I am a beginner of Scilab, now I need your help to use Scilab in Cygwin.

I install the Scilab-4.1.2(linux) in Cygwin, and set the %scilib%\bin into system PATH,
when run scilab command in cygwin, as is:

scilab -nw -nwni -nogui -nb -f ext1c.sce

It appears the following error:
<<<<
make: scilab: Command not found
make: *** [bandfilters.h] Error 127
>>>>

I also try to run the following commands in order to run the scilab. but failed, the error appears again. 
chmod +x ./scilab
chmod +x ./scilink
chmod +x ./scilex

Please tell me how can I solve the problem, thank you.


Best Regards,
