In Debian Linux + ghc-7.4.1,

I remove  *.agdai, *.hs, *.hi, *.o  files of my application
(and do not touch files made from Standard library)
and command

    agda -c -v 2 $agdaLibOpt AlgTest.agda  > & log

This prints to the file  ./log  (I format this output a bit):

Compilation error:

I see this in  ./log.   Is this  stdout ?

1) What precisely is this command for running GHC ?

Is it
  cd  <where AlgTest.agda resides>
  remove  ./AlgTest,  *.hi, *.o  files  of the application
  ghc -O -o /home/mechvel/doconA/0.01/source/demoTest/AlgTest -Werror
    -i/home/mechvel/doconA/0.01/source/demoTest -main-is MAlonzo.Code.AlgTest
    /home/mechvel/doconA/0.01/source/demoTest/MAlonzo/Code/AlgTest.hs
    --make -fwarn-incomplete-patterns -fno-warn-overlapping-patterns
?

2) How to see  stderr ?

Thanks,
