Hi All,=0D=0A
Further to the below mail from Peter Stephenson, this=0D=0Awould give a b= road overview of the changes to Zsh project during its migration=0D=0Aonto = Symbian OS=2E=0D=0A
=0D=0A
Let me know= how can we move further on this activity=2E=0D=0A
=0D=0A

Symbian OS supports Zsh
=0D=0A
=0D=0A
   1= =2E        Overview:=0D=0A
The Open source Zsh was migrated onto Symbian OS using=0D=0APIPS = (PIPS is POSIX on Symbian OS) libraries, the Standard set of POSIX=0D=0Alib= raries on Symbian=2E=0D=0A
=0D=0A
None= of the Zsh project defects have been fixed during=0D=0Athis activity and a= ll the changes are to support Zsh on Symbian OS=2E=0D=0A
=0D= =0A
 2=2E        Limitati= ons:=0D=0A
This section elaborates th= e features that were not=0D=0Asupported due to the limitations in PIPS/Symb= ian=2E=0D=0A
a=2E Signal related featu= res are not supported -=0D=0A
PIPS cu= rrently don’t support Signals, because of=0D=0Awhich features like st= opping, terminating a process are not supported=2E=0D=0ASignals are being i= mplemented and this can be supported soon=2E=0D=0A

The build and the project specifi= cation files for=0D=0ASymbian reflect the =2EMakefile of Zsh project=2E The= tools of Symbian will=0D=0Ause these specifications to generate the binary= =2E=0D=0A
=0D=0A
      = b=2E        Source=0D=0Achanges=0D=0A
Most of the changes during the migration have been=0D=0Abl= ocked under __SYMBIAN32__ which is defined by the tools=2E=0D= =0A
=0D=0A
As Symbian doesn’t support two ph= ase construction=0D=0Aof a process, popen3() an API which creates a process= with the image and=0D=0Agets three file descriptors corresponding to the s= tdio of the client process=0D=0Ais used instead of fork() and exec ()=2E &n= bsp;Most of the changes done to=0D=0AZsh project are specific to the usage = of popen3 ()=2E=0D=0A

Hi,
=0D=0A
=0D=0AThanks for the note= =2E=2E=2E we'd certainly be interested in integrating your
=0D=0Achanges= back to zsh=2E  This would have to be the latest development=0D=0Aver= sion
=0D=0A(4=2E3) since there isn't any active development of older bra= nches=2E
=0D=0A
=0D=0AAs you no doubt know, most of the discussion ab= out details goes on on the
=0D=0Azsh-workers mailing list=2E  We'd = be happy to look at patches to allow
=0D=0Acompilation on Symbian=2E &nb= sp;Putting appropriate #ifdef's in the code=0D=0Ais
=0D=0Aprobably the e= asy bit; setting up the configuration in the first place=0D=0Ais
=0D=0Ap= erhaps more difficult=2E  Are you using a cross-compiler?  This= =0D=0Aprobably
=0D=0Amakes things difficult, since zsh has to probe vari= ous bits of run-time
=0D=0Abehaviour when configure is run=2E  We w= ould probably need to look at=0D=0Aother
=0D=0Aways of providing the nec= essary information=2E  Alternatively, I suppose=0D=0Awe
=0D=0Amight= be able to supply a library of pre-built configuration headers for
=0D= =0Aspecial cases like this=2E
=0D=0A
=0D=0AAnyway, if you let the mai= ling list know the sort of changes you have we
=0D=0Acan start to think = about the best way of integrating them=2E
