Re: [Bug-apl] Gnu APL Quad-Quote read coming from souce file and not the terminal

[Frederick H. Pitts]

Hello Juergen,

        I cloned svn 472, configured and tried to build.  I find that if
I configure with CORE_COUNT_WANTED=argv, the following compiler error
results:

Parallel.cc: In static member function 'static void
Parallel::init_CPUs(bool)':
Parallel.cc:333:7: 'uprefs' was not declared in this scope
        uprefs.requested_cc;     // parallel, as per --cc option

A similar but differ error occurs if I use CORE_COUNT_WANTED=syl.

        If I configure without specifying CORE_COUNT_WANTED, the build
completes OK.  However I'm still having the problem of the ⍞ reference
not reading from the terminal.

        Something as simple as:

#!/usr/local/bin/apl --script --
⍝ ------------------------------
∇hello; X
 ⍞ ← 'What is your name?  '
 X ← ⍞
 ⎕ ← 'Hello ', ( X ≠ ' ' ) / X
∇

hello

)OFF
⍝ ------------------------------

demonstrates the issue.  If the above is executed as a shell script with

        ./hello.apl

or the apl invocation

        apl -f hello.apl

the ⍞ reference input is not coming from the terminal.

Regards,

Fred
