Hi,
I've just spent a couple of days working to get gnu-apl up and running under OS X Catalina. Good progress has been made, but I'm unsure if I have a stable and fully functioning copy of the interpreter.
During this exercise, I encountered four experiences that may indicate bugs. They are:
- Build Issue?: Newly saved workspaces rejected as ancient by interpreter
- Quirk?: Sqlite3 connection error message comes and goes
- Mystery?: Quad-Plot usage
- Bug?: ⎕SI for non function execution errors?
I'm unfamiliar with the gnu packaging tools and completely overwhelmed by this enormous code base. Thus, I apologize in advance for any limitations or mistakes in this report.
Regards,
John Helm
1) Build Issue: Newly saved workspaces warned as ancient by interpreter
The "standard" compile and install sequence using the apl-1.8.tar.gz tarball does not compile correctly on OS X Catalina.
The problem is configure runs svn commands to write a file ./src/buildtag.hh and these commands fail because the tarball is not an SVN repo. The resulting binary compiles without a build number. The net result is workspaces are saved with a null build number, and )LOADing these files fails with the following message:
WARNING: this workspace was )SAVEd with a VERY old SVN version of GNU APL.
Expect problems, in particular when the )SI was not clear.
In case of problems, please try )COPY instead of )LOAD.
DOMAIN ERROR+
immediate_execution() caught APL error 0x50004 (DOMAIN ERROR)
Here are some details from the compilations:

To follow is a screen log in which apl was loaded four times. Every other load emits an error messages as follows:
1st load: No connection error message
2st load: ::connect() to supposedly existing APserver failed: Invalid argument
Svar_DB not connected in Svar_DB::is_registered_id()
3rd load: No connection error message
4st load: ::connect() to supposedly existing APserver failed: Invalid argument

3) Mystery Quad-Plot usage
All attempts to invoke ⎕PLOT result in a SYNTAX ERROR.
⎕plot ''
SYNTAX ERROR
⎕PLOT
^
⎕XYZ
VALUE ERROR
⎕X YZ
^
I note that this behavior is expected for ⎕RE if libpcre2 is absent when gnu-apl is compiled...
SYNTAX ERROR
⎕RE
^
'abc' ⎕RE 'aaaaabcccc'
SYNTAX ERROR+
'abc' ⎕RE 'aaaaabcccc'
Does this behavior indicate some prerequisites are missing for ⎕PLOT to work?
================================================================
4) Bug?: ⎕SI for non function execution errors?
4.1) It appears many (all?) errors cause push a event State Indicator. Other apl interpreters I've used do not push events such as value errors or domain errors on the State Indicator. Is this intended behavior?
4.2) The GNU APL info page indicates ⎕si's arguments include 5 and 6, but these return errors on my version. Is this a documentation error?
