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:
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:
