Jconsole 抱怨“文件名错误”

Question

I am having trouble compiling and running J Programming Language

The Jconsole binary file (From J Language) throws an error when executed:

|file name error
|       0!:0 y

it compiled almost flawlessly but shows this warning

cc1: warning: function may return address of local variable [-Wreturn-local-addr]
In file included from ../../../../jsrc/j.h:1814,
                 from ../../../../jsrc/vi.c:6:

I had the same problem on Debian Linux. I ended up simply extracting the package

https://www.jsoftware.com/download/j903/install/j903_linux64.tar.gz

in /opt and added the line

alias jconsole="/opt/j903/bin/jconsole"

to ~/.bashrc .
