John,

I did install the readline-dev package (libreadline5-dev), which got past
the readline dependencies. Is that not the right package?

At any rate these subsequent errors seem to be unrelated except that they
are the result of changes in the same source files.

It looks like there is a discrepancy between halcmd_completion.c and the
associated header file, and further, a conditional in the make file which is
not being met to allow the file to compile. I haven't looked into it enough
to see what sets that conditional. Is there an alternate way of installing
readline-dev which will set it?

Thanks,
Eric


Forcing things isn't going to work.  You must have the readline-dev package
installed to have readline support, and the current code must have readline
support to build.

You have found one bug in the build system - if readline is required, the
configure step should stop and print an error message when it is missing.
Jeff has said he is going to fix that.

To make EMC2 compile, install readline-dev.

Making halcmd build correctly without readline support is possible but
complex and IMO not worth the trouble.  As Jeff has pointed out, many
Unix/Linux programs use readline, and its not unreasonable for EMC to depend
on it.
