Command line too long

Command line too long

[Kevin Gallo]

I am using CSL 1.12 (the native code compiler) and I have the problem
that my command line gets too long for my shell to handle.  I see no
solution to the problem other than trying to shorten the command line
but this undesirable.  Is there a way to partially link several modules
to do the compile in stages?  Also it would be nice if CSL could support
response files (files with the command line parameters) to allow for
unlimited argument lengths.

Thanks,

Kevin

You can use libraries as intermediate steps:

        cslopt -a -o templib1.cmxa <many .cmx files>
        cslopt -a -o templib2.cmxa <more .cmx files>
        cslopt -o myexec templib1.cmxa templib2.cmxa <remaining .cmx files>

This takes a little longer to link because of the extra I/O involved
with building the libraries, but it should work.

Modern Unix systems set the ARG_MAX limit so high (128 kbytes under
Linux, 40 kbytes under OSF1) that I was hoping this would not be necessary.
