How to Run autoconf on sim/erc32 directory

How to Run autoconf on sim/erc32 directory

[Joel Sherrill]

Hi

I have a patch I want to try on Cygwin but I don't seem to have the proper
auto-fu to generate configure.

Help on the auitoconf command appreciated.

Thanks.

Hi Joel,

I take it you have changed sim/erc32/configure.ac (or another file that 
goes in making sim/erc32/configure) and you want to re-generate 
sim/erc32/configure?  In that case, you just need to go in the sim/erc32 
and run "autoconf" ("autoconf -f" may sometimes be useful if autoconf 
doesn't realize some things have changed).

You should use the same version of autoconf as the version that 
generated the current configure.  As you can see in the header, this is 
autoconf 2.69:

   # Generated by GNU Autoconf 2.69.

Some Linux distributions have local patches to autoconf, which results 
in spurious diffs when re-generating configure.  If that happens, try to 
build and use autoconf from upstream.

Thanks,

Simon

I decided to take a shot that Cygwin was the trouble. I moved the patch to
Linux, ran autoconf and copied the configure back to Cygwin. My change
worked fine.

This only depended on autoconf 2.69 and the RTEMS version has
no patches.

Thank you. Patch coming shortly
