[Simulavr-devel] joel committing now

[Joel Sherrill]

Hi,

I don't know what happened over the weekend but
I can now commit. YEAH!

I have committed all of my outstanding changes.
Most were very minor but let it build now
from CVS using autotools on Fedora and Cygwin.

Status:

+ Fedora appears to be executing fine. Builds
inside and outside of tree.  I haven't tested
make install yet.

+ The Cygwin executable core dumps VERY early
doing a "cout <<" on an argument string.  I
looked at the link command and played with it
by hand and couldn't get the problem to go
away.  I don't know why the first call to cout.

+ I added a TODO file since there are a number of
"wish" items that shouldn't pollute the problem
tracker.  Please read and update.

Questions:

+ Should the old src/Makefile and config.h be removed?

+ Should the .cvsignore's be in place to ignore the
plethora of autotools generated files?


When you check it out, you will have to do this:

./bootstrap
./configure
make
...

Please let me know if something doesn't work for you.
I will try to fix configure issues.
