But since you keep the tarballs outside of the svn on a webserver somewhere you wouldn't normally expect the script to find the tarball, right? Unless you had already run this build once and downloaded it perhaps. And when you are done you check in any of changes then delete the working directory where you had the sources checked out and tarball downloaded into? Or do you just leave it all alone? I guess anyone working on it would know not to check in the tarball. -- Tracy R Reed Read my blog at http://ultraviolet.org Key fingerprint = D4A8 4860 535C ABF8 BA97 25A6 F4F2 1829 9615 02AD Non-GPG signed mail gets read only if I can find it among the spam. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

How do you know which tarballs go with which SRPMS and then how do you
put them back into place so you can build the RPM?

we use a package called rpmdevtools from fedora that has a script called
spectool which can be called like this:
#==
for f in `spectool -n -S -P *.spec | awk '{FS=" ";print $2}' \
| sed -e "s/.*\///g"`
do
# some source files are already here, so only download missing
# (compressed) ones.
if [ ! -e $rpmroot/SOURCES/$f ]; then
wget --http-user=$wget_user --http-password=$wget_passwd \
-P ../SOURCES http://$SERVER_NAME/sources/$f
fi
done

For CentOS-5, building an ISO uses the anaconda runtime and the
buildinstall command. Here is documentation on the buildinstall command:
