[petsc-users] error with wrong tarball in path/to/package

[Satish Balay]

Always look in configure.log to see the exact error.

No - configure does not do checksums - but it expcects the package to
be in a certain format [and this can change between petsc versions].
So if you are using a url from petsc-3.5 - with 3.7 -- it might not
work..

So for any version of petsc - its always best to use the default
externalpacakge URLs [for some externalpacakges - different versions
might work - but usually thats not tested].

configure attempts to determine the exact error - and attempts to
print appropriate message - but thats not always possible to figureout
- so its best to check configure.log to see the exact issue..

Note: to print the 'wrong version message' - it needs to know & keep
track of the previous versions [and formats - if any] - and thats not
easy.. All it can do is check for - current version/format is found or
not..
