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

[Klaij, Christiaan]

Satish,

Fair enough, thanks for explaining. 

As far as I can tell the configure log (attached) gives the same error.

If the current version/format is not found, why not just say so
in the error message? Saying "unable to download" suggests
something's wrong with the internet connection, or file path.

Chris

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..
