[petsc-dev] A couple of other notes from the Cygwin64 install

[Aron Ahmadia]

cygcheck is a bit of a swiss army knife, as I said a bit earlier:

cygcheck.exe will check that all of the DLLs for a DLL or .exe are on the
path for you and complain otherwise.

Here's how to use it:

cygcheck.exe ~/proteus/hashstack/opt/profile/vuku/bin/cygpetsc.dll

using ldd on the same dll doesn't reveal the environment errors.

I can't make heads or tails of your error, cygcheck might be able to
diagnose it.
