[Libmesh-users] Installation Error of Libmesh v1.0.0 on Linux Arch

[Dafang W. <daf...@jh...>]

Hi,

I got the following error when installing Libmesh v1.0.0 with PETSC 
v3.6.4/3.5.4 (neither Petsc worked). I am installing an older version of 
Libmesh because only that version is compatible with my user code.

I put the error message and config.log below. My question is that I am 
not sure whether this error was due to the version conflict between 
Libmesh and Petsc, because this error didn't occur when I was installing 
the latest version of libmesh/petsc. (Unfortunately the latest version 
is incompatible with my user code.)

Any advice would be appreciated. I only found 3 threads on Google 
regarding this error.

Cheers,
Dafang
