[Libmesh-users] Yet another linking trouble (cygwin)

[Denis D. <dan...@ya...>]

Hi,

The theme of compilation and linking is the most popular in the last
month...

I try to set up libmesh 0.4.2 on the following configuration:
cygwin + gcc3.3 + petsc(mpiuni)
./configure --enable-reference-counting --enable-perflog
--disable-laspack --disable-tecplot --disable-shared

I can build library, but when i try to compile and run an example
program, an error appears in the form

(output of make all -n for example 1)
echo "Linking "ex1"..."
g++ -O2 -felide-constructors -DNDEBUG -funroll-loops -fstrict-aliasing

It seems  all the necessary libs are included in command line
(particular libmpiuni.a ans petsc), however Petsc_MPI_Finalize() and
MPIUNI_Memcpy() are not found.
Any suggestion how get it working in this configuration (without
laspack)?


Best regards
