Hello all,<br><br>I'm having a trouble with installing SLEPc with the PETSC_ARCH variable.  I installed PETSc on my Linux as follows:<br><br>export PETSC_DIR=$PWD<br>export PETSC_ARCH=arch-linux-cxx-debug-real<br>export CXX="/usr/bin/mpicxx"<br>
export CC="/usr/bin/mpicc"<br>./configure --prefix=/home/aeronova/Development/local/lib/petsc/3.3-p2 --download-mpich=1 --download-blacs=1 --download-metis=1 --download-parmetis=1 --download-scalapack=1 --download-mumps=1 --download-umfpack=1 --with-clanguage=C++<br>
make PETSC_DIR=/home/aeronova/Development/local/share/petsc/3.3-p2 PETSC_ARCH=arch-linux-cxx-debug-real all<br>make PETSC_DIR=/home/aeronova/Development/local/share/petsc/3.3-p2 PETSC_ARCH=arch-linux-cxx-debug-real install<br>
make PETSC_DIR=/home/aeronova/Development/local/lib/petsc/3.3-p2 test<br><br>Then, I tried to install SLEPc as below<br><br>export SLEPC_DIR=$PWD<br>export CXX="/usr/bin/mpicxx"<br>export CC="/usr/bin/mpicc"<br>
export PETSC_DIR=/home/aeronova/Development/local/lib/petsc/3.3-p2<br>export PETSC_ARCH=arch-linux-cxx-debug-real<br>./configure --prefix=/home/aeronova/Development/local/lib/slepc/3.3-p1<br><br>, which gives an error:<br>
<br>Checking environment...<br>ERROR: PETSc is not configured for architecture arch-linux-cxx-debug-real<br><br>The error is confusing since I configured/installed PETSc with PETSC_ARCH=arch-linux-cxx-debug-real.  I'd appreciate if someone could help me with this problem. <br>
<br>Regards,<br>K. Lee.<br><br>
