SLEPc for Debian ---------------- This source package includes the following binary packages: libslepc-real3.19 - shared libraries (real number support) libslepc-real3.19-dev - static libraries, shared links, and header files real number support (latest v3.19) libslepc3.19-dev-examples - examples slepc3.19-doc - documentation The following binary packages include support for complex numbers: libslepc-complex3.19 libslepc-complex3.19-dev slepc-dev installs the latest version (real number support). With slepc-dev installed (or libslepc-real3.19-dev or libslepc-complex3.19-dev), you can build programs against it two ways: 1. Standard build convention: use -I/usr/include/slepc for headers and link to optimized libraries in /usr/lib, so your resulting binaries will only depend on libslepc3.19. 2. PETSc/SLEPc build convention: modify the makefile from the one in their examples directory and build with PETSC_DIR=/usr/lib/petsc PETSC_ARCH=`petscarch` \ PETSC_LIB_DIR=$PETSC_DIR/$PETSC_ARCH/lib SLEPC_DIR=/usr/lib/slepc \ SLEPC_LIB_DIR=$SLEPC_DIR/$PETSC_ARCH/lib make The libslepc3.19-dev-examples package comes with the SLEPc examples in /usr/share/doc/libslepc3.19-dev-examples/examples/ Copy as needed and use the PETSc/SLEPc build convention make command above. See also README.Debian in the PETSc package for more related notes. Alternative SLEPc Versions -------------------------- The preferred version of SLEPc (real or complex, the preferred minor patch version) can be controlled using alternatives: update-alternatives --config slepc (other slepc alternatives are listed below) Or PETSC_DIR and SLEPC_DIR can be set to the preferred version located under /usr/lib/petscdir and /usr/lib/slepcdir. The full set of SLEPc alternatives is: slepc - set the default version (real or complex) of SLEPc (/usr/lib/slepc) libslepc_real.so - set the default SLEPc shared library with real number support libslepc_complex.so - set the default SLEPc shared library with complex number support slepc3.19 - set the preferred version (real or complex) of SLEPc 3.19 (/usr/lib/slepcdir/3.19) libslepc.so.3.19 - set the preferred version (real or complex) for the shared library of SLEPc 3.19 (likewise for other major versions in place of 3.19) ===== 64-bit indexing ===== Support for 64-bit indexing is provided in libslepc64* packages. This enables SLEPc to be used on larger systems with more than 2 billion elements.
