Either rename your package or the specfile. libscalapack2_2_0_2-gnu-mvapich2-hpc.armv6hl: W: shared-lib-calls-exit /usr/lib/hpc/gnu8/mvapich2/scalapack/2.0.2/lib/libscalapack.so.2.0.2 exit@GLIBC_2.4 This library package calls exit() or _exit(), probably in a non-fork() context. Doing so from a library is strongly discouraged - when a library function calls exit(), it prevents the calling program from handling the error, reporting it to the user, closing files properly, and cleaning up any state that the program has. It is preferred for the library to return an actual error code and let the calling program decide how to handle the situation. libblacs2-gnu-mvapich2-hpc.armv6hl: W: shlib-policy-missing-lib libblacs2_2_0_2-gnu-mvapich2-hpc-devel-static.armv6hl: W: shlib-policy-missing-lib libscalapack2-gnu-mvapich2-hpc.armv6hl: W: shlib-policy-missing-lib libscalapack2_2_0_2-gnu-mvapich2-hpc-devel-static.armv6hl: W: shlib-policy-missing-lib Your package starts with 'lib' as part of its name, but does not provide any libraries. It must not be called a lib-package then. Give it a more sensible name. 13 packages and 0 specfiles checked; 0 errors, 11 warnings.
