Source: slepc Version: 3.6.1.dfsg1-1 Severity: serious Justification: fails to build from source (but built successfully in the past)
Builds of slepc in minimal environments (such as on the autobuilders) have been failing with errors of the form Checking environment... done Checking PETSc installation... ERROR: Unable to link with PETSc ERROR: See "installed-i386-linux-gnu-real/lib/slepc/conf/configure.log" file for details debian/rules:149: recipe for target 'override_dh_auto_install' failed make[1]: *** [override_dh_auto_install] Error 1 make[1]: Leaving directory '/«PKGBUILDDIR»' debian/rules:101: recipe for target 'binary-arch' failed make: *** [binary-arch] Error 2 dpkg-buildpackage: error: fakeroot debian/rules binary-arch gave error exit status 2 I was able to reproduce the problem on a porterbox (amd64, as it happens), and found the issue to be that it was explicitly linking against libraries that were neither direct nor indirect build dependencies: mpicxx -Wl,-z,relro -Wl,--no-as-needed -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -o checklink checklink.o -L/usr/lib/petscdir/3.6.2/x86_64-linux-gnu-real/lib -L/usr/lib/petscdir/3.6.2/x86_64-linux-gnu-real/lib -lpetsc_real -ldmumps -lzmumps -lsmumps -lcmumps -lmumps_common -lpord -lumfpack -lamd -lcholmod -lklu -L/usr/lib -lHYPRE_utilities -lHYPRE_struct_mv -lHYPRE_struct_ls -lHYPRE_sstruct_mv -lHYPRE_sstruct_ls -lHYPRE_IJ_mv -lHYPRE_parcsr_ls -lsuperlu -lscalapack-openmpi -llapack -lblas -lssl -lcrypto -lptesmumps -lptscotch -lptscotcherr -lfftw3 -lfftw3_mpi -lm -L/usr/lib/openmpi/lib -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/usr/lib/x86_64-linux-gnu -L/lib/x86_64-linux-gnu -lmpi_f90 -lmpi_f77 -lgfortran -lm -lgfortran -lm -lquadmath -lm -lmpi_cxx -lstdc++ -L/usr/lib/openmpi/lib -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/usr/lib/x86_64-linux-gnu -L/lib/x86_64-linux-gnu -L/usr/lib/x86_64-linux-gnu -ldl -lmpi -lhwloc -lgcc_s -lpthread -ldl /usr/bin/ld: cannot find -lssl /usr/bin/ld: cannot find -lcrypto /usr/bin/ld: cannot find -lgfortran Could you please take a look? Given that Debian builds PETSc as a shared library, it shouldn't be necessary to list any other libraries on the command line. However, if the build system makes that hard to avoid, please compensate by listing libgfortran-5-dev and libssl-dev in Build-Depends. (It's unfortunate that there's no generic libgfortran-dev, though I suppose you could list gfortran.) Either way, please confirm with pbuilder or the like that there aren't any further errors in minimal environments. Thanks!
