c++ - Portable way of linking libgfortran with CMAKE -


one of executables requires libgfortran.so. typically i'd add -lgfortran switch compile line , links automatically g++. however, i'm trying find library cmake using:

find_library(gfortran_library names gfortran) target_link_libraries(ncorr_test ${gfortran_library})

however, fails find library. turns out way has worked far if include entire library name so:

find_library(gfortran_library names libgfortran.so.3) target_link_libraries(ncorr_test ${gfortran_library})

then, link properly:

/usr/bin/c++ ... /usr/lib/x86_64-linux-gnu/libgfortran.so.3 ...

however, including whole .so.3 not portable. know of better way this? typically libraries need use installed in /usr/local/lib , searching library name without "lib" , extension works (i.e. find_library(fftw_library names fftw3) find libfftw3.a in /usr/local/lib fine).

edit:

find_library(gfortran_library names libgfortran.so) not work either. libgfortran.so.3 has worked far.

using locate libgfortran outputs:

/usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.a /usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.so /usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.spec /usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortranbegin.a /usr/lib/x86_64-linux-gnu/libgfortran.so.3 /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0 /usr/local/matlab/r2014a/sys/os/glnxa64/libgfortran.so.3 /usr/local/matlab/r2014a/sys/os/glnxa64/libgfortran.so.3.0.0 /usr/share/doc/libgfortran-4.8-dev /usr/share/doc/libgfortran3 /var/lib/dpkg/info/libgfortran-4.8-dev:amd64.list /var/lib/dpkg/info/libgfortran-4.8-dev:amd64.md5sums /var/lib/dpkg/info/libgfortran3:amd64.list /var/lib/dpkg/info/libgfortran3:amd64.md5sums /var/lib/dpkg/info/libgfortran3:amd64.postinst /var/lib/dpkg/info/libgfortran3:amd64.postrm /var/lib/dpkg/info/libgfortran3:amd64.shlibs /var/lib/dpkg/info/libgfortran3:amd64.symbols

edit2:

for i'll require user copy libgfortran.a on usr\local\lib directory

looks either miss dev package on linux distribution, should install .so link, or path such link located missing when cmake lookup. try find lingfortran.so link, located same place .so.3 is, if cannot find install missing dev package, if can check why path not included in cmake.

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
