py-numpy shows during compilation at lot of linker errors like this: //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__getf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__floatunditf@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__subtf3@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__multf3@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__unordtf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__lttf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__addtf3@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__gttf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__divtf3@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__letf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__cpu_model@GCC_4.8.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__netf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__floatditf@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__eqtf2@GCC_4.6.0' //usr/local/lib/gcc8/libgfortran.so.5: undefined reference to `__floatsitf@GCC_4.6.0' cc: error: linker command failed with exit code 1 (use -v to see invocation) NOT AVAILABLE but it builds to the end and installs.
