Dear all, on CentOS 6 one could use -static-libgcc -static-libgfortran to obtain a binary which would run on other computers which don't have gfortran installed. On CentOS 7 one can install the libgfortran-static and libquadmath-static RPMs but the resulting binary _still_ requires /lib64/libquadmath.so as revealed by ldd. gfortran does not recognize an option like -static-libquadmath . libquadmath is required even for tiny programs which do not use high precision data types. Heavy use of Google did not bring any result. I tried with linker options -Wl,-Bstatic and so on, but without changes. So, can anyone tell me how to compile/link with gfortran a binary which does not have a requirement for libquadmath? If this is not possible, why are there libgfortran-static and libquadmath-static RPMs ? thank you, Kay
