This is a new function in GCC 9, so maybe you are linking with the wrong library version? You can use nm (or nm -D) to look for symbols in a shared library. You can use "gcc --print-file-name=libgfortran.so" to find the library file that gcc is using by default. The gcc-9 compiler should point at a gcc-9 version of this library. You can add -v to a compiler command to see what the compiler driver is doing, and -Wl,--verbose to see what the linker is doing, to see exactly which libgfortran.so file that the linker is using. Jim
