As the initial message mention two issues which are already addressed on other topics (see links after): I’m going to rewrite previous messages to focus on `FINDLOC` function subject. > [@Fortran preprocessing converts \`\_/\*\*/PRECISION\` to problematic \`\_ sp\`](https://nemo-ocean.discourse.group/t/fortran-preprocessing-converts-precision-to-problematic-sp/108): > > Hi all, I am currently getting installed on a new supercomputer and I encounter issues regarding pre-compilation. Some subroutine names have a particular syntax finishing by \_/\*\*/PRECISION (ex: SUBROUTINE lbc\_nfd\_/\*\*/PRECISION). The comment /\*\*/ is used to make sure the compiler does recognize that PRECISION is a key work that must be replaced by sp for instance. However, the pre-compiler output in /BLD/ppsrc/nemo/ yields \_/\*\*/sp (ex: SUBROUTINE lbc\_nfd\_/\*\*/sp). During the compilation, m… > [@\[v4.2.x\] Compilation: no \`xios\_send\_field\` subroutine](https://nemo-ocean.discourse.group/t/v4-2-x-compilation-no-xios-send-field-subroutine/265): > > I can compile NEMO-4.0.1 with xios-2.5.
