Trying to compile ioapi3.2 on cluster running two 64-core AMD Epyc “Milan” processors. Im using Intel compiler and admin. installed netCDF C and netCDF fortran also compiled with intel (and curl and MPI) with netCDF4. Following the CMAS install instructions I used DEFINEFLAGS = -DIOAPI\_NCF4=1 (since netCDF4 was not disabled) and comment out OMPFLAGS = #-qopenmp, OMPLIBS = #-qopenmp in Makeinclude.Linux2\_x86\_64ifort. ioapi looks to compile fine, but error chain pops up once m3tools starts to compile. I read and tried the fixes for the same problem to no avail. ChatGPT says the error are do to a linkage problem with netCDF, but all AI suggested fixes failed Partial make.log when the trouble starts make[1]: Leaving directory ‘/depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/ioapi’ (cd /depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/m3tools ; make BIN=Linux2\_x86\_64ifort all) make[1]: Entering directory ‘/depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/m3tools’ cd /depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/Linux2\_x86\_64ifort; ifort -auto -warn notruncated\_source /depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/Linux2\_x86\_64ifort/airs2m3.o -L/depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/Linux2\_x86\_64ifort -lioapi “`nf-config --flibs` `nc-config --libs`” -o airs2m3 /depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/Linux2\_x86\_64ifort/libioapi.a(init3.o): In function `init3_': init3.F90:(.text+0x6a): undefined reference to `nf\_inq\_libvers\_’ /depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/Linux2\_x86\_64ifort/libioapi.a(open3.o): In function `open3_': open3.F90:(.text+0xc01): undefined reference to `nf\_close\_’ /depot/gmichals/apps/Greg\_CMAQ/ioapi-3.2/Linux2\_x86\_64ifort/libioapi.a(opnfil3.o): In function `opnfil3_': opnfil3.F90:(.text+0xb0): undefined reference to `nf\_open\_’ opnfil3.F90:(.text+0xe9): undefined reference to `nf_get_att_int_' opnfil3.F90:(.text+0x117): undefined reference to `nf\_get\_att\_int\_’ opnfil3.F90:(.text+0x16a): undefined reference to `nf_get_att_int_' opnfil3.F90:(.text+0x198): undefined reference to `nf\_get\_att\_int\_’ opnfil3.F90:(.text+0x1c6): undefined reference to `nf_get_att_int_' /depot/gmichals/apps/Greg_CMAQ/ioapi-3.2/Linux2_x86_64ifort/libioapi.a(opnfil3.o):opnfil3.F90:(.text+0x1f4): more undefined references to `nf\_get\_att\_int\_’ follow ---

So what does that **entire line that generates the error** look like ?? ---

Found them in the ioapi3.2 Makefile not in m3tools Makefile looks to have been the problem! Thanks ive come to loathe the plethora of Makefiles, Makefile.seds over the past 3 days!
