Compiling MEGAN3.2 with [ioapi2uam] error

Hi, everybody.
I’m compiling MEGAN3.2 with intel2022. when I make MEGANv3.2_Dec_2021 for . /make_all_programs.scr 64bit step, the following error occurs:

ifort -O3 -fixed -132 -traceback -qopenmp -xHost -Bstatic -I/home/tools/ioapi32/ioapi/fixed_src -I/home/tools/netcdf4/include -I/home/MEGAN/MEGANv3.2_Dec_2021/src/MGN2MECH/INCLDIR -o mgn2mech checkmem.o mgn2mech.o -L/home/tools/ioapi32/Linux2_x86_64ifort -lioapi -L/home/tools/netcdf4/lib -lnetcdff -lnetcdf
pgf90 -O -Mvect=sse -Mextend -Msecond_underscore -Bstatic_pgi -Mlfs -I/home/tools/ioapi32/ioapi/fixed_src -I/home/tools/netcdf4/include -c -o ioapi2uam.o ioapi2uam.f
make: pgf90：Command not found
make: *** [ioapi2uam.o] Error 127

At this point, my makefile file reads:
SHELL = /bin/sh
FC = pgf90
FFLAGS= -O -Mvect=sse -Mextend -Msecond_underscore -Bstatic_pgi -Mlfs
#FC = ifort
#FFLAGS = -O2 -fp-model precise -fpp -132 -mcmodel=large -convert big_endian
PROGRAM = ioapi2uam
LIBS = -L/home/tools/ioapi32/Linux2_x86_64ifort -lioapi
-L/home//tools/netcdf4/lib -lnetcdff -lnetcdf
INCLUDE = -I/home/tools/ioapi32/ioapi/fixed_src
-I/home/tools/netcdf4/include

RAW = (PROGRAM).o .f.o: (FC) (FFLAGS) (INCLUDE) -c -o @ <
.F.o:
(FC) (FFLAGS) (INCLUDE) -c -o @ < (PROGRAM): (RAW) (FC) (FFLAGS) (INCLUDE) -o (@) (RAW) (LIBS) clean: rm -f (PROGRAM)

When I changed FC=pgf90 in it to FC=ifort, I had a lot of problems with undefined references.

Looking forward to any replies you may have, thank you very much!

Variants of this have shown up multiple times here.

You need to add -qopenmp to the compile and link flags if your ifort version is at least 15, or -openmp for earlier versions.

Hi, thank you very much for your reply.
First of all my ifort version is 2021.6.0 and I compiled ioapi3.2 with -qopenmp added to the Makeinclude.Linux2_x86_64 ifort file as shown.
The above error is still generated in this case. I’m not quite sure exactly how I should proceed and look forward to your guidance and response.

You need to add -qopenmp to the compile and link flags of everything – including MEGAN.

Thanks for your reply, based on your answer I have managed to solve the problem.
