Hello there. Im trying to compile and run Megan 2.1 with the pgf90 compiler. First all, I had the IOAPI and netcdf libraries already installed but with ifort. Is it necessary to reinstall them with pgf90? Besides that, I have compiling errors (I believe not related). ```auto Removing *.o Make all programs pgf90 -c -O -Mbyteswapio -Mextend -Mlfs -Msecond_underscore -I/home/sol/Build_CMAQ/src/ioapi/ioapi/fixed_src met2mgn.f pgf90 -c -O -Mextend -Mlfs -Msecond_underscore -I/home/sol/Build_CMAQ/src/ioapi/ioapi/fixed_src readpar.f NVFORTRAN-S-0188-Argument number 3 to open3: type mismatch (readpar.f: 332) 0 inform, 0 warnings, 1 severes, 0 fatal for readpar make: *** [makefile:36: readpar.o] Error 2 ``` I believe this is due to the fact that pgname is not defined in readpar.f. So I added:, in line 22 of readpar.f: ```auto CHARACTER*16, PARAMETER :: pgname = ‘READPAR’ ``` But then I got the following error: ```auto Removing *.o Make all programs pgf90 -c -O -Mbyteswapio -Mextend -Mlfs -Msecond_underscore -I/home/sol/Build_CMAQ/src/ioapi/ioapi/fixed_src met2mgn.f pgf90 -c -O -Mextend -Mlfs -Msecond_underscore -I/home/sol/Build_CMAQ/src/ioapi/ioapi/fixed_src readpar.f NVFORTRAN-W-0025-Illegal character (E2) - ignored (readpar.f: 22) NVFORTRAN-W-0025-Illegal character (80) - ignored (readpar.f: 22) NVFORTRAN-W-0025-Illegal character (98) - ignored (readpar.f: 22) NVFORTRAN-W-0025-Illegal character (99) - ignored (readpar.f: 22) NVFORTRAN-S-0087-Non-constant expression where constant expression required (readpar.f: 22) 0 inform, 4 warnings, 1 severes, 0 fatal for readpar make: *** [makefile:36: readpar.o] Error 2 ``` Im a bit confused here. After that Im having multiple errors of the kind: ```auto /usr/bin/ld: /home/sol/Build_CMAQ/src/ioapi/Linux2_x86_64ifort/libioapi.a(dscgrid.o): in function `dscoord_': dscgrid.f:(.text+0x92): undefined reference to `for_write_int_fmt' /usr/bin/ld: dscgrid.f:(.text+0xb5): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0xe0): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0xfc): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0x13d): undefined reference to `for_cpystr' /usr/bin/ld: /home/sol/Build_CMAQ/src/ioapi/Linux2_x86_64ifort/libioapi.a(dscgrid.o): in function `dscgrid_': dscgrid.f:(.text+0x1f9): undefined reference to `for_len_trim' /usr/bin/ld: dscgrid.f:(.text+0x255): undefined reference to `for_write_int_fmt' /usr/bin/ld: dscgrid.f:(.text+0x286): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0x2b1): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0x2c0): undefined reference to `for_len_trim' /usr/bin/ld: dscgrid.f:(.text+0x2de): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0x327): undefined reference to `for_cpystr' /usr/bin/ld: dscgrid.f:(.text+0x49d): undefined reference to `for_cpystr' /usr/bin/ld: dscgrid.f:(.text+0x596): undefined reference to `for_trim' /usr/bin/ld: dscgrid.f:(.text+0x5ee): undefined reference to `for_trim' /usr/bin/ld: dscgrid.f:(.text+0x626): undefined reference to `for_concat' /usr/bin/ld: dscgrid.f:(.text+0x6d3): undefined reference to `for_read_seq_fmt' /usr/bin/ld: dscgrid.f:(.text+0x75b): undefined reference to `for_read_seq_lis' /usr/bin/ld: dscgrid.f:(.text+0x7dd): undefined reference to `for_read_seq_lis' /usr/bin/ld: dscgrid.f:(.text+0x817): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0x851): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0x88b): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0x8c1): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0x8f7): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0x95c): undefined reference to `for_write_int_fmt' /usr/bin/ld: dscgrid.f:(.text+0x97a): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0x9a5): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0x9c2): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0xa45): undefined reference to `for_write_int_fmt' /usr/bin/ld: dscgrid.f:(.text+0xa67): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0xa92): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0xab2): undefined reference to `for_write_int_fmt_xmit' /usr/bin/ld: dscgrid.f:(.text+0xb29): undefined reference to `for_read_seq_lis' /usr/bin/ld: dscgrid.f:(.text+0xbbe): undefined reference to `for_read_seq_lis' /usr/bin/ld: dscgrid.f:(.text+0xbf8): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0xc32): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0xc6c): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0xca6): undefined reference to `for_read_seq_lis_xmit' /usr/bin/ld: dscgrid.f:(.text+0xce0): undefined reference to `for_read_seq_lis_xmit' ``` Maybe this is related to the fact that I have IOAPI compiled with ifort? Thank you very much for your help Kind regards Solange ---

> “Maybe this is related to the fact that I have IOAPI compiled with ifort?”: Yes, different Fortran compilers use different compiler-vendor-supplied libraries to implement things like the Fortran `WRITE` command (and sometimes even different libraries for things like different comiler-options!). That is why, for example, the different I/O API binary types are mostly classified by what Fortran compiler is being used… You need to compile everything with the same compiler set (and ideally the same compile-flags). See [https://www.cmascenter.org/ioapi/documentation/all\_versions/html/ERRORS.html#ccfc](https://www.cmascenter.org/ioapi/documentation/all_versions/html/ERRORS.html#ccfc) ---

Thank you for your answer. Do you know if it is possible to compile Megan with ifort and, if that is the case, where can I find how to replace all flags? ---

Hello there. So i recompiled everything with gfortran, but when I try to run the makefile I get a lot of errors, that I believe are not related to the compiler anymore. ```auto Removing *.o rm: No match. rm: No match.

Which version of _ **gfortran** _ ? I suspect version 10 or later, since that version started taking/mandating its own idiosyncratic interpretations of the Fortran-2018 Standard. Compare the I/O API’s _ioapi/Makeinclude.Linux2\_x86\_64gfort10_ with _ioapi/Makeinclude.Linux2\_x86\_64gfort_ to see what changes to the compile-flags you will need for recent _gfortran_s. ---

Thank you for your answer. Im actually using gfortran 9.4.0 so I believe that the “-fallow-argument-mismatch” flag is not needed. I checked the flags in _ioapi/Makeinclude.Linux2\_x86\_64gfort_ and I believe the flags Im using are correct. In the make file: ```auto ## Module-include-directory command MODI = -I E132 = -ffixed-line-length-132 MFLAGS = -ffast-math -funroll-loops -m64 # -Wall -Wsurprising -march=native -mtune=native OMPFLAGS = -fopenmp OMPLIBS = -fopenmp COPTFLAGS = -O3 ${MFLAGS} FOPTFLAGS = -O3 ${MFLAGS} FPPFLAGS = -DF90=1 FSFLAGS = -fno-automatic ARCHFLAGS = \ -DAUTO_ARRAYS=1 \ -DF90=1 -DFLDMN=1 \ -DFSTR_L=int \ -DIOAPI_NO_STDOUT=1 \ -DNEED_ARGS=1 PARFLAGS = ARCHLIB = -dynamic -L/usr/lib64 -lm -lpthread -lc ``` And Im using: ```auto FFLAGS = -O3 -ffixed-line-length-132 -ffast-math -funroll-loops -m64 -fopenmp ``` Am I missing something? ---

Hello there. Yes, it used the flags mentioned in this thread, but I had to make a few changes in some scripts to make it work correctly. These are the changes I did: ```auto cd IOAPI2UAM diff ioapi2uam.f ioapi2uam.f.old 165c165 < write(*,'(2(i9,f10.2))') ibdate,btime,iedate,etime --- > write(*,'(2(i,f))') ibdate,btime,iedate,etime 299c299 < write(*,'(a,2(i9,f10.2))')'Writing ',ibdate,btime,iedate,etime --- > write(*,'(a,2(i,f))')'Writing ',ibdate,btime,iedate,etime ``` ```auto cd ../MET2MGN diff readmcip.f readmcip.f.old 34c34 < logical MCIP_rad,SAT_par,ENVYN,INITIAL_HOUR,ifsoil,lfirst --- > logical MCIP_rad,SAT_par,ENVYN,INITIAL_HOUR,ifsoil 383c383 < if(ifsoil) then --- > if(isoil) then diff readpar.f readpar.f.old 15,20c15,16 < INTEGER, parameter :: mx=350 < INTEGER, parameter :: my=410 < INTEGER, parameter :: mz=30 < INTEGER, parameter :: nlat=61 < INTEGER, parameter :: nlon=121 < --- > parameter mx=350,my=410,mz=30 > parameter nlat=61,nlon=121 ``` ```auto cd ../TXT2IOAPI diff cnvt_efs.F cnvt_efs.F.old 51c51 < INTEGER :: XREF(MXTCOL) --- > INTEGER, XREF(MXTCOL) diff cnvt_pft.F cnvt_pft.F.old 55c55 < INTEGER :: XREF(NFLD) --- > INTEGER, XREF(NFLD) diff cnvt_lai.F cnvt_lai.F.old 55c55 < INTEGER :: XREF(NFLD) --- > INTEGER, XREF(NFLD) ``` Hope it works! ---

By the way, have you made any changes to the EMPROC compilation? I encountered a warning when compiling: canopy.f:166:43: 166| & Qdiffv,Obeamn, Qdiffn, Cantype, Canopychar, Sunfrac, Warning:Dummy arguement ‘canpychar’ with INTENT(IN) in variable definition context(actual arguement to INTENT=OUT/INOUT) at (1) Looking forward to your reply ---

Hello. I dont remember encountering this problem. I believe that depending on which version compiler is being used, errors and warnings can be different. What I get from this warning is that canpycar is declared as intent(in) and that means that that variable should not be updated but it somehow is somewhere in the script. Maybe declaring it as intent(inout) would solve it. ---

Hello there. I’m also trying to run Megan 2.1. met2mgn is giving me a lot of problems compiling it. I’m using gfortran compiler instead of pgf90, ioapi 3.2 and netCDF 4.9.2. I have the next compiling errors in met2mgn when I try to run make clean and make -f Makefile.met2mgn.64bit: fields.inc:27:72: 27 | real qtmp(mnxc,mnyc,mnz), ptmp(mnxc,mnyc,mnz), tktmp(mnxc,mnyc,mnz) | 1 Error: Expected another dimension in array declaration at (1) fields.inc:38:72: 38 | real pwg(mnxc,mnyc,mnzc), cod(mnxc,mnyc,mnzc), pwtr(mnxc,mnyc,mnzc) | 1 Error: Expected another dimension in array declaration at (1) fields.inc:47:26: 47 | & cod,rain,pstar,tsfc,rground,pblc,z0c,topcx,lucx | 1 Error: Symbol ‘cod’ at (1) has no IMPLICIT type fields.inc:31:46: 31 | common /tmpfld/ utmp,vtmp,ttmp,qtmp,ptmp,tktmp,ztmp,cwtmp,prtmp, | 1 Error: Symbol ‘ptmp’ at (1) has no IMPLICIT type; did you mean ‘pgtmp’? fields.inc:46:70: 46 | common /camxfld/ uac,vac,tac,qac,pac,zhc,rkv,tkc,cwc,pwr,pws,pwg, | 1 Error: Symbol ‘pwg’ at (1) has no IMPLICIT type; did you mean ‘pws’? fields.inc:31:41: 31 | common /tmpfld/ utmp,vtmp,ttmp,qtmp,ptmp,tktmp,ztmp,cwtmp,prtmp, | 1 Error: Symbol ‘qtmp’ at (1) has no IMPLICIT type; did you mean ‘ttmp’? fields.inc:31:52: 31 | common /tmpfld/ utmp,vtmp,ttmp,qtmp,ptmp,tktmp,ztmp,cwtmp,prtmp, | 1 Error: Symbol ‘tktmp’ at (1) has no IMPLICIT type; did you mean ‘ttmp’? make: \*\*\* [Makefile.met2mgn.64bit:30: met2mgn.o] Error 1 Also, I would like to use data from ERA5 for the meteorological input, is that possible?do you have any idea on how to adapt met2mgn for that kind of input? or even on how to process it to convert the data into the format required for MEGAN? because I tried using CDO to change the name of the variables and do some calculus but it didn’t work when I ran emproc. That’s what made me notice met2mgn wasn’t compiled properly. Thanks in advance for your help If you need any additional information please let me know It’s the first time I’m using the model so I’m kind of lost and I really need to get that done
