Hello,  
I am trying to build sitecmp.exe (in /AMET\_v14/tools\_src/sitecmp). Here is what I did:

1. I change the FC flag in Makefile to pgf90 (as I am using pgi compiler) and IOAPI/NETCDF libraries path as my systems path (attached Makefile [Makefile.txt](https://forum.cmascenter.org/uploads/short-url/nO8SeYZ1QtLr3zoxyhOjR2MjZSv.txt) (2.7 KB) ).

**Modified path:**

EXEC = sitecmp\_v53.exe  
FC = pgf90  
CC = cc  
IOAPI\_INC = /root/Documents/softwares/ioapi3.2\_install/ioapi-3.2-20200828/ioapi/fixed\_src  
IOAPI\_LIB = /root/Documents/softwares/ioapi3.2\_install/ioapi-3.2-20200828/Linux3  
NETCDF\_LIB = /usr/local/netcdf-4.7.4/lib  
include\_path = -I (IOAPI\_LIB) \ -I (IOAPI\_INC)   
-I /usr/local/netcdf-4.7.4/include   
-I /usr/local/netcdf-4.7.4/include

**Here is the original path:**

EXEC = sitecmp\_v53.exe

FC = mpiifort  
CC = cc

LIB = /home/kappel/CMAQ\_Code/PROJECTS/CMAQv53r3/lib/x86\_64/intel18.0  
include\_path = -I (LIB)/ioapi/lib \ -I (LIB)/ioapi/include\_files   
-I (LIB)/netcdf/include \ -I (LIB)/netcdff/include

**Then I ran ‘make’ which gives me following error:**  
[root@adeq src]# make  
pgf90 -c -fixed -132 -O3 -fno-alias -mp1 -fp-model source -ftz -simd -align all -xHost -vec-guard-write -unroll-aggressive -I /root/Documents/softwares/ioapi3.2\_install/ioapi-3.2-20200828/Linux3 -I /root/Documents/softwares/ioapi3.2\_install/ioapi-3.2-20200828/ioapi/fixed\_src -I /usr/local/netcdf-4.7.4/include -I /usr/local/netcdf-4.7.4/include module\_envvar.F

This is the set of flags for Intel _ifort_, not Portland Group _pgf90_

You need to re-start the CMAQ build from scratch using compiler-case `pgi`.

Hi @cjcoats  
Thank you for your response. I am sorry I couldn’t understand what you mean by " you need to re-start the CMAQ build from scratch using compiler-case `pgi` ".

I actually ran CAMx which was built by using pgi compiler and all other subsequent software such as IOPAI, COMBINE, NETCDF etc., were also built by pgi compiler.

Please suggest.

AMET uses several of the CMAQ post-processors as tools for doing its own tasks, and generally the way it gets them is from a CMAQ-installation.

If you’re going to build them outside CMAQ, then you need a set of compile flags for the compiler you’re using; in my non-humble opinion, the way to get them ought to be to borrow them from the _ioapi/Makeinclude.$BIN_ that was used to build your I/O API installation. Be aware that they are written using a non-Standard-conforming “fixed-132” source-code format (that’s what the _ioapi/fixed\_src_ directory fir INCLUDE-files is about); the `E132` make-variable in the _Makeinclude.$BIN_ is your compiler’s flags for “fixed-132” source-code format…

So you’re using _BIN=Linux2\_x86\_64pg\_gcc\_nomp_ with _pgcc_ ?? Why? You should probably have used _BIN=Makeinclude.Linux2\_x86\_64pg_ instead.

Then for your $BIN you should have something like the following for your build:

FSTD = -Mextend -O2 -fast -V -Msecond\_underscore

Hello @cjcoats

I am using Makeinclude.Linux2\_x86pg as you can see the first line of this file here : [Makeinclude.Linux3.txt](https://forum.cmascenter.org/uploads/short-url/tSLSPrOSWxSW28jtujgkSJ2brrW.txt) (1.9 KB) .

\*\*While I was building ioapi; I modified following (as your suggestion in this post : [Airs2m3 error 2 while compiling ioapi3.2 - #4 by cjcoats](https://forum.cmascenter.org/t/airs2m3-error-2-while-compiling-ioapi3-2/2061/4) \*\*  
**1. In Makeinclude.$BIN file , I added `-DIOAPI_NCF4=1` to the `ARCHFLAGS` as i did not create my netcdf library with --disable-netcdf-4 --disable-dap.**  
**2. Used, FOPTFLAGS = -O2 -V -Mnosecond\_underscore in ioapi/Makeinclude.$BIN**

I couldn’t find " FSTD = -Mextend -O2 -fast -V -Msecond\_underscore" in $BIN (Linux3 folder in my system). Where can I find it? And how this is related to ‘sitecmp’ makefile (what changes to make in the makefile)?

Thanks in advance

OK, the _sitecmp_ compile doesn’t need any of the definitions (_"-D…_" stuff), and you are using the -M **no** second\_underscore (contrary to your post above).

The _FSTD_ stuff is one of the lines in your _sitecmp_ _Makefile_, not the I/O API _Makeinclude_ file; it needs to have a set of flags compatible with your _ioapi/Makeinclude.$BIN_

By the way, PGI changed the fixed-132-source-format from -_extend_ to -_Mextend_ at some point; that’s one difference; isn’t upward compatibility and the way it affects _Makefile_s wonderful ;-( ?

Hello @cjcoats

So, I changed FSTD flag in ‘sitecmp’ makefile ( [Makefile.txt](https://forum.cmascenter.org/uploads/short-url/uH0qGoIq1FRtwA9ZCXtw2brvsEs.txt) (2.7 KB) as your suggestion.  
**WARN = \*\*  
\*\* FSTD = -Mextend -O2 -fast -V -Msecond\_underscore**

\*\* #FSTD = -O3 -fno-alias -mp1 -fp-model source -ftz -simd -align all -xHost -vec-guard-write -unroll-aggressive\*\*  
\*\* DBG = -O0 -g -check bounds -check uninit -fpe0 -fno-alias -ftrapuv -traceback\*\*

Now, I am getting similar errors but only two (previously it was 10 [comment#1] , please see the original post for the comparison)

**al/netcdf-4.7.4/include module\_envvar.F**  
**pgf90-Error-Unknown switch: -fixed**  
**pgf90-Error-Unknown switch: -132**  
**make: \*\*\* [module\_envvar.o] Error 1**

Please help.

Thanks in advance

Find the _-fixed -132_ and remove them; the _-Mextend_ takes care of that.

Thank you so much. I can now compile ‘sitecmp.exe’ successfully.
