Dear Sir:  
I am using CMAQ5.3 on the ubuntu18.04, I have compiled CCTM to get CCTM\_v53.exe. My Compiler is gcc 7.4.0, when i am going to run benchmark data(2016\_12SE1),the command line Tip is: “source: Too many arguments.”  
Could you tell me what should I do?  
$ ./run\_cctm\_Bench\_2016\_12SE1.csh gcc 7.4.0  
Start Model Run At Mon Nov 4 14:14:55 CST 2019  
source: Too many arguments.

Best wishes  
MingHui Chou

I believe the error “source Too many arguments” is telling you that the script is only expecting one input, rather than 2.  
Please try runnning without the version number  
./run\_cctm\_Bench\_2016\_12SE1.csh gcc

I have the same error as Minghui, and running without the version does not work either. Could you help with this?

Please examine the run script for CMAQv5.3.

The version of the run script that I have does not expect any inputs, as it uses environment variables to set the compiler and version number. This approach has been modified over time.

```auto
#> Choose compiler and set up CMAQ environment with correct 
#> libraries using config.cmaq. Options: intel | gcc | pgi
 if ( ! $?compiler ) then
   setenv compiler gcc
 endif
 if ( ! $?compilerVrsn ) then
   setenv compilerVrsn Empty
 endif

#> Source the config.cmaq file to set the build environment
 cd ../..
 source ./config_cmaq.csh $compiler $compilerVrsn

```

If your run script looks identical to the above, then please try running the script without any inputs as follows:

```auto
./run_cctm_Bench_2016_12SE1.csh 

```

Thanks liz, my run script looks identical to yours, and i tried running it without any inputs but it still does not work. Attached is my run script.

Can you try to modify the line

```auto
cd ../..
source ./config_cmaq.csh $compiler $compilerVrsn

```

to

```auto
cd ../..
source ./config_cmaq.csh $compiler

```

I can’t seem to reproduce your error, but perhaps this will solve it.
