[Scons-users] error 127

[William Deegan]

Peter,

If I had to guess, I’d say you’ve exceeded the maximum command line length with 5000 source files, and the shell is exiting with 127 status?

Hi,  

I'm getting an error 127 and have no idea why. It comes up after running  
a simple cat command. Here's the relevant sections of the SConstruct file:  

import os  

env = Environment(ENV=os.environ)  
consolidate_angles = Builder(action="cat $SOURCES > $TARGET")  
...  
env.consolidate(output_angles, angles_files)  

Where output_angles = 'some_file.csv' and angles_files = ['file1.csv',  
'file2.csv', ... ]. I've attached the output and the error I get. The  
array angles_files has about 5000 entries. If I reduce it to 3000,  
the build completes without errors. If I take entries 3000 - 5000,  
I also don't get any errors, leading me to believe that it's the length  
of the argument list that's problematic. If I run the corresponding  
command with all 5000 arguments on the command line, it works fine.  

Any ideas about why this happens and/or how to fix it? Like I said, if I  
copy and paste the command into bash, it works just fine. It's also the  
last command in the SConstruct file, if that makes any difference.
