buildenvsetup

[robert lytton]

Hi,
I am running CE with a range of compiler versions, each with its own set_var.sh to set up the environment around it - which I am not currently calling.
So I was wondering if I could call the appropriate script (for the chosen compiler) prior to doing the compilation.
Looking at the codebase, it seems buildenvsetup() is where it should happen.

I also notice that the c++.amazon.properties sets a property (a class to use?).

Would anyone be able to explain the mechanism to me - please?

Can I set this per compiler.xyz.buildenvsetup   ?

Am I expecting too much from the codebase viz a lot of work needed on my part?!

Thank you.

Bob

Hi Bob,

The buildenvsetup is only used when linking, so might not be the right fit. We don't really have a good spot for setting environment variables directly.  We do support a "compiler-wrapper" which might work in your case, setting the wrapper to the compiler's set_var.sh. That said I can't see that we're using the compiler-wrapper in any code...but it would be worth a go. Something like:

compiler.mycompiler.exe=/path/to/exe

compiler.mycompiler.compiler-wrapper=/path/to/set_var.sh

the set_var might have to be changed to then run whatever args are passed to it...or maybe you'll need to write your own wrapper that calls set_var and then `exec "$*"` (or the bash magic to invoke onwards).

Hope that gives some clue: but in general launching a shell script to set env vars before running the compiler is not directly supported yet.

Cheers, Matt
