Dear,

C and C++ have both C_INCLUDE_PATH and CPLUS_INCLUDE_PATH
such env var is really helpful I would like to know if ldc has a D_INCLUDE_PATH ?

if not, is it possible to introduce this feature?

thanks


Best regards

No and I wouldn't approve of such magic. DFLAGS can be used to a similar effect when using ldmd2.

I agree we shouldn't add that hardcoded into the compiler.
Possibly we could add support for environment variables in ldc2.conf.

Such env var would be helpful on HPC computing. Indeed most of worldwide grid use the "environment module" -> https://github.com/cea-hpc/modules
I found this article which describe well this technology: https://www.admin-magazine.com/HPC/Articles/Environment-Modules

In short to allow multiple version of same tools, "environment module" use PATH, C_INCLUDE_PATH, LD_CONFIG_PATH, PYTHONPATH and others to reach this goal.

But in D that seem not easy to do it as this env var do not exist.

Is DFLAGS not sufficient for what you want?

I will give a try with it


Thanks
