Re: How to test if a file is existed or not?

[Peng Yu]

Hi Philip,

What if I want to either include some file or define some other variables depending on whether the file is existed or not?

For example, I want something like this. Therefore, I still need to test whether a file exist or not. Can this be done in gmake?

#if file exist
include file
#else
VAR1 = bla bla
VAR2 = bla bla
#endif

Thanks,
Peng

Hi Philip,

I missed that part. Now I see that I should use -include.

Thanks,

If you mean "include" as in "make part of the build" then the
$(wildcard) function may do the trick.

If you mean 'include' in the "treat as additional Makefile contents",
then the answer is yes, and it is described on the same page in the
GNU make info manual as the normal "include" directive.
