Re^5: Defining an XS symbol in the Makefile.PL (SOLVED)

Are the % characters appearing in the generated Makefile where they should be?

Yes - if I've specified one "%", then only one appears in the generated Makefile - irrespective of the flavour of make.
If I've specified "%%", then "%%" appears in the generated Makefile - irrespective of the flavour of make.

When make prints the command it is issuing, is the % present as it should be?

Yes - according to what's appearing on the screen as the build is proceeding, the actual command that's being run is as expected for the particular value I've given to CCFLAGSEX, irrespective of the flavour of make.

There were problems (with which I did not persevere) in getting that Inline::C script to run in my (MSYS2) bash shell using my Windows perl. The process hangs (due to issues with backslashes in paths, I think):

However, I've just found another Windows GNU make (provided by Strawberry Perl):

GNU Make 4.2.1
Built for x86_64-w64-mingw32

[download]

and using that particular build of make makes the issue go away !!!
That's a good enough indicator for me that my problems arose because I was using a buggy version of GNU make.

Thanks for the continuing assistance, guys.
Further conversation/thoughts/observations are certainly welcome, but I'm now marking this as solved.

Cheers,
Rob

Considering that your `Inline::C` test is hanging just after producing a cmd.exe startup banner and prompt, I would file this whole mess under the category of "Windows": evidently make is starting a shell to run a command but the shell is waiting for input (probably from `NUL:`) instead of running the intended command.

To me, it just illustrates that one shouldn't execute a native windows perl.exe inside an MSYS2 bash shell. That it failed to run to completion in that shell is not worthy of any concern. Cheers, Rob	[reply]
