Today I tried for the first time to build Perl 6 from source -- specifically Rakudo Star 2015.11 -- on my older Darwin/PPC. (I first tried to do so with 'rakudobrew', but that utility apparently has dependencies on more recent versions of 'git' than I can install on this machine.) Configuration failed -- but at a point so early in the process that I was surprised.

Here is what I called and got​:

##########
[rakudo] 545 $ cd rakudo-star-2015.11
[rakudo-star-2015.11] 546 $ perl Configure.pl --backend=moar --gen-moar
ATTENTION​: no --prefix supplied, building and installing to /Users/jimk/rakudo/rakudo-star-2015.11/install

Welcome to MoarVM!

Configuring native build environment ................... OK

Well, my compiler is definitely gcc. It's still capable of building perl-5.22.1 from source. I examined ./MoarVM/build/probe.pm and just above that point I saw C code to detect a C compiler. I extracted it, compiled it and ran it.

##########

$ cat try.c
#include <stdlib.h>

int main(int argc, char **argv) {
#ifdef __GNUC__
  return EXIT_SUCCESS;
#else
  return EXIT_FAILURE;
#endif
}

$ gcc -o try try.c

$ perl -e '$rv = system(qq{./try}); print "<$rv>\n";'
<0>
##########

So the C probe works by itself, but the program in which it is embedded fails. Any ideas?

Thank you very much.

But the shown exit of "0" would be correct, no?

I guess we want to show more information when we cannot compile the test scripts using the compiler we guessed....

My guess is that the PPC version of OS X probably still has the real
GCC as its compiler rather than clang as on more modern systems.

You could try looking for the config line which contains the definiton
of clang for OS X/darwin and changing it to gcc or if you are using
rakudobrew maybe something like

rakudobrew build moar --configure-opts=--moar-option=--cc=gcc

might work?

This will also be true of Intel-based Macs with Xcode 3.x or earlier

You could try looking for the config line which contains the definiton
of clang for OS X/darwin and changing it to gcc or if you are using
rakudobrew maybe something like

rakudobrew build moar --configure-opts=--moar-option=--cc=gcc

might work?

Unfortunately, that did not work. As I noted in my OP, it appears that rakudobrew is hard-wired to expect certain functionality in 'git' that is only found in versions of 'git' more recent than I can install on this machine. See attachment.

I then tried manual configuration. I tried 'perl Configure.pl --backend-moar --gen-moar' with various combinations of things like '--cc=gcc --link=gcc --ld=gcc'. Back when Rakudo was built on Parrot, those command-line switches would have been meaningful. But in this case I got no farther than Configure.pl's 'help' message. I inspected the code in Configure.pl and didn't see anything that suggested one could choose among compilers for those switches.

So it appears that Rakudo on moar is not buildable on this platform.

Thank you very much.

Can't we do something like this[^1] on darwin also?

gcc and llvm-gcc-4.2 are symlinks to clang in later versions of xcode, so
that should work.
