Re: Build failure due to .incbin
[Ulrich, you're the maintainer for the SPU stuff, right?]
No, I am.
Ah okay, I should have known. Sorry about that.
gcc -c -Wa,-I,../../../src/ld/emultempl -o spu_inc.o
../../../src/ld/emultempl/spu_inc.s
../../../src/ld/emultempl/spu_inc.s:6:Unknown pseudo-op: .incbin
This file is compiled with the native assembler, and it
doesn't know .incbin . Please fix :-)
Sigh. Built-in support for spu overlays requires that we smuggle an
spu object file into ld somehow. gas .incbin is one way, another is
"objcopy -I binary -O <host_format>", a third is "ld -r -b binary".
A fourth option is to use a "bin2c" kind of build tool,
that converts a binary file into a C array that can then
be compiled into whatever you want.
All of these methods rely on host tools to some extent. I guess
the thing to do is simply not support a built-in overlay manager
if the host tools are deficient.
Also, is there a way to say --enable-targets=all
--oh-but-not-these-few?
Nope.
Too bad. Well not many people seem to use targets=all so there's
not much point in adding something I suppose.

Except those symbols need to have an extra underscore in the
assembler source file, with the Darwin assembler. (Sorry I
didn't mention this earlier, I only noticed after I sent the
mail).
