[bug#63393] [PATCH 0/2] Fix libstdc++.so and gcc-toolchain

[Simon Tournier]

Hi,

This patch fixes #63267 [1] by adding the output 'lib' to gcc-toolchain.  The
aim of gcc-toolchain is to be a battery included of GCC.  Maybe, this 'lib'
output could be directly included with the 'out'.  Well, I do not know.  WDYT?

For sure, it seems to help people using 'gcc:lib'. :-)

Well, another annoyance is that libstdc++ could be built using another
version.  Let for later. :-)

[bug#63393] [PATCH 0/2] Fix libstdc++.so and gcc-toolchain

[Kaelyn via Guix-patches via]

Hi,

I like the direction of this patch. However, if gcc-toolchain:lib is intended to provide the runtime libraries when the full compiler isn't needed, then I think the .a and .la files should be moved back to the main gcc-toolchain output (or a separate :static output) since they are for static linking and the .a files in particular can be sizeable.

Cheers,
Kaelyn

I would include gcc:lib in “out” (thus not adding a “lib” output to
‘gcc-toolchain’).

Yes, gcc:lib includes *.a and *.la, but those are already part of the
‘gcc-toolchain’ closure:

--8<---------------cut here---------------start------------->8---

However, I’d leave out gcc:debug because (0) it’s unrelated :-), (1)
‘gcc-final’ has no “debug” output, and (2) it’s really for a niche
(folks developing compiler plugins, typically).

I’d also leave out the /lib directory of Binutils, which is again rarely
useful.

WDYT?

Thanks,
Ludo’.

I don't have any strong opinions on the organization here of these
outputs, happy to defer to whatever others decide here. It would be nice
to have this sorted and taken care of before we forget about it :)

However, I think this message from Kaelyn only went to the bug number
(just saw that as I went to reply here) so I'm including it here:

[bug#63393] [PATCH 0/2] Fix libstdc++.so and gcc-toolchain

[Isaac van Bakel]

Hi,

Is there anything I can do to help (a version of) this patch get over 
the line?

I'm currently in a state when I want to use libgcc_s.so.1, which is only 
provided by gcc:lib, which doesn't set the library path properly. 
According to #25072, gcc-toolchain should support my use-case.

Thanks,

Isaac

Shows that the main output of GCC already keeps a reference to its "lib"
output within its closure.  It seems we could merge "lib" back into
"out" and simplify things?

No, because most packages depend on gcc:lib and we wouldn’t want them to
depend on all of gcc:

Thanks for putting this into perspective.  So out -> lib but lib !=
depend on out, which makes it useful to reduce the closure when used standalone.

Hi everyone,

(And adding another CC for Isaac, where I think their message went just
to the debbugs address, which goes to no one. Another victim of needing
a "wide reply" which is easy from e.g. Emacs but not obvious especially
for people who don't interact with debbugs much as I can attest to in my
earlier days. Anyway, that's yet another issue to improve elsewhere.)

To return to this, at the very least so I don't have to give the
incantation (which I got from someone else): guix shell -e '(list (@@
(gnu packages commencement) gcc) "lib")' to someone on IRC every few
days.

I'm sending a V2 of sorts, where it is the first patch from Simon (I had
to make a minor adjustment for it to apply cleanly now, please double
check!) and then my own very basic patch to solve the issue at hand:
just add gcc:lib to the inputs. I checked that building gcc-toolchain
works and includes libstdc++ and libgcc_s, which are the ones everyone
always asks about and assumes would be in gcc-toolchain.

What do we all think?

This is low impact and I don't think should negatively affect anything
so it would be great to get this pushed and close this finally :-)

Hope all is well!
John
