alltypes.h error: conflicting types for 'size_t'

alltypes.h error: conflicting types for 'size_t'

[Daniel G.]

Hi all,

I'm building a multilib cross-compiler toolchain based in musl. And this is
roughly the plan:

linux-4.18.16
gmp-6.1.2 / mpfr-4.0.1 / mpc-1.1.0
binutils-2.31.1
gcc-8.2.0 First Pass
musl-1.1.20 (git source)
gcc-8.2.0 Second Pass

During the second pass of gcc a make error occurs for the
all-target-libgcc, and it seems to be related to the mussl
include/bits/alltypes.h, due to a conflicting types for 'size_t'. As a
consequence, generic-morestack.c can't compile (I guess)

At the end of this mail you can find the output of the make process.

I would appreciate any help to solve this issue.

Thank you in advance for your cooperation.

================
Daniel Gutiérrez

it is not ideal that both musl and gcc headers get
included with the typedefs, but i don't see why
they are in conflict:

both typedefs should expand to 'unsigned long'
(if not then something is very wrong)

you can try to rerun that build command with -E
instead of -c to see the actual size_t definitions
after macro expansion.

(i assume multilib breaks it somehow, but i don't
see how)

It's a bug in the gcc build process if the gcc-provided headers get
used at all with musl. This might be multilib-dependent. I've not
tested with multilib since it definitely does not work with musl
anyway (gcc's multilib assumes the same include dir works for both of
the 'corresponding' 32- and 64-bit archs, which is not the case for
musl).

i think the same happens in mcm when libgcc is built, because
of the -B.../gcc -I.../gcc cflags, gcc/include and gcc/ are
in the search path before the libc headers, but the typedefs
happen to not collide.
