Discussion:
[musl] ctype_base.h. Several errors "was not declared in this scope"

Hi all,
I keep on trying to build a cross-compiler toolchain based in musl. I've
left the idea of a multilib one due to conflicting types error (I wrote a
few days ago about alltypes.h conflicting types for 'size_t').

Now, also during the second pass of gcc, I've found three make errors. I've
been able to patch two of them (one about the definition of PATH_MAX and
another regarding __GLIBC_PREREQ).

The third one seems to be more complicated, and affects the compilation of
libstdc++-v3. At the end of the mail you can find a bunch of errors on variables not
declared in the scope.

Any help will be welcomed, and again, thank you for your cooperation.

Hi all,
I keep on trying to build a cross-compiler toolchain based in musl. I've
left the idea of a multilib one due to conflicting types error (I wrote a
few days ago about alltypes.h conflicting types for 'size_t').
This is likely due to multilib, which needs to be disabled. musl does
not do the gcc multilib model of using the same set of headers for
pairs of 32- and 64-bit archs that correspond to each other. If you
want both you need completely separate toolchains for each. Use
--disable-multilib.

Now, also during the second pass of gcc, I've found three make errors. I've
been able to patch two of them (one about the definition of PATH_MAX and
another regarding __GLIBC_PREREQ).
This sounds like you're building gcc for a glibc target and not for
musl, but it's hard to know for sure with such a vague description.
Make sure you've specified x86_64-linux-musl (or whichever arch) on
the configure command line.

I'm confused why there's a second pass if you're building a cross
compiler, though. Multipass only makes sense for a native compiler.

The third one seems to be more complicated, and affects the compilation of
libstdc++-v3. At the end of the mail you can find a bunch of errors on variables not
declared in the scope.
This definitely indicates that you're building gcc for a glibc target
and not for musl. The files that the errors occurred in are only for
use with glibc.
