[musl] Compile gcc-12 with musl and report errors

Hi：
   I installed the Alpine Linux system on the x86_64 platform, and exposed a problem when compiling gcc 12 using musl (master branch) in this system：
​/usr/lib/gcc/x86_64-alpine-linux-musl/12.2.1/../../../../x86_64-alpine-linux-musl/bin/ld: d/common-outbuffer.o: in function `_D3dmd6common4file__T11FileMappingThZQq6__ctorMFNbNcxPaZSQCdQCcQBy__TQBwThZQCc':
outbuffer.d:(.text+0x29f): undefined reference to `mmap64'
 
I uploaded more detailed logs to gcc_ build_ Error.log file，and other information is as follows：
1、linux-lts（kernel）version：6.1.10-r0
2、gcc version：12.2.1_git20220924-r9
3、binutils version：binutils-2.40-r4
4、musl：master branch and commit is f47a8cdd250d9163fcfb39bf4e9d813957c0b187

I suspect that the error is caused by the difference of the musl code，When I checked musl source, I found that there was a big difference between the master branch code and the v1.2.3 version code. For example, a large number of weaks_alias were removed during the 246f1c811448f37a44b41cd8df8d0ef9736d95f4 commit，include “weak_alias(mmap, mmap64);” in src/mman/mmap.c.

I want to compile gcc 12 based on musl (master branch). and I try to apply the old code to the latest branch, but this seems to be not a wise choice. so I share this error and look forward to some suggestions from the community experts.

I'm Looking forward to your reply,thanks.

yes, as that commit says, this was intentional. code is _not_ meant to call
these *64 functions that were removed- code should unconditionally call `mmap`
and use -D_FILE_OFFSET_BITS=64 (for C) . so, gcc (the D frontend here) needs fixing.

specifically, it's libphobos/libdruntime/core/sys/posix/sys/mman.d ,

where:

 else version (CRuntime_Musl)
 {
     static if (__USE_LARGEFILE64) void* mmap64(void*, size_t, int, int, int, off_t);
     static if (__USE_FILE_OFFSET64)
         alias mmap = mmap64;
     else
         void* mmap(void*, size_t, int, int, int, off_t);
     int munmap(void*, size_t);
 }

probably does something like expose the mmap64 symbol (no idea what this code means).
maybe __USE_LARGEFILE64 has to be unset for it?

Yes those mail footers are obnoxious and incorrect and should be
yeeted into the sun, but at this point I don't think it helps anyone
bringing it up every time one appears. And the folks whose mails
include them usually have no control over it; it's forced on them
either by policy or technical measures of their mail systems. :(

Well, it's a bug that they're poking at glibc-internal macros (and
possibly defining these themselves?) rather than performing a
configure test. Especially since they apparently hardcoded as
CRuntime_Musl profile with wrong information about musl...

Assuming they don't want to fix the hard-coding, the above should just
be (and should always have been):

else version (CRuntime_Musl)
{
    void* mmap(void*, size_t, int, int, int, off_t);
    int munmap(void*, size_t);
}

with no mention of mmap64 or glibc macros.

Anyone up for sending a bug report and patch to gcc (or perhaps dmd
upstream)?

In any case, unless you're using the D language, this entire problem
can be avoided by just not enabling it in --enable-languages.
