             Bug #: 13679
           Summary: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer
                    equality
           Product: glibc
           Version: 2.15
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: burek021@gmail.com
    Classification: Unclassified


Hi,

I used the latest git for the source code for glibc (2.15.90) and I used this
configure line:

~/glibc-build # ../glibc/configure --enable-static --disable-shared
--prefix=/usr/local/glibc-static

(it complained about not recognizing ld, because I'm on debian and using
binutils-gold, so I downloaded/compiled gnu binutils and solved that error)

after a successful configure, I ran 'make' and it compiled a lot of stuff and
finally gave me this error:

...

-Wl,-z,relro -Wl,--hash-style=both /root/git/glibc-build/csu/crt1.o

executable; recompile with -fPIE and relink with -pie

make[1]: *** [iconv/others] Error 2
make[1]: Leaving directory `/root/git/glibc'
make: *** [all] Error 2
glibc-build # 


I'm not sure is it a bug or I'm doing something wrong here. I need to build the
static glibc so that I could build static ffmpeg with it, that's my goal.

Anyway, if this is not a bug, I really apologize.

FWIW,

1. Glibc developers consider fully-static linking a "step child", and your bug
will likely be ignored ...

2. For your stated goal of "static ffmpeg", you don't need to build a
--disable-shared glibc.

The regular build already supplies libc.a. Just do "gcc -static ... -o ffmpeg"
and be done with it.

--disable-shared may be useful for porting purpose.
