I think Static executables do not have symbol _DYNAMIC

How do you configure your build?


mkdir -p out/arm && cd out/arm
../../configure --prefix=/tmp/glibc/arm --host=arm-linux-gnueabihf
--enable-static-pie --enable-hardcoded-path-in-tests
make -j 60  # good

% grep pie_supported config.log
libc_cv_pie_supported=yes
libc_cv_static_pie_supported=no

Note that sysdeps/arm/configure.ac doesn't say `AC_DEFINE(SUPPORT_STATIC_PIE)`,
so I think static-pie for sysdeps/arm is unsupported.


% cat a.c
const char *foo (void)
{
  extern const char _DYNAMIC[] __attribute__((visibility("hidden")));
  return _DYNAMIC;
}
% arm-linux-gnueabihf-gcc -fpic  -nostdlib -static-pie a.c
# good. Both -shared and -pie have .dynamic and define _DYNAMIC

I want to get statically linked sln
It is work in the gcc 7.3.0 version, but build error in the gcc 10.3.0

You cannot just define SUPPORT_STATIC_PIE when in fact support for static pie
is not existing.

Why it works in 7.3.0, but compiles error in 10.3.0?

Because gcc 7 does not know anything about static-pie.

What version of gcc are you using?

I used gcc 10.3.0 to compile the above a.c and also got the error undefined
reference to '_DYNAMIC'

--- Comment #9 from Fangrui Song <i at maskray dot me> ---
sysdeps/arm/configure.ac doesn't say `AC_DEFINE(SUPPORT_STATIC_PIE)`, so
static-pie isn't supported by the port yet. It's not correct to supply -D
SUPPORT_STATIC_PIE and pretend that it is working.

The reason could be in glibc or in binutils ld.bfd (i.e. the linker may need
some patches to properly support static pie). Then the glibc build system may
need to detect whether the linker is capable of static pie.

GCC not supporting static-pie has such an error:

    error: unrecognized option '-static-pie'
