Bug ID: 113081
Summary: static linking does not work
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
Trying to statically link a Hello World doesn't work:
import std.stdio;
void main()
{
writeln("Hello, World!");
}
> gdc-13 t.d -static
...
/usr/lib64/gcc/x86_64-suse-linux/13/../../../../x86_64-suse-linux/bin/ld:
/usr/lib64/gcc/x86_64-suse-linux/13/libgphobos.a(elf.o): in function
`_D3gcc8sections3elf11getTLSRangeFNbNimmZAv':
/home/abuild/rpmbuild/BUILD/gcc-13.2.1+git7813/obj-x86_64-suse-linux/x86_64-suse-linux/libphobos/libdruntime/../../../../libphobos/libdruntime/gcc/sections/elf.d:1095:(.text._D3gcc8sections3elf11getTLSRangeFNbNimmZAv+0x29):
undefined reference to `__tls_get_addr'
collect2: error: ld returned 1 exit status
that's libphobos/libdruntime/gcc/sections/elf.d:1095
void[] getTLSRange(size_t mod, size_t sz) nothrow @nogc
{
...
else
return (__tls_get_addr(&ti)-TLS_DTV_OFFSET)[0 .. sz];
}
}
not using a TLS relocation but an explicit call. A TLS relocation would
have been resolved/relaxed at static link time but an explicit call of
course prevails.
Linking the Hello World with -static-libphobos works (there is no
-static-libdruntime but libgdruntime.so.4 doesn't seem to be DT_NEEDED
on the executable?).
Maybe putting the TLS module helpers into a separate object (so not
statically linked when not needed) might help, implementing the helpers
in a way that allow static linking might be possible as well (by
using actual __tls declarations?).
