I'll just mention too previous related bug reports:

Those 2 look like a different issue.

Perhaps those are different issue, but I'll explain why I think they are related:

1. by default, "dmd" creates dynamic executables.

2. if we run "dmd -v", we see the "gcc" command line that DMD uses.

In this bug, and with the mention thread, the person took the output from dmd, and added (manually) "-static" - directly to the gcc command line.

3. In the other two mention threads, the person used "-L-static" to tell DMD to pass "-static" to the linker. But the way DMD passes the parameter to the linker is by adding "-Xlinker -static" - which has slightly different effect (and different error message).

So,
while it could be that the error messages are different (and perhaps the root
cause is different),
These are related bugs (IMHO) - they both try to compile static binaries on
linux.
At least it's worth knowing about those two.


Example:

$ cat hello.d
import std.stdio;
void main()
{
writeln("hello world");
}

# Compile
$ dmd -ofhello.o -c hello.d

# Link, dynamically, and see the default "gcc" command line
$ dmd -v -ofhello hello.o
binary    dmd
version   v2.064
gcc hello.o -o hello -m64 -L/usr/lib64/ -l:libphobos2.a -lpthread -lm -lrt

##
## This bug: try to compile it statically, directly with gcc.
##

## This bug: directly add "-static" to gcc:
$ gcc hello.o -o hello -m64 -L//usr/lib64/ -l:libphobos2.a -lpthread -lm -lrt
-static
/usr/lib64/libphobos2.a(sections_linux_4ce_420.o): In function
`_D2rt14sections_linux11getTLSRangeFmmZAv':
src/rt/sections_linux.d:(.text._D2rt14sections_linux11getTLSRangeFmmZAv+0x38):
undefined reference to `__tls_get_addr'
collect2: error: ld returned 1 exit status

##
## The other two bugs: add "-static" through "dmd"
##
$ dmd -L-static -v -ofhello hello.o
binary    dmd
version   v2.064
gcc hello.o -o hello -m64 -Xlinker -static -L/usr/lib64 -l:libphobos2.a
-lpthread -lm -lrt
.../x86_64-unknown-linux-gnu/bin/ld: cannot find -lgcc_s
.../x86_64-unknown-linux-gnu/bin/ld: cannot find -lgcc_s
