how to build gdbserver as a static binary ?

[William Tambe]

Is it possible to build gdbserver as a static binary ?

Using --enable-static --with-static-standard-libraries has not helped.

I don't know the answer.  I guess you could check to see if
--with-static-standard-libraries even affects gdbserver.

Also, I wonder if it's even possible.  Isn't there some problem with
statically linked programs using dlopen?  (I only vaguely recall
something like this.)  Anyway, this matters because gdbserver has to
dlopen libthread_db.

$ /path/to/configure --disable-bfd --disable-binutils --disable-gas \
	--disable-gdb --disable-gold --disable-gprof --disable-ld \
	--disable-libctf --disable-libdecnumber --disable-opcodes \
	--disable-readline --disable-sim LDFLAGS=-static
$ make

or suchlike.

 ISTM `--with-static-standard-libraries' does affect `gdbserver', but that 
option only causes static libgcc and libstdc++ to be pulled anyway rather 
than building a proper static executable.

 It shouldn't be an issue with glibc on Linux systems nowadays, though 
when running such a `gdbserver' executable you may have to make sure the 
release number of shared libthread_db used matches the release number of 
glibc `gdbserver' has been statically linked with.

 I can't speak of other hosts.
