Hello,
my name is Dominik Winter and I'm currently writing my bachelor's thesis
about deploying a HTTP relay with the rumpkernel.
The HTTP relay that I must use is written in perl and therefore I need to
get the perl interpreter running inside the rumpkernel.
Unluckily there is not even one appraoch in the internet for perl.
What I tried so far is the following:
1. Build the rumprun toolchain on a x86_64 vanilla netbsd
2. Get the perl source code
3. Run the perl specific Configure with the normal cc (if specifying the
x86_64-rumprun-netbsd-gcc the script breaks because of compiler tests of
try.c)
4. Patching the Makefile by changing CC= x86_64-rumprun-netbsd-gcc and
adding LDFLAGS= -static -sttaic-libgcc -L/root/rumprun/lib/ and
CPPFLAGS=-I/root/rumprun/include
5. When running make this is the gcc command that gets executed:
x86_64-rumprun-netbsd-gcc -o perl -static -static-libgcc

lib/auto/Encode/TW/TW.a lib/auto/Encode/Unicode/Unicode.a libperl.a `cat
ext.libs` -lpthread -lm -lcrypt -lutil -lc -lposix
And it will always break with the error: ld: cannot find -lposix
If I remove -lposix from the gcc command I get errors like:
miniperl: In function `Perl_pp_syscall':
undefined reference to `syscall'
....
I can find the libposix.a on my netbsd host from where I try to build, but
if I add -L/usr/lib/ to the gcc command it also breaks with multiple
definition errors.
Any help would be greatly appreciated!!
Kind regards and thank you
Dominik
