Hi
I am attempting to port Solo5 to OpenBSD (Virtio only), I think i have
the kernel and test_hello compiling but when it comes to linking
test_hello i get the following error.
/home/asteen/devl/solo5/kernel/virtio/solo5.o: relocation R_X86_64_32
against 'a local symbol' can not be used when making a shared object;
recompile with -fPIC [1]
adding -fPIC to HOST_CFLAGS doesn't seem to help (HOST_CFLAGS="-fPIC
-nostdlibinc")
My changes to the configure script are located
(https://github.com/Solo5/solo5/compare/master...adamsteen:master)
Could anyone point me right direction to get this working? The full
build log is attached.
Cheers
Adam
PS I am new to c and make files, but i had to pick somewhere to start,
and solo5 has piqued my interest.
