Hi Everyone,
I have been trying to build a luajit unikernel and am following luajits
instructions on cross compiling http://luajit.org/install.html#cross . I have ;
the tool chain setup and have ran the hello world example there. Sadly, I am
unable to build luajit. I have made some attempts and have attached the output
for each of these commands. I would really appreciate any help in this matter.
There are lots of talk about building a luajit unikernel but I can’t seem to
find the process. So here it goes

Based on the suggestion “ For a minimal target OS, you may need to disable the
built-in allocator insrc/Makefile and use TARGET_SYS=Other. Don't forget to
specify the same TARGET_SYS for the install step, too.” I uncommented line 131
"XCFLAGS+= -DLUAJIT_USE_SYSMALLOC” and ran it again

After this last failed attempt I thought let me contact the pros as they have
done it right already.
To me it seems like the building of the .so and the whole ldl process is
failing. In short could I build a luajit binary without building libluajit.so ?
Thanks
