I apologize for any repeated answers.
As of now, I've simply been trying to compile the tests within buildrump.sh
like: buildrump.sh/tests/fstest
If I'm not mistaken, to accomplish this, I should only need to provide the
linker with the necessary rump libraries?
My attempts so far have amounted to compiling with -lrumpfs_kernfs
-lrumpvfs -lrump -lrumpuser.
Which compiles and executes after setting my LD_LIBRARY_PATH. However it
does not return successfully and ends up executing the first die()
statement in the src.
./buildrump.sh test should build and run those tests. Is that command
successful? If yes, do what it does. If no, file an issue report.
My question is: in order to make an application run through rump kernels
within a posix environment, do I need to continue looking for the right
libraries to add, or should I be focusing my attention towards either the
rumprun or rumpctrl repositories?
I'm not using rumpctrl because I want to stay away from running a server
for my end goal and I don't need to modify or test the drivers quite yet.
I'm not using rumprun because it appears it is only for hardware and xen
platforms yet this repository seems to do exactly what I want as far as
creating an application through rump.
As a note, I'm doing all this within linux.
A rump kernel is a kernel (and a rump one at that). A rump kernel does
not mandate that it is used by a POSIX layer. For example, one might
use the kernel drivers provided by buildrump.sh in a microkernel. Of
course, that use does not happen automatically. You can use rump
kernels from even from POSIX applications in many ways. For example,
buildrump.sh/tests run programs on the host, but uses some functionality
from rump kernels in a library fashion. That type of usage is,
LD_PRELOAD/hijacking notwithstanding, explicitly coded into the
application. If you want to run the application entirely on top of a
rump kernel with everything implicitly serviced through the rump kernel,
you are looking for unikernels.
