Issue https://github.com/unikraft/app-elfloader/pull/32

Reproduce an error

Inside the app-elfloader directory, run the generate.py script ./scripts/generate.py.

Find scripts in the scripts/run/ directory named qemu-x86_64-9pfs-http_server.sh.

Build the elfloader by running ./scripts/build/make-qemu-x86_64-9pfs.sh, showed the following error-

[chococandy@fedora app-elfloader]$ ./scripts/build/make-qemu-x86_64-9pfs.sh
make[1]: Entering directory '/home/chococandy/unikraft-devel/app-elfloader'
make[1]: *** /home/chococandy/unikraft-devel/app-elfloader/workdir/unikraft: No such file or directory.  Stop.

Then, running ./scripts/run/qemu-x86_64-9pfs-http_server.sh showed the error below-

[chococandy@fedora app-elfloader]$ ./scripts/run/qemu-x86_64-9pfs-http_server.sh

@chococandy63 , you have to clone unikraft and support libraries, as advised in the "Set Up" section in README.md. Please see if that works and then we will close this issue,

@razvand I am using Fedora Virtual Machine, ./scripts/build/make-qemu-x86_64-9pfs.sh was showing errors related to yacc but after running export YACC=/usr/bin/bison it worked successfully. But, this command ./scripts/run/qemu-x86_64-9pfs-http_server.sh is still showing errors- it says machine not found and then shows this

console
SeaBIOS (version 1.16.2-1.fc38)

iPXE (https://ipxe.org) 00:03.0 CA00 PCI2.10 PnP PMM+02FCBFD0+02F0BFD0 CA00

Booting from ROM..[    0.000000] CRIT: [libkvmplat] <paging.c @  541> Assertion failure: ukarch_paddr_range_isvalid(paddr, paddr + len)

What could be the reason? It seems like something related to kvm.

Btw, the fedora yacc issue is really creating problem so should I create an issue for fixing it on Unikraft repo? Could you please guide me on that.

[razvand]

Yes, please create an issue regarding yacc.

Yes, create an issue related to the machine build.

Close this issue, as it's not an actual problem.
