Howto install Qira on ubuntu 20.04

[smurfd]

This is done on a fresh install of ubuntu 20.04 with installed git.
grab these :
qira-qemu.txt
qira.txt

git clone https://github.com/geohot/qira.git
cd qira
patch -p1 < ../qira.txt

install.sh will end in error : util/memfd.c:43:12: error: static declaration of ‘memfd_create’ follows non-static declaration

cd tracers/qemu/qemu
patch -p1 < ../../../../qira-qemu.txt

cd ../../..
./install.sh
Booom :)

Can you please help me, I am n00b(

[smurfd]

weird, try to in the qira folder:
mv venv venv1
then rerun the install.sh

if that does not work, im not sure ...maby you had installed pip2 already!?

[Wgmlgz]

Yes, a have pip2 installed (I comment pip2 installation lines), but now I am getting another error:

[smurfd]

from my 1st post :

install.sh will end in error : util/memfd.c:43:12: error: static declaration of ‘memfd_create’ follows non-static declaration

cd tracers/qemu/qemu
patch -p1 < ../../../../qira-qemu.txt

cd ../../..
./install.sh

[Wgmlgz]

I ended up just reinstalling my ubuntu vm and your patches are working! By the way, can you please make patch for kali?

[smurfd]

same works for kali linux also, u just need to grab these and install them before ... since they seem to have screwed up something about their python2 install.
http://ftp.us.debian.org/debian/pool/main/p/python-scandir/python-scandir_1.9.0-2_amd64.deb
http://ftp.us.debian.org/debian/pool/main/p/python-filelock/python-filelock_3.0.10-1_all.deb

[Wgmlgz]

Man, that's works for kali! Thanks you a lot!

[smurfd]

These will not force python2, but use python3 only

Grab and save to a folder. had to update some stuff in the requirements.txt

qira-py39.txt
qira-qemu-py39.txt

Then :

git clone https://github.com/geohot/qira
cd qira/tracers/qemu
git clone https://github.com/geohot/qemu.git --depth 1 --branch qira
cd qemu
patch -p1 < ../../../../qira-qemu-py39.patch
cd ../../..
patch -p1 < ../qira-py39.patch
./install.sh

OBVIOUSLY there might be some subtleties that im missing or have broken. use at own risk, same ofcourse goes for previously pasted patches...

Sidenote:
Also tried to build against qemu git main. the trick to building that was to remove the --cpu=unknown and rearrange the symlinks in tracers/qemu to point to point like : qira-aarch64 -> qemu/build/aarch64-linux-user/qemu-aarch64

Something with the webserver/client/update part did not like this however :/
pretty sure it is some python2 to python3 junk that breakts things.

[hopinheimer]

Apparently python-pip has been removed from the repositories for Ubuntu 20.04 and according to the install.sh script python-pip is being used may be that's the reason
Ubuntu 20.04

Thank you @smurfd your patch works on my Ubuntu 20.04 VM

[a1eaiactaest]

works on Ubuntu 21.04 as well.

I created a fork with all patches applied. if someone doesn't want to manually patch qira and qemu just clone a1eaiactaest/qira and normally run ./install.sh. i think everything should be fine.
