[panda-users] Issues with building QEMU

Fri Jan 23 11:19:13 EST 2015

Hi Evan.  If you are trying to build most current, you will need protocol buffers (protoc and protoc-c).  It looks like you might not have them?  What happens when you type one of these two commands at the command line?

protoc

protoc-c

Subject: [panda-users] Issues with building QEMU

Hey all,

My name is Evan and I'm a first-time PANDA user.

I was attempting to build the source code as stated here: https://github.com/moyix/panda/blob/master/docs/compile.md

I followed the instructions to the 'T', however I was unable to build QEMU.

I have made sure that I have the most recent version PANDA from here https://github.com/moyix/panda

My machine's specifications are as follows:

$ uname -a

Linux fun 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1 x86_64 GNU/Linux

The error occurs on the last step ("Building the QEMU Part") when I attempt to run `$ sh ./build.sh`

I will not post the whole error (because it's way too long), but here are bits and pieces of it that I believe are important:

Any ideas as to what the problem is?

It seems as though someone has already seen part this problem (https://github.com/moyix/panda/issues/19) but I wasn't quite sure if these were the same or related to each other.

Thanks,

Evan
