Hi Daniel,

The accelerator was changed in a way that requires some newer cmake features, but the cmake minimum required version (https://github.com/seL4/camkes-tool/blob/master/tools/accelerator/CMakeLists.txt#L15) was not updated resulting in this non-intuitive failure. The minimal cmake version is now 3.7.2 and I will update the accelerator accordingly, but you should make sure your version of cmake is at least that.

Sorry to bother again. Just want to confirm the last working version for me (built on a Ubuntu 16.04 virtual machine) is camkes-arm-vm-manifest d648f10. I do not know if it is because some of the tools I have is old or something. I just found repo support local-manifest. So check out the old commit and copied the default.xml to another file in .repo and use command “repo sync -m local-manifest.xml”.

For other version it stops at building camkes-accelerator:

I’m afraid that the new update in default.xml in camkes-arm-vm-manifest repository may cause the problem. I could not get the old commit back, the “repo sync” seems always do a git pull before fetching… Does anyone know how to make repo download based on old manifest.xml?

I saw something similar with Camkes-arm-vm-manifest repository after I sync. Will do more test make sure it is not a issue with configuration.

Hi Thad,

Can you please provide steps to reproduce this.

Good day. I am getting hung up compiling the CAmkES compiles. I'm getting
following error which I believe is because the version.h.d does not exist.
Where is the version set?

thx
