Thanks for your insight, arcke.

I found this useful post on memory ordering:

Quote

    memory_order_acquire: guarantees that subsequent loads are not moved before the current load or any preceding loads.
    memory_order_release: preceding stores are not moved past the current store or any subsequent stores.
    memory_order_acq_rel: combines the two previous guarantees.
    memory_order_consume: potentially weaker form of memory_order_acquire that enforces ordering of the current load before other operations that are data-dependent on it (for instance, when a load of a pointer is marked memory_order_consume, subsequent operations that dereference this pointer won’t be moved before it (yes, even that is not guaranteed on all platforms!).
    memory_order_relaxed: all reorderings are okay.

Based on this, I decided to go with memory_order_acquire.  After changing the memory order model, I successfully compiled Keyhotee with Boost 1.55 on Arch Linux.

For installing Keyhotee, you can check out my current working PKGBUILD.

Now Keyhotee crashes after I enter my desired Keyhotee ID, but that's a separate issue.

I managed to find out how to tell cmake to install to $HOME, and I am having the same issue you are saying. Is this a new issue or are you referring to an issue already reported on git. I cant seem to find it.

Ah, I was not clear.  I have not yet reported this issue on git.  I am preparing to be away from my keyboard 12/14-12/21, so I will be unavailable to test any possible solutions for a while.  If you could report it in the mean time, I would greatly appreciate it.

The console log reports this after crashing upon clicking "Finish" on the Create Keyhotee ID dialog box:

Code: [Select]

3333816ms stretch_s  keychain.cpp:27               operator()           ] .
Illegal instruction (core dumped)

I tried to compile Keyhotee this morning, and compiling failed with errors:

I am fairly certain that this commit is to blame.

Have we found a solution to building Keyhotee on Arch Linux with boost library 1.55 installed?

Code: [Select]

[/pre]

I wish I had a solution since I have also unsuccessfully tried to compile Keyhotee with boost 1.55 on Arch Linux.

Based on my research (or the best I can do as a non-coder), the file boost/atomic/detail/platform.hpp in boost 1.55 includes a file, boost/atomic/detail/gcc-atomic.hpp, that does not exist in boost 1.54.

Possibly relevant Git revision
Possibly relevant SVN changeset

I am hopeful that this will be resolved by the time that Keyhotee goes live New Year's Eve since having a Keyhotee Founder ID is not particularly useful to me if I cannot simply compile and run Keyhotee on my preferred OS.

I added this issue on git:
