Add Makefile for installing framework

[keith]

This allows you to run make install with optional environment variables
in order to build and install Chisel.framework.

Does this do anything beyond mkdir -p?

[keith]

Removed with above changes

[kastiglione]

I don't know much about Xcode's install action. Why install into a temp path and then copy from there into the true destination?

[keith]

Ah yes, nice I didn't re-think this after I made some other changes, updated

[kastiglione]

I should hopefully be able to accept this soon. In the mean time, I have a couple questions:

• Should we build a fat binary with x86 too?
• Should we code sign after copying into the destination?

I'm indifferent about the fat binary, I'm fine with being lazy and waiting for a request/need.

I don't know the ins and outs of code signing, but I hit some issues that frustrated me during development of this library. If I loaded the library from where it was originally built and code signed (within the build directory) and then later moved or copied the framework to some install location, then I would no longer be able to load the library from the installed location. The error messages were non-existent or cryptic at best, nothing that I could solve from google. Eventually I figured out that if I re-codesigned the installed library, then I wouldn't have those same loading problems. I guess what I'm asking is, is signing supposed to be post-install or can it be pre-install? Presumably pre-install, but the issues tell me that I don't really know how path comes into play with code signing verification.

This actually is building both right now, since it's a release build, ONLY_ACTIVE_ARCH is NO.

Should we code sign after copying into the destination?

Good question. The adhoc signing that's happening when I run the install now is currently working for me, but I've also only tested on the simulator. If I remove that signature I do get this for dlerror():

(char *) $3 = 0x00007fa68b400249 "dlopen(/usr/local/opt/chisel/lib/Chisel.framework/Chisel, 2): no suitable image found.  Did find:\n\t/usr/local/opt/chisel/lib/Chisel.framework/Chisel: required code signature missing for '/usr/local/opt/chisel/lib/Chisel.framework/Chisel'\n"

I should be able to merge this next week.

According to the docs, the above two should be flipped. DSTROOT=/ and INSTALL_PATH=$(PREFIX).

[kastiglione]

Should this be set to NO in the .xcodeproj? I'm fine with it here either way, but I'm wondering why not have it default to this anyway.

[keith]

I'll set it in the project since there's no reason to archive it anyways

[keith]

Addressed your feedback!

[keith]

Thanks!

You're welcome, thanks for the pull request. I'll create a pull request to add an implementation for the findinstances command some time later today.
