Unable to load plugin

You should see some output like the following when run from the terminal:

$ /Applications/Hopper\ Disassembler\ v4.app/Contents/MacOS/Hopper\ Disassembler\ v4

You probably also want to try the reimpl branch, where you can choose between two disassembler engines, one with limited instruction support (MIPS32) but better address handling, the other is based on capstone but the address handling is a little messed up :/

Just tried this in the reimpl branch and I'm seeing this:
ERROR: Cannot load /Users/joe/Library/Application Support/Hopper/PlugIns/v4/CPUs/MIPSCPU.hopperCPU, plugin makes use of external function(s), and may be too slow for a CPU plugin. Also, make sure that plugin is compiled for OS X 10.9, or higher.

This is interesting, when building with xcodebuild I'm getting the same error. When building from Xcode (8.3.2) it works fine. I'm not sure why though.

I'm seeing similar behavior. I just tried building from within XCode itself. It looks like it's trying to load it but now I'm seeing this error:

2017-04-26 14:18:56.080 Hopper Disassembler v4[86224:2322157] Missing implementation of method "cpuContextClass" in "MIPSCPU" to conform protocol "CPUDefinition"
2017-04-26 14:18:56.080 Hopper Disassembler v4[86224:2322157]   ERROR: Class MIPSCPU does not conform to protocol CPUDefinition.

I did an upgrade this morning to hopper. Not sure if that is responsible for this error or not.

[makigumo]

Yes there was an SDK change. The reimpl branch is already updated ( 14f77fe).

[jrozner]

Cool, that worked. Thanks!

[makigumo]

That's good.

I just checked with the sample M68kCPU plugin from the SDK and it is showing the same problem.
I could narrow the problem down to the Release configuration, e.g. xcodebuild -configuration Debug is working.

Load issues were fixed in Hopper 4.2.0.
