App doesn't launch

[paulirish]

After installing from Mac Store it fails to run

Running from Finder I get:

The application “Gifski.app” can’t be opened.

Running from terminal:

❯ /Applications/Gifski.app/Contents/MacOS/Gifski
dyld: Symbol not found: __TMSi
  Referenced from: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libswiftos.dylib

fish: '/Applications/Gifski.app/Conten…' terminated by signal SIGABRT (Abort)

I'm gonna try building from source now.. :p

update: i gave up building from source after this error building imagequant-sys v2.11.9: unsupported option '-fopenmp'. not ready to upgrade my clang. :/

First, congratulations. According to Google you're the first person on the web to be missing the __TMSi symbol.

From the log it seems like a bizarre incompatibility of Swift in your Xcode installation with Swift used in the app. Why did it involve Xcode at all in loading of a regular app, I have no idea.

What's your exact macOS version?

As for the build, it won't work with clang indeed. The GCC version is faster. brew install gcc should be enough to make it compile.

Yeah, that should not even happen. The Swift framework is bundled in the app.

According to iTunes Connect, there has been only one case of this crash.

The same computer that experienced this crash also got:

Symbol not found: __T0s14_VaListBuilderC15gpRegistersUsedSivpWvd + 0

I actually upgraded to High Sierra just to use gifski. :)

I'm at 10.13.3 (17D47)

My installed XCode version is 8.3.3 fwiw. brew wants me to upgrade that for gcc, so we'll know if xcode 9.2 installed fixes running the app.

Not a huge deal, guys. :) But figured I'd make the issue.

[paulirish]

yup. xcode 9.2 installed and the original problem went away. bizarre.
