Is it possible to build Snowman without IDA?

[Morten Friesgaard]

I'm was just wondering, is it possible to build snowman without IDA? I see that there is a standalone for windows, and I want to build a standalone for OS X.

[yegord]

Yes, there have been multiple reports about successes.
I guess, just following the build instructions will do.

[Morten Friesgaard]

Oh, I read the warning as an error. I was missing Boost. However, I have a linker issue with QT. I tried with both v4 and v5 without luck. Any hints to make it work on mac?

[yegord]

So, what is the error?

Did you build Qt in QT namespace?

[Morten Friesgaard]

I tried to search for nocode, mac os x, x86_64, and QT. I'm just stuck.
Maybe I need a specific version of nocode?

[Morten Friesgaard]

You are referring to bullet 3 under "Notes on Building IDA Plug-In" (a bit confusing), then no. But I guess I have to download QT manually instead of installing it with homebrew?

[yegord]

It seems, you have specified -D QT_NAMESPACE=QT when configuring Snowman, while having Qt built not in QT namespace (by default it is not built in a namespace).
Just configure using cmake from scratch and do not specify -D QT_NAMESPACE=QT.
This should fix your problem.

[Morten Friesgaard]

Same error, will have to look at it tomorrow. Thanks for the fast reply!

[yegord]

You probably did not reconfigure from scratch.
CMake tends to cache configuration parameters.
Removing the build directory completely is the easiest way to make sure QT_NAMESPACE=QT is not cached anywhere.

[Morten Friesgaard]

Nice, thank you!
I reset the repository and started over without QT_NAMESPACE=QT and now it works!
