Current Build of MWorks

Support
1

Hi Chris,

We just did a new install of El Cap on a MacPro (2010). After install Xcode and disabling SIP crap, we downloaded the latest version of MWorks from

https://s3.amazonaws.com/mworks-downloads/release/MWorks-0.6.dmg

Everything looked good.

then we tried to clone the current githib repo, but had some trouble compiling the core (permission errors). After fixing that, we finally got he core to build successfully. The problem is that as soon as we launch the server (stock from the DMG), it crashes with the following error:

Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Application Specific Information:
terminating with uncaught exception of type mw::SimpleException: trying to access singleton instance before it is registered
abort() called

From the crashed thread:

Any clues? We downloaded an older commit (from the start of the 0.7 dev) and all is fine.

There are no custom core plugin builds (unlike Evan’s issue from two days ago).

Hi Romesh,

There are no custom core plugin builds (unlike Evan’s issue from two days ago).

It’s the same basic issue: The installed version of MWorksCore (the one you compiled yourself) is different than the one the apps and plugins were built against (the 0.6 release), and there are binary incompatibilities between the two versions that are leading to crashes.

I really need to write a knowledge base article on how to compile all of MWorks from scratch, as that’s the only way to ensure binary compatibility after making changes to MWorksCore. However, in the meantime, you stand a decent chance of things working if you start with the commit from the 0.6 tag (c1863e7), rather than the current HEAD commit.
