Symbol not found: _exc_server

[patrice....@yahoo.fr]

Hello,

Thanks for this interesting project !

I want to create a multi-platform binary for a project I've done at work. My primary OS is GNU/LINUX. I've used WINE to create a WIN32 binary. I want to use DARLING to do the same for the OS X side.

So I'am trying to run 'Steel Bank Common Lisp' http://www.sbcl.org/platform-table.html with dyld. That does not work and I 've got this error message :

      dyld: Cannot execute binary file: Symbol not found: _exc_server

I've compiled DARLING via GENTOO ebuild (app-emulation/darling-9999.ebuild)

Thanks for your help :) !

attached is
  - what I get enabling DYLD_DEBUG=+debug  DYLD_IGN_MISSING_SYMS=1
  - some info on my system

Cheers,
Patrice

Hello,

even though SBCL seems to be a multiplatform app, it uses a set of APIs not implemented in Darling.

That being said, it seems to ignore these problems when DYLD_IGN_MISSING_SYMS is used.
I can see a crash, but it's only happening when the app is unloading. I haven't examined the true cause yet.
