Projections fail using the Mac Binaries:
mono EventStore.SingleNode.exe --db ./db --log ./logs --run-projections=all
I just get the following error message:
The projection subsystem failed to load a libjs1.so/js1.dll/… or one of its dependencies. The original error message is: js1
$LD_LIBRARY_PATH = /usr/lib:/Documents/DevProjects/EventStore-MonoMac-v3.0.0rc2 (the location of event store)
It works fine on Windows and on Ubuntu
Thanks
It’s DYLD_LIBRARY_PATH on the mac, the next RC has mono statically linked and doesn’t have this issue as the install names of the dylibs and on the image are ./
James
Sorry James, DYLD_LIBRARY_PATH is set to exactly the same but still get the issue? I tried reading the other posts but I couldn’t find an answer… or will it just not work?
I’ll take a look in a couple of minutes, it should work with that. What do you get from: otool -L libjs1.dylib ?
James
echo $DYLD_LIBRARY_PATH /usr/lib:/Users/davidespley/Documents/DevProjects/EventStore-MonoMac-v3.0.0rc2
libjs1.dylib:
libjs1.dylib (compatibility version 0.0.0, current version 0.0.0)
libv8.dylib (compatibility version 0.0.0, current version 0.0.0)
/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)
Much appreciate the help
Are you running 32 bit mono?
Not intentionally… version is
TLS: normal
SIGSEGV: altstack
Notification: kqueue
Architecture: x86
Disabled: none
Misc: softdebug
LLVM: yes(3.4svn-mono-(no/e656cac)
GC: sgen
So looks like yes
If you installed it from Xamarin’s packages it will be 32 bit - inexplicably they don’t distribute 64 bit versions for OS X.
Unfortunately libjs1 (which is what you’ll need to load for JavaScript projections) is only built for 64 bit architectures, and this is the reason you can’t load it (you actually don’t need any LD_LIBRARY_PATH or DYLD_LIBRARY_PATH set on OS X as the install
names of the dylibs refer to the current directory).
You have a couple of options:
Use ES without projections
Build 64 bit Mono from source (it’s actually fairly easy) - I’d recommend installing in something like /opt/mono- and then creating a symbolic link from /opt/mono so you don’t have
to keep changing paths
Use this build which has 64 bit mono statically linked: https://www.dropbox.com/s/5kez7p6cw3e8hud/EventStore-Mac-v2.99.99.tar.gz

Cheers James, thanks for the swift response… will build mono now!
If I were you I’d use the statically linked version - that’s how it will present from the next RC on both Linux and OS X (though separate packages for each) 
However, building Mono 64 bit may be useful for other stuff as well.
Thanks again James, will give that a try first and then try to build mono…
For what it’s worth, 32-bit mono on OSX is explained here (http://tirania.org/monomac//archive/2013/Nov.html), though it’s getting on 7 months since that update… Sure would be nice to move to 64 bits in the public builds.
As I understand it this is more to do with the bindings to OSX native APIs rather than the runtime and BCL - the framework has been fine compiled as 64 bit for a long time on OSX (though may explain why there are no packages).
James
Totally – but I assume since Xamarin is mostly in the Apple & Android app-building business, I assume the wait to get all the packages working the way they want explains why the off-the-shelf build is still 32 bits. It’d be nice if they gave us precompiled 64-bit framework to save the trouble of building them. Though as you say… building them isn’t too hard.
I know it’s been a month, but I’ve (accidentally) found that the easiest way to get mono 64bit that runs ES on a mac is to follow the install instructions for getting edge-js running on a mac here: https://github.com/tjanczuk/edge#building-on-osx
Basically use homebrew and run: brew install https://raw.githubusercontent.com/tjanczuk/edge/master/tools/mono64.rb
Installs links into /usr/local/bin that can easily be removed with the standard brew commands.
Cheers.
If you just want to build from source yourself, the steps are:
install automake, autoconf, libtool etc
install Mono 32 bit distro
git clone https://github.com/mono/mono
git checkout mono-3.4.0.204
./autogen.sh --prefix=/opt/mono-3.4.0.204 --disable-nls
make
make install
uninstall Mono 32 bit distro
ln -s /opt/mono-3.4.0.204 /opt/mono
export PATH = /opt/mono:$PATH
It’s a lot of faffing about - the statically linked binaries will be much easier to use. They’ve just gone out to commercial customers as RC4, so an OSS one will likely follow soon.
Cheers,
James
