OS X: Symbols not found about fastani HOT 8 CLOSED

@bede I didn't try the instructions. I abandoned running it on OS X and I'm just running it in Linux. Everything there is working fine.

Are you using Clang for C++ compilation? Also, did you install libomp via brew as mentioned in the install instructions?

from fastani.

Thanks Chirag. I am using Clang, but was attempting to run the OS X binary release rather than building from source.

Yes libomp is also installed, but I don't know much about dylibs on OS X, so am likely doing something silly…

from fastani.

Can you start the installation process from source in a different directory? Shouldn't take long if you already have Clang and libomp.

Right, I'd figured out the additonal Darwin CXXFLAGS needed to Makefile.in and forked the repo in order to PR, only to see you'd already commited the same change to master since the last release 😅

ifeq ($(UNAME_S),Darwin)  #macOS clang
	CXXFLAGS += -mmacosx-version-min=10.7 -stdlib=libc++ -Xpreprocessor -fopenmp -lomp

For me (OS 10.12.6) the process was therefore

$ ./bootstrap.sh
$ ./configure --with-gsl=/usr/local/Cellar/gsl/2.5
$ make

Perhaps you could tag a new binary and/or source release that works for Mac users : )

I got this similar error with macOS 10.13.6 trying to use fastani-OSX64-v1.1.tar.gz
So the dependency-free binary for macOS does not appear to work. It would be really cool if it did.

Yeah, no release has been tagged since I opened this, and the OS X bin is still broken. Do my instructions work for you @rotheconrad ? You'll need a clone or tarball of master.

from fastani.

I've marked a new release (1.2) today, sorry for the delay :)
The pre-built binary is provided for linux users; mac users are recommended to build from source.
