trouble building the browndeer examples

[afh]

When I try to build the hello_stdcl example in /Work/examples/parallella/hello_stdcl/ I get the following error :

[2577] clmesg ERROR: clcc.c(718): clcc: clld returned non-zero exit status 11
=======================================================================================
I get the same error when I try to build bdt_nbody_32.I'm using the browndeer COPRTHR lib that came with the board...
What could be the cause of this ?

I had the same issue I believe. For me, there was a problem with the `clld` program, just running clld would immediately return a segmentation fault. I fixed it by rebuilding the libraries from their source.

The sources are here:
The instructions are here (page 4):

Arriving late to the discussion, but I can confirm that the pre-installed package seems to have problem.

Using a clean platform with latest image I removed entirely /usr/local/browndeer and rebuilt the stable-1.6 branch and things worked fine.

./configure --enable-epiphany --with-libevent=/usr

got me over this problem.
