[etherlab-users] Etherlab c-api

[Andy Rohr]

Hi

I think the Problem is that
/usr/bin/xsltproc //opt/etherlab/capi/data.c.xsl
	/home/demo/ethercat/capi/skel/my-app.xml |  > /home/demo/ethercat/capi/skel/data.c

does not write the output of xsltproc do data.c, because of the pipe. It should be:
/usr/bin/xsltproc //opt/etherlab/capi/data.c.xsl
	/home/demo/ethercat/capi/skel/my-app.xml > /home/demo/ethercat/capi/skel/data.c

I had the same problem, so I changed the Makefile and removed the pipes there. I'm on Ubuntu.

Andy
