Hello again, this problem is present since 1.4.0. I know it, because I've tried every version since 1.3.8 (works), through 1.3.9 (works), 1.4.0 - 1.4.3 does not work at all with syntax error as described below. Everytime I compiled and tried the same source code and linked with the proper library version. What has changed in the API of rrd_update() in 1.4.0? I really don't understand what I'm doing wrong. Any hints/help appreciated, looking at the CHANGES file did not helped me.
