newbie-02 <newbie-02 at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #1 from newbie-02 <newbie-02 at gmx dot de> --- Sorry, withdrawn, writing here helped ( was necessary? ) to clear my head and narrow down the problem between working and not working. I had copied the library compile command from a manual, and didn't think to check the optimization level, it was missing an -O2, so the direct commands are fast again.
