[syslog-ng] logwriter.c:241: error: LogWriterWatch hasno member named - Red Hat 5.x 32BIT

Hi,

You explicitly enabled linux capability support, but you don't have the
necessary libraries installed.

the configure script autodetects libcap and uses it if available.

I tested compilation on Debian though, so RHEL might be different. Do
you have a <sys/capability.h> file?
