Andrew, The file "config.log" contained this: | #include <sys/ioctl.h> configure:18821: result: no configure:18821: checking sys/ioctl.h presence configure:18821: gcc -std=gnu99 -E conftest.c configure:18821: $? = 0 configure:18821: result: yes configure:18821: WARNING: sys/ioctl.h: present but cannot be compiled configure:18821: WARNING: sys/ioctl.h: check for missing prerequisite headers? configure:18821: WARNING: sys/ioctl.h: see the Autoconf documentation configure:18821: WARNING: sys/ioctl.h: section "Present But Cannot Be Compiled" configure:18821: WARNING: sys/ioctl.h: proceeding with the compiler's result configure:18821: checking for sys/ioctl.h configure:18821: result: no configure:18828: error: "Missing necessary header-file" Needless to say, this is odd. Also, I don't have any problems compiling the LDM package on our SunOS 5.10 system. I noticed that you invoked the configure(1)-script with the argument "CFLAGS=-I/usr/include". It would be better to include that particular option in the CPPFLAGS variable. Would you please try again with the command-line "./configure --enable-logging=local0 --disable-max-size CC=gcc CPPFLAGS=-I/usr/include".
