[rrd-developers] rrdtool-1.3.99909060808 configure error

[Barrie]

Hi Tobi,


The configure script is using the Solaris ctime_r test which has three 
parameters. The configure script needs to #include "src/win32comp.c" to 
access win32 ctime_r. The win32 ctime_r only has 2 parameters.
I'm sure it is all configurable in the configure.ac and the 
m4/acinclude.m4 scripts, but my skills with m4 and autoconf are worse 
than my C skills. :-)   Happy to learn. But I'm not sure where to start.

I have modified the configure script to work around this problem and the 
script continued until it failed with problems with dependencies. 
Working on that now.

A question. The configure script has an option to cache.  Is this 
possible ?  The  configure options  show  a  [DISABLED] against the 
--cache-file=FILE option. Does this mean the option is not available for 
the rrdtool configure script.

I have tried the -C and --config-cache options.

When the configure script runs I get the following.

configure: loading cache config.cache

The config.cache file is created, but it is zero length. It would be 
good to use as it takes so long to run the configure script through all 
the options that have passed.

Cheers, Barrie
