[rrd-users] RRDTool as a server in Solaris

[Steve Shipway]

I think 'isnan' is a symbol in the libm maths library; the error message you give seems to indicate that librrd is loading, but is trying to access a symbol that doesnt exist.

Checking the current version on RHEL5, I see that isnan is now a #define rather than a library function.  This would seem to indicate that your rrdtool was compiled using an older version of the maths library that expects isnan to be a symbol in libm.so rather than an inline compile.

I'd suggest you recompile rrdtool using the current libraries on the system you have; or, install the older version of libm in parallel, if possible.  The package you're installing seem to have been built with a too-old C compiler.

Hi Steve,

I tried. However, I've been trying truss and ldd to check if the necessary libraries exists but I didn't get any clue.

I've found that library but in the end it says:
/opt/csw/lib/i386/librrd.so.4: symbol isnan: referenced symbol not found

which from my point of view could mean that there is a version mismatch.

There's something strange I've seen and it's that I have two different directory branches with similar libraries:

/opt/csw/lib and /export/home/opt/csw/lib most of the required libraries seem to be in /export/home/opt/csw/lib (as you mention maybe that directory is not in library classpath.
