Description tropikhajma 2009-11-03 01:25:13 UTC
Version:           4.3.73 (using Devel)
Compiler:          Sun Studio 12 U1 
OS:                Solaris
Installed from:    Compiled sources

build on OpenSolaris b125 with SunStudio 12 U1 fails with:
...
"/export/home/hajma/packages/BUILD/kdebase-workspace-4.3.73svn1040395/ksysguard/gui/SensorDisplayLib/SignalPlotter.cc", line 143: Error: The function "isinf" must have a prototype.

4 Error(s) and 1 Warning(s) detected.

from what I gathered searching the web, isinf is not really portable across platforms.

patch

actually the mysql link is wrong as well, 'finity' is not part of the C++standard either. Here's my patch, practically taken from http://bytes.com/topic/c/answers/588254-how-check-double-inf-nan
Comment 2 John Tapsell 2009-11-03 02:42:55 UTC
Doesn't your my_isinf function return the exact opposite?   It returns true if the number is finite.
Comment 3 tropikhajma 2009-11-03 10:19:39 UTC
damn, right, too late in the night, I only cared if it compiles. sorry

better patch

This one should be better. What would be the best way to verify the code works as expected? where in ksysguard should I go? TIA

The graphs should be drawn in the second tab.  Also the unit tests should pass:

cd build/kdebase/workspace/ksysguard/gui/tests  (or wherever your
build directory is)
make buildtests
make tests

They should all pass.
Comment 6 groot 2009-12-27 00:23:46 UTC
On Solaris, I think the correct approach is through ieeefp -- which is done in several other places in the KDE sources:

     #include <ieeefp.h>
     int finite(double dsrc);
Comment 7 tropikhajma 2010-03-23 01:07:38 UTC
perhaps something like

#if defined(HAVE_IEEEFP_H) && defined(__SUNPRO_CC)
#include <ieeefp.h>                               
#define isinf !finite                             
#endif

?

with 
check_include_files(ieeefp.h HAVE_IEEEFP_H)
in some 
CMakeLists.txt
?

tropikhamjma, any chance of a finished patch that I can commit?

Can you reproduce this issue with current version of ksysguard?
