Hi All, I am trying to build rrdtool for my verdex board without much luck. It will fail in the configuration phase complaining about IEEE math support. My setup is as vanilla as can be, pulled from svn last Friday. | checking if IEEE math works out of the box... no^M | checking if IEEE math works with the -ieee switch... no^M | checking if IEEE math works with the -qfloat=nofold switch... no^M | checking if IEEE math works with the -w -qflttrap=enable:zerodivide... no^M | checking if IEEE math works with the -mieee switch... no^M | checking if IEEE math works with the -q float=rndsngl switch... no^M | checking if IEEE math works with the -OPT:IEEE_NaN_inf=ON switch... no^M | checking if IEEE math works with the -OPT:IEEE_comparisons=ON switch... no^M | checking if IEEE math works with fpsetmask(0)... no^M | checking if IEEE math works with signal(SIGFPE,SIG_IGN)... no^M | configure: error:^M | Your Compiler does not do propper IEEE math ... Please find out how to^M | make IEEE math work with your compiler and let me know (oe...@ee...).^M | Check config.log to see what went wrong ...^M Playing around with the configuration file and adding a test using -msoft-float didn't help either. Any help would be greatly appreciated. Thanks. Bill |

Thanks for your reply Morgan. I know I'm not submitting a whole lot of info on this, but then again I don't want to bore you all with the details. The setup I have and am building against is using glibc (as opposed to uclibc) and the platform info spewed at the beginning of each build looks like : OE Build Configuration: BB_VERSION = "1.8.10" OE_REVISION = "<unknown>" TARGET_ARCH = "arm" TARGET_OS = "linux-gnueabi" MACHINE = "gumstix-custom-verdex" DISTRO = "angstrom" DISTRO_VERSION = "2007.9-test-20080902" TARGET_FPU = "soft" Could the test could be erroneous? The setup does support floating point operations. Also, if you got it to build and have a .ipk you'd like to contribute, that'd do just as well. Thanks Bill From: mo...@gm...

Hi Bill, I got rrdtool working on my gumstix cf a couple of years ago... and it's been humming along nicely ever since... I'll look at home this evening and see if there was something special I did to get it to work. MDJ |

Actually, that helps a lot. That was my plan B (thus my questions about the validity of the tests). Have you had any issues with not having proper IEEE support (according to the config tests)? Thanks. Bill From: mo...@gm... [mailto:mo...@gm...] On Behalf Of Morgan Jones Sent: Wednesday, September 03, 2008 10:08 AM To: Bill Cuffley Subject: Re: [Gumstix-users] RRDTool anyone? Actually this will probably not be a very satisfying answer... :) I checked my notes last night, but I didn't start up the development platform I used to verify. It looks like I ended up using 1.0.50 of rrdtool and (here's the unsatisfying part) I just commented out the IEEE section of config... it's been a while, but I think I looked into the test's it was doing and decided that is wasn't important... I got a binary eventually and it's been running ever since: http://www.morgman.com/mon/luminary.html I never created any packages or the like... can't be much help there sorry. I can verify more next time I boot up my main machine and look at the development code. Hope that helps, MDJ |
