Hello,

I’m getting the following error in http error log:

Anyone ideas ?

Thanks,

Are the gd libraries correctly installed?
does the map work in nagios?

[nagios@nagios project]$/usr/bin/gdlib-config --all
GD library 2.0.33
includedir: /usr/include
cflags: -I/usr/include
ldflags: -L/usr/lib
libs: -lXpm -lX11 -ljpeg -lfontconfig -lfreetype -lpng12 -lz -lm
libdir: /usr/lib
features: GD_XPM GD_JPEG GD_FONTCONFIG GD_FREETYPE GD_PNG GD_GIF

[nagios@nagios project]$rpm -qav|grep gd
sysklogd-1.4.1-44.el5
php-gd-5.1.6-20.el5
gdbm-1.8.0-26.2.1
graphviz-gd-2.22.2-1.el5
gd-2.0.33-9.4.el5_1.1
gd-devel-2.0.33-9.4.el5_1.1

It looks like that the gd libraries are correctly installed.
The map also don’t work, same http error

What do you mean with switching off and on ?

What does the nagios configure output say in regards to GD?

No ideas, but it’s worth trying to upgrade to 3.0.6 even if the changelog doesn’t report anything for the GD libs or map…

Solved, the issue had to do with the fact that the gd libs were installed as rpm and as source.
I removed the source libs
libgd.a
libgd.so
gd.h

Compiled Nagios again and that did the trick.

Luca, thanks for you input.

Happy it’s fixed, thanks to you for sharing the problem and solution :slight_smile:
