difference between compiled and installed via rpm (zypper)
- by cherouvim
In an openSUSE 11.1 I download, compile and install ImageMagick via:
wget ftp://.../pub/graphics/ImageMagick/ImageMagick-6.7.7-0.zip
unzip ImageMagick-6.7.7-0.zip
cd ImageMagick-6.7.7-0
./configure --prefix=/usr/local/ImageMagick
make
make install
Everything works nicelly until I discover that JPG is not supported:
identify -list format | grep -i jpg
[nothing related to JPG returned]
So I reconfigure and recompile using:
./configure --prefix=/usr/local/ImageMagick --with-jpeg=yes --with-jp2=yes
make
make install
But that changes nothing.
I end up uninstalling:
make uninstall
and installing via zypper:
zypper install ImageMagick
This installed version 6.4.3 and now it does support JPG:
identify -list format | grep -i jpg
JPG* JPEG rw- Joint Photographic Experts Group JFIF format
Any idea on what is going on here? What is a possible reason that this capability of ImageMagick was not there when compiled from source but was there when installed from rpm?
Note that I don't necessarily care a lot about ImageMagick (since it now works), but generally about his kind of behaviour, becase in one way or another I've seen this happen in other ocasions as well.
