Re: [Seqan-dev] cmake - java version ?

Hi Bernd,

yes, we only need Java for CTD packacking since the jar command included with the JDK distribution allows us to create ZIP files (jar files are just zip files).

We use CMake's standard find_package script that gets installed when you install CMake on your Linux. This in turn means that the problem is 99.99% on the side of your CMake version or the software installation on your Linux boxen....

Looking into the FindJava.cmake file it looks like it's only a problem in CMake's error message (see bottom).

To fix this, you would have to install the JDK.

HTH,
Manuel

Subject: [Seqan-dev] cmake - java version ?

Hi,

when executing "cmake ." I get the following warning:

-- Warning, could not run java --version

when trying to run java, I see it is installed (not a given... ) but
there is no option "--version" just "-version"

Here is what is installed:

java version "1.7.0_25"
OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

I guess it is not that important...

Anyways any idea on how to remove this warning is appreciated...

Thanks,

Bernd
