Error building Omnet++: Cannot build Tcl/Tk apps on Mountain lion

Question

I'm trying to Compile Omnet++ 4.1 on Mountain Lion. When I type:

./configure 

I get the following error:

configure: error: Cannot build Tcl/Tk apps, probably due to misconfigured or missing X11 headers or libs. Check config.log for more info!

I remember compiling it on Lion without any problems, any ideas how to get it working on Mountain Lion?

Found a solution for this over on the omnetpp google group, I'll paste it in here:

Hi all,

just tried Mountain Lion, which was released yesterday. Unfortunately, the new MacOSX does not include X11 by default. I really HATE this decision. As a result, it does not pass the Tcl/Tk checks when we do ./configure.

After hours of efforts, I finally figured out how to work around this:

1. download and install XQuartz at http://xquartz.macosforge.org/landing/
2. make a symbolic link at /usr/include: sudo ln -s /opt/X11/include/X11 /usr/include

and you are all set. In 2, you may also set some environment variables accordingly instead of making the symbolic link.

Future OMNet++ releases may consider setting associated environment variables so that the compiler looks for Xlib.h in /opt/X11/include/X11 with Mountain Lion.

Just successfully compiled the simulator and haven't encountered other problems yet.

Have fun, TS

If you have the same problem on Linux (ubuntu) a solution is run this in the console:

sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev openjdk-6-jre doxygen graphviz openmpi-bin libopenmpi-dev libpcap-dev
