directory. Then, start Ch shell using command cl or nmake for
compilation.
To compile From ChIDE, Click menu bar Tools --> Compile to compile
your C code.
If you install Microsoft Visual Studio or Express Edition after Ch has been
installed, run "ch -d" to copy the configure file _chrc to your home

Q: How to install Ch Professional Edition in a teaching lab?
There are two ways to install Ch Professional edition in a lab.
Both solutions allow you to re-image machines in a lab easily.
You can just select one that meets the guideline for your lab.
- You can use a floating license server and install Ch Professional Edition
in the lab. The floating license server can control the maximum number of
machines to use Ch Professional simultaneously.
You need to provide the Mac address, host name and operating system of your
floating license server, and the operating system and
number of floating client machines in the lab.
Please note that the client machines need to have the access to the
floating license server to check out a license at run time.
- If you don't have a floating license server machine or don't have
the internet connection between clients and server at run time, you
need to install a individual license for each machine.
You need to provide us with the Mac address and operating system for all machines
in your lab. We can then
create a single license file which can be used for all machines. A single license file
is easy to set up in the master machine to duplicate for other machines in the lab.
When you provide the operating system of your machine,
you need to specify if it is 32 bit or 64 bit machine.
You need to download Ch Professional Edition (actually Ch Professional
Evaluation Edition) from here.
Once a proper license file is in place,
Ch Professional Evaluation Edition will become
Ch Professional Edition.
In Windows,
we offer a special Ch Professional Edition that allows
silent installation via Active Directory push.
A system administrator for your teaching lab can
contact us about how to get such a binary.

Q: How to handle the license error after installing the license file?
-
ERROR: installing a demo license for ch_professional v7.0.0 failed
No "rlm_demo" license available (-139)
This error means that the license file is corrupt. You may
find another way to download the attached license file to copy over
to the license directory.
