Hi Oleg,
on Linux just extract with tar
$tar -xzf PCL-02.00.13.0689-20141030.tar.gz
and adapt the PCL* environment variables to the directory where you have extracted the archive. That's it.

When you have compiled the INDI module, you have to trigger the installation of the INDI module from PixInsight with -> PROCESS->MODULE->Install Modules ...

Hmm... But the PCL-02.00.13.0689-20141030.tar.gz doesn't contain any binaries: ~/PCL/bin/ folder is empty.

Hi Oleg,
to compile a PixInsight module or plugin you have to statically link against the libPCL-pxi.a library which is in the PCL/lib directory. The compiled PixInsight module, which is technically a shared library, is copied into the PCL/bin directory by the makefile. You can also check the run_build.sh
script on the github repo, this is used to trigger a linux/osx build on travis build server.

Klaus, I can't resolve this problem.

OK, what is exactly the problem.?Do you still get the message from the makefile generator ? When you added the PCL env varibales do not forget to start a new shell (terminal) and start PixInsight from that terminal, so that it runs in an environment where these variables are set. To be sure check your environment, e.g. with

$env | grep PCL (bash shell)...
$PixInsight &
-> start PixInsight from the terminal

The build frameworkis a bit complicated since makefile have to be kept in synch on the three platforms ...

So, I run the PixInsight from terminal and open the PixInsight Makefile Generator script with the following settings:

What is my next step for Linux computer?

PixInsight reports:
==> Generating makefile:
/home/oleh/PixInsightINDIclient/linux/g++/makefile-x64
* Directory created: /home/oleh/PixInsightINDIclient/linux/g++/x64/Release/module
* Directory created: /home/oleh/PixInsightINDIclient/linux/g++/x64/Release/test
* Directory created: /home/oleh/PixInsightINDIclient/linux/g++/x64/Release/test/fakes

==> Generating makefile:
/home/oleh/PixInsightINDIclient/linux/g++/Makefile

Now, I open the terminal and run two commands:

So, I got many files in directory /home/oleh/PixInsightINDIclient/linux/g++/x64/Release/module

OK, then do the following:
cd module/linux/g++/ && mkdir -p x64/Release && make -f makefile-x64

I got the error: make: *** ["/home/oleh/PCL//module/linux/g++/x64/Release"/PixInsightINDIclient-pxm.so] Error 1
See attached file.

Ah, seems that there is something missing in the makefile generation script. You can fix this by creating the directory "/home/oleh/PCL//module/linux/g++/x64/Release" by hand ... so make sure that the directory /home/oleh/PCL//module/linux/g++/x64/Release exists

My head likes a big pumpkin
1. I create the new directory in PCL: /home/oleh/PCL/module/linux/g++/x64/Release
2. I open the terminal and run two commands:3. then I run this comand:and got new directory /home/oleh/PixInsightINDIclient/module/linux/g++/x64/Release
4. then I run this command:and got error: "make: *** ["/home/oleh/PCL//module/linux/g++/x64/Release"/PixInsightINDIclient-pxm.so] Error 1"
