Forgot to say that in order to mimic “make install” behavior, I think you only need INSTALL_LOCATION, so you can do something like this

 

INSTALL_LOCATION=/usr/lib/epics make

 

But again you need to have permissions on that directory, or use “sudo”.

Hello Lucas

 

You are right about the behavior of INSTALL_LOCATION, by default it is set to $(TOP), then the build creates directories in INSTALL_LOCATION. This variable is used for staged build along with FINAL_LOCATION, where INSTALL_LOCATION is a temporary build location and FINAL_LOCATION points to the “final” location. I found some notes about these two variables here, you can see a practical use for these two here and here. The EPICS build system is not standard “autotools” based system where you can do stuff like “./configure”, “make” and “make install”.

 

Best Regards,

Abdalla.

Subject: How to use INSTALL_LOCATION with system directories

 

Hi all,

 

Maybe this has already been answered, but I couldn't find this exact question.

 

I have an example support module created with:

 

makeBaseApp.pl -t ioc testInstallLocation

makeBaseApp.pl -i -t ioc testInstallLocation

 

with its configure/CONFIG_SITE file with:

 

INSTALL_LOCATION=/opt/test

 

My expectation was that I would be able to do "make" to compile everything and

"make install" to install the bin, lib, etc, folders to where INSTALL_LOCATION points to,

but that was not the case.

 

With INSTALL_LOCATION different than $(TOP) it tries to create the destination directories 

before compiling anything, thus failing because /opt is owned by root. And doing "sudo make" seems wrong.

 

Is there any better way to do this or to change this behavior? Or is my expectation wrong about the usage of INSTALL_LOCATION?

 

Lucas
