Hi Mark and Florian,

You are great! It works perfectly.

Thanks,

Han

Hey Mark,

you are right...I just searched tech-talk for the solution I got.

Andrew suggested the following change, which worked for me

Where the Makefile says something like

  PROD_IOC = <iocname>

replace it with this:

  PROD_IOC_linux-arm = <iocname>
  PROD_IOC += $(PROD_IOC_$(T_A))

The second line is needed, because as you said the syntax is only working for OS_CLASS not T_A.

Cheers,
Florian

I think this syntax only work for OS_CLASS, not for target architecture (TA)

 

So it works for

PROD_IOC_Linux = <name>

 

But for linux-arm I think you need to do:

 

ifeq (linux-arm, $(findstring linux-arm, $(T_A)))

  PROD_IOC_Linux = <name>

endif

Hey Han,

yes, there is a way. I did this once too.

If I remember correctly you simply need to change the line
PROD_IOC = <name>
to
PROD_IOC_linux-arm = <name>
in your <ioc>APP/src/Makefile

Hi EPICSers,

 

I have an IOC, I want to compile it with only target architecture, for example, linux-arm. My host is linux-x86_64. EPICS base and modules can be compiled through the standard method with Host and target well with os/CONFIG_SITE.linux-x86_64.linux-arm.

 

But due to the specific libs, and header files for this IOC, I want to exclude the host compilation.

Is there any way to force to compile this IOC only for target Archture?

 

Best,

Han
