Hi Nab,

For header files that the compiler will find in standard system locations (e.g. /usr/include, etc.) you just need to include types.h in your C or C++ source file.  You don't need to do anything to your Makefile.

For system libraries that will be found in standard locations (/usr/lib, /usr/local/lib, etc) you need to add a line like this to your Makefile (this is for libtiff).

example_SYS_LIBS += tiff

If you have more questions let me know.

Mark

Subject: Building an EPICS App for a Linux Target

Hello,

I am currently using EPICS Base 3.14.12.6 with a linux x86_64 machine and am a relatively new user to EPICS.

I want to run an EPICS Application as a Linux target instead of a VxWorks target and was told that the method to do
so was to edit the "App/src/" directory's Makefile but not sure as to how to approach that task.

How does a user add the support libraries needed for certain C code subroutines from their usr/include path?
For example, I need to add the "types.h" header file. I notice there are flag statements (+=) in the makefile as follows:

# Build the main IOC entry point where needed
example_SRCS_DEFAULT += exampleMain.cpp
example_SRCS_vxWorks += -nil-

# Link in the code from our support library
example_LIBS += exampleSupport

I suspect that if I can add the necessary support libraries, then my EPICS app and database will function correctly.

Thanks for the help,
Nab Rahman
