RE: Linking agains .so library on linux

["Madden, Timothy J." <tmadden@aps.anl.gov>]

Thanks (again) Mark.

I got it to work as long as I copied the libs to my ADPCO/lib/linux_x86_64 dir.
To point the linker to the right dir I am using:

PROD_LDFLAGS +=-Wl,-rpath,/local/pco/sisw/lib64

That path does show up in the final link command, but it cannot find the libs in that dir. How does one tell a directory with PROD_SYS_LIBS?

Make file is like this:

PROD_LDFLAGS +=-Wl,-rpath,/local/pco/sisw/lib64
PROD_LIBS += pco 
PROD_LIBS += cameralink caputRecorder
PROD_SYS_LIBS += clsersis display fglib5  


The command is like  below. The only snag at this point is that I don't know how to point the linker to the proper dir containing the PROD_SYS_LIBs.

Thanks again
T

You need to reference your vendor .so file using PROD_SYS_LIBS not PROD_LIBS.

Dear EPICS:


I want to link an IOC against an .so supplied by a vendor. The compile seems to only look for .a type libraries.
Also I notice that on linking, -Bstatic is turned on. (I am using linux).
I have epics base CONFIG_SITE file set to:
SHARED_LIBRARIES=YES

#  Build client objects statically ?
#        must be either YES or NO
#
STATIC_BUILD=NO

This seems like it should work.

How do I get rid of the -Bstatuc on my link, so it will look for .so files on link?

Here is the failing command:
