Hi Andrew,

 

If I delete the installed version of libVimbaCPP .so and run make it installs that file and I don’t get that error:

 

corvette:areaDetector/ADVimba/vimbaSupportCPP>rm ../lib/linux-x86_64/libVimbaCPP.so

rm: remove write-protected regular file '../lib/linux-x86_64/libVimbaCPP.so'? y

corvette:areaDetector/ADVimba/vimbaSupportCPP>make

make -C O.linux-x86_64 -f ../Makefile TOP=../.. \

    T_A=linux-x86_64 install

make[1]: Entering directory `/home/epics/devel/areaDetector-3-8/ADVimba/vimbaSupportCPP/O.linux-x86_64'

Installing shared library ../../lib/linux-x86_64/libVimbaCPP.so

Installing library ../../lib/linux-x86_64/libVimbaCPP.a

make[1]: Leaving directory `/home/epics/devel/areaDetector-3-8/ADVimba/vimbaSupportCPP/O.linux-x86_64'

 

However, if I simply run make again I now get that error:

 

corvette:areaDetector/ADVimba/vimbaSupportCPP>make

make -C O.linux-x86_64 -f ../Makefile TOP=../.. \

    T_A=linux-x86_64 install

make[1]: Entering directory `/home/epics/devel/areaDetector-3-8/ADVimba/vimbaSupportCPP/O.linux-x86_64'

make[1]: Circular libVimbaCPP.so <- ../../lib/linux-x86_64/libVimbaCPP.so dependency dropped.

Thanks,

Mark

Hi Again Mark,

I have a fairly simple Makefile (attached) to build a support library for areaDetector/ADVimba.

 

It seems to work OK, but I get this message when I build:

 

corvette:areaDetector/ADVimba/vimbaSupportCPP>make -s

make[1]: Circular libVimbaCPP.so <- ..//../lib/linux-x86_64/libVimbaCPP.so dependency dropped.

 

Any idea why I am getting that?

Your first line says TOP=../ instead of the more usual TOP=.. which is what's causing the double-slash ..//.. in the path given in that warning message, but that's benign.

Have you tried doing a 'make distclean' recently? I'm using the Jenkins epics-areaDetector build workspace to look at it and I have the current ADVimba git master branch building in vimbaSupportCPP without getting that error. Base-3.14 fails to install any of the .hpp files because it doesn't have a vpath for finding %.hpp files, but this change fixes that:

diff --git a/vimbaSupportCPP/Makefile b/vimbaSupportCPP/Makefile
index 8fb0165..d09ce0a 100755

 INC += $(patsubst ../%, %, $(wildcard ../VimbaCPP/Include/*))
 
 LIBRARY_IOC_WIN32 += VimbaCPP

I don't have a build against a newer Base though, so I'm not sure what else might be going on.
