Hi Michael,

Thanks, adding the second line below to the Makefile fixed it.

PROD_SYS_LIBS += giomm-2.4 
PROD_SYS_LIBS += gio-2.0 gobject-2.0 gthread-2.0 glib-2.0

I was puzzled why it worked previously when the Makefile contained only the first line, i.e. giomm=2.4.

I think I have figured it out.  If I add this line to the Makefile it builds fine without the second line above:

STATIC_BUILD=NO

If it is building dynamically then libgiomm-2.4.so has the information it needs to know what other libraries are required.  But if I build statically then I need to specify the other libraries.  When this worked previously for me I must have been building dynamically.  Does this make sense?

Thanks,
Mark

This is the same issue once removed.  -lgobject is missing.

pkg-config is your friend here.

aravis 0.3.8 lists it's dependencies as

> glib-2.0 gobject-2.0 gio-2.0 libxml-2.0 gthread-2.0

https://github.com/epicsdeb/aravis/blob/master/aravis.pc.in#L9

copy+paste these to pkg-config

> -lgio-2.0 -lgobject-2.0 -lxml2 -lgthread-2.0 -pthread -lglib-2.0

So your

is missing gobject, gthread, and glib itself.

These results on debian 9 w/ glib 2.50.3-2, your mileage may vary.
