Subject: static libraries

Hi Tech-talk,
I need to use a library in an EPICS app, set up using MakeBaseApp. It wants to have a static version of the library, which the library package doesn't supply. Why does it need the static library? I'm not trying to build a static program. Here's the Makefile fragment which builds it:

PROD_HOST += display
display_SRCS   += display.c
display_LIBS   += ezca
display_DIR    = /usr/local/lib/
display_LIBS   += ssd1306_i2c
display_LIBS   += $(EPICS_BASE_HOST_LIBS)

and it gives:

make[1]: *** No rule to make target '../../lib/linux-arm/libssd1306_i2c.a', need
ed by 'display'.  Stop.

I'm building it natively on a Zynq Debian 10 system. The shared libraries are in /usr/local/lib:
/usr/local/lib/libssd1306_i2c.la  /usr/local/lib/libssd1306_i2c.so.0
/usr/local/lib/libssd1306_i2c.so  /usr/local/lib/libssd1306_i2c.so.0.0.3

Pete.
