Folks,

I am trying to build the EPICS Xspress3 driver.  It builds fine on Centos 7 with gcc 4.5

On Ubuntu 18 with gcc 7.4 I get this error:

*************

/usr/bin/ld: /corvette/home/epics/devel/areaDetector-3-8/xspress3-2-2/lib/linux-x86_64-ub18/libimg_mod.a(img_mod_linux.o): relocation R_X86_64_32 against `.rodata' can not be used when making a PIE object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
/corvette/usr/local/epics-devel/base-7.0.3.1/configure/RULES_BUILD:212: recipe for target 'xspress3App' failed
make[1]: *** [xspress3App] Error 1

*************

libimg_mod.a is a pre-built library provided by the vendor.  Is there something I can change in the link options to avoid this error, or do we need to get a new library from the vendor?

Thanks,
Mark
