When I try to create a new SPP task on my system (as described here), I get the following error messages

ecl> xc hello.x

IRAF 2.16.1 was installed in a clean environment by running ./install and accepting all defaults and then sourcing ./unix/hlib/setup.sh. System is Debian Stretch.

The full command line of the gcc command (retrieved with xc -d, reformatted for better readability) is:

gcc -o T_hello.e \  
    -I/home/oles/iraf/bin/unix/hlib/libc \  
    hello.o \  
    /home/oles/iraf/bin/bin.linux64/libmain.o \  
    /home/oles/iraf/bin/bin.linux64/libex.a \  
    /home/oles/iraf/bin/bin.linux64/libsys.a \  
    /home/oles/iraf/bin/bin.linux64/libvops.a \  
    /home/oles/iraf/bin/unix/bin.linux64/libos.a \  
    /home/oles/iraf/bin/bin.linux64/libVO.a \  
    /home/oles/iraf/bin/bin.linux64/libcfitsio.a \  
    /home/oles/iraf/bin/unix/bin.linux64/libf2c.a \  
    -lm -lpthread -lm -lrt  

When using my own compiled binaries, recompilation works nicely.
