I am attempting to compile an old program that was released around 2007 on AlmaLinux 9. To this point I have been able to keep this thing running through all of the OS upgrades but this time it’s been a nightmare.

Whenever I try to compile this code I get these messages:

/bin/sh ../libtool –mode=link gcc -g -O2 -rpath ‘/usr/local/plot/lib’ -L/usr/lib64 -L >-L/usr/lib64 -L/usr/lib64 -L/usr/lib64 -o poll snmp.o dbi.o poll.o util.o targ.o gram.o >hash.o -lnetsnmp -lgd -lpng -lltdl -lz -lrt -lpthread -lm

(I’m not wholly certain why it has “-L/usr/lib64” 4x on that previous line.)

mkdir .libs

collect2: error: ld returned 1 exit status

and this ultimate output:

make[1]: *** [Makefile:528: poll] Error 1

Here are lines 526-528 of Makefile:

poll$(EXEEXT): $(poll_OBJECTS) $(poll_DEPENDENCIES) $(EXTRA_poll_DEPENDENCIES) 
        @rm -f poll$(EXEEXT)
        $(AM_V_CCLD)$(poll_LINK) $(poll_OBJECTS) $(poll_LDADD) $(LIBS)

make[1]: Leaving directory ‘/home/zct/build/src’
make: *** [Makefile:395: all] Error 2

Here are the lines

394-395:

        $(MAKE) $(AM_MAKEFLAGS) all-am

I can’t tell if the ld messages are the reason the compilation is stopping or if those are just informational/warning messages.

Literally any nudge in the right direction is appreciated. I’ve fixed quite a few oddities to get to this point so far. Thank you.
