#1 The code can not compile on MacOS

When I compiled the code on MacOS 10.15.3 I got the error as shown below

sunjiantaodeAir:libfree bryan$ make gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o in_cksum.o in_cksum.c gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o inet_ntop.o inet_ntop.c gcc -I../lib -g -O2 -D_REENTRANT -Wall -c -o inet_pton.o inet_pton.c ar rv ../libunp.a in_cksum.o inet_ntop.o inet_pton.o a - in_cksum.o a - inet_ntop.o a - inet_pton.o /Library/Developer/CommandLineTools/usr/bin/ranlib: file: ../libunp.a(inet_ntop.o) has no symbols ranlib ../libunp.a /Library/Developer/CommandLineTools/usr/bin/ranlib: file: ../libunp.a(inet_ntop.o) has no symbols

Could you please give some help? Thanks!

Hi, can you try edit the file "configure" at the top level, line 7852, and remove the file name "inet_ntop.o" from that line? The resulting line should look like this:

LIBFREE_OBJS="$LIBFREE_OBJS inet_pton.o" In other words, the build should still use inet_pton.o but no longer use inet_ntop.o since that is provided by your OS.

After making that change, redo the build instructions starting from the ./configure step at the beginning and please let me know if this fixes your issue. If so, I'll commit the change to the repo.

Thanks.
