For what it's worth, this patch makes TheUnarchiver2.7.1_src.zip build and run for me on wheezy. It just removes -lobjc from the link command. I also have to add -lz, which is already done by a patch in http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=30;filename=theunarchiver_2.7.1-1.debian.tar.gz;att=1;bug=619602.
Without removing -lobjc, the programs compile but enter an infinite loop when run. They also show this warning: gcc -Wl,--whole-archive -fexceptions -fgnu-runtime -o unar unar.o CSCommandLineParser.o CommandLineCommon.o NSStringPrinting.o libXADMaster.a ../UniversalDetector/libUniversalDetector.a -Wl,--no-whole-archive -lgnustep-base -lcrypto -lbz2 -licuuc -lobjc -lstdc++ -lm /usr/bin/ld: warning: libobjc.so.2, needed by /usr/lib64/libgnustep-base.so, may conflict with libobjc.so.3 The relevant packages I have installed are gobjc-4.6 4.6.1-4 libobjc2 4.5.3-5 libobjc3 4.6.1-4 libgnustep-base-dev 1.20.2-2 David Fifield
