#2 cannot compile - Kubuntu 11.10 (Oneiric Ocelot) SOLVED (ish)

[linkedupbits]

The error is
module.o: In function uncompress_module': module.c:(.text+0x248): undefined reference toinflateInit_'
module.c:(.text+0x299): undefined reference to inflate' module.c:(.text+0x2b9): undefined reference toinflateEnd'
module.c:(.text+0x2e7): undefined reference to `inflateEnd'
collect2: ld returned 1 exit status
make: *** [rb-download] Error 1

Note - if you modify the Makefile so that:
LDFLAGS+=-lz -v

you get the default linker command

This gives the error above.

If you edit the linker command above to:
/usr/lib/gcc/x86_64-linux-gnu/4.6.1/collect2 --build-id --no-add-needed --as-needed --eh-frame-hdr -m elf_x86_64 --hash-style=gnu -dynamic-linker /lib64/ld-linux-x86-64.so.2 -z relro -o rb-download /usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu/crt1.o /usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu/crti.o /usr/lib/gcc/x86_64-linux-gnu/4.6.1/crtbegin.o -L/usr/lib/gcc/x86_64-linux-gnu/4.6.1 -L/usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu -L/usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../../lib -L/lib/x86_64-linux-gnu -L/lib/../lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../.. -lz rb-download.o list.o findmheg.o listen.o command.o stream.o assoc.o carousel.o module.o table.o dsmcc.o biop.o fs.o channels.o cache.o utils.o -lz -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/gcc/x86_64-linux-gnu/4.6.1/crtend.o /usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu/crtn.o

(ie an extra -lz before the -lgcc) it sucessfully links.
