Comment 1 for bug 87436

Trying to build the suspend package utility s2ram on Feisty 32-bit I also ran into this problem. Based on what other people had said I believed initially it was a bug in the pciutils package, and libpci in particular.

After considerable hacking about between the configure scripts and Makefiles of pciutils/libpci and suspend-0.5 I realised that the compiler/linker errors detailed above were a bug in the Makefile of suspend-0.5.

pciutils/libpci is installed to /usr/lib/libpci.a and is a static library. It in turn relies on the zlib static library /usr/lib/libz.a. In its configure script it correctly passes the linker parameter "-lz" which causes ld (the GNU linker) to link libpci against libz.

suspend-0.5's Makefile omits to pass the same "-lz" to the linker, although it does pass "-lpci" correctly. Adding "-lz" as an additional linker parameter, and using LD_FLAGS in the s2ram target rule, solves the problem:

LD_FLAGS=-L/usr/local/lib
LD_FLAGS += -lz

s2ram: s2ram.c dmidecode.c whitelist.c radeontool.c $(S2RAMOBJ)
 $(CC) $(CFLAGS) -g s2ram.c $(S2RAMOBJ) $(LD_FLAGS) -lpci -o s2ram

I'm guessing that compilation issues with other source packages are caused by this same error in their configure scripts and/or Makefile.
