[Bug 878612] Re: Linker fails when compiling fuse files with "undefined reference to `fuse_main_real'

[noon]

LDFLAGS is the variable for the linker flags.
Linker libs such as -lfuse should be put in the LDLIBS variable, not in LDFLAGS.

To solve the problem and simplify the Makefile at the same time:

In the Makefile, the LDFLAGS definition should be replaced with LDLIBS:

LDLIBS := $(shell pkg-config fuse --libs)

Also the 2-line fusexmp_fh section should be simplified with:

fusexml_fh: LDLIBS += -lulockmgr

(To make it even cleaner, there should be separate CFLAGS and CPPFLAGS
pkg-config settings: --cflags-only-other and --cflags-only-I
respectively)

  Linker fails when compiling fuse files with "undefined reference to
  `fuse_main_real'

Bug description:
  I had a working Fuse application when using Ubuntu 11.04, and I'm 99.9% sure I've
  installed everything I need after re-installing Ubuntu 11.10.

  I installed libfuse-dev and copied the 
  /usr/share/doc/libfuse-dev/examples/hello.c file to /tmp and ran the the command
  listed at the top of the file:

  gcc -Wall `pkg-config fuse --cflags --libs` hello.c -o hello

  and it returns:

  /tmp/ccYYt1z4.o: In function `main':
  hello.c:(.text+0x33f): undefined reference to `fuse_main_real'
  collect2: ld returned 1 exit status

  libfuse-dev:
