Undefined references when using as shared library

[ghost]

Hey there, I'm trying to use peg-markdown as a shared library built by this Makefile:

CC=clang
CFLAGS=-c -g -Wall

all: clog
    $(CC) obj/main.o -Llibs/peg-markdown -lpeg-markdown -o clog

clog: src/main.c peg-markdown
    $(CC) $(CFLAGS) src/main.c `pkg-config --cflags glib-2.0` -o obj/main.o

peg-markdown:
    make CC="gcc -fPIC" -C libs/peg-markdown/ library

The generation of the .so seems to work fine but when I try to compile my main program, clang just tells me it does not know how to deal with the gstring stuff:

clang obj/main.o -Llibs/peg-markdown -lpeg-markdown -o clog
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_string_new'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_slist_free'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_slist_reverse'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_string_free'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_slist_prepend'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_string_append_printf'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_string_append'
libs/peg-markdown/libpeg-markdown.so: error: undefined reference to 'g_string_insert_c'

I tried using clang 3.3 and gcc 4.8.1

I don't know. You might write to the person who contributed the patch for building a shared library. (Look at the commit logs.)

You might have to add pkg-config --libs glib-2.0 to your compiling rule of 'clog' to link the glib.

pkg-config --libs glib-2.0 did not change anything.
