I want to add the shared library path to my Makefile. I have put in the export command in the makefile, it even gets called, but I still have to manually export it again.
What is the correct approach?
Makefile:
SOURCES = kwest_main.c fusefunc.c dbfuse.c logging.c dbbasic.c dbinit.c dbkey.c metadata_extract.c plugins_extraction.c import.c
LIBS = -L$(LIB) -lfuse -lsqlite3 -lkw_taglib -ltag_c -ltag -Wl,-rpath=.
INCLUDE = ../include
LIB = ../lib
EXE = kwest
CC = gcc
CCFLAGS = -g -Wall -Wextra -std=gnu99 -pedantic-errors -I$(INCLUDE)
OFLAGS = -c
ARCH = $(shell getconf LONG_BIT)
X = -D_FILE_OFFSET_BITS=$(ARCH)
OBJECTS = $(SOURCES:.c=.o)
$(EXE) : $(OBJECTS)
$(CC) -o $(EXE) $(OBJECTS) $(LIBS)
%.o: %.c
$(CC) $(OFLAGS) $(CCFLAGS) $<
fusefunc.o: fusefunc.c
$(CC) $(OFLAGS) $(CCFLAGS) $< $X
kwest_libs: kw_taglib
--->export LD_LIBRARY_PATH=$(LIB):$LD_LIBRARY_PATH
kw_taglib: plugin_taglib
plugin_taglib: plugin_taglib.o kwt_upd_meta.o
gcc -g -shared -I$(INCLUDE) -Wl,-soname,libkw_taglib.so -o $(LIB)/libkw_taglib.so -ltag -ltag_c plugin_taglib.o kwt_upd_meta.o
plugin_taglib.o:
gcc -c -g -I$(INCLUDE) -Wall -Wextra -pedantic-errors -std=gnu99 -fPIC -ltag_c -c plugin_taglib.c
kwt_upd_meta.o:
g++ -c -g -I$(INCLUDE) -Wall -Wextra -pedantic-errors -fPIC -ltag kwt_upd_meta.cpp
c: clean
clean:
rm -rf *.o
rm -rf *.db
ca: cleanall
cleanall: clean
rm -rf $(EXE)
ob: cleanall
rm -rf ~/.config/$(EXE)/
Execution:
$ ./kwest mnt
./kwest: error while loading shared libraries: libkw_taglib.so: cannot open shared object file: No such file or directory
$ export LD_LIBRARY_PATH=../lib:D_LIBRARY_PATH
$ ./kwest mnt
"executes correctly"

The usual way is to copy the dynamic library during the default make and to one of the standard library path
or one of your project library path and add the library to executable using
during make install.
