How do I specify -rpath in my makefile

Instead of using LD_LIBRARY_PATH, I want to specify the library search path through the -rpath option in the makefile. How can I do that? Assume the search path is the current directory.

The -rpath flag needs to be passed to the linker. Prefix all flags with -Wl to have gcc pass them to ld, e.g.

LDFLAGS = -Wl,-rpath -Wl,.

You have three options:

  • use LDFLAGS to specify options for ld

  • create separate rules for compilation and linking, there you can parr -rpath=/what/ever to ld directly

  • use -Wl,ldoption for gcc to propagate ldoption to linker. In your case:

    gcc ... -Wl,rpath=/what/ever ...

Note that LD_LIBRARY_PATH serves for the dynamic linker/loader (ldd) not for the linker that creates executables (ld).

Example

LDFLAGS += --rpath-link /home/hp/Desktop/staging_dir/target-mips_uClibc-0.9.30.1/root-brcmref/lib/ld-uClibc.so.0

Example of make file:

all: test


%.o: %.c
    $(CC) $(CFLAGS) -c -o $@ $^

test: test1.o test2.o
    $(CC) $(LDFLAGS) -o $@ $^
