[LFS] 6.13. Binutils-2.25

The Binutils package contains a linker, an assembler, and other tools for handling object files.


1. Verify that the PTYs are working properly

expect -c "spawn ls"

This command should output the following

spawn ls

2. Indicate library path, and make sure libbfd-2.25.so and libdl-2.20.so is under library folder.

export LD_LIBRARY_PATH=/lib:/usr/lib

3. Make binutils-build and ./configure

mkdir -v ../binutils-build
cd ../binutils-build

../binutils-2.25/configure --prefix=/usr   \
                           --enable-shared \
                           --disable-werror\
                           LIBS=-ldl-2.20

3. Compiler and Install package

make tooldir=/usr

make tooldir=/usr install

Problem:

 error: undefined reference to 'dlsym'
 error: undefined reference to 'dlopen'
 error: undefined reference to 'dlclose'

Method 1:

vim lfs/tmp/binutils-build/Makefile +384
LDFLAGS = --> LDFLAGS = -ldl-2.20

Method 2:

../binutils-2.25/configure --prefix=/usr   \
                           --enable-shared \
                           --disable-werror\
                           LIBS=-ldl-2.20
