I am trying to install BerkeleyDB STL . I ran the following code to download n install the same
curl -OL http://download.oracle.com/berkeley-db/db-6.2.23.NC.tar.gz
tar xf db-6.2.23.NC.tar.gz
cd db-6.2.23.NC/build_unix
../dist/configure --prefix=$HOME --enable-stl
make
make install
then for further installation of my application i need to tell R where is BerkeleyDB STL, for which I did as stated by the manual :
CPPFLAGS=-I${HOME}/include
LDFLAGS=-L${HOME}/lib -Wl,-rpath=${HOME}/lib
But I get the following error while running the second command :
bash: -Wl,-rpath=/home/mayankmodi/lib: No such file or directory
even though the directory structure is
.
├── bin
├── env
├── include
├── lib
└── Videos
*I have deleted most of my folders to make it easy to spot lib directory
QUESTION: I need to understand the implication of
LDFLAGS=-L${HOME}/lib -Wl,-rpath=${HOME}/lib
The line
LDFLAGS=-L${HOME}/lib -Wl,-rpath=${HOME}/lib
with the HOME variable expanded, becomes
LDFLAGS=-L/home/mayankmodi/lib -Wl,-rpath=/home/mayankmodi/lib [rest of actual command]
which is interpreted as something close to
EnvironmentVariable=Value command line ...
i.e. Bash interprets the text -Wl,-rpath=/home/mayankmodi/lib as the start of a command or path to an executable, and attempts to run it with the environment variable setting LDFLAGS=-L/home/mayankmodi/lib, which fails because there's no such command or program.
To fix this, you can wrap the value to be given to LDFLAGS in double quotes:
LDFLAGS="-L${HOME}/lib -Wl,-rpath=${HOME}/lib"
so that LDFLAGS expands to the desired text.
