How to install a custom boost version in CentOS?

Question

I'm trying to compile and install boost 1.54 from source in CentOS.

The documentation is pretty straight forward and there are plenty of tutorials in the internet available (1) (2) (3). This is what I did:

wget http://sourceforge.net/projects/boost/files/boost/1.54.0/boost_1_54_0.tar.gz
tar -xzvf boost_1_54_0.tar.gz
cd boost_1_54_0
./bootstrap.sh --prefix=/usr/local
./b2 install --with=all

This is compiling and installing boost correctly to /usr/local/lib and everything looks fine.

Now I compile other software that requires boost using gcc and everything works fine. From my understanding everything should be OK as long as gcc finds the required libs.

But now the problem: If I run my compiled binaries I get the following error:

./myProgram
  ./myProgramm: error while loading shared libraries: libboost_system.so.1.54.0: cannot open shared object file: No such file or directory

Why can the libraries not be found?

In addition I tried:

ldconfig
locate boost
  [...]

But boost libraries can not be found. I've looked for the path manually, it is:

/usr/local/lib/libboost_system.so.1.54.0

I also tried to create symlinks to /usr/lib but this doesn't fix this either.

Any ideas? What can I do?

Answer 1

You have to add -Wl,-R/usr/local/lib to the LDFLAGS when compiling your program.

-R is a linker option (for specifying a runtime linker path) - -Wl instructs gcc to pass it to ld.

With shared libraries you have to make sure that they are found by the linker during compile and during runtime (cf. flags -L and -R).

You can use

$ ldd myProgramm

to verify if the runtime-linker path was set correctly, i.e. if it can find the needed shared libraries on program start/which shared libraries it will load.

Answer 2

As a workaround, I believe you can prefix the running of the executable with the environment variable LD_LIBRRAY_PATH and give it the path to the directory which contains the .so library.

Example

$ LD_LIBRARY_PATH=/usr/local/lib ./myProgram

But it sounds like the method you've used to compile the application in question is not correct. I'd need to see your compilation method for myProgram to be more specific.

Got boost 1.54 version installed in CentOS 7 with the below commands:

sudo wget http://repo.enetres.net/enetres.repo -O /etc/yum.repos.d/enetres.repo

Download the lib64icu42-4.2.1-1mdv2010.0.x86_64.rpm from the below link: ftp://fr2.rpmfind.net/linux/Mandriva/official/2010.0/x86_64/media/main/release/lib64icu42-4.2.1-1mdv2010.0.x86_64.rpm

Install the RPM:

sudo rpm -ivh lib64icu42-4.2.1-1mdv2010.0.x86_64.rpm

Install the required boost library version:

sudo yum install boost-devel-1.54.0

That's it. Have a great day!
