How to install a custom boost version in CentOS?
Solution 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.
Solution 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.

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 asgcc
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?

Alen Milakovic over 10 yearsI'd generally recommend building from a suitably chosen source RPM. What CentOS version are you using?
-
Tushar Nallan over 10 yearsCentOS 6.4, I'm not used to this environment, I'm more the Debian/Gentoo guy. I might have a look into the RPMs too.

Alen Milakovic over 10 yearsI use Debian myself. But rebuilding an RPM is not hard. My recommendation is to find a source rpm for boost 1.54 for some version of CentOS. Presumably a more recent version than you are using. Then adjust for your version as necessary.

Tushar Nallan over 10 yearsYeah that works indeed, thanks. But I guess I will have to recompile it with adjusted LDFLAGS.

Tushar Nallan over 10 yearsSetting LDFLAGS at compile time is just working great, thanks!

slm over 10 years@qdoe - yes max's answer shows howto accomplish that!
