Compilation problem

[Anonymous]

I try to compile FreeFileSYnc 5 on fedora 17 x64, make and make install output
no errors but once I launch FreeFileSync I got :


FreeFileSync: error while loading shared libraries: libboost_thread.so.1.49.0: cannot open shared object file: No such file or directory


What is wrong ?
Thanks in advance !

It cannot find the dynamic boost libraries which should be located in
/usr/local/lib (or /usr/lib)
. Did you manually install boost according to "compile.txt"?

[Anonymous]

It's a little odd because the library is actually located there :


sudo find /usr | grep libboost_thread.so
/usr/local/lib/libboost_thread.so.1.49.0
/usr/local/lib/libboost_thread.so


But I will desintall boost and reinstall manually.

[Zenju]

Very strange, the file is in fact existing and at the right location. Maybe a
"sudo ldconfig /usr/local/lib" helps?

Now, when I call make I am stuck with :

I'll yum boost and retry with "sudo ldconfig /usr/local/lib"

Oh well I think I messed up... So to start clean, I uninstalled boost and
boost-thread from my package manager, then I followed the compile.txt, after


./bootstrap.sh --prefix=/usr/local/ --with-libraries=thread


I got :


Unicode/ICU support for Boost.Regex?... not found.


Is it bad ?
I assumed it isn't so I ran ffs make again (after sudo ./bjam --clean install
and sudo ./bjam install) and got :

If it's a problem with boost, what other boost libs should I uninstall to
start clean ? Some kde apps seems to depend on them.

You should do a "make clean", then try again.

> Unicode/ICU support for Boost.Regex?... not found.


Is this a warning, error or info message? Generally, this should not be a
problem, since we need boost::thread only; unless boost::thread internally
depends on regex.

[Anonymous]

The message is an info message, so it mustn't be the problem.
I followed your instruction, I did make clean and this time ffs compiles fine,
but then again I got :


FreeFileSync: error while loading shared libraries: libboost_thread.so.1.51.0: cannot open shared object file: No such file or directory


Same as before but with version 1.51, probably because my lib boost is more
recent this time. To be sure I ran :


sudo find /usr | grep libboost_thread.so
/usr/local/lib/libboost_thread.so.1.49.0
/usr/local/lib/libboost_thread.so.1.51.0
/usr/local/lib/libboost_thread.so


I removed the boost thread installed by package manager, I don't understand
why the .so is still there. Anyway, why ffs can't open the .so although it's
in the right place ?

Thanks.

Finally I did your other suggestion :


"sudo ldconfig /usr/local/lib"


It is working now ! Thanks a lot.
