Installing dependencies on CentOS

[mstfck]

Hello!
I need a bit help here with CentOS.
I need to build datacoin on CentOS, i install all of the dependencies using yum, but it doesn't set any paths, so make can still not detect it, so i decided to build from source. I built Boost lib, it worked great, before it showed libboost errors, but now it says db_cxx is missing, i know its BerkeleyDB, i also built that from source. I saw it was installed in /usr/lib, so i added this to the make string:

Code:

-L/usr/lib

I tried: ld -L/usr/lib -l db_cxx

It works, but when i use make it won't detect, any ideas how i can fix it?

I am not familiar with CentOS

Build with:

Code:

make -f makefile.unix BOOST_LIB_SUFFIX=-mt

this should resolve your linking issue. Let me know if you need further help, i build it for myself on rhel 6.4 today.

Boost library works, but BerkeleyDB doesn't work. And i can't find where yum installs the files

Please post the error you encounter.

Makefile.my is copy of makefile.unix, it just adds some OpenSSL paths
Makefile.unix returns the same error

ld -l db_cxx returns:

is the package db4-cxx installed? you can verify with:

Code:

rpm -qa | grep cxx

if not install this package using yum.

root@host [~]# rpm -qa | grep cxx
db4-cxx-4.7.25-18.el6_4.x86_64

It is installed!

[nbkn]

the correct path where the file should be (x86_64 rpm which is installed) is /usr/lib64, could this be the problem?
