Good morning all,
I am installing OpenFOAM 5.x in my $HOME directory, and when it compiles the libOpenFOAM.so I got the next error:

Make/linux64GccDPInt32Opt/primitives/ints/int64/int64IO.o: In function `Foam::operator>>(Foam::Istream&, long&)':
int64IO.C:(.text+0x860): multiple definition of `Foam::operator>>(Foam::Istream&, long&)'
Make/linux64GccDPInt32Opt/primitives/ints/int32/int32IO.o:int32IO.C:(.text+0xab0): first defined here
Make/linux64GccDPInt32Opt/primitives/ints/int64/int64IO.o: In function `Foam::operator<<(Foam::Ostream&, long)':

Make/linux64GccDPInt32Opt/primitives/ints/int32/int32IO.o:int32IO.C:(.text+0xac0): first defined here
collect2: error: ld returned 1 exit status

Has anyone experienced this?
Many thanks in advance!

Quick answer: I'm guessing here that you are using the default GCC 4.4 in RHEL 6.5. This version of GCC is not going to work.

The step by step installation instructions provided here: https://openfoamwiki.net/index.php/I...HEL#CentOS_6.9 - should still work on CentOS 6.5.
