Installation problems with Ubuntu

ROOT

Dear root,

I’m trying to install root 5.16 on an Ubuntu linux system. After about 15 mins of compilation it gives me a long list of linker problems of the type:

Any ideas on what is going wrong?

Thanks,

Hi,

I don’t know of any problems with GCC 3.4 and Cintex and I cannot reproduce this. Do you really use Ubuntu GCC 3.4.6? Usually people use 4.something nowadays. GCC 3.4 works with ROOT 5.16; it has been built many many times. So it’s maybe the installation you have, or an incompatible linker version.

Do you need cintex? If you don’t know what it is then you probably won’t miss it :slight_smile: Just ./configure --disable-cintex should get you going.

Cheers, Axel.

In fact, I had problems with gcc/g++ 4.2 so I installed 3.2, I then I get the errors I described.

Disabling cintex worked, thanks for the hints!
