Description

Hi,

I'm getting a warning and several errors when compiling tvheadend:

Rene,

Sorry for the delay, I've not been around for a few days.

I'm afraid this is not a bug but is by design. From TVH 3.4 onwards GCC 4.3+ will be required. The reason we're doing this is that from that version onwards GCC includes built-in support for various atomic operations.

This means that Andreas doesn't need to maintain various atomic_ ops himself. As he's intending to use some new routines for which we've previously had no implementations this seemed the right time to make the switch.

For now you will need to stick with 3.2 or (if possible) update your toolchain.

Oh okay :( Do you think it's sufficient to compile a newer version of gcc or do I have to compile some other tools, too?

#3

Updated by Adam Sutton almost 12 years ago

I honestly don't know :( I'd try asking the synology guys, I know Diaoul sometimes frequents #hts so if you can't get hold of them any other way try there, I might poke him myself and see if I can get some info from him.

Found this post: http://www.synology-forum.de/showthread.html?21316-Installation-mkvtoolnix-auf-DS-211&p=196912&viewfull=1#post196912

He's describing how to compile all dependencies for gcc and gcc itself - even with c++ support, if needed. I'm trying the same rigth at the moment,
but without c++ support. Will report back.

Compiled gcc 4.7.2 succesfully on my NAS :)

Here are my steps (inspired by the post mentioned above - thanks to scythe42!):

# maybe a good idea to put this into .profile
export LD_LIBRARY_PATH="/opt/lib/:/lib/:$LD_LIBRARY_PATH" 

# if it's not already symlinked
ln -s /opt/bin/bash /bin/bash

# get latest versions of GMP, MPFR, MPC, libelf, gcc and unpack them
ftp://ftp.gmplib.org/pub
http://www.mpfr.org/mpfr-current
http://www.multiprecision.org/index.php?prog=mpc&page=download
http://www.mr511.de/software
ftp://gcc.gnu.org/pub/gcc/releases

# compile gmp
./configure --prefix=/opt
make
make install

# compile mpfr
./configure --prefix=/opt
make
make install

# compile mpc
./configure --prefix=/opt
make
make install

# compile libelf
./configure --disable-nls --prefix=/opt
make
make install

# fix some problems which would occur during gcc build process
ln -s /opt/arm-none-linux-gnueabi/lib/crt1.o /usr/lib/crt1.o
ln -s /opt/arm-none-linux-gnueabi/lib/crti.o /usr/lib/crti.o
ln -s /opt/arm-none-linux-gnueabi/lib/crtn.o /usr/lib/crtn.o
ln -s /opt/include /usr/include

# compile gcc, gcc is then able to compile c source code only
# took nearly 20h to compile, be patient ;)
./configure  --disable-nls --disable-multilib --disable-libgomp --oldincludedir=/opt --prefix=/opt --enable-languages=c
make

# remove old gcc
ipkg -force-depends remove gcc

# install new one
make install

Now I'm able to build the latest versions of tvheadend!
