Description

Hi,

I think Revision a40aad8f may have caused issues for ARM compilation.

I run the following script to compile

mkdir -p /opt/tvheadendts2
git clone https://github.com/tvheadend/tvheadend.git /opt/tvheadendts2
cd /opt/tvheadendts2

export CC=gcc

bash configure \
--host=armle-unknown-linux \
--target=armle-unknown-linux \
--build=i686-pc-linux \
--disable-avahi \
--release \
--openssl=/opt/lib \
--prefix=/opt/tvheadendts2

make

but today get the following error


./build.linux/src/packet.o: In function `atomic_add':
/opt/tvheadendts2/src/atomic.h:24: undefined reference to `__sync_fetch_and_add_4'

perhaps I need to install some more libraries ?

There was some discussion in #hts about whether or not removing support for older versions of GCC might affect some ARM toolchains. Though most of the ones I've come across people compiling TVH were recent enough not to be affected.

Can you confirm which version of GCC you are using as I believe the problem is that GCC <4.3 (might include 4.3 as well) will no longer work due to the tidy up of the atomic code.

Compiled succesfully on my sheeva with gcc 4.4.7 and 4.6.3 (same configuration, packages version and processor).

Do you use some special ./configure attribute or just ./configure?

#8

Updated by Walter Purcaro about 12 years ago

Just ./configure :)

#9

Updated by Anonymous about 12 years ago

How do update gcc? When I rund apt-get update I just find version 4.4.5.

#10

Updated by Walter Purcaro about 12 years ago

I've took it from debian testing branch (then, I've debian on :D).

#11

Updated by Anonymous about 12 years ago

Now I have tried with gcc 4.6.3 but it still fail:

checking for cc -mmmx ... fail
checking for cc -msse2 ... fail

Any ideas?

I think it's fair to say that your ARM system is not going to support MMX or SSE, so that's not a problem ;)

My fault, of course ARM not supporting MMX and SSE. I get it to work now.

  • Status changed from New to Rejected

Having spoken briefly to Andreas about this, I think the decision is quite clear. We're dropping support for GCC < 4.3 (or more specifically any version that doesn't include the various atomic_ operations).

This is to save us having to maintain our own set for each platform on which people want to run TVH, when most people are using toolchains that already provide the necessary support.

Therefore I think this issue will simply be closed.

If that's going to cause issues please shout! This does not affect 3.2, so if you must run with an older version of GCC I recommend switching to using that release until you can find an updated toolchain.
