[x264-devel] x264 for sparcV9

[Sean McGovern]

Pass --disable-asm to configure, and then re-run gmake.

Rebuilding often? Use gmake -j `/usr/sbin/psrinfo -p`

Want to follow proper Solaris standards for library placement? Add --libdir=\${exec_prefix}/lib/sparcv9 to configure, and then don't forget to symlink sparcv9 to '64' in the lib directory.

Yes, I see your point, I added m64 to LDFLAGS but now I get the following:

gcc -o x264 x264.o input/input.o input/timecode.o input/raw.o input/y4m.o
output/raw.o output/matroska.o output/matroska_ebml.o output/flv.o

ld: fatal: Symbol referencing errors. No output written to x264

collect2: ld returned 1 exit status

 

I'm just using configure with the appropriate variables and running the
Makefile as it came from the git repo. Do I need to tell it something else
to not link in pixel.o?

 

Thanks,
David

Also, pixel.o shouldn't be built or linked in as its not 64-bit.

Hi Sean,

Thanks for the reply, I'm using gcc 4.3.2 and I ran configured with 

#CFLAGS="-m64 mcpu=v9" ./configure

 

And then ran gmake. Unfortunately, I'm getting a linking error related to
the ELFCLASS of the x264.o object file. I'm thinking this is something
simple that I'm not remembering. Would you mind taking a look at my build?

 

I appreciate your help,

David

No, it should compile stock provided you are using a recent version of gcc
-- 3.4.3 from Solaris 10 is ever so slightly on the old side. You might want
to get your hands on GCCFSS or Blastwave. I built my own gcc 4.5.2 against
SunFreeware's binutils package. 

I've been working with the x264 team to keep this building properly "out of
the box" on SPARC.

Hi Sean,

I'm a graduate student doing research with x264 and I need to compile a
64-bit version for sparcv9. I noticed that you are distributing solaris
packages of exactly what I need, except I need to modify the source code.

 

Did you have to do anything special to get x264 to compile for 64-bit other
than pass m64 to the compiler?

 

Thanks for your help,
David
