[x264-devel] Disregard last email

I just did a git pull. Ran configure like this: CFLAGS="-m64 -mcpu=v9"
LDFLAGS="-m64" ./configure --disable-asm
Then built x264, then I ran it using:
./x264 --qp 20 --partitions b8x8,i4x4 --ref 5 --direct auto --b-pyramid
normal --weightb --mixed-refs --no-fast-pskip --me umh --subme 7 --analyse
b8x8,i4x4 --threads 2 -o eledream.264 eledream_640x360_128.y4m
And it outpur:
y4m [info]: 640x360p 0:0 @ 25/1 fps (cfr)
x264 [info]: using cpu capabilities: none!
x264 [error]: malloc of size 0 failed
x264 [error]: x264_encoder_open failed
And then exited immediately.
But it runs completely if I specify only one thread. Is multithreaded
execution supported on sparcv9?
Thanks,
David

I used git show-branch in that directory and it tells me
"
[master] Hotfix for some bugs in VBV emergency
"
Should I do another pull?
Thanks,
David

What version did you build? There was a git push last night.

Sorry Sean,
I sent that message out prematurely I figured out the problem after I saw
that quiet needed to be removed from the parameter list.
I am having a different problem now though. X264 runs fine if I specify 1
thread. -threads 1, but if I specify 2 or more threads I get:
y4m [info]: 640x360p 0:0 @ 25/1 fps (cfr)
x264 [info]: using cpu capabilities: none!
x264 [error]: malloc of size 0 failed
x264 [error]: x264_encoder_open failed

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

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
