Compiling Redis 2.6.4 on a 32-bit system?

[Dennis McEntire]

I am not sure if this is a resolved issue, but I am trying to compile Redis 2.6.4 on a 32-bit platform. Here's the steps I have taken so far:

1. make 32bit doesn't work, it errors out with this error:

zmalloc.o: In function `zmalloc_used_memory':
/redis-2.6.4/src/zmalloc.c:223: undefined reference to `__sync_add_and_fetch_4'
collect2: ld returned 1 exit status
make[2]: *** [redis-server] Error 1

2. I tried adding a line to the src/Makefile here and it didn't help (last line listed here):

# Default settings
STD= -std=c99 -pedantic
WARN= -Wall
OPT= $(OPTIMIZATION)
CFLAGS= -march=i686

3. Since I am using Mandriva (RH based) I then installed glibc-devel and that didn't help (same error).

I'm at a bit of a loss here; maybe it's no longer compatible with 32-bit systems? I installed 2.4.9 on the same system just before trying 2.6.4 and it worked fine.

Thanks in advance for any help,

Dennis

Also, not sure if this is important, here's what I have on this system:

try using -march=native or -march=i586 option, Even though you already use try -march=i686 

maybe your system use i586 system architecture. wish you luck.

Thank you, I tried these and none of them helped:

CFLAGS= -march=pentium
CFLAGS= -march=native
CFLAGS= -march=i486
CFLAGS= -march=i586
CFLAGS= -march=i686

Maybe I am not putting the line in the right place? I am editing src/Makefile and adding it towards the beginning of the file, here:

# Default settings
STD= -std=c99 -pedantic
WARN= -Wall
OPT= $(OPTIMIZATION)

CFLAGS= -march=i486

After some more looking around, I figured it out. Here's what I did in case it helps someone else:

Edit src/.make-setttings

Modify this line to be like this:

REDIS_CFLAGS=-march=i586

Then it complied and installed properly after that (after using 'make 32bit').

Excuse me how to build it.

just using type "make" or "make 32bit" 

how about this

edit Makefile 

32bit: header

at that time you can see below lines

32bit:

    @echo ""

    @echo "WARNING: if it fails under Linux you probably need to install libc6-dev-i386"

    @echo ""

    $(MAKE) CFLAGS="-m32" LDFLAGS="-m32"

and change it to CFLAGS="-m32 -march=native"

32bit:

    @echo ""

    @echo "WARNING: if it fails under Linux you probably need to install libc6-dev-i386"

    @echo ""

    $(MAKE) CFLAGS="-m32 -march=native" LDFLAGS="-m32"

[CharSyam]

it is because of "make 32bit"

CFLAGS="-m32" maybe overwrite your CFLAGS setting ^^
