How to cross compile redis for ARM32bit on Ubuntu x86_64 ?

[Eli Ko]

I have tried to install arm-linux-gnueabi-gcc and add CC=arm-linux-gnueabi-gcc in Makefile before compiling but it didn't work. There is no ./configure in redis path so I don't know how to regenerate Makefile

Cross-building Redis is not trivial.

You'd much rather invoke the following (after installing Docker on your x64 machine):

mkdir /tmp/redis-5.0.5-arm32v7

cid=$(docker create arm32v7/redis:5.0.5)

docker cp $cid/:/usr/local/bin/redis-server /tmp/redis-5.0.5-arm32v7

docker cp $cid/:/usr/local/bin/redis-cli /tmp/redis-5.0.5-arm32v7

Further instructions can be provided if you require Ubuntu-specific build.

Thank you so much. I've copied redis-server and redis-cli, but there are some errors when I trying to run redis.

/tmp/usr/src/a/redis-5.0.5-arm32v7 # ./redis-server 

-sh: ./redis-server: not found

/tmp/usr/src/a/redis-5.0.5-arm32v7 # ./redis-cli 

-sh: ./redis-cli: not found

I think there are something wrong with my shard library.

$ sudo arm-nuvoton-linux-uclibceabi-readelf -d redis-5.0.5-arm32v7/redis-server

As you're using a uclibc-based system, you'd probably would like to try replacing:

    cid=$(docker create arm32v7/redis:5.0.5)

with

    cid=$(docker create arm32v7/redis:5.0.6-alpine)

to get an Alpine-based Redis build.

However, note that this is a crude solution. One needs to match the uclibc version on your system to the one that is used to build Redis (exact maching is not required, just make sure the versions are compatible).
