Hello!

I am facing a problem, it was easier with Redis 4, I can compile 4.0.11 no problem, but now with the latest jemalloc is giving me an error saying:

Do you guys have an idea what it could be?

Thank you so much.

@p3x-robot did you finally manage to cross compile redis 5 for arm? I'd like to do that but I can't find any information on how to configure the makefile to use arm-linux-gnueabi-gcc or arm-linux-gnueabihf-gcc instead of gcc.

i only have the openwrt version:

Thank you @p3x-robot for your soon reply. I've had a look in your readme to look for some inspiration but the easiest way for the moment I think is still to build redis directly on my raspberry pi zero (hope it'll finish before the end of the Universe).

i think raspberry pi should would have no problem to build redis. piece of cake

Comment From: p3x-robot

for me what giving was problem is the jemalloc, so i disabled jemalloc and it was no problem then

Thank you again for your support. Finally I tried to build it directly on raspberry pi zero and it didn't take too much time. On arm architectures jemalloc should be disabled by default (this is what I understand by reading here and inside the makefile). Anyway I think having a simple way to configure the build environment for cross compilation would be a nice-to-have, so I've created a new issue for the feature request #6014

To save anyone like me a little searching, you would do this by passing MALLOC=libc when calling make
