@William-Scott Thanks I literally just found that about the same time as your reply.

@crispyoz I know it's insufficient, I was hoping against hope that someone had experience with cross-compiling redis. I know the C language from way back, but I'm pretty sure I'm just stuck on how to use the redis build tools correctly.

I can't find ssh-keygen, and running 'opkg install ssh-keygen' says it's an unknown package. How do I get ssh-keygen on the omega?

So I'm able to cross-compile a hello world app and run it on the Omega. Sweet! Now for the real test - compile redis. I followed the suggestion of using the XCompile.sh template, but there are still things I need to learn. Fairly early in the compile, I get this error:

zmalloc.h:50:10: fatal error: jemalloc/jemalloc.h: No such file or directory

I wish I knew enough to provide additional information, but cross-compiling big apps like redis is a real slog. Hoping there's someone with this kind of experience that can help.

@crispyoz wow, that worked! So I also got an error message when I started the make:

WARNING: your configuration is out of sync. Please run make menuconfig, oldconfig or defconfig!

Nonetheless, the make succeeded with no other warnings. I re-ran 'make menuconfig' and saw that my settings were still correct, except it didn't save the target board (Omega 2+). So I've fixed that an am running make again, which I imagine will still work. I didn't get the above error message after fixing the target board in menuconfig.

So thanks a bunch for the help!

I followed the instructions listed at https://docs.onion.io/omega2-docs/cross-compiling.html, and am stuck at a build error. Here is the entire build output for 'make':

make: *** [world] Error 1

I have assumed those warnings are not the cause of the build error, but otherwise there is little to go on so far.

So I follow that up with 'make -j1 V=s' as instructed, and when I make that call, the build never throws an error - instead, it gets stuck at the same place in the build (no matter how many times I try it, or if I do 'make clean' first, or if I use sudo, or reboot, etc). The build proceeds just fine until it reaches this line:

mkdir -p /home/mike/omega-cross-compile/source/staging_dir/packages/ramips

(The username is 'mike' obviously.)

I've let this run for over a day to see if it's taking tens of hours to do whatever it's trying to do after creating the directory, but I never see further progress. I did confirm that the ramips directory got created. Any thoughts on what is blocking me? Thanks.
