Hello folks
I try to built Julia for a custom Alpine linux armv7 on Docker. The container I use is this one ([https://github.com/balena-io-library/base-images/tree/master/balena-base-images/device-base/zc702-zynq7/alpine/3.12](https://github.com/balena-io-library/base-images/tree/master/balena-base-images/device-base/zc702-zynq7/alpine/3.12))
After some time of compilation I get the following error
```
In file included from /home/rgerzagu/work/julia/src/processor.cpp:844:
/home/rgerzagu/work/julia/src/processor_arm.cpp:13:31: warning: "__GLIBC_PREREQ" is not defined, evaluates to 0 [-Wundef]
13 | #if defined(_CPU_AARCH64_) || __GLIBC_PREREQ(2, 16)
| ^ ~~~~~~~~~~~~~
/home/rgerzagu/work/julia/src/processor_arm.cpp:13:45: error: missing binary operator before token "("
13 | #if defined(_CPU_AARCH64_) || __GLIBC_PREREQ(2, 16)
| ^
make[1]: *** [Makefile:165: processor.o] Error 1
make[1]: *** Waiting for unfinished jobs....
```
I understand that it is link to the fact that the Linux uses musl and not libc but not sure how I can handle that (it is possible though ?)
Thanks in advance
Robin

I don’t know much about this but there has been a recent post with successful build for ARM:
> [@Have a try Julia v1.4.2 for arm32bit](https://discourse.julialang.org/t/have-a-try-julia-v1-4-2-for-arm32bit/40284):
>
> Since Julia for arm32bit (e.g. RaspberryPi series) reduced toTier3, [Download Julia](https://julialang.org/downloads/) does not provide, binary Julia 1.4.2. sob Good news! I’m happy to announce the release of recipe (technically Dockerfile) that builds Julia v1.4.2 for RaspberryPi series. See [GitHub - Julia-Embedded/jlcross: Dockerfiles for arm devices e.g. Raspberry Pi Series](https://github.com/Julia-Embedded/jlcross) You can enjoy Julia on your Raspberry Pi 3 or 4 even Zero smile Does Julia packages runs on Raspberry Pi ? As far as I know…
Maybe you find some help there.

I believe it’s fixed recently.

Thank you very much for the feedback.
I switch to the master branch, and the error disappears… which is great and I get a new one ☝ !

Again, any clue on this would be greatly appreciated !
