Failing to build C dependency for arm musl target

[vmanucharyan]

I'm trying to compile project with miniz-sys dependency for armv7-unknown-linux-musleabihf and getting the following error:

running: "arm-linux-gnueabihf-gcc" "-O3" "-ffunction-sections" "-fdata-sections" "-fPIC" "-static" "-march=armv7-a" "-Wall" "-Wextra" "-o" "/target/armv7-unknown-linux-musleabihf/release/build/miniz-sys-20caae3d7d97477f/out/miniz.o" "-c" "miniz.c"
cargo:warning=In file included from /usr/include/stdlib.h:24:0,
cargo:warning=                 from miniz.c:177:
cargo:warning=/usr/include/features.h:367:25: fatal error: sys/cdefs.h: No such file or directory
cargo:warning=compilation terminated.
exit code: 1

Is it trying to use wrong toolchain (gnueabihf instead of musleabihf) or am i missing something?

Here is full compilation log:

Did you ever find a solution for this? I basically am encountering a similar issue where it can't find ncurses.h for some builds on travis

[briansmith]

I am getting the same error about missing sys/cdefs.h when doing cross build --target=armv7-unknown-linux-musleabihf for ring.

Here's the path of includes:

In file included from /usr/include/stdint.h:25:0,
                 from /usr/lib/gcc-cross/arm-linux-gnueabihf/5/include/stdint.h:9,
                 from include/GFp/base.h:64,
                 from crypto/internal.h:112,
                 from crypto/block.c:15:
/usr/include/features.h:367:25: fatal error: sys/cdefs.h: No such file or directory

That is, #include <stdint.h> is broken.

I think maybe the Docker image on Docker Hub is out of date.

When working on #255 I had to re-build the Docker image for this target from source using ./build-docker-image.sh armv7-unknown-linux-musleabihf. Once I did that, and after adding the following Cross.toml to my project, I was able to get cross test --target=armv7-unknown-linux-musleabihf to work.

[target.armv7-unknown-linux-musleabihf]
image = "japaric/armv7-unknown-linux-musleabihf:latest"

Thanks @briansmith. I was having the same problem and that fixed it.

[reitermarkus]

I guess this should be working now that the new images are available on Docker Hub.
