Errors when installing DPDK on Linux Alpine

Question

I am trying to install DPDK on Alpine Linux. I am running Alpine Linux in the Docker. Here are the steps I am using:

docker pull alpine
docker run -it alpine /bin/sh
wget https://git.dpdk.org/dpdk-stable/snapshot/dpdk-stable-16.11.8.tar.gz
tar -xzf dpdk-stable-16.11.8.tar.gz
cd dpdk-stable-16.11.8
apk add --no-cache make gcc libc-dev bsd-compat-headers linux-headers musl-dev
apk add numactl-dev --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrusted
make install T=x86_64-native-linuxapp-gcc

Installation fails with the following errors and warnings:

make[5]: Nothing to be done for 'depdirs'.

I fixed some of the errors but now new errors appear. Here are the updated steps:

docker pull alpine
docker run -it alpine /bin/sh

If you take a look at the /usr/include/x86_64-linux-gnu/bits/socket.h, struct cmsghdr is defined as following:

/* Structure used for storage of ancillary data object information.  */
struct cmsghdr
{
    size_t cmsg_len;
    /* Length of data in cmsg_data plus length
       of cmsghdr structure.
       !! The type should be socklen_t but the
       definition of the kernel is incompatible
       with this.  */
    int cmsg_level;     /* Originating protocol.  */
    int cmsg_type;      /* Protocol specific type.  */
#if __glibc_c99_flexarr_available
    __extension__ unsigned char __cmsg_data __flexarr; /* Ancillary data.  */
#endif
};

What is __glibc_c99_flexarr_available? Can I somehow make this available?

UPDATE 2

I tried to use this instead of musl-dev but the error remains the same.

Then as suggested, I installed glibc on my Alpine Linux to use it instead of musl. Follow the steps here. Now I am getting errors like this:

In file included from /dpdk-stable-16.11.8/lib/librte_eal/linuxapp/eal/eal.c:48:0:

/usr/include/limits.h:124:26: fatal error: limits.h: No such file or directory

It seems DPDK is not compatible to musl libc, so you'll probably have a very hard time fixing errors one by one. Having to manually add preprocessor defines and includes to CFLAGS seems like a bad sign.

The last error is such a libc incompatiblity:

/dpdk-stable-16.11.8/lib/librte_eal/linuxapp/eal/eal_vfio_mp_sync.c:78:24: error: 'struct cmsghdr' has no member named '__cmsg_data' memcpy(&(fd), (chdr).__cmsg_data, sizeof(fd))

In my glibc (Ubuntu 16.04), cmsghdr is defined as follows in bits/socket.h:

/* Structure used for storage of ancillary data object information.  */
struct cmsghdr
  {
    size_t cmsg_len;            /* Length of data in cmsg_data plus length
                                   of cmsghdr structure.
                                   !! The type should be socklen_t but the
                                   definition of the kernel is incompatible
                                   with this.  */
    int cmsg_level;             /* Originating protocol.  */
    int cmsg_type;              /* Protocol specific type.  */
#if (!defined __STRICT_ANSI__ && __GNUC__ >= 2) || __STDC_VERSION__ >= 199901L
    __extension__ unsigned char __cmsg_data __flexarr; /* Ancillary data.  */
#endif
  };

Note the definition of __cmsg_data at the end.

In musl, cmsghdr is defined as:

struct cmsghdr {
        socklen_t cmsg_len;
        int __pad1;
        int cmsg_level;
        int cmsg_type;
};

Note the missing __cmsg_data field.

And if I use [this](https://github.com/sgerrand/alpine-pkg-glibc) instead of `musl-dev`, it is also not working i.e. it shows the same error. — NutCracker, Oct 11 '18 at 13:02
It may still pick the musl headers; the image should provide a compatible `glibc.so` to link against but I'm not sure about the glibc headers setup — valiano, Oct 11 '18 at 13:12
But I definitely agree going for a `glibc` build is probably the best way forward — valiano, Oct 11 '18 at 13:15
First I would try figuring out what is the compatible glibc version, the one with the `__cmsg_data` definition, and how to get that on Alpine. I think the worst case is having to build and install glibc from source. — valiano, Oct 11 '18 at 14:03
If you're not bound to Alpine, you could consider a different light base image (not as slim as Alpine though), perhaps one of the slim debian ones — valiano, Oct 11 '18 at 14:05

Finally, after some time and lots of workarounds I have managed to install DPDK on Alpine Linux i.e. on a Docker container running Alpine Linux.

Here is a Dockerfile I created (comments are inline):
