Co-existing GLIBC binaries with Void-Linux MUSL edition

I am running void-linux at home with musl as the standard C library.

While most things work well, there is a number of programs that do not and must be using glibc counterparts.

To enable this I followed this guide here: Live switching Void Linux from glibc to musl.

To set-up:

mkdir -p /glibc
sudo env XBPS_ARCH=x86_64 xbps-install --repository=http://alpha.de.repo.voidlinux.org/current -r /glibc -S base-voidstrap

• sudo : yes, we need root
• env : Needed because we are using sudo.
• XBPS_ARCH=x86_64 : architecture to use. Since we are using musl, we point to the glibc version. It should be possible to create a 32 bit root here.
• --repository=http://alpha.de.repo.voidlinux.org/current : the repository to use. Feel free to replace to something closer.
• -r /glibc : directory tree where the glibc executables will live
• base-voidstrap : unlike base-system, this meta-package is normally used for containers.

To keep this tree up to date:

sudo env XBPS_ARCH=x86_64 xbps-install --repository=http://alpha.de.repo.voidlinux.org/current -r /glibc -Su

To add software to the tree:

sudo env XBPS_ARCH=x86_64 xbps-install --repository=http://alpha.de.repo.voidlinux.org/current -r /glibc -S pkg

Once this is set-up you need a small program to kick off the glibc executables. I copied this one:

To compile and install:

gcc -s -o glibc glibc.c
sudo cp glibc /usr/bin
sudo chown root:root /usr/bin/glibc
sudo chmod +sx /usr/bin/glibc

Then you can just run:

glibc cmd args

The following software I have found doesn't work well using musl:

• Calibre
• building buildroot (Because of compilation of fakeroot)
