I’m experimenting with Docker and as a nice trial project that would also allow
me to build MacOS custom builds of lilypond I decided on trying to get GUB up
and running in a Docker container on my Mac (Docker’s for Mac 1.12.3).
Looking at lilypond.org/gub all I would need is a Linux environment with some
basic tools installed, so I went off starting with a bare Docker CentOS7 image
yum-installed
git
python
gcc
gcc-c++
created a regular user for GUB, switched to that user and cloned the GUB repo
of Graham Percival
then gub bootstrap ran into missing make
so I yum installed make to get it in place
then gub bootstrap ran into missing msgfmt
so I yum installed gettext to get it in place
And then gub bootstrap decided to fail with an error on darwin-ppc::odcctools
which I (not having done prior cross-platform builds nor any serious
development on linux boxes) could not find an explanation for… hope one of you
could shine some light on it:
