# Dockerfile to build icon without graphics, producing
# - statically and dynamically linked iconx
# - statically linked icont
# Note that the dynamic linking is linked:
# - to musl https://musl.libc.org/
# - rather than glibc https://www.gnu.org/software/libc/
FROM eschen42/alpine-cbuilder:release-v3.14.0
# Note that this image does not /usr/include/X11/Xlib.h, so:
# - `make Configure` rather than `make X-Configure`
# - do not copy the graphics content from IPL
