Attempting TigerVNC 1.7.0 server build on i386/alpine linux ... almost there!?

[Daniel Garton]

I'm trying to build the Tigervnc server in an i386/alpine (Docker) environment. I manage to build the Viewer after disabling NLS support, but the Server build fails at

make[2]: *** No rule to make target '../../../../common/network/libnetwork.la', needed by 'libvnc.la'.  Stop.

Can anybody shed some light on what I need to tweak or include to get the server to build?
I'm building from https://github.com/TigerVNC/tigervnc/archive/v1.7.0.tar.gz. Please see the following for my build process setup and config.

I'm able to fulfill all the build-time deps by doing:

apk add cmake alpine-sdk zlib-dev fltk-dev gnutls-dev libjpeg-turbo autoconf automake util-macros font-util-dev libtool libxkbfile-dev

Following the instructions as at https://github.com/TigerVNC/tigervnc/blob/master/BUILDING.txt, this is how it goes for me:

# TigerVNC viewer build (succeeds)
I had trouble building the TigerVNC viewer due to libintl_gettext reference errors in linking. Even after I followed the advice at https://www.gnu.org/software/gettext/FAQ.html#integrating_undefined and built and installed gettext from source, I still got those errors, so after

cmake -G "Unix Makefiles" .

I edit config.h to have

#define ENABLE_NLS 0

and then "make" succeeds. NLS support is not critical for me at the moment.

# TigerVNC Server build (fails)
I pull down https://www.x.org/archive//individual/xserver/xorg-server-1.18.4.tar.gz which I believe corresponds to the alpine xorg version I have installed:

xorg-server-dev-1.18.4-r3

and the patch

patch -p1 < <tiger_sourcedir>/unix/xserver118.patch

applies cleanly.
I configure like this (very close to default in BUILDING.txt):

./configure --with-pic --without-dtrace --disable-static --disable-dri --disable-xinerama --disable-xvfb --disable-xnest --disable-xorg --disable-dmx --disable-xwin --disable-xephyr --disable-kdrive --disable-config-hal --disable-config-udev --disable-dri2 --disable-xwayland --enable-glx --with-default-font-path="catalogue:/etc/X11/fontpath.d,built-ins" --with-xkb-path=/usr/share/X11/xkb --with-xkb-output=/var/lib/xkb --with-xkb-bin-directory=/usr/bin

but "make TIGERVNC_SRCDIR=<tiger_sourcedir>" fails like this:

That's very weird. Which .la files do you have under common/? Could you
share the whole build log with us?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
