# NetSurf for MontaukOS -- native window browser frontend
|
|
#
|
|
# Upstream: https://github.com/netsurf-browser/netsurf (official mirror of
|
|
# git.netsurf-browser.org; submodule at upstream/, pinned).
|
|
#
|
|
# The port reuses NetSurf's compact monkey frontend glue, but MontaukOS builds
|
|
# enter a native Window Server event loop with browser chrome and render into a
|
|
# shared surface. The line-oriented monkey protocol remains available off-OS.
|
|
#
|
|
# CONFIGURATION
|
|
# NETSURF_USE_CURL=NO no libcurl port; fetch_montauk uses MontaukOS DNS,
|
|
# TCP, and the native BearSSL TLS helper.
|
|
# NETSURF_USE_OPENSSL=NO HTTPS is implemented by fetch_montauk via BearSSL.
|
|
# NETSURF_USE_DUKTAPE=NO no JavaScript; also avoids the nsgenbind host tool.
|
|
# NETSURF_USE_JPEG=YES enables the port-local stb_image JPEG/PNG handler.
|
|
# JPEGXL/WEBP/SVG=NO those optional decoder libraries are not ported.
|
|
# NETSURF_FS_BACKING_STORE=YES NOT optional for monkey: frontends/monkey/
|
|
# main.c references filesystem_llcache_table
|
|
# unconditionally, and that lives in
|
|
# content/fs_backing_store.c. The config.h patch
|
|
# already tells NetSurf we lack dirfd/unlinkat/
|
|
# fstatat, so it uses its portable fallbacks.
|
|
# NETSURF_USE_LIBICONV_PLUG=YES means "iconv is already available, do not
|
|
# link -liconv" -- true here, since compat/iconv.c
|
|
# provides it inside libnscompat.a.
|
|
#
|
|
# COMPAT SHIMS (compat/) stand in for headers MontaukOS has no equivalent of:
|
|
# sockets, select, inet, and a stub <curl/curl.h> that exists only because
|
|
# content/fetch.c includes curl's header unguarded. See those files -- each
|
|
# says what it does and does not do.
|
|
#
|
|
# HOST TOOLS: perl, python3. (gperf is needed by libhubbub, not here.)
