Author: B Stack Source: Original research Date: 2019-11-21 Message: Main patch to compile on Devuan. This reintroduces the gtk-3 usage, because Debian/Devuan stopped packaging libwxgtk3.0-dev (which used gtk2) and only does libwxgtk3.0-gtk3-dev. However, by reintroducing the gtk3, it brings back the old gtk3 instability from my previous packaging effort: https://freefilesync.org/forum/viewtopic.php?t=4918. /mnt/public/packages/old/freefilesync/freefilesync-9.7-1.master.tgz. Upstream never replied, but did note in the source that gtk3 is inherently unstable. diff -x '*.swp' -x '.git*' -x '*.orig' -x '*.rej' -Naur 10.18-0/FreeFileSync/Source/Makefile 10.18-1/FreeFileSync/Source/Makefile --- 10.11-0/FreeFileSync/Source/Makefile 2019-04-12 08:05:57.000000000 -0400 +++ 10.18-1/FreeFileSync/Source/Makefile 2019-11-21 09:42:57.408243242 -0500 @@ -16,9 +16,10 @@ CXXFLAGS += `pkg-config --cflags libssh2` LINKFLAGS += `pkg-config --libs libssh2` -CXXFLAGS += `pkg-config --cflags gtk+-2.0` +CXXFLAGS += `pkg-config --cflags gtk+-3.0` +LINKFLAGS += `pkg-config --libs gtk+-3.0` #treat as system headers so that warnings are hidden: -CXXFLAGS += -isystem/usr/include/gtk-2.0 +CXXFLAGS += -isystem/usr/include/gtk-3.0 #support for SELinux (optional) SELINUX_EXISTING=$(shell pkg-config --exists libselinux && echo YES) --- 10.20-0a/FreeFileSync/Source/RealTimeSync/Makefile 2020-02-15 17:30:56.738835393 -0500 +++ 10.20-2/FreeFileSync/Source/RealTimeSync/Makefile 2020-02-15 19:09:17.460124615 -0500 @@ -7,9 +7,10 @@ LINKFLAGS = -s -no-pie `wx-config --libs std, aui --debug=no` -lz -pthread #Gtk - support "no button border" -CXXFLAGS += `pkg-config --cflags gtk+-2.0` +CXXFLAGS += `pkg-config --cflags gtk+-3.0` +LINKFLAGS += `pkg-config --libs gtk+-3.0` #treat as system headers so that warnings are hidden: -CXXFLAGS += -isystem/usr/include/gtk-2.0 +CXXFLAGS += -isystem/usr/include/gtk-3.0 CPP_FILES= CPP_FILES+=application.cpp diff -x '*.swp' -x '.git*' -x '*.orig' -x '*.rej' -Naur 10.18-0/wx+/dc.h 10.18-1/wx+/dc.h --- 10.18-0/wx+/dc.h 2019-11-21 08:24:23.967769384 -0500 +++ 10.18-1/wx+/dc.h 2019-11-21 09:42:12.779786504 -0500 @@ -54,7 +54,7 @@ #ifdef wxHAVE_DPI_INDEPENDENT_PIXELS //pulled from wx/window.h: https://github.com/wxWidgets/wxWidgets/blob/master/include/wx/window.h#L2029 return d; //e.g. macOS, GTK3 #else //https://github.com/wxWidgets/wxWidgets/blob/master/src/common/wincmn.cpp#L2865 - static_assert(GTK_MAJOR_VERSION == 2); + static_assert(GTK_MAJOR_VERSION == 3); //GTK2 doesn't properly support high DPI: https://freefilesync.org/forum/viewtopic.php?t=6114 //=> requires general fix at wxWidgets-level assert(wxTheApp); //only call after wxWidgets was initalized! diff -x '*.swp' -x '.git*' -x '*.orig' -x '*.rej' -Naur 10.18-0/FreeFileSync/Source/base/icon_loader.cpp 10.18-1/FreeFileSync/Source/base/icon_loader.cpp --- 10.18-0/FreeFileSync/Source/base/icon_loader.cpp 2019-11-21 08:24:23.955769262 -0500 +++ 10.18-1/FreeFileSync/Source/base/icon_loader.cpp 2019-11-21 09:42:15.439813730 -0500 @@ -18,7 +18,7 @@ namespace { -static_assert(GTK_MAJOR_VERSION == 2, "FreeFileSync does NOT (currently) support GTK3!
