The current toolchain for building JavaFX is gcc 8.2. As long as you
don't build WebKit, it will still build with gcc 5.4.
I just tried it on an Oracle Linux 7 machine with gcc 4.9.1 (which is
what we used to use a couple years ago), and the build fails for me with
the same error. Looks like you will need a newer gcc.

Hi,
I did a clean install of CentOS 7, updated, added the necessary tools and
then cloned the repo and ran the default build. I get the following errors:
/home/test00/Source/jfx/modules/javafx.graphics/src/main/native-glass/gtk/glass_general.cpp:598:1:
error: unused parameter ‘event’ [-Werror=unused-parameter]

cc1plus: all warnings being treated as errors

Is this expected? I have not found any documentation specifing the minimum
version of gcc/g++ and wonder if I need to upgrade? I am using g++ (GCC)
4.8.5 20150623 (Red Hat 4.8.5-39). Also, other native code in the build
are treating the unused-parameter as a warning. Why is this module
different?
/home/test00/Source/jfx/modules/javafx.graphics/src/main/native-font/pango.c:429:26:
warning: unused parameter ‘that’ [-Wunused-parameter]
(JNIEnv *env, jclass that, jlong arg0)
Here are the detailed steps I followed:
0. sudo yum update
1. sudo yum install git bison flex pkgconfig gtk2-devel gtk3-devel
pango-devel freetype-devel libXtst-devel java-11-openjdk-devel ant gcc-c++
libstdc++-static
2. sudo alternatives --config java
- specify Java 11
3. git clone https://github.com/openjdk/jfx.git
4. cd jfx
5. bash ./gradelw
Any suggestions is appreciated.
Michael
