Problem with STM32CubeMX install on Mac

[WSank]

I'm running MacOS Mojave 10.14.3, trying to install STMcubeMX 5.1.0. I had to install Java 6 legacy and also JRE 8 build 201. When I try to install from the "en" directory created by the STM32cubeMX download using a terminal, here's what I get: (tried <return> as password the first time which was clearly wrong)

What am I doing wrong ?

computer-name:en userid$ sudo java -jar SetupSTM32CubeMX-5.1.0.exe

Sorry, try again.

This is the exact environment and procedure that I used to install on my Mac and it worked. Some thoughts for you ...

1) Verify that the command line is picking up the right version of java, by executing 'java -version'. The requirements for CubeMX states "On MacOS: Java Development Kit (minimum version 1.7.0_45)"

2) If that checks out, try typing in 'XCode' in your Spotlight and running it to make sure it starts up correctly.

Don't install it as root, and dont put it in Applications.

Hello all,

Thanks for the replies.

I can't see that JDK is needed - I searched all around the CubeMX docs and can't find any reference to it. I'm pretty sure I don't have it but from what I read I can't see now it's needed.

I'm not sure what to do about this, I seem to have 2 versions of JRE:

computer-name:~ userid$ /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version

java version "1.8.0_201"

Java(TM) SE Runtime Environment (build 1.8.0_201-b09)

Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

computer_name:~ userid$ which java

/usr/bin/java

computer-name:~ userid$ java -version

java version "1.6.0_65"

Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468)

Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)

computer-name:~ userid$

I don't know if I have to remove the 1.6.0 version somehow or remove both and reinstall the 1.8.0_201 version ?

OK I think I've found something intestine. On this page:

https://docs.oracle.com/javase/9/install/installation-jdk-and-jre-macos.htm#JSJIG-GUID-2432241F-9517-4C0B-9CBB-489E6419C9C9

it says:

12. I have Oracle's version of the JRE installed, but when I try to run the java command from the command line, it does not work.

Installing a JRE from Oracle does not update java -version symlinks or add the java command to your path. For this functionality, you must install the full JDK.

I'll try to install the JDK and see what happens.

OK that worked, thanks for the help !!!

So... what happens if install as root in applications?

The alternative is ??? install as user and in something like /user/user_name/Applications ?
