Hi Guys, 

           I'm trying to install CPLEX 12.7.1 on my MacBook Pro with touch bar installed with OS X 10.12. I made sure that java is installed and "java -version" works fine

 

QQs-MacBook-Pro:Downloads QiuFeng$ java -version

java version "1.8.0_141"

Java(TM) SE Runtime Environment (build 1.8.0_141-b15)

Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode)

 

 

 

      However, when I executed the bin file, it says Java is not installed. Any thought on this? I appreciate your inputs. I remember the installation several years ago was quite easy. I guess the installation file didn't update to the latest os environment. 

      By the way, I looked around here but previous posts on this matter seemed not very help

I'm not sure if it will help, but did you see this thread? As you have already done, it suggested that you make sure "java -version" works. It might be worth trying the other suggestion, though, to set LAX_VM. For convenience:

 

<installer> LAX_VM <path/to/java>

Thank you rkersh, the LAX_VM things seem to be helpful. But there was another error, which seems to be ever rarer:

Sorry, I should have been more explicit above. I believe you need to set LAX_VM to the fully qualified path to the java executable. For example, on an OSX system I have access to, if I run "which java" at the command line, I get "/usr/bin/java". So, I'd use the following command (not actually tested, just an example):

 

$ ./cplex_studio12.7.1.osx.bin LAX_VM /usr/bin/java

 

Instead of "/usr/bin/java", you'd use the path that you get on your system.

Hi rkersh, 

            Thanks for the details. I tried your way, still didn't work. When I ran which java, I got the same path as yours. Then using that info in the installation gave me the same error message:

 

QQs-MacBook-Pro:Downloads QiuFeng$ which java

/usr/bin/java

QQs-MacBook-Pro:Downloads QiuFeng$ ./cplex_studio12.7.1.osx.bin LAX_VM /usr/bin/java

Hi

Could it be issues with libs ? Could you test with a jdk instead , following install instructions here  ?

Hi Christophe, 

                 It works! It looks that the java I installed is only a subset of JDK. Thank you!

HI, COULD YOU OPEN THE CPELX NORMALLY? I CAN ONLY ACCESS CPLEX USING  TERMINAL OF MAC, IT IS SO STRANGE...

This has been discussed many times in the Forum here. On Mac there is no IDE at the moment. This will change in the upcoming 12.8 version, see here.
