Build steps causes errors

[johnlai2004]

I followed these instructions in the README.md of the branch linux-support.

1. Make sure Java (version 8 works) is installed. $JAVA_HOME should be set to something like /usr/lib/jvm/java-8-openjdk.
2. Clone this repo and cd into it
3. cd ViroFBX/
4. make This should make the virofbx binary.

I did this on ubuntu 24.04. The last step make gave this error

same error !

I came across this error and solved it installing zlib using "sudo apt-get install zlib1g-dev".

Hi, you should follow this steps :

• sudo apt-get install openjdk-8-jdk
• export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
• make clean && make
