Set Your Path Environment Variable
First, ensure that your C++ compiler is set up in your environment and available in the PATH environment variable. See your compiler documentation for information.
HydraExpress also requires your PATH environment variable to point to the bin directory of your JRE. To test whether your PATH points to bin, type java at a command prompt. If your PATH environment variable points to bin, the command returns Java usage help.
If the above test fails, add the location of the JRE bin directory to your PATH:
Windows | set PATH=JRE-location\bin;%PATH% |
UNIX/Linux shell | PATH=JRE-location/bin:$PATH; export PATH |
NOTE: The command for setting environment variables may vary depending on your UNIX shell.
