This page is a random collection of tips for when you have difficulty building Orx.

You need to run setup.sh / setup.bat to get the Orx dependencies.

This will occur if:

1. You never ran setup before, or:
2. You've done a git pull for the latest and forgot to run setup again for the latest dependencies.

The setup command should be automatic when first cloning. Try running ./setup.sh or setup.bat again.

For specific mingw issues, see the troubleshooter on this page.

If you get the above error in VS2015, it is because you need VS2015 Update 3. You can update under Tools / Extensions and Updates. Choose `Update 3`. This will download the installer to your machine. You'll need to close Visual Studio while you run the update.

Just some glitch out there in the matrix, like a network timeout. Just try ./setup.sh again.

If you are building under Linux, you may possibly encounter this error while trying to compile

 /usr/bin/ld: cannot find -lsndfile

You require the libsndfile-devel package. For Fedora:

 yum install libsndfile-devel
 

Or in Debian or Ubuntu:

 apt install libsndfile1-dev
