The Shader Development Studio3.4 Shader syntax checkingIf you do not have the Offline Compiler available, you can skip this section. For moreinformation about the Offline Compiler, see Mali GPU Developer Tools Overview.Each time a shader source file is saved, the Shader Development Studio compiles the shader inthe background using the offline compiler. If any errors are found, error messages are displayedin:• Problems view.• Alongside the offending line of the shader source file, if it is open in the shader sourceeditor.To see how errors are displayed by Eclipse:1. Open the file simple.frag in the SimpleTest project.2. Remove the semi-colon at the end of the vec4 expression.3. Save the file.A red error marker is displayed on the line beneath the vec4 expression line. SeeFigure 3-21:Figure 3-21 Error indicator in shader source editorSimilar to a C compiler, the offline compiler reports a missing semicolon as an error onthe next line.The removal of the semi-colon generates four separate error messages in the Problemsview.
