+ <para>When writing shell functions, you need to be aware of BitBake's
+ curly brace parsing.
+ If a recipe uses a closing curly brace within the function and
+ the character has no leading spaces, BitBake produces a parsing
+ error.
+ If you use a pair of curly brace in a shell function, the
+ closing curly brace must not be located at the start of the line
+ without leading spaces.</para>
+ <para>Here is an example that causes BitBake to produce a parsing
+ error:
+ <literallayout class='monospaced'>
+ fakeroot create_shar() {
+ cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
+ usage()
+ {
+ echo "test"
+ ###### The following "}" at the start of the line causes a parsing error ######
+ }
+ EOF
+ }
+ </literallayout>
+ Writing the recipe this way avoids the error:
+ <literallayout class='monospaced'>
+ fakeroot create_shar() {
+ cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
+ usage()
+ {
+ echo "test"
+ ######The following "}" with a leading space at the start of the line avoids the error ######
+ }
+ EOF
