While classes with a dash in the name are valid (there are plenty in oe-core/poky itself), they cause error when using EXPORT_FUNCTIONS. How to reproduce: 1) define the following "dashed-class.bbclass": dashed-class_do_custom_function() { # do nothing } EXPORT_FUNCTIONS do_custom_function 2) use do_custom_function inside a recipe Bitbaking will result in the following error: dashed-class_do_custom_function: not found Renaming the class to "nondashedclass.bbclass" and fixing the function definition accordingly doesn't cause the problem, so my guess is that dashed are not parsed properly in functions definition. 47799 1 richard.purdie 2015-01-08 10:40:14 +0000 dash characters are illegal in sh function names. There isn't anything we can do about that (and we don't want to mandate bash, we can't due to our sh parser anyway) so I've made sure you get a clear early error at parse time from bitbake instead explaining the problem: http://git.yoctoproject.org/cgit.cgi/poky/patch/?id=2e26745a134373dfde3aa2b16fef3df720436e77
