I've embedded a simple PlantUML sequence diagram in a C source file. When I call plantuml directly with the C file the sequence diagram is produced; however, when I use Doxygen I don't get a sequence diagram or any warnings related to plantuml.
My sequence diagram is basically:
/**
* @startuml
* a->b : func()
* b->c : func()
* c->d : func()
* d->e : func()
* e<-d : func()
*
* a->c : func2()
* c->e : func2(a)
*
* a->c : func3()
* c->d : func()
* d->e : func()
* e<-c : func4()
* @enduml
*/
Versions: doxygen 1.8.15, plantuml 1.2019.00
Thanks.
