Functions not being called in travis

Deployment v2
1

I’m working on a C++ project that I am starting with uses a GNU Makefile, The makefile contains many functions, one of which calls other functions. I noticed that in the Travis-CI log, this function does not successfully call the other functions, instead, it leaves a blank space, which causes the build to fail. it does work locally however…

The function is:

define Compile
mkdir -p $(@D)
if [[ $(2) == Linking ]]; then \
  $(call Print,$(2) $(@F),$(WIDTH)); \
else \
  $(call PrintCpp,$(2) $(@F),$(WIDTH)); \
fi
$(1) 2> $@.log; \
  RESULT=$?; \
  if [ $RESULT -ne 0 ]; then \
    $(cross); \
  else \
    $(check); \
  fi; \
  cat $@.log; \
  rm -f $@.log
endef

The functions called are:

define Line = 
$(shell printf '%0.1s' "$(2)"{1..$(1)})
endef

define Print
var="$(1)"; \
    width="$(2)";\
    printf '%s%*.*s' "$var" 0 $(($width - ${#var} - 1)) "$(call 
Line,$(2),.)"
endef

define PrintCpp
var="$(1)"; \
    var=${var%.*}.cpp; \
    width="$(2)";\
    printf '%s%*.*s' "$var" 0 $(($width - ${#var} - 1)) "$(call 
Line,$(2),.)"
endef

define check =
    printf "%b\n" "$(OK_COLOR)\xE2\x9C\x94 $(NO_COLOR)"
endef

define cross =
    printf "%b\n" "$(ERR_COLOR)\xE2\x9D\x8C $(NO_COLOR)"
endef

any help would be great…

Hey @HILLBILLYHeisT,

Looking over your Makefile, it seems to me that the nested calling of functions is causing the error.

made my makefile a bit less complex and renested some functions, it worked… thanks @Montana

Great to hear I could solve your issue.
