Hi,
Issue resolved. :)
Modified the make file:
all: singlehello.bc
singlehello.bc: hellomake.o hellofunc.o
$(CXX) $^ -o $@
hellomake.o: hellomake.c
$(CXX) -c $^ -o $@
hellofunc.o: hellofunc.c hellomake.h
$(CC) -c $< -o $@
Remember to set the environment before issue emmake command.
issue: ../emsdk_env.sh
confirm the path : echo $PATH
After this no need to issue commands(emcc,emmake,emconfigure etc) using ./
instead directly used as emcc
issue: emmake make(it will generate the singlehello.bc).
Using emcc, would generate the output js file.
emcc singlehello.bc -o output.js
Regards,
Raman
