Hello Floh,
My C++ files are in different packages like some files are inside folder1,
folder2, folder3 and folder4 and some are in parent directory (like abc.cpp
& def.cpp .......) as you can see in below screenshot. So when I ran the
emcc command I think emscripten compiler is confuse with C++ file path. So
how I specify C++ files name with respective folder.
*emcc -O3 --bind folder1/aa1.cpp aa2.cpp aa3.cpp aa4.cpp folder2/bb1.cpp
folder3/cc1.cpp folder4/dd4.cpp abc.cpp def.cpp -o script.js -s
ALLOW_MEMORY_GROWTH=1*
*when i ran the above command got issue -> **emcc: error: aa2.cpp: No such
file or directory ("aa2.cpp" was expected to be an input file, based on the
commandline arguments provided)*
