Ok, I've been trying stuff along those lines, and I've gotten to a very
weird conclusion:* this happens only if the target dir in the emscripten FS
is "/data"*. If I change the name to anything else, it works.
For example, all these give me zero-sized files:
em++ -std=c++11 main.cpp -o main.html --embed-file "data"
em++ -std=c++11 main.cpp -o main.html --embed-file "data@data"
em++ -std=c++11 main.cpp -o main.html --embed-file "data@/data"
em++ -std=c++11 main.cpp -o main.html --embed-file "data@/data/"
But all these work correctly:
em++ -std=c++11 main.cpp -o main.html --embed-file "data@data2"
em++ -std=c++11 main.cpp -o main.html --embed-file "data@foo/data"
em++ -std=c++11 main.cpp -o main.html --embed-file "data@data/foo"
This seems like a pretty specific bug!
I hope there's an easy fix for this.
Kind regards,
Jon Valdes
