Hello,
I am trying to run the followingexample using emcc:
python runner.py test_dlfcn_funcs
I saved all the files created by "python runner.py test_dlfcn_funcs" using
export EM_SAVE_DIR=1.
I set export EMCC_DEBUG=2 as well.
In folder /tmp/emscripten_temp I tried to recreate src.c.o.js using the
following invocation command:
emcc \
src.c.o \
-g \
-o src.c.o.js \

--js-transform "/usr/bin/python /tmp/emscripten_temp/transform.py"
As a result file src.c.o.js (file A) created by "python runner.py
test_dlfcn_funcs" and the file src.c.o.js (file B) created by the above
invocation command are different.
If I run nodejs src.c.o.js everything is working fine when using file A.
However file B produce errors:
$ nodejs src.c.o.js
go xxxxxxxxxxxx
ggggggggggggggggggggggggggggggggggggggg /
go
/tmp/emscripten_temp/src.c.o.js:90

Could somebody explain me how to create src.c.o.js correclty without
running the test suite?
Thanks,
Laurent
