Hi Alon,
OK I see.
I will try to do more python debug on my side.
Thanks,
Laurent
PS: if you have a working example in the shell using dlfcn that would be
great.

At the end of the diff, it shows that
FS.createLazyFile('/', 'liblib.so', 'liblib.so', true, false);
is missing. In test_core.py, it looks like that is added by the
post_build operation, so I think that isn't running when you build it
manually in the shell.

Hi Alon,
Attached are the two files.
The diff gives many differences.

When you run the test suite with EMCC_DEBUG=1, you should see
the command (in yellow, starting with "invocation:") and
replicating it should produce the same results. Is that what
you are trying? For that test, there are at least two commands
that run, to build the main and side modules, so make sure to
build both.
If that doesn't help, diffing the two outputs might show
something interesting. (On latest emscripten incoming builds
should now be deterministic which makes such diffs easier to
read.)

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:

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

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