Openframeworks: emmake make fail to compile 3DPrimitivesExample

[edap]

I've just pulled the current master and i was not able to compile the project to emscripten as explained here http://openframeworks.cc/setup/emscripten/

OS: Mac 10.11.5 (15F34)
emscripten SDK version: 1.37.16

Error log
emmake_error.txt

[cuinjune]

I also have this issue on Mac OSX 10.11.6.

[arturoc]

have you tried the nightly builds?

[edap]

I've tried now, same error, log in attachment
errorlog.txt

It can not find the compiler_flags, cat:
Sources/OF/of_v20170714_osx_release/libs/openFrameworksCompiled/lib/emscripten/obj/Release/.compiler_flags: No such file or directory

are they strictly necessary?

[edap]

@arturoc let me know if there is something that I can do, or if you have an idea about something that I could try, I would like to start to fix some issues.

Latest master is working for me on OSX. @edap Have you ran the emscripten download_libs script? See #5613 for a related topic. My problem was that I was overwriting libraries, see #5693 for how to keep all libraries when using both emscripten and desktop builds. Hope this helps.

@chuckleplant I'm having the same issue on OS X, have used -n with both emscripten and osx download_libs scripts but still getting the errors below when I

from the terminal:

I just got it working yesterday with these steps (macOS):

Download and unpack emscripten.

curl -LO https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz && tar xvf emsdk-portable.tar.gz

cd emsdk-portable/

Initialize emscripten.

./emsdk update
./emsdk install latest
./emsdk activate latest

Set up your environement.

source ./emsdk_env.sh

Set MAKEFLAGS to make it compile faster (optional).

export MAKEFLAGS="-j8 -s"

Get the latest version of openFrameworks.

git clone --depth=1 https://github.com/openFrameworks/openFrameworks.git

cd openFrameworks

Install openFrameworks libraries for emscripten.

scripts/emscripten/./download_libs.sh

Go to an example:

cd examples/3d/3DPrimitivesExample/

Copy a MAKEFILE into the example:

cp ../../../scripts/templates/emscripten/Makefile .

Build the project:

emmake make

Run the project.

emrun bin/3DPrimitivesExample.html

[bakercp]

Closing this, as it works with the latest master branch.

[cwervo]

Ah, the steps above worked for me, I suppose the Makefile template was necessary to sort things out. Thanks @bakercp !

[Mach1Studios]

I would like to reopen this as it does not work with all current

[arturoc]

can you create a new issue with the error you are gettng now?
