Hello,

I have an application that embeds Yaws, and am in the process of
crafting a release. Not an expert in that domain btw.

I have a couple of questions:

1. I added yaws in the .rel file, when starting yaws from inside
the application i get an {error, {already_loaded..}} when i start
yaws with start_embedded/N.

Is that normal ? For now, i get around this by stopping and
unloading yaws before calling start_embedded. Not the right way,
obviously Smile So what is the correct way of starting yaws embedded
in a larger OTP application ?

2. When making the .tar.gz containing the release, some files
are ommited; typically yaws_api.hrl. What should i do ?

Thanks in advance for your answers,

Olivier,

When you include Yaws in the .app file, mark it as "load". That way
it will not be started until you do so explicitly. You can then start
Yaws in "embedded" mode when it suits you.

Probably somewhat outdated:

Hi, thank you for your answer.

I finally managed it working (yaws-1.75), by adding

{yaws, "1.75", none},

to my application's .rel file. Now yaws:start_embedded works ok.

Could not make it work using the .app file as you said, though.

Now, i have to find out how to get yaws_api.hrl included in the release

Thanks again for the clues,
