problem when compile

[AlbertnQ]

Sorry for bothering.When I tried to use the command "emconfigure cmake ..",it reports error: use 'emcmake' rather then 'emconfigure' for cmake projects. So I used ' emcmake cmake ..', it also report error,like the following:

configure: cmake .. -DCMAKE_TOOLCHAIN_FILE=/home/samfisher/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake -DCMAKE_CROSSCOMPILING_EMULATOR="/home/samfisher/emsdk/node/12.9.1_64bit/bin/node"

Thanks for submitting this issue.

What Emscripten SDK version are you using? Try dl the latest one from https://emscripten.org/docs/getting_started/downloads.html. I successfully compiled this project using the latest Emscripten SDK a couple of weeks ago.

What cmake version are you using?

[AlbertnQ]

Yes, I used the latest Emscripten SDK. And my cmake version is 3.13.3.

Now I can compile by using 'emcmake cmake..', but when I 'make -j4' ,it reported many errors:
(it seems to be caused by dependency library, such as boringssl?)

I'm having difficulty reproducing your errors. I updated emsdk to the latest version (per https://emscripten.org/docs/getting_started/downloads.html, I pulled the latest changed and ran "./emsdk install latest", "./emsdk activate latest", "source ./emsdk_env.sh"). Cloned a clean copy of tpm-js, initialized submodules ("git submodule update --init"), and built it with:
mkdir bulid-web
cd build-web
emcmake cmake ..
make -j4

You were right about changing "emconfigure cmake .." to "emcmake cmake ..", I also got that error.
But after that, the build completed successfully.

Maybe you're missing "build-essential" package?
I can maybe move the build process to a docker image. Would that work for you?

Note that if you only want to go through the code-labs, TPM-JS live web site is at: https://google.github.io/tpm-js/. Unless you want to change the codelabs, there's no real need to rebuild the project.

[AlbertnQ]

Thanks for your help. If it's convenient for you, please provide docker image to me. I want to learn this framework, but I met lots of problems when building, even though I used the same instructions as you did above. Sorry for bothering.

[cfircohen]

I added an emsdk Dockerfile and a couple of helper shell scripts in 77d7b80.

Please pull, delete your "build-web" dir if you have any and run:
$ ./dcmake
$ ./dmake -j4

The first prepares the Docker image, creates 'build-web' directory, and invokes cmake in the Docker image. You need to run this only once.

The second runs make in the Docker image.

Please give it a try.

[AlbertnQ]

RUN groupadd -g $group builder \
    && useradd -u $user -g $group builder \
    && mkdir -p /home/builder \
    && chown -R builder:builder /home/builder

I think groupadd command use -g to add a new group that has a new gid, but $group gid may have been used, will it cause an error?And the second command useradd -u may be the same.

[cfircohen]

These are arguments set by dcmake.sh and dmake.sh. Please look at the shell scripts.

[cfircohen]

Sorry, arguments set by dinit.sh when it builds the image:

docker build
--build-arg user="$(id -u "${USER}")"
--build-arg group="$(id -g "${USER}")"
-t tpm-js-builder-image .

[AlbertnQ]

Yes.
In dinit.sh,

docker build
--build-arg user="$(id -u "${USER}")"
--build-arg group="$(id -g "${USER}")"
-t tpm-js-builder-image .

User is current user's uid, and group is current user's gid, so in dockerfile,useradd and groupadd may cause error 'uid is not unique' and 'gid is not unique'.Because they are used.When I compile ,it's actually like this. After I change them, it can work normally now and I can run the web.
Thank you very much!Thanks for your help!

[cfircohen]

I'm glad it works for you. Thanks for your interest in this project.
