Error building with Make

[Crell]

Trying to run make ends with this error:

+ USERID=
+ docker-compose -p phpwasm run --rm -e PKG_CONFIG_PATH=/src/lib/lib/pkgconfig -e PRELOAD_ASSETS=preload/ -e INITIAL_MEMORY=1024MB -e ENVIRONMENT=web -e EMCC_ALLOW_FASTCOMP=1 emscripten-builder cp -v build/php-web.js build/php-web.wasm ./dist

cp: target './dist' is not a directory
ERROR: 1
make: *** [Makefile:203: php-web.wasm] Error 1

When I try to run the php-web.wasm target's dependencies directly, I see there is a warning from SQLite:

I don't know if that's related or not.

Is the problem still occurring with the latest updates?

I got i different error message, i think i was able to get further

Did you ever get past your error @jimmywarting ? I am experiencing the same thing. When I do a docker-compose run emconfigure works for libxml2, but not from the make command.

Hi Again:

I got further. During troubleshooting I noticed we both had bash: nproc: command not found. I fixed that first by brew install coreutils. I don't think it made any difference though.

I deleted the original from and uncommented the below.

That way I got up to:

I deleted my working folder and started over as I couldn't remember if I tested after brew install coreutils

Now I get undefined symbol: pdo_sqlite_module_entry error, which is the same as when I added the extra step:

It still fails in the same place. I reasoned that it was broken because of emsdk no longer including fastcomp (emscripten-core/emscripten#11319). So I changed the dockerfile to have:

RUN set -euxo pipefail;\
	apt-get update; \
	emsdk install 1.39.18-fastcomp; \

Unfortunately it errors in the same place with undefined symbol: pdo_sqlite_module_entry still. My product idea depends on being able to use this wordpress plugin so I will keep on trying. Since it wasn't working anyways I moved both places in the dockerfile to:

FROM emscripten/emsdk:latest
MAINTAINER Sean Morris <[email protected]>

SHELL ["/bin/bash", "-c"]

RUN set -euxo pipefail;\
	apt-get update; \
	emsdk install latest; \

I would really appreciate any help!!!!

[seanmorris]

@rhildred Can you pull the latest master and give it another shot? I've made some changes and its now building with emscripten 3.1.43.

Hi @seanmorris . Thanks for the update. I will give it a try.

I dug through this, and it happens when the binary was built with vrzno, but not pdo. PDO is now turned on by default to prevent this from happening.

Vrzno and PDO will eventually become shared libraries.
