Warning Failed to make bytecode for file

Trying to package an app with just --targets node8.6.0-win-x86 in linux. Get dozens of warnings: Warning Failed to make bytecode for file C:\snapshot\app\index.js error (spawn /home/travis/.pkg-cache/v2.3/fetched-v8.6.0-linux-x86 ENOENT).

The resulting app doesn’t work on Windows.

If i enable --no-bytecode, I get:

Error! --no-bytecode and no source breaks final executable /home/travis/build/app/index.js Please run with “-d” and without “–no-bytecode” first, and make sure that debug log does not contain “was included as bytecode”.

With the option disabled and -d enabled I get around one hundred lines with [debug] The file was included as bytecode (no sources) in the logs.

If I launch the same packaging process in macOS, it works fine.

Both pkg@4.2.6 or pkg@4.3.0-beta.5.

I experienced the same issue on GitLab CI. But I was able to build them locally. The solution was to include support for 32-bit executables.

I’m using the node:7 image on GitLab CI as build image. The runners are on a 64-bit host. When debugging locally using docker run -it -v $PWD:/root/vdds-client node:7 /bin/bash I found out that I had the same issue as on the CI: no proper win-x86 output.

Using the -d flag for pkg I saw the following section:

> [debug] Targets:
  [
  {
    "nodeRange": "node6",
    "platform": "win",
    "arch": "x86",
    "output": "/root/vdds-client/client.exe",
    "forceBuild": false,
    "fabricator": {
      "nodeRange": "node6",
      "platform": "linux",
      "arch": "x86",
      "forceBuild": false,
      "binaryPath": "/root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86"
    },
    "binaryPath": "/root/.pkg-cache/v2.5/fetched-v6.11.5-win-x86"
  }
]

When trying to run the /root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86 it gave me the following error:

root@a2cd31593bb2:~/vdds-client# ls /root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86
/root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86
root@a2cd31593bb2:~/vdds-client# /root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86
bash: /root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86: No such file or directory

So I took a look:

root@a2cd31593bb2:~/vdds-client# file /root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86
/root/.pkg-cache/v2.5/fetched-v6.11.5-linux-x86: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=ac11506dd30ec242b56788701d1315efeed93910, not stripped

This triggered the idea that I did include the i386 support locally…

So I was able to fix it for my case (gitlab-ci, node:7 image) by installing glibc with i386 support by adding the following to the .gitlab-ci.yml script section:

    - dpkg --add-architecture i386
    - apt-get update
    - apt-get install -y libc6:i386 libstdc++6:i386

You might need to adapt for your setup;-) Installing ia32-libs instead of multiarch could be also a way, don’t know about non-Debian systems…

@zeit If you can let us know where to start looking into this issue, I’d be very much happy to help fix this.
