perl - 为 Raku 构建多个后端失败

Question

阅读后README.md在 https://github.com/rakudo/rakudo特别here ，我冒险为 rakudo 构建多个后端。

我使用 64 位 Ubuntu 20.04 来做到这一点。首先我安装

build essential , libencode-perl

default-jdk为编译 rakudo 准备机器。

克隆 repo 后，当我运行命令时 perl Configure.pl --backends=moar,jvm --prefix=/usr ，我收到以下错误:

如何修复？

我想知道什么 ALL在命令中 perl Configure.pl --backends=ALL指。

有一个项目(我猜仍然在 master 中合并) Rakudo.js here和 here .这是 Javascript 后端吗？
是吗 ALL意味着 moar , jvm和 Javascript后端？

Answer 1

正如@ugexe 所指出的，我失踪了 --gen-moar在我的命令中。

为了将来引用，我想记录我在尝试构建 Rakudo 的反复尝试后学到的东西.

Moar 和 JVM 后端

建筑用moar和 jvm后端您需要依赖项

apt-get install -y gcc \
        libc6-dev \
        libencode-perl \
        wget \
        libzstd-dev \
        default-jdk \
        make

并运行命令

perl Configure.pl --prefix=/usr --gen-moar --backends=moar,jvm --relocatable

用于建筑。构建成功后会得到 rakudo-m , rakudo-gdb-m , rakudo-valgrind-m , rakudo-lldb-m为 moar后端和 rakudo-j , rakudo-debug-j为 jvm后端。

Javascript 和 Moar 后端

您无法构建独立的 javascript 后端。构建时 js后端 you must also build moar .因此，要构建 javascript 后端，要构建的命令将是，

perl Configure.pl --prefix=/usr --gen-moar --backends=moar,js --relocatable

构建的额外依赖项 javascript后端是 nodejs 的可用性, g++和 npm可以通过

apt-get install gcc g++ \
        libc6-dev \
        libencode-perl \
        wget \
        libzstd-dev \
        nodejs \
        npm \
        make

但是在 build 时 javascript后端，我收到以下错误，

'/usr/bin/perl' tools/build/npm-install-or-link.pl . src/vm/js/nqp-runtime nqp-runtime 
Can't exec "npm": No such file or directory at tools/build/npm-install-or-link.pl line 18.
=== SORRY! === `npm install /rakudo/nqp/src/vm/js/nqp-runtime` failed with exit code -1 (72057594037927935)
make: *** [Makefile:852: js-deps] Error 255

Search揭示了

If you are developing nqp-js, you may want to pass the --link option to configure to have the nqp-runtime linked instead of installed

虽然建立隔离没有问题 NQP .我不确定如何在自动构建 rakudo 的同时进行 npm 链接。

所有后端

我了解到 ALL确实是指 moar , jvm和 js后端。这在您运行命令时得到确认

perl Configure.pl --prefix=/usr --gen-moar --backends=ALL --relocatable

您会在终端中看到以下内容:

/usr/bin/perl Configure.pl --prefix=/usr --make-install --git-protocol=https --relocatable --no-ignore-errors --silent-build --no-force-rebuild --backends=moar,jvm,js --gen-moar

这的依赖项将是

apt-get install gcc g++ \
        libc6-dev \
        libencode-perl \
        wget \
        libzstd-dev \
        default-jdk \
        nodejs \
        npm \
        make

如果可以通过解析 npm link成功构建Javascript后端以上问题，我确定所有后端: moar , jvm和 javascript可以建。

所以这里留下的问题是 如何在构建 rakudo 时进行 npm 链接 .希望有人的专家帮助将解决这个问题。
