在高山Linux Docker容器中构建GNATCOLL

Question

我似乎不能让GNATCOLL在基于高山Linux的Docker Container中编译。

到目前为止我的容器是：

FROM alpine:edge

# Add extra repositories
RUN echo 'http://dl-cdn.alpinelinux.org/alpine/edge/testing' >> /etc/apk/repositories; \
    echo 'http://dl-cdn.alpinelinux.org/alpine/edge/community' >> /etc/apk/repositories; \
    echo 'http://dl-cdn.alpinelinux.org/alpine/edge/main' >> /etc/apk/repositories;

RUN apk add --no-cache build-base coreutils curl-dev gcc-gnat git gmp-dev openssl

# Bootstrap GPRBuild
RUN git clone https://github.com/AdaCore/xmlada.git; \
    git clone https://github.com/AdaCore/gprbuild.git; \
    cd gprbuild; ./bootstrap.sh --with-xmlada=../xmlada; \
    cd ..; \
    rm -rf xmlada gprbuild

这很好用，并为我提供了一个容器，其中包含一个基于GPR的Ada开发环境。当我尝试在这个容器中安装GNATCOLL时，出现了这个问题。

运行docker run -i -t <built_image>时会发生以下情况：

/ # git clone https://github.com/AdaCore/gnatcoll-core.git
<Typical git clone output>
/ # cd gnatcoll-core/
/gnatcoll-core # make setup
/gnatcoll-core # make
gprbuild -p -m --target=x86_64-linux  -j0 -XGNATCOLL_MMAP=yes -XGNATCOLL_MADVISE=yes -XGNATCOLL_VERSION=0.0 -XGNATCOLL_OS=unix -XBUILD=PROD  -XLIBRARY_TYPE=static -XXMLADA_BUILD=static -XGPR_BUILD=static \
        -XGNATCOLL_MMAP=yes -XGNATCOLL_MADVISE=yes -XGNATCOLL_VERSION=0.0 -XGNATCOLL_OS=unix -XBUILD=PROD gnatcoll.gpr
Setup
   [mkdir]        object directory for project GnatColl
   [mkdir]        library directory for project GnatColl
gnatcoll.gpr:24:06: unknown project file: "gpr"
make: *** [Makefile:128: build-static] Error 4

基于https://github.com/AdaCore/gnatcoll-core/issues/30中的讨论，我检查了我的gprbuild版本：

/gnatcoll-core # gprbuild --version
GPRBUILD Pro 18.0w (19940713) (x86_64-alpine-linux-musl)

因此，musl的gprbuild似乎非常过时，导致无法构建GNATCOLL。有没有办法获得更新版本的gprbuild for musl-c？如果没有，有没有其他方法可以安装GNATCOLL？

问题是gprbuild中的./bootstrap.sh不会安装所有内容，它只是创建了一个最小的gprbuild安装。此外，它不构建gprlib，gprlib是gnatcoll所必需的，也必须安装。

所需的步骤包括：

# As before...
git clone https://github.com/AdaCore/xmlada.git
git clone https://github.com/AdaCore/gprbuild.git
cd gprbuild; ./bootstrap.sh --with-xmlada=../xmlada

# New: build and install xmlada
cd ../xmlada; ./configure && make && make install

# New: build and install gprbuild fully
cd ../gprbuild
export GPR_PROJECT_PATH=/usr/local/share/gpr
make prefix=/usr/local setup && make all && make install

# New: build and install gprlib
make libgpr.build && make libgpr.install

通过这些添加，我能够按照项目中指定的方式构建gnatcoll。
