在Alpine Linux Docker容器中構建GNATCOLL

Question

我似乎無法在基於Alpine Linux的Docker Container中編譯GNATCOLL。

到目前為止我的容器是：

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

這很好用，讓我得到一個容器，其中包含一個基於GNAT GPR的Ada開發環境。 當我嘗試在此容器中安裝GNATCOLL時出現問題。

運行docker run -i -t <built_image>會發生以下情況：

/ # 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

根據https://github.com/AdaCore/gnatcoll-core/issues/30中的討論，我檢查了我的gprbuild版本：

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

因此，看起來muspr的gprbuild已經過時了，導致無法構建GNATCOLL。 有沒有辦法為musl-c獲得更新的gprbuild版本？ 如果沒有，還有其他方法可以安裝GNATCOLL嗎？

問題是./bootstrap.sh中的./bootstrap.sh沒有安裝所有內容，只是創建了一個最小的gprbuild安裝。 此外，它不構建gprlib，這是gnatcoll必需的，也必須安裝。

所需的步驟是：

# 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

通過這些添加，我能夠按照項目中的指定構建gnatcoll。
