我从[{1}}获得了来源，所以它应该可行 - 我在Adacore上也留下了“问题”，但可能需要一些时间来获得解决方案。我怀疑我可能做错了什么，有什么建议吗？
问题在于：
Adacore我可以看到$ gnat make gnatcoll-json.adb
gcc -c gnatcoll-json.adb
gnatcoll-json.adb:33:23: missing body for "Prepend" declared at gnatcoll-json.ads:64

gnatcoll-json.adb:841:28: prefix of dereference must be an access type
gnatmake: "gnatcoll-json.adb" compilation error
文件中的遗漏的正文似乎是第一个问题。例如， Prepend 的主体不在该文件中 - 但我认为正文应该在gnatcoll.ads文件中，而不是gnatcoll.adb档案无论如何。

GNATColl旨在使用相当标准的configure / make / make install流程构建。您可以通过查看分发中的docs/building.rst了解更多信息;我没有用于构建可安装版本的Sphinx program，但它的可读性非常好。还有docs/json.rst告诉您如何在安装GNATColl后使用JSON支持。
在发行版的根目录中，
$ ./configure --prefix=/your/preferred/install/location # default is /usr/local
$ make
$ sudo make install # if /your/preferred/install/location isn't user-writable
