This is such a noddy question, but I'm struggling to particularly install libadalang which (to avoid X-Y problem) came from me having a working Gnatstudio, installing ada webserver, then I couldn't start Gnatstudio as it required libadalang.so. So I tried to install libadalang and
am currently getting failures of the form
libadalang-iterators-extensions.ads:29:29: file "langkit_support-symbols-precomputed.ads" not found
So I've spammed my /opt/GNAT/2020 with installing langkit everywhere that looks likely.
./lib/langkit_support
./lib/lib/langkit_support
./lib/include/langkit_support
./include/langkit_support
And still the installer for libadalang doesn't work.
Clearly something going on with paths here that I'm not getting. Can anyone provide any information on how paths are supposed to work as I need to install a number of other ada and SPARK-ada libraries from github and I want to do it correctly.
I think, the simplest way to restore GNAT Studio is to delete everything and reinstall. The GNAT Studio has its-own copy of libadalang/langkit. Look for
<install-path>/lib/gnatstudio/libadalang.so
<install-path>/lib/gnatstudio/liblangkit_support.so
When you install a developer version of libadalang you will get another copy of these files. They could have a different version.
I would suggest you to install GNAT Studio into a dedicated directory and make sure you launch it with a shell script from the bin (bin/gnatstudio). This way it shouldn't be affected by any other installed libraries.
Installing AWS shouldn't break GNAT Studio installation. If you know how to reproduce, please report to AdaCore.
