I have an Ada library project creating a shared library that has dependencies on other prebuilt shared libraries (c/c++). Unfortunately the prebuilt libraries can’t be installed system wide and I am looking for a project setup without user specific library path’s.

Therefor I want to create a GPR project that “configures/installs” the Ada library and its dependencies with ‘gprinstall’ so the Ada library can be use out-of-the-box in any Ada executable project.

I figured out that I can make a separate “externally_built” Ada library project for every dependency there is and run a recursive gprinstall on the Ada library project. This will work but adds more packages to the Ada environment than I like so I want to know if there is a better/elegant way to include (extra) shared libraries in a Ada project? (1)

Form the Ada (library) project standpoint the external built libraries kinda belong together, so it would be great if they can be bundled together in one package and installed with gprinstall.

Although I am not sure if this is the way to go, I am trying to get the externally built libraries to piggy-bag with the gprinstall of the Ada library project but without success, maybe someone has an idea how to do this? (2) It’s seems gprbuild can only output one object, is this so? (3)

Thanks in advance and for your time, Ingmar

I'm recieving the error error: No index.toml file found in index when I'm trying to use alr get gnat_native and alr get gprbuild on Debian. I made sure that Alire is installed, by using the 'alr' command I get 'alr 1.2.2' when I do the command.

I expected to download the Alire tools, and not to recieve a error when I do alr get gnat_native and `alr get gprbuild'. I made sure that Alire is installed, by using the 'alr' command I get 'alr 1.2.2' when I do the command.

I'm dealing with huge global lists in Ada. When building I'm getting the error during linking: relocation truncated to fit R_X86_64_PC32 and link of main.adb failed. I saw that GCC has the flag -mcmodel=medium, is there something similar for gprbuild or does anyone has a hint how to deal with huge global lists?

Thanks in advance.
