commit r17-723-g6cd854ea878c44ba8b96fede81a95ff6a8e97b65 Author: Sebastian Poeplau <[email protected]> Date: Fri Nov 14 16:46:21 2025 +0100 ada: Extend the runtime GPR files for shared libs The GPR files can be used to build the Ada runtime, usually via libada.gpr as the entry point. This commits extends the GPR project definitions to make them suitable for shared and static PIC runtime builds. When LIBRARY_KIND is "static-pic", the libraries gain a "_pic" suffix, as expected by the build tools. When it's "dynamic", we configure the Library_Version attribute in order to set the right SONAME on Unix, as well as the expected symlinks. Finally, libgnarl.gpr now depends on libgnat.gpr; the missing dependency hasn't caused problems so far because static libraries don't resolve missing symbols at build time, but it's necessary to build shared libraries. gcc/ada/ChangeLog: * libgnarl/libgnarl.gpr: Add dependency on libgnat.gpr. Set Library_Name and Library_Version depending on Library_Kind. * libgnat/libgnat.gpr: Likewise.
