I'm sending this patch a couple of days earlier than anticipated. The new file, ada-libgnatprj.dpatch, continues the trend started in ada-link-lib.dpatch and ada-libgnatvsn.dpatch. It introduces a new shared libary, named libgnatprj wirh soname libgnatprj.so.4.1. libgnatprj contains the GNAT Project Manager, i.e. the parts of the GNAT tools that parse and process GNAT project files (*.gpr). This new library relies on libgnatvsn, and is linked against it. The new .dpatch file then links the GNAT tools dynamically against all three libraries (libgnat-4.1, libgnatvsn and libgnatprj). Finally, it creates two new binary packages, libgnatprj-dev and libgnatprj4.1. Here are some numbers I collected over the past couple of weeks; these are the sizes of the GNAT tools, in bytes, on i386, after stripping. tool static libgnat libgnatvsn libgnatprj ----------------------------------------------------------- gnat 922.544 773.104 732.264 162.724 gnatbind 767.384 658.820 357.500 156.244 gnatbl 18.144 18.148 9.784 6.964 gnatchop 269.264 113.928 57.972 58.332 gnatclean 891.216 771.760 729.384 95.208 gnatfind 430.864 255.280 201.240 119.904 gnatkr 86.128 76.536 10.284 10.620 gnatlink 313.960 288.840 225.468 73.684 gnatls 826.032 774.432 252.648 48.216 gnatmake 1.535.016 1.416.416 1.048.136 370.936 gnatname 755.120 577.584 497.864 78.524 gnatprep 530.064 351.352 221.724 91.124 gnatxref 430.864 255.120 200.344 118.528 gprmake 983.824 767.472 716.200 142.044 TOTAL 8.760.424 7.098.792 5.260.812 1.533.052 Change -1.661.632 -1.837.980 -3.727.760 Change% -19% -26% -71% Cumulated change% -40% -83% Shared library size: 2.415.060 905.044 1.012.296 The GNAT tools alone benefit greatly from dynamic linking. Moreover, I have crafted libgnatvsn and libgnatprj in such a way that I can now reuse them in ASIS, GLADE and GPS (ASIS only needs libgnatvsn; GPS needs both libgnatvsn and libgnatprj). libgnatvsn contains code licensed under the GNAT-Modified GPL; if you link a program against it, you can distribute the resulting binary under whatever licencing terms you please. In contrast, libgnatprj is licensed under the pure GPL, so if you link a program to it, you must distribute the resulting binaries under the GPL, or in source-form only, or keep them to yourself. With this patch, I have now ported all my changes from gnat 3.15p. Before I make gcc-4.1 the new default Ada compiler for Debian, there are still a couple of issues that I'll work on in the near future: * avoid patching configure, call autoconf instead (per request from Matthias Klose). This applies to ada-link-lib.dpatch, ada-libgnatvsn.dpatch and ada-libgnatprj.dpatch. (We will continue to patch Makefile.in instead of running autogen). * Patch the test suite (src/gcc/testsuite/ada/acats/run_acats) to find the GNAT tools in their new home (build/gnattools instead of build/gcc), and to find the needed shared libraries. * Support biarch. I'll need much help, and new hardware for this. Biarch is one of the three main benefits of the move to gcc-4.1 (the other two are uniarch support for more architectures, and Ada 2005 features). I will appreciate any and all feedback. -- Ludovic Brenta.
