Hi, Given a package X, let us assume it's a library such that X = unit- threaded, we find that in the ~/.dub/packages directory there is:
.dub/packages/unit-threaded-0.7.51/unit-threaded/gen_ut_main* .dub/packages/unit-threaded-0.7.51/unit-threaded/libunit-threaded.a These are the compilation products from the last undertaken compilation and therefore more or less totally useless for anyone using more than one D compiler. Fortunately we find that there is a .dub directory with: unit-threaded-0.7.51/unit-threaded/.dub ├── build │ ├── gen_ut_main-debug-linux.posix-x86_64-dmd_2081-5610CAAD59972DC7A3346FE37EEC66C8 │ │ ├── gen_ut_main │ │ └── gen_ut_main.o │ ├── gen_ut_main-debug-linux.posix-x86_64-ldc_2081-02C0EA3AA341F3D071FE5E15E09EC021 │ │ └── gen_ut_main │ ├── gen_ut_main-release-linux.posix-x86_64-dmd_2081-A8C2C7980309FFAFE08C15D3B29DE3CC │ │ ├── gen_ut_main │ │ └── gen_ut_main.o │ ├── gen_ut_main-release-linux.posix-x86_64-ldc_2081-78BBAEC37FCFC878CC8215379A7D854B │ │ └── gen_ut_main │ ├── library-debug-linux.posix-x86_64-dmd_2081-5610CAAD59972DC7A3346FE37EEC66C8 │ │ └── libunit-threaded.a │ ├── library-debug-linux.posix-x86_64-ldc_2081-02C0EA3AA341F3D071FE5E15E09EC021 │ │ └── libunit-threaded.a │ ├── library-release-linux.posix-x86_64-dmd_2081-A8C2C7980309FFAFE08C15D3B29DE3CC │ │ └── libunit-threaded.a │ └── library-release-linux.posix-x86_64-ldc_2081-78BBAEC37FCFC878CC8215379A7D854B │ └── libunit-threaded.a └── dub.json OK, so this is now actually useful stuff for people using Dub. Clearly the directory names are dash separated components: · configuration · build type · dot separated platform specification · architecture · underscore separated compiler name and major/minor version number · some bizarre psuedo-random number So the questions are: 1. How does Dub find the compiler version number, in this case 2.081, given that neither DMD or LDC seem to have a way of delivering only the version number. 2. What is the pseudo-random number, and how is it calculated? -- Russel. =========================================== Dr Russel Winder t: +44 20 7585 2200 41 Buckmaster Road m: +44 7770 465 077 London SW11 1EN, UK w: www.russel.org.uk
