#15837: Hadrian should build dynamically linked ghc binary -------------------------------------+------------------------------------- Reporter: davide | Owner: davide Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.1 (Hadrian) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D5385 Wiki Page: | Phab:D5327 -------------------------------------+------------------------------------- Comment (by davide): When looking at the output of make I get: {{{ $ find . -name "*ffi*.so*" -or -name "*ffi*.a*" ./libffi/build/x86_64-unknown-linux-gnu/.libs/libffi_convenience.a ./libffi/build/x86_64-unknown-linux-gnu/.libs/libffi.so.7.1.0 ./libffi/build/x86_64-unknown-linux-gnu/.libs/libffi.so.7 ./libffi/build/x86_64-unknown-linux-gnu/.libs/libffi.so ./libffi/build/x86_64-unknown-linux-gnu/.libs/libffi.a ./libffi/build/inst/lib/libffi.so.7.1.0 ./libffi/build/inst/lib/libffi.so.7 ./libffi/build/inst/lib/libffi.so ./libffi/build/inst/lib/libffi.a ./rts/dist/build/libCffi_p.a ./rts/dist/build/libffi.so ./rts/dist/build/libffi.so.7 ./rts/dist/build/libffi.so.7.1.0 ./rts/dist/build/libCffi_l.a ./rts/dist/build/libCffi_debug.a ./rts/dist/build/libCffi_thr.a ./rts/dist/build/libCffi_thr_debug.a ./rts/dist/build/libCffi_thr_l.a ./rts/dist/build/libCffi_thr_p.a ./rts/dist/build/libCffi_thr_debug_p.a ./rts/dist/build/libCffi_debug_p.a ./rts/dist/build/libCffi.a }}} Note that all the `libCffi*.a` files are identical, and all `libCffi*.so` files are identical. == Dynamic This matches closely with my previous comments, but with the addition of some extra versioned .so files. Note the symlinks: {{{ $ ls -l _build/stage1/libffi/build/inst/lib/libffi.so* lrwxrwxrwx 1 david david 15 Dec 6 10:28 _build/stage1/libffi/build/inst/lib/libffi.so -> libffi.so.7.1.0 lrwxrwxrwx 1 david david 15 Dec 6 10:28 _build/stage1/libffi/build/inst/lib/libffi.so.7 -> libffi.so.7.1.0 -rwxr-xr-x 1 david david 70232 Dec 6 10:28 _build/stage1/libffi/build/inst/lib/libffi.so.7.1.0 }}} == Static This matches hadrians behavior w.r.t static libffi. On that grounds I'm going to leave the static libs behavior as is, but add a note about possible simplification here: only copy a single .a file as we will do with the dynamic version. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
