#14894: HEAD fails to build with -g1 -------------------------------------+------------------------------------- Reporter: niteria | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.5 Keywords: | Operating System: Unknown/Multiple Architecture: x86_64 | Type of failure: Debugging (amd64) | information is incorrect Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I wanted to see how `-g1` vs `-g2` impact compile speed. Unfortunately I get linking errors trying to build GHC with `-g`. Steps: 1) Add {{{ GhcLibHcOpts += -g1 GhcRtsHcOpts += -g1 }}} to `mk/build.mk`. I used devel2 flavor. 2) `./boot && ./configure && make -j` 3) Observe failure The failure (trimmed): {{{ /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x1c94): error: undefined refe rence to '.LcbG2_info_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x1cc7): error: undefined refe rence to '.LcbGL_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x1cfa): error: undefined refe rence to '.LcbI0_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x1d2d): error: undefined refe rence to '.LcbIh_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x21a4): error: undefined refe rence to '.LcbSn_info_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x21d1): error: undefined refe rence to '.LcbTc_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x234f): error: undefined refe rence to '.Lcc18_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x2c76): error: undefined refe rence to '.Lccmj_info_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x2dff): error: undefined refe rence to '.LccsV_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x2e2f): error: undefined refe rence to '.Lcct6_info_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x2f38): error: undefined refe rence to '.Lccv1_info_die' /data/users/bnitka/ghc-HEAD-dwarf-lint-fixes-g/libraries/base/dist- install/build/libHSbase-4.11.0.0.a(Internals.o)(.debug_info+0x2f66): error: undefined refe rence to '.Lccve_die' }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14894 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
