ghc-7.4.2 on sparc solaris without threaded rts

[maeder]

my build of ghc-7.4.2 could not link binaries compiled with "-threaded" ("ld: library -lHSrts_thr: not found"). In fact RTS ways does not include "thr" entries as was the case for ghc-7.0.4. Why?

I'm on solaris 10 "SunOS 5.10 Generic_147440-21 sun4u sparc SUNW,Sun-Fire-280R", gcc-4.6.3, and ld: Software Generation Utilities - Solaris Link Editors: 5.10-1.1510

The threaded RTS is built unconditionally, to disable it you would have to do this manually. How did you build GHC?

[maeder]

gmake after fixing DriverPipeline?

next and final log

[maeder]

as always:

-bash-3.00$ cat mk/build.mk
BIN_DIST=1
Project=Ghc
XMLDocWays = html
HADDOCK_DOCS = YES

In addition I've removed the [SysTools?.Option "-Wl,-no-relax"] in compiler/main/DriverPipeline.hs after "ld: unrecognized option '-n'" (see #5407)

I had to continue "gmake" several times. I'll attach the last two logs.

Replying to maeder:

as always: {{{ -bash-3.00$ cat mk/build.mk BIN_DIST=1 Project=Ghc XMLDocWays = html HADDOCK_DOCS = YES }}}

Except for HADDOCK_DOCS those are all settings for the old build system and won't have any effect. Also HADDOCK_DOCS defaults to YES anyway, so you're effectively compiling with an empty build.mk :-)

I think I see why you don't have the threaded RTS:

GhcRTSWays += $(if $(findstring NO, $(GhcUnregisterised)),thr thr_debug thr_l,)

this is different in the 7.4 branch: I made the threaded RTS unconditional after 7.4.

Sparc is unregisterised now that the registerised C backend has been removed, which is why you're not getting the threaded RTS. You can enable the threaded RTS explicitly by adding GhcRTSWays += thr to your mk/build.mk.

In addition I've removed the [SysTools?.Option "-Wl,-no-relax"] in compiler/main/DriverPipeline.hs after "ld: unrecognized option '-n'" (see #5407) I had to continue "gmake" several times. I'll attach the last two logs.

[maeder]

Ok, I'll try again with extended RTSways.

Do I not need to set BIN_DIST=1 in build.mk in order to create a binary distribution? Can I omit build.mk entirely in future builds?

Yes, and yes.

[maeder]

thanks, meanwhile I've succeeded in creating a working ghc with threaded rts.
