Honestly I'm not sure if what Dyson does here is the correct thing or not. I'll try to merge your patches here and test on real Solaris 11 and see if breaks anything or not. Still if you are Dyson developer I would appreciate some in-depth info why you use libs this way, i.e. why you attempt to define libdl/librt as linker scripts instead of simply omitting them...

The patch make GHC only check whether we need libdl or libpthread. If not it will not load them. On Solaris libdl is a filter library. It exists only for backward compatibility. dlopen() function really is not even in libc, but in runtime linker ld.so. As for Dyson hack: I use GNU binutils. I had linker (GNU ld) problems when linking filter libraries, e. g. symbols versions mismach or so, can't remember. In come cases I was not able to link libpthread.so or librt.so. But on Solaris, illumos and Dyson I don't need to, because all functions are in libc (ld.so) Unfortunately, many (== almost all ;-) packages does not check whether they need these libraries, some of packages link them unconditionally, e. g. gcc -ldl -lpthread, etc. So instead of using real symlinks like libdl.so -> libdl.so.1, I made libdl.so be a file with [GNU] linker script with does nothing. Thus every package is happy finding these libs, and I don't have linking errors. In the ideal world GHC should load real library, not a developer symlink, e. i. libdl.so.1 instead of just libdl.so. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8713#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I'm looking into it and I'm curious if it may be solved by other way. Please what's OS is exactly detected by {{{ $ sh config.guess }}} I'm curious since if it is Solaris than this should be improved to handle Dyson specifically since I think Solaris kernel + GNU libc is not Solaris anymore. And if it is not Solaris than at least patch to DriverPipeline.hs may be done in a little bit more clean way. I don't like using this #ifdef in parameters list construction. If you add proper support for OSDyson, then you can add OSDyson *BSDs, Darwin etc. and be done with this bit in more clean way IMHO. But well, the crucial question is how the OS is identified by config.guess...BTW: generally speaking I hope I'm right here but GHC devs tries to get rid of platform configuration related #ifdefs in the code and use proper Haskell handling of this.
