Thanks for the help. You may have unexpected results. That warning occurs because some of glibc (namely, the getaddrinfo bit) is dynamically linked regardless of what you want; this is apparently to make NSS work, or something along those lines. However, if you then link the rest of glibc statically, you get dependencies between your program and the installed glibc, for internal, unstable APIs. (!) This is generally a Big No. Doing this means your program definitely won't be compatible with older versions of glibc, but it probably wouldn't be either way.

I always get the same error. Does somebody know how to correctly specify the pthread library for this? Hi, Try: ghc --make Installer.hs -static -optl-static -optl-pthread If that doesn't work, you can always do a ghc -v, find the command it uses for linking, modify it and run it manually. Thanks!

[Haskell-cafe] static linking failure -- can't find crt0
I'm building a really static executable on OS X with options `-optl-static -static` and, while the libraries seem to link fine, the executable itself does not -- it can't find the C runtime. This is actually by design -- Apple does not support static binaries. There is a work around -- just symlink stuff till the errors go away -- but it might be better if I could statically link only those C libraries that I knew were not on stock Macs. Are there GHC options for that? I assume this all works fine on Linux and Windows, but I'll know soon enough... -- _jsn |...can't find the C runtime.| ld_classic: can't locate file for: -lcrt0.o collect2: ld returned 1 exit status |does not support| http://developer.apple.com/qa/qa2001/qa1118.html ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
