Just to follow-up on my earlier emails about trying to port GHC to a uClibc-based Linux, I finally did get this working, on both x86 and x86_64. There were a bunch of small stumbling blocks and one big one that I finally traced to the fact that the native gcc on my target system had the Gentoo hardening patches, and one needed to supply a "-nopie" option to selectively disable these. (This was counter-intuitive because the error messages made it seem that what was wanted was to *enable* PIE compiling, not to disable it.) I finally identified this issue when reading http://www.gentoo.org/proj/en/hardened/hardenedfaq.xml. Anyway, I've written up what it took to port GHC to our system on our distro's wiki: http://wiki.alpinelinux.org/wiki/Porting_GHC_to_Alpine Perhaps that might help others attempting similar feats, or might help the ghc devs working on the build system to make this less painful in the future. -- dubiousjim@gmail.com
