Still can't get this to build. I get the following error from make -d:

configure: error: could not find a working compiler, see config.log for details

It seems like the autoconf script expects my cross-compiler to emit binaries my host can run which is not possible since it's a compiler targeted at Illumos.

Okay export CFLAGS=-m64 gets past the issue. I had to rerun ./configure ... and then make. I'm running into this error now:

Removing -j $(nproc) fixes the restarting make issue. Build will likely take at least the halflife of cesium now.

Configure mk/build.mk before perl boot. Otherwise it will do a default build.

Create ghc-patches directory beside cross_ghc.sh and put 0001-Include-termios.h-for-solaris2-host.-Fixes-8366.patch in there.

Latest failure log: Further along in the GHC build for SmartOS

Got past the mkGmpDerivedConstants failure by ignoring it, shipping the Solaris binary to a SmartOS box, running that, and restarting make. This is getting more Rube-Goldberg with every revision. A cleaner fix would be a Makefile patch that integrates an instance of the target system into the build process.

Tail of another failed but further GHC cross-build
