Hi Sergei, I see some host <-> target confusion here. It is probably caused by https://github.com/ghc/ghc/blob/master/rules/build-package-data.mk#L74 I have always built my cross-ghc with this patch: ifeq "$$(CrossCompiling)" "YES" $1_$2_CONFIGURE_OPTS += --configure-option=--host=$(HOSTPLATFORM) $1_$2_CONFIGURE_OPTS += --configure-option=--target=$(TARGETPLATFORM) endif instead, and have not seen problems so far. Maybe we should specify how the packages should be configured for different stages of the compiler once and for all, so we do not perpetuate the current confusion. Cheers, Gabor

Hi Sergei,

I see some host <-> target confusion here. It is probably caused by

https://github.com/ghc/ghc/blob/master/rules/build-package-data.mk#L74

I have always built my cross-ghc with this patch:

ifeq "$$(CrossCompiling)" "YES" $1_$2_CONFIGURE_OPTS += --configure-option=--host=$(HOSTPLATFORM) $1_$2_CONFIGURE_OPTS += --configure-option=--target=$(TARGETPLATFORM) endif

Setting --host is correct (and is already done by the build system), but passing --target to the configure script for a library would be wrong. Cheers, Simon
