This caused an error:
Configuring terminfo-0.3.2.5... configure: WARNING: unrecognized options: --with-compiler, --with-iconv-includes, --with-iconv-libraries, --with-gmp-includes, --with-gmp-libraries, --with-gcc checking for gcc... cc checking whether the C compiler works... no configure: error: in `/usr/home/kazu/work/ghc/libraries/terminfo': configure: error: C compiler cannot create executables
What command was make running when this happened? There should have been a flag like --configure-option=--with-cc="/usr/bin/gcc" where /usr/bin/gcc is the value of CC_STAGE0.
-CC_STAGE0 = @CC_STAGE0@ +CC_STAGE0 = $(CC)
For CC_STAGE0, we deliberately use the C compiler that the bootstrapping GHC uses, not the value of gcc that you specify with --with-gcc. What is @CC_STAGE0@ replaced with in mk/config.mk? And what is the output of /usr/local/bin/ghc --info | grep "C compiler command" (assuming /usr/local/bin/ghc is your bootstrapping compiler)?
