I tried setting CC in th environment for just the make and it didn't work. I also tried exporting BUILD_CC and wasn't picked up either. Now I just edited the Makefile to set BUILD_CC and it will take about 10 minutes to run. If that works, I'll try setting in configparms. > So I suppose we need to use BUILD_CC=${LFS_TGT}-gcc - AR already > looks ok (at end of config.log) : > S["AR"]="/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/4.7.1/../../../../x86_64-lfs-linux-gnu/bin/ar" > > and CC is of course ok: > S["CC"]="x86_64-lfs-linux-gnu-gcc" > > BUILD_LDFLAGS is not set, so nothing to override for that.
