Hi,
I changed the .config to use "toolchain/uClibc/uClibc-0.9.32.config" (I only
touched this thing), did make clean, and git pull.The compilation ends in the
same place with the same effect (small unrelated differences - I can submit if
you want).
I looked at the two defconfigs - both have # UCLIBC_HAS_FENV is not set.
I also noticed this patch:
toolchain/uClibc/uClibc-0.9.32-honor-UCLIBC_HAS_FENV-for-e500.patch, but sadly
I don't understand if it has anything in common.
Regards, Jacek
grep ^BR2_UCLIBC .config
BR2_UCLIBC_VERSION_0_9_32=y
BR2_UCLIBC_VERSION_STRING="0.9.32"
BR2_UCLIBC_CONFIG="toolchain/uClibc/uClibc-0.9.32.config"
