Seems in 2019 ARM (32-bit) support moved to -mfloat-abi=hard (unless you built your own system?) But, in the postings I've stumbled over there was mention of /libsoft and /usr/libsoft. But - in my recent FreeBSD-13.2 install I don't see those. Has this gone away? Is there no way to build a program with -mfloat-abi=soft and link with the math library (-lm)? - Thanks - - Dave R. - -- rivers@dignus.com Work: (919) 676-0847 Get your mainframe programming tools at http://www.dignus.com
