howdy, Intrigued by the recent discussion of the math library and HAVE_FPU, I defined HAVE_FPU in /etc/make.conf then proceeded to /usr/src/lib/msun, to rebuild the library: (ttyp1@jake)# pwd /usr/src/lib/msun (ttyp1@jake)# make cc -O -D_MULTI_LIBM -D_POSIX_MODE -D_IEEE_LIBM -c /usr/src/lib/msun/src/e_acos. c -o e_acos.o shouldn't it be compiling /usr/src/lib/msun/i387/e_acos.S ??? Oh, well, make does a lot of stuff under the hood, so I proceeded to let it compile, but the resultant library libm.so.2.0, has exactly the same md5 as without HAVE_FPU defined --??? then trying `make -ds e_acos.o', I get amongst other stuff: SuffFindDeps (e_acos.o) trying e_acos.s...not there trying e_acos.S...got it using existing source /usr/src/lib/msun/src/e_acos.c applying .c -> .o to "e_acos.o" looks like it finds e_acos.S, but uses e_acos.c anyway. does anybody else have this problem, or is it a result of one of my local hacks? thanks, eric. -- erich@lodgenet.com http://rrnet.com/~erich erich@rrnet.com
