New submission from Mark Dickinson: With the current ./configure setup, it looks to me as though there are no circumstances under which the file Python/hypot.c is compliled. There's a line
AC_REPLACE_FUNCS(hypot) in configure.in; which is supposed (if I understand correctly) to check for a system hypot(), and use the replacement file hypot.c if the system hypot() isn't found; but the mechanism for using the replacement file seems not to work: I tried the following: (1) replace all occurrences of hypot with myhypot in configure.in, pyport.h, complexobject.c, mathmodule.c and cmathmodule.c. (2) move Python/hypot.c to Python/myhypot.c, and rename the function contained within from hypot to myhypot (3) rerun autoconf and autoheader (4) ./configure && make The result: as expected, during configuration I got: checking for myhypot... no but building failed with: ar cr libpython2.6.a Objects/abstract.o Objects/boolobject.o Objects/ bufferobject.o Objects/cellobject.o Objects/classobject.o Objects/ cobject.o Objects/codeobject.o Objects/complexobject.o Objects/ descrobject.o Objects/enumobject.o Objects/exceptions.o Objects/ genobject.o Objects/fileobject.o Objects/floatobject.o Objects/ frameobject.o Objects/funcobject.o Objects/intobject.o Objects/ iterobject.o Objects/listobject.o Objects/longobject.o Objects/ dictobject.o Objects/methodobject.o Objects/moduleobject.o Objects/ object.o Objects/obmalloc.o Objects/rangeobject.o Objects/setobject.o Objects/sliceobject.o Objects/stringobject.o Objects/structseq.o Objects/tupleobject.o Objects/typeobject.o Objects/weakrefobject.o Objects/unicodeobject.o Objects/unicodectype.o ar cr libpython2.6.a Python/Python-ast.o Python/asdl.o Python/ast.o Python/bltinmodule.o Python/ceval.o Python/compile.o Python/codecs.o Python/errors.o Python/frozen.o Python/frozenmain.o Python/future.o Python/getargs.o Python/getcompiler.o Python/getcopyright.o Python/ getmtime.o Python/getplatform.o Python/getversion.o Python/graminit.o Python/import.o Python/importdl.o Python/marshal.o Python/modsupport.o Python/mystrtoul.o Python/mysnprintf.o Python/peephole.o Python/ pyarena.o Python/pyfpe.o Python/pystate.o Python/pythonrun.o Python/ structmember.o Python/symtable.o Python/sysmodule.o Python/traceback.o Python/getopt.o Python/pystrtod.o Python/dynload_shlib.o Python/ mactoolboxglue.o Python/thread.o ar cr libpython2.6.a Modules/config.o Modules/getpath.o Modules/main.o Modules/gcmodule.o ar cr libpython2.6.a Modules/threadmodule.o Modules/signalmodule.o Modules/posixmodule.o Modules/errnomodule.o Modules/pwdmodule.o Modules/_sre.o Modules/_codecsmodule.o Modules/zipimport.o Modules/ symtablemodule.o Modules/xxsubtype.o ranlib libpython2.6.a gcc -L/opt/local/lib -u _PyMac_Error -o python.exe \ Modules/python.o \ libpython2.6.a -ldl /usr/bin/ld: Undefined symbols: _myhypot (I'd like to know how to fix this: I've been working on fixing some of the numerical problems in the cmath module, and hoped to imitate the hypot setup for the functions log1p, asinh and copysign.) ---------- components: Build messages: 57350 nosy: marketdickinson severity: minor status: open title: Python/hypot.c is never used versions: Python 2.5, Python 2.6 __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1418> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
