3.9. Q. I use VPATH but some targets are built in the source directory.

A. On some systems (e.g. Sun), if the target already exists in the

source directory, it is created there instead of in the build

directory. This is usually because you have previously built without

A. The problem seems to be that that the NeXT posix library and the

NeXT dynamic loading library are incompatible. Mike Carlton reports

that the following worked for him (from a clean 1.1 distribution):
|

1) ./configure

2) edited config.status and changed

OPT='-O'
|

to
|
||||
OPT='-posix -O'
|

3) edited Python/import.c and commented out the section

#if defined(NeXT) || defined(WITH_RLD)

#define DYNAMIC_LINK

#define USE_RLD
