Summary: Build error using make VPATH feature
Initial Comment:
PROBLEM DESCRIPTION
=====================
After building successfully Python 2.2.2 from scratch
on Solaris 8 using the usual commands (cd
~wrk/Python-2.2.2; ./configure; make), I decided to
build it for multiple architectures (SunOS 5.6, 5.7 and
5.8), exploiting the supported VPATH feature of GNU make.
Here are the commands I run for Solaris 6:
1. mkdir ~/wrk/Python-2.2.2/binaries/SunOS_5.6
2. cd ~/wrk/Python-2.2.2/binaries/SunOS_5.6
3. ../../configure -prefix=/usr/local/python
4. make
Unfortunately the last command failed with the
following error:...
ranlib libpython2.2.a
gcc -Xlinker --export-dynamic -o python \
Modules/python.o \
libpython2.2.a -lsocket -lnsl -ldl -lpthread -lthread

PROBLEM ANALYSIS==================
By looking the code inside sysconfig.py module, it is
clear that the problem is generated by the first IF
clause (starting at line 32), where the python_build
variable is set: the path obtained by joining "Lib" to
the argv0_path variable does not exist, since no
directory named Lib exists in the (current) work
directory. In fact the only existing directories are:
- Grammar
- Modules
- Objects
- Parser
- Python
- build
WORKAROUND
=============
Simply create a link to the Lib directory provided with
Python 2.2.2, i.e. in my example:
ln -s ../../Lib
make
make test
make install

I'd like to help, but unfortunately I do not know the
autoconf configuration file syntax (i.e. configure.in),
where - I guess - the problem has to be solved.
Yet, by looking at the provided configure script, I added
the following lines (starting at line #7600):
---------------------
echo $ac_n "checking for Lib directory""... $ac_c" 1>&6
echo "configure: checking for Lib
directory" >&5
if test ! -d
Lib; then
ln -s $srcdir/Lib
fi
echo
"$ac_t""done" 1>&6
---------------------
This works fine when using the VPATH feature as well as when
building directly in the standard source directory.

Would you like to work on a patch that fixes this problem?
The patch should support both the case of in-place building,
and VPATH building.
