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:

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

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.

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 acn"checkingforLibdirectory""...ac_n "checking for Lib directory""... acn​"checkingforLibdirectory""...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.

Eventually, your change has to end up in Makefile, right? So I would suggest you start from there: Have configure generate a Makefile, and modify the Makefile so that it suits your needs. If you then don't know how to proceed, please attach both Makefile (the original and the modified one) to this report, and we'll see how to proceed.

Most likely, for your change to show up in Makefile, it would have to appear in Makefile.pre, with likely no changes to configure.in/configure. Makefile.pre, in turn, is generated from Makefile.pre.in, so that your change most likely needs to appear in Makefile.pre.in.

The following patch works for me (derived from davideb's work):

Tres's patch may work, but I think creating a symlink in the build directory named "Lib" pointing to the source Lib directory just masks the real problem. What is the real problem?

I think I may have fixed this in CVS some time ago... (on the release22-maint branch).

Could you find details about the fix? I still get failures when I build Python outside the src directory when there's no Python installation in /usr/local/.

Well, it works for me.

I can't tell you what revision of sysconfig.py I made my fix in, because CVS has just stopped working :-( It was shortly after 222 went out.

I've been told that this has been fixed in distutils for 2.2.3 and 2.3, so I'll close this now.
