Bug Report

I download the 6.12 source code in github, and then

sudo PYTHON=/opt/python3.11/bin/python3.11 make -j8 && make install

but erro:

Makefile:5: ../../../src/Makefile.global: No such file or directory
make: *** No rule to make target `../../../src/Makefile.global'.  Stop.

Greenplum version or build

6.12.1

OS version and uname -a

centos7

You need to run ./configure under the root directory of the source code, otherwise the Makefile.global won't exist.

Probably you'll need to use the following command to configure gpdb.

PYTHON=/path/to/your/python3.11 ./configure --prefix=<install_location> ...
make -j8 && make install

then，

PYTHON=/usr/bin/python3.11 ./configure --prefix=/usr/local --disable-gpcloud --without-readline --disable-gpfdist --disable-orca

[higuoxing]

then，

PYTHON=/usr/bin/python3.11 ./configure --prefix=/usr/local --disable-gpcloud --without-readline --disable-gpfdist --disable-orca

Seems that you've solve the problem. Would you please close the issue?

not OK,

[gpadmin@test plpython]$ make

Yes, PL/Python requires Python's dynamic shared library libpython.so. I'm not sure if your system package manager provides it. If it doesn't provide it, you'll need to compile Python yourself.
