[issue3723] Py_NewInterpreter does not work

[Christian Heimes]

Christian Heimes <lists at cheimes.de> added the comment:

The patch "subinterpreter.patch" is based on Martin's patch
"importexc.diff". The patch contains additional code to setup a
preliminary stderr object and a call to initstdio(). Amaury is right. I
had to add initstdio() to initialize the standard streams. But I can't
get it to work.

$ rm -f Demo/embed/importexc.o; cd Demo/embed; make; ./importexc; cd ../..
gcc -g -I../../Include -I../..  -c -o importexc.o importexc.c
gcc -Xlinker -export-dynamic importexc.o ../../libpython3.0.a  -lnsl
-ldl -lreadline -ltermcap -lieee -lpthread -lutil -lm -o importexc
