The reason for the above was probably that something was cached; got exactly the same problem when tried in debian:11 (podman) container w/o libpython3-dev (*) -- and after apt-get install libpython3-dev the above cffi.FFI().verify() worked Tomi (*) executed the following on top of docker.io/library/debian:11 and then ./configure in notmuch source dir... export DEBIAN_FRONTEND=noninteractive apt-get update apt-get install -y -q build-essential emacs-nox gdb git man \ dtach libxapian-dev libgmime-3.0-dev libtalloc-dev \ python3-sphinx python3-cffi python3-pytest \ python3-setuptools gpgsm parallel apt-get -y autoremove apt-get -y clean rm -rf /var/lib/apt/lists/ > >> >> cheers, >> >> d > > Tomi ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org

In case of python3-devel missing in Fedora, the compilation should not pass as far as shown in David's email (and in log below) as it is needed for Checking for python3 cffi and setuptools... configure part to complete with 'Yes' But the message could be better. Perhaps Checking for python3 dev(el), cffi and setuptools... (although this may not be clear enough for debian users as the package there is libpython3-dev, cannot say...) For me, to figure out what was needed in Fedora 34 (ok, 33, but now tested in upgraded fedora 34 host in running fedora:34 podman container) was to run script -c 'sh -x ./configure'; less typescript; and then do internet search how to install missing 'Python.h' include file...

You need python3-cffi to run python code which uses cffi bindings - think of it as the "lib" part. You need the devel package to generate a python module using cffi (i.e. binding for a specific c library). So, it makes sense for the lib package not to depend on the devel package (which is python3-devel on Fedora). I can't help with adapting configure to the header requirement, though.

configure checks for python3-notmuch2 module
It turns out we need pyconfig.h to build the (new) python bindings. I don't think this is adequately checked for by the configure script, since I had a Fedora user report a build failure (during make install, which I found odd) missing pyconfig.h On Debian this is on libpython3.x-dev, which is not a dependency of the python3-cffi package. log follows. -- cd bindings/python-cffi && \ python3 setup.py build --build-lib build/stage && \ mkdir -p build/stage/tests && cp tests/*.py build/stage/tests running build running build_py running build_ext generating cffi module 'build/temp.linux-x86_64-3.9/notmuch2._capi.c' creating build/temp.linux-x86_64-3.9 building 'notmuch2._capi' extension creating build/temp.linux-x86_64-3.9/build creating build/temp.linux-x86_64-3.9/build/temp.linux-x86_64-3.9 gcc -pthread -Wno-unused-result -Wsign-compare -DDYNAMIC_ANNOTATIONS_ENABLED=1 -DNDEBUG -O2 -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -D_GNU_SOURCE -fPIC -fwrapv -O2 -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -D_GNU_SOURCE -fPIC -fwrapv -O2 -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -D_GNU_SOURCE -fPIC -fwrapv -fPIC -I../../lib -I/usr/include/python3.9 -c build/temp.linux-x86_64-3.9/notmuch2._capi.c -o bui ld/temp.linux-x86_64-3.9/build/temp.linux-x86_64-3.9/notmuch2._capi.o build/temp.linux-x86_64-3.9/notmuch2._capi.c:50:14: fatal error: pyconfig.h: No such file or directory 50 | #include | ^~~~ compilation terminated. error: command '/usr/bin/gcc' failed with exit code 1 ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org
