CentOS 8 compilation - fatal error: Imaging.h: No such file or directory

[BenKennish]

I followed the instructions to compile from source on CentOS 8 (as there are no CentOS 8 RPMs available yet - see #1677 ) and I get the following...

I did a bit of digging and it seems that Imaging.h is a PIL header file but the python3-pillow package doesn't seem to install any header files. Am I on the right track? I did a yum "whatprovides" search for Imaging.h and can't find any packages that provide it.

Thanks in advance for any advice 🙂

Try installing python3-pillow-devel also, I believe that should provide Imaging.h

[BenKennish]

Doesn't appear to be available...

Apologies, the description of the python3-pillow package suggested to me that python3-pillow-devel existed, but that doesn't appear to be the case!

Doubt this is an ideal method, however I've managed to get it building on CentOS 8.1.1911 by using the below commands to download the source of the python3-pillow package & extract into a directory, following which the specific directory containing Imaging.h can be included during compilation (assuming the present working directory is that containing setup.py):

yum install yum-utils
export tmpPillow=$(mktemp -d)
pushd $tmpPillow
yumdownloader --source python-pillow
rpm2cpio python-pillow-*.src.rpm | cpio -idmv
tar xf Pillow-*.tar.gz
popd
CPPFLAGS='-I'$(readlink -f ${tmpPillow}/Pillow-*/src/libImaging) python3 setup.py build
rm -r $tmpPillow
unset tmpPillow

Sorry for taking so long to get back to you. Your instructions worked a treat, the build completed successfully and it's rendering now! 😁

I've mentioned the absence of the devel package to RedHat: https://bugzilla.redhat.com/show_bug.cgi?id=1993690

[DarkArc]

Interestingly enough the spec file already contains the spec for the relevant devel package. Here are some alternative instructions that will integrate with the package manger:

First setup rpm-build

sudo dnf install rpm-build redhat-rpm-config rpmdevtools
sudo useradd --no-create-home --system mockbuild
sudo groupadd mock
rpmdev-setuptree

Then build the actual packages(dist .el8_2 might need changed base this off the Release field of dnf info python3-pillow):

sudo dnf builddep python-pillow
dnf download --source python3-pillow
rpmbuild --rebuild --define 'dist .el8_2' python-pillow-*

The new packages (including the devel package) will be available at:

~/rpmbuild/RPMS/x86_64

If using auter and not actively monitoring the server, I'd strongly advise adding either PACKAGEMANAGEROPTIONS="--nobest" or PACKAGEMANAGEROPTIONS="--allowerasing".

--nobest should ensure auter can still download and apply updates even if a new version of python-pillow ships -- python pillow will just be held/back skipped.

Likewise --allowerasing will allow auter to simply remove the broken devel package and move python-pillow forward. (This is potentially a more dangerous option in the sense that it could result in auter breaking the system.

Perhaps best is simply removing the devel pacakge after building :)
