Weird version errors compiling darktable

Software darktable
1

I’m trying to compile dt on ubuntu 22.04 with

./build.sh --prefix /opt/darktable/ --build-type Release && sudo git config --global --add safe.directory /home/paolo/git/darktable && sudo cmake --build "/home/paolo/git/darktable/build" --target install -- -j12

I installed gcc 12 and make that it was used:

$ gcc --version
gcc (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0

and I removed the build directory.

However, I keep getting errors like:

CMake Error at cmake/compiler-versions.cmake:43 (message):
  GNU C++ compiler version 11.4.0 is too old and is unsupported.  Version 12+
  is required.
Call Stack (most recent call first):
  CMakeLists.txt:156 (include)

Analogously, my exiv2 has the correct version:

$ exiv2 --version
exiv2 0.27.5

However I get:

CMake Error at cmake/modules/FindExiv2.cmake:45 (message):
  Exiv2 version check failed.  Version was found, at least version 0.25 is
  required
Call Stack (most recent call first):
  src/CMakeLists.txt:428 (find_package)

What am I missing?!?

well, I fixed the first error: it was because I missed g++ 12.

Have you tried ./build.sh --clean-all
?

The error message is produced like this:
message(FATAL_ERROR "Exiv2 version check failed. Version ${Exiv2_PKGCONF_VERSION} was found, at least version ${Exiv2_FIND_VERSION} is required")

Note that it should be Version 1.2.3 was found, but your message Version was found does not include the version number.
Do you have libexiv2-dev installed? exiv2 is just the tool that uses the library; you’ll need the development package for the library to build software using exiv2.

Have you read the README? It provides the following commands to install build dependencies on Ubuntu (copied from the online version; the one you check out with the sources contains Markdown markup):

sed -e '/^#\sdeb-src /s/^# *//;t;d' "/etc/apt/sources.list" \
  | sudo tee /etc/apt/sources.list.d/darktable-sources-tmp.list > /dev/null \
  && (
    sudo apt-get update
    sudo apt-get build-dep darktable
  )
sudo rm /etc/apt/sources.list.d/darktable-sources-tmp.list

right! thank you!

One more problem is that libopenexr-dev in ubuntu 22.04 has a conflict with libimath-dev.

What could I do?

The docs state that OpenEXR package is an optional dependency, however I have it not installed and compiling doesn’t come to an end:

So documentation should be corrected where it says that libopenexr-dev is optional?

I can compile if I install libopenexr-dev which results in uninstalling libimath-dev.
