Updated abseil-cpp introduced some breaking changes regarding VLOG_IS_ON. If you are getting errors in building you needs to edit the PKGBUILD and add

prepare() {
  cd "$srcdir/or-tools-$pkgver"
  sed -i '23i#include "absl/log/vlog_is_on.h"' ortools/base/logging.h
}

And a new failure with gcc 14.2.1 and abseil-cpp 20240722.0-1

Maybe it makes sense to bundle the dependencies?

Doesn't build with gcc 14.1.1

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find GTest (missing: GTEST_LIBRARY GTEST_INCLUDE_DIR
  GTEST_MAIN_LIBRARY)

I didn't have extra/gtest installed.

After installing it, it compiled successfully.

for re2 only the pkgconfig is installed
ref: https://archlinux.org/packages/extra/x86_64/re2/ so we have a custom FindRe2.cmake to find it
https://github.com/google/or-tools/blob/main/cmake/Findre2.cmake you may try to add it in your CMAKE_PREFIX_PATH in order to find re2
On my way to debug it...

I'm trying to use or-tools in a CMake project with

find_package(ortools CONFIG REQUIRED)

but I get the error

/usr/lib/cmake/ortools/ortoolsTargets.cmake:85: error: The link interface of target "ortools::ortools" contains: PkgConfig::re2 but the target was not found.  
Possible reasons include: 
* There is a typo in the target name. 
* A find_package call is missing for an IMPORTED target. 
* An ALIAS target is missing. /usr/lib/cmake/ortools/ortoolsConfig.cmake:98 (include) CMakeLists.txt:24 (find_package)

Any idea what might be going on? re2 is installed.

edit: I had to add the following lines before find_package(ortools CONFIG REQUIRED):

find_package(PkgConfig REQUIRED)
pkg_check_modules(RE2 REQUIRED IMPORTED_TARGET re2)
pkg_check_modules(CBC REQUIRED IMPORTED_TARGET cbc)

Hi, the package is building in clean chroot and Eigen is specified as dependency so likely you are not building the package with all dependencies.

Hello, I keep getting this

Thanks for the tips!

since you are using -DBUILD_EXAMPLES=OFF, then -DBUILD_CXX_EXAMPLES=OFF is not needed ref: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=or-tools#n28 see: https://github.com/google/or-tools/blob/fa84bc05e72641dddfbb98164d81b8bc9bef6ea5/CMakeLists.txt#L129
