Issue installing clas12root on OSX v15.6

[yugotra]

CPU: Apple M3 Max
Memory: 36GB

Tried clas12root 1.8.5 and 1.8.6, same error.
Hipo is from the master branch
root 6.36.04 prebuilt or 6.37.01 (built from source for macosxarm64 on Sep 24 2025 locally), no difference
Xcode 26.0.1

./installC12Root
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.10 will be removed from a future version of
CMake.

Update the VERSION argument value. Or, use the ... syntax
to tell CMake that the project requires at least but has been updated
to work with policies introduced by or earlier.

Thanks for reporting this. It seems to work OK on linux with Root 6.36. The hipo4 classes are not really used anymore, so if you wish to get your code compiled in the meantime, you should be able to remove line 224 of clas12root/CMakeLists.txt :

  add_subdirectory(hipo4)

rm -r build
./installC12Root

Thank you, Derek. After commenting out:

Looks like there is an assumption of the library file name, path, and file extension, for the dependencies CCDB and HIPO. For example:

clas12root/CMakeLists.txt

Line 133 in 37f9eb4

target_link_libraries(clas12::ccdb INTERFACE $ENV{CCDB_HOME}/lib/libccdb.so) # Assumes .so, adjust if needed

[yugotra]

Following the advice from Chris, after replacing "so" with "dylib" in lines 106 and 133, build succeeded.

[dglazier]

Yes, thanks Chris, looks like some hard-wired suffixes have sneaked into the new cmake.

[dglazier]

I made a new branch with automatic lib extension . Yuri , can you check this builds OK for you ? Branch : fix/detect-shared-lib-ext

[yugotra]

Derek, I do not see this branch.

[c-dilks]

Derek, I do not see this branch.

That branch has been merged into master and deleted.

[dglazier]

Correct. Apologies, I wanted the changes in the new release. Yuri you can just pull the changes to master and try that.

[yugotra]

Few issues:

1. hardcoded .so: target_link_libraries(hipo::hipo INTERFACE ${HIPO_INSTALL_DIR}/lib/libhipo4.so)

2 ./installC12Root tries to install in /usr/local/lib
run with custom install dir instead:
./installC12Root -DCMAKE_INSTALL_PREFIX=/Users/gotra/work/c12r/clas12root/install

3. build and install ok, warning on conversion:
   /Users/gotra/work/c12r/clas12root/Clas12Banks/mesonex_trigger.cpp:14:38: warning: implicit conversion from 'double' to 'int' changes value from 0.01 to 0 [-Wliteral-conversion]
   14 | _pcal_cluster_energy_threshold = 0.01; //MeV?

Chris is working on these items.
