My log is as follows

I have latest tbb & boost

[fschloesser]

Dear @defencedog,
What are your system specifications?
can you try if the build succeeds with cmake -DCMAKE_INSTALL_PREFIX=$PREFIX/local .. -DLDFLAGS="-llog"?
Best,
Franziska

[defencedog]

@fschloesser Ahh ...Thanks! I am on Andrroid ARM64
Issue is referenced here
Solved via export LDFLAGS="-llog" && cmake -DCMAKE_INSTALL_PREFIX=$PREFIX/local ..

Another question when i did make install why didn't the executables in /bin are moved to local/bin?

[defencedog]

@fschloesser Ok this is above my comprehension skills ...just a chemical engineer man

[fschloesser]

Could you add in CMakeLists.txt at the end of the file

if(TARGET papilo-executable)
   install(TARGETS papilo-executable ARCHIVE DESTINATION bin LIBRARY DESTINATION lib)
endif()

and
to test/CMakeLists.txt after the line target_link_libraries(unit_test papilo ${PAPILOLIB_TARGET} ${Boost_LIBRARIES}) the following

if(${CMAKE_SYSTEM_NAME} STREQUAL "Android")
    target_link_libraries(unit_test log)
endif()

And then in a fresh build directory execute unset LDFLAGS cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX/local and see if the build succeeds please?

[defencedog]

@fschloesser Thanks
After following said instructions one exec is move to local/bin
-- Installing: /data/data/com.termux/files/usr/local/bin/papilo
However in /build/bin there are x2 exec duplicates papilo

[fschloesser]

Perfect. I will add the fix and the patch to the codebase.
Thank you for helping fix this issue!

[defencedog]

@fschloesser but the dublicates exec?

[fschloesser]

Will add the fix. Equivalent to the first addition just need at the end of CMakeLists.txt

if(TARGET duplicates)
   install(TARGETS duplicates ARCHIVE DESTINATION bin LIBRARY DESTINATION lib)
endif()
