[Log4cplus-devel] Failed to compile using cmake android toolchain

From: Vladimir \Equidamoid\ S. <equ...@gm...> - 2013-08-12 17:13:48

Hello,

I'm trying to build log4cplus for android using cmake (added 
'add_subdirectory(path/to/the/source)' to my main CMakeLists.txt).
The build crashes with the following error:
[ 48%] Building CXX object 
jni/lib/log4cplus-1.1.1/src/CMakeFiles/log4cplus.dir/global-init.cxx.o
jni/lib/log4cplus-1.1.1/src/global-init.cxx:268:46: error: 
log4cplus::internal::__emutls_t._ZN9log4cplus8internal3ptdE causes a 
section type conflict with log4cplus::internal::ptd
jni/lib/log4cplus-1.1.1/src/global-init.cxx:268:46: note: 
'log4cplus::internal::ptd' was declared here

Is this a bug or I'm doing something wrong?


Best regards,
Vladimir

This looks like a deficiency in the Android tool chain. The only problem
with log4cplus is probably that its CMake scripts do not detect that the
tool chain is lacking this feature.

I am adding Nikita Manovich to CC because he is the one who has
contributed the Android port patches.

It seems that the error is caused by -fdata-sections flag set by 
android.toolchain.cmake (line 930).
I don't actually understand why that flag is needed there but addng


if (ANDROID)

     add_definitions(-fno-data-sections)

endif(ANDROID)


to log4cplus/src/CMakeLists.txt fixes the issue.

I am glad that you found a work around for this issue.

I have updated the android.toolchain.cmake file from the OpenCV
repository at <http://code.opencv.org/projects/opencv/repository/revisions/master/changes/platforms/android/android.toolchain.cmake>.
However the updated file still contains the offending -fdata-sections
flag. I think that we (I actually mean you :) should do two things:

1. document the issue and your workaround in README;
2. complain to Google (fill a bug report) that their NDK
compiler/toolchain does not properly support thread local storage.

Hi,

I will look at the problem this week. Probably I will find a solution and
send a patch if it is necessary.
