Hi,
Any contribution is appreciated. We don't have (yet) any tool to
properly integrate external code and review it. At the moment, we are
working on a solution. Most likely, we will use git branches to merge
external code, but we first have to move our workflow to git.
In the meantime, as you proposed, you may make the code OTB-like. You
can add comments, and even tests.
Regards,
Guillaume

Hi,
You are right... BUILD_SHARED_LIBS was OFF in my ITK cmake config file.
Now it works.
Thanks for your precious comments.
Well. I have written some code lines during my PhD.
I'm starting to clean them and make OTB-like files.
How do you (the OTB team) prefer that I share my codes? Mailing list?
Sandbox?

Hi,
This is odd. I have already managed to compiled OTB on this
platform (Ubuntu 14.04 64bit) with OpenCV.
Have you checked the following details :
- ensure that the Cmake option BUILD_SHARED_LIBS is ON.
- do you reproduce the bug starting from a fresh empty build tree ?
- in the compilation tree, do you managed to compile the target
'OTBApplicationEngine' ?
Regards,
Guillaume

Hi Guillaume,
Thanks for your message.
Indeed I tried to compile all the OTB files with the flag -fPIC.
I added it in CMAKE_CXX_FLAGS and CMAKE_C_FLAGS cmake options.
Unfortunately the error still occur.
Any idea?

Hi,
It seems that your linker can't import a symbol from
libOTBApplicationEngine.a.
As suggested in the error message, you should try compiling
with the flag "-fPIC". Have you tried it ?
Regards,
Guillaume

Hi there,
I would like to install OTB-4.2.1 with OpenCV-2.4.9 but I
get a troubling error during compilation process:
"
Linking CXX shared module
../../bin/otbapp_ComputePolylineFeatureFromImage.so
/usr/bin/ld:
../../bin/libOTBApplicationEngine.a(otbWrapperElevationParametersHandler.cxx.o):
réadressage de R_X86_64_32 en vertu de « .rodata.str1.1 » ne
peut être utilisé lors de la création d'un objet partagé;
recompilez avec -fPIC
../../bin/libOTBApplicationEngine.a: error adding symbols:
Mauvaise valeur
collect2: error: ld returned 1 exit status
make[2]: *** [bin/otbapp_ComputePolylineFeatureFromImage.so]
Erreur 1
make[1]: ***
[Applications/CartographicDBValidation/CMakeFiles/otbapp_ComputePolylineFeatureFromImage.dir/all]
Erreur 2
make: *** [all] Erreur 2
"
This doesn't occur when I set BUILD APPLICATIONS to OFF (but
I need them).
Note that a similar error occurs (i.e. "réadressage de
R_X86_64_32 en vertu de [...]") while compiling Monteverdi.
Please let me know if you know where this error come from
and how to fix it.
Thanks in advance,
Boris
