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?
Boris

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
