Unable to compile on Xenomai target¿?

Submitted by enkulator on Fri, 2011-10-21 08:26

Dear developers.

I develop a component in my desktop environment ( ubuntu 10.04 + gnulinux as target on Orocos 2.4.0 installation). All is fine on it.

But later,when I get the source project of my component and transfer it to my embedded platform (Debian 6.0.2 with Xenomai target on Orocos 2.4.0), the linker compilation crashed:

Linking CXX shared library libmydriver-xenomai.so
/usr/bin/ld: cannot find -llog4cpp
collect2: ld returned 1 exit status
make[2]: ***[libmydriver-xenomai.so] Error 1
make[1]: ***[CMakeFiles/ ... Error 2
make: *** [all] Error 2

I have references on log4cpp and dependencies on my CMakeList.txt

[...]
orocos_use_package(ocl-logging)
[...]
target_link_libraries(mydriver log4cpp)
[...]

Any ideas¿? Thanks in advance Toni

Try: orocos_use_package( log4cpp )
instead of the target_link_libraries. It can't find 'log4cpp' because you
didn't specify an absolute path.
