Using library with cross-compile toolchain
Giulio89 opened this issue · 3 comments
Hi everyone,
I have just compiled the library on Raspberry PI (native build) without any problem. At the end of the compiling step I have performed a "sudo make install", so the library was copied into /usr/local/lib/libaws-iot-sdk-cpp.so and the include files into /usr/local/include folder.
Now I set up the eclipse in order to cross compile the Shadow sample. I create a sysroot folder on host machine where I copied /usr and /lib folder from Raspberry PI. I created the project where the sorce file are:
- ConfigCommon.ccp, ConfigCommon.hpp
- OpenSSLConnection.cpp, OpenSSLConnection.hpp
- ShadowDelta.cpp, ShadowDelta.hpp
Then I correctly compiled the source code (for all source files) with this command:
arm-linux-gnueabihf-g++ -std=gnu++11 -I/home/rasp/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/arm-linux-gnueabihf/include/c++/4.8.3 -I/home/rasp/raspi/sysroot/usr/include -I/home/rasp/raspi/sysroot/usr/local/include -I/home/rasp/raspi/sysroot/usr/include/arm-linux-gnueabihf -O0 -g3 -Wall -c -fmessage-length=0 --sysroot=/home/rasp/raspi/sysroot -MMD -MP -MF"src/ConfigCommon.d" -MT"src/ConfigCommon.o" -o "src/ConfigCommon.o" "../src/ConfigCommon.cpp"
arm-linux-gnueabihf-g++ -std=gnu++11 -I/home/rasp/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/arm-linux-gnueabihf/include/c++/4.8.3 -I/home/rasp/raspi/sysroot/usr/include -I/home/rasp/raspi/sysroot/usr/local/include -I/home/rasp/raspi/sysroot/usr/include/arm-linux-gnueabihf -O0 -g3 -Wall -c -fmessage-length=0 --sysroot=/home/rasp/raspi/sysroot -MMD -MP -MF"src/OpenSSLConnection.d" -MT"src/OpenSSLConnection.o" -o "src/OpenSSLConnection.o" "../src/OpenSSLConnection.cpp"
arm-linux-gnueabihf-g++ -std=gnu++11 -I/home/rasp/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/arm-linux-gnueabihf/include/c++/4.8.3 -I/home/rasp/raspi/sysroot/usr/include -I/home/rasp/raspi/sysroot/usr/local/include -I/home/rasp/raspi/sysroot/usr/include/arm-linux-gnueabihf -O0 -g3 -Wall -c -fmessage-length=0 --sysroot=/home/rasp/raspi/sysroot -MMD -MP -MF"src/ShadowDelta.d" -MT"src/ShadowDelta.o" -o "src/ShadowDelta.o" "../src/ShadowDelta.cpp"
Then I perform the linking step with the follow command:
arm-linux-gnueabihf-g++ -L/usr/local/lib -L/usr/lib -L/usr/lib/arm-linux-gnueabihf -L/lib/arm-linux-gnueabihf --sysroot=/home/rasp/raspi/sysroot -pthread -o "testAws" ./src/ConfigCommon.o ./src/OpenSSLConnection.o ./src/ShadowDelta.o -laws-iot-sdk-cpp -lcrypto -lssl -ldl
but the result is:

What is the problem?
Thanks a lot!

Hello Giulio,
have to mention that I'm absolute beginner atm but i quess you problem is caused by the stdcxx lib. Have you linked it right?
It also could be a problem if you have different compiler versions (host vs. target) and want to Cross Compile the stdxx lib dynamically. That was my problem when i tried to CC my project for the Beagle Bone Black.

Hello Marco,
thanks a lot for your advise! I changed the compiler version to GCC 6.3.1 so now I'm able to link the std library correctly. Then I had to modify the link command to:
arm-linux-gnueabihf-g++ -L/usr/lib -L/usr/lib/arm-linux-gnueabihf --sysroot=/home/rasp/raspi/sysroot -Wl,-rpath,/home/rasp/raspi/sysroot/usr/local/lib -Wl,-rpath,/home/rasp/raspi/sysroot/lib/arm-linux-gnueabihf -rdynamic /home/rasp/raspi/sysroot/usr/local/lib/libaws-iot-sdk-cpp.so -pthread -o "testAws" ./src/ConfigCommon.o ./src/OpenSSLConnection.o ./src/ShadowDelta.o -lcrypto -lssl -ldl
Now I'm able to compile the sample. But I have a question: I had to add -rpath,/home/rasp/raspi/sysroot/lib/arm-linux-gnueabihf in order to the linker was able to find the libdl.so library. I understand that -rpath option sets the runtime path where the link can find the library. But when I run the executable on Raspberry PI the folder /home/rasp/raspi/sysroot/lib/arm-linux-gnueabihf doesn't exist, but the program runs correctly.
What is the trick?
Thanks a lot!
Giulio
Greetings! Sorry to say but this is a very old issue that is probably not getting as much attention as it deservers. We encourage you to check if this is still an issue in the latest release and if you find that this is still a problem, please feel free to open a new one.
