Linking Problem with libdart.so on ubuntu 15.10 #695
Comments

It seems the linker fails to find proper libraries, but I honestly don't know much about using compiler and linker. I instead use CMake to build things. If you willing to use CMake for your project, then could you take a look at this example and this patch if it's useful to you? |

Thank you @jslee02 I've tried the example. I get the following error message. So maybe the problems are
It seems that the error comes from the setting of the compiler P.S. I get the similar undefined reference even on Mac (OSX El Captain) Is there any settings I should add? Or there's other problem? |

Quick question: Did you install DART 5.1 with this patch? |
|
Silly question: How could I install the patch? Should I remove first, download, and install it again? |
|
If you installed DART from the dart ppa, then you should remove it first as: sudo apt-get remove libdart5-dev
sudo apt-get remove libdart-core5-devOr, if you installed DART from the source, then you don't need to remove it. It will be overwritten when you install a new one. A quick way to test the example would be:

Thank you for you zip with patch. However, I run into series of error of nplot and osgDart support while building DART Should I remove the optional support for DART first? |
|
I solved it by reboot the virtual machine to make sure there's enough swap space. And I built DART with the patch again. The patch works fine and the example you gave runs well. Thank you very much! |

Great! Once #698 is merged, you can use the patched version of DART from the PPA back. |
Dear all,
This is my first time to use DART sim and I have some problem while testing my own code.
I've successfully installed dart 5.1 on my ubuntu which installed on parallel desktop. I tested by running the tutorial binaries in dart source files, and they work fine.
However, when I try to build my own code in another dir, let's say ~/proj/dart-test/ with main.cpp as follows.
I separate the compiling process from linking process with the following command.
compile
g++ -c main.cpp -Wall -msse2 -fPIC -std=c++11 -I/usr/include/eigen3 -I/usr/include/bullet --verboselink
g++ -o main main.o- -lboost_system -lBulletSoftBody -lBulletDynamics -lBulletCollision -lLinearMath -lassimp -ldart -Wl,--verboseAnd the compile process is fine, no error or warning. However, link process dump the following message, which shows that undefined reference to Skeleton::create (where the verbose options shows that I've link the libdart.so). What did I miss?
