By the way, is it still happening? |

This seems something that we solved in robotology-dependencies/qpOASES#7 and was solved upstream in https://projects.coin-or.org/qpOASES/changeset/255/, so probably a "strange" version of qpOASES is installed as per @S-Dafarra intuition. |

I've installed qpOases from source here https://github.com/robotology-dependencies/qpOASES |

That is strange. Can you return the output of: and: |

I guess this problem did not occur before? (Note: the error is expected if you compile qpOASES as a static library). |

A solution that I found is to build qpOASES with but it still doesn't work after rebuilding and installing qpOASES and idyntree. I have installed ipopt using |

To debug the issue even more, can you provide the full output of nm /usr/local/lib/libqpOASES.a? That should tell us which compilation unit (i.e. source file) actually inserted the problematic dgemm_ symbol. Are you sure that you do not have any other qpOASES installed in the system? In that case, is possible that the wrong include of qpOASES is used, resulting in that symbol being generated. You can check this with sudo updatedb && locate qpOASES.hpp.

Here's the folder, I've omitted the .git folder because it was too heavy for the upload on git. But if you need it I can divide it and upload it. here /usr/local/include/qpOASES/LapackBlasReplacement.hpp instead: |

Thanks!
Are you sure? From the content of the directory it seems that you cloned it from https://github.com/coin-or/qpOASES . You can easily check by running |
