how to build Hugin?

[O.Bouizi]

Hello,

I am trying to build hugin from mercurial, following the instructions on the Panotools Wiki: https://wiki.panotools.org/Hugin_Compiling_Ubuntu

As the page was last edited in April 2017, I expected to have some issues. But I encountered many issues with the dependencies: exiv2 (v0.27.2, issue with auto_ptr that is deprecated), vigra (C++17 error about "throw", needs to use boost), enblend...

So, my question is: is there a more recent description of the compilation steps?

Thanks,

Othman.

The current version is in the file INSTALL_cmake in the repository. This is a very general instruction and covers only building Hugin.

The building of all dependencies is not covered - it is assumed that the libs from the corresponding repository are used.

PS: The mentioned errors in the dependencies seems to be caused by the compiling with C++17. Hugin needs only C++11. When compiling dependencies with C++17 probably newer versions of the libs are required - but that's completely untested.

Hi,

Thanks for your quick answer, as usual.

Indeed, building Hugin on Ubuntu is straightforward (contrary to CENTOS), but I had to dig a bit to find how to enable Lapack.

Would you mind adding -DENABLE_LAPACK:BOOL=ON in INSTALL_cmake? In the section "Important variables"? It might be helpful.

I'm not sure if using LAPACK brings some advantages. The options was added to silence a compiler warning in an (bundled) external library. But I'm not aware of some test, if using LAPACK brings a speed or stability improvement for the photometric optimizer (the only place where this lib is used in Hugin).

So in current state I hesitate this switch to the important chapter. If somebody does some tests which shows some advantages of this option in contrast to the default setting without LAPACK, I will add this setting to the INSTALL_cmake file.
