Tips and tricks

How to build from source

To install ViSP with homebrew after building from source you may run:

$ brew install visp --build-from-source

To know which are the additional build options, run:

$ brew options visp
--c++11
    Build using C++11 mode
--without-gsl
    Build without gsl support
--without-libdc1394
    Build without libdc1394 support
--without-libxml2
    Build without libxml2 support
--without-opencv3
    Build without opencv3 support
--without-x11
    Build without x11 support
--without-zbar
    Build without zbar support

For example to disable xml support, you may run

$ brew install visp --build-from-source --without-libxml2

/usr/local/include/visp is not writable

If during ViSP installation you get the following error

$ brew install visp
...
==> Pouring visp-3.0.0.el_capitan.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink include/visp/visp_modules.h
/usr/local/include/visp is not writable.
You can try again using:
  brew link visp
...

it means maybe that you install other softwares without brew in /usr/local. A work arround is to change the owner of the corresponding folder like:

$ sudo chown {your-user-name} /usr/local/include
