Compiling the IPCV for Scilab 2024 (Mac Intel 64 bit)

Question

I have a 64 bit Mac on Intel. I am trying to install the IPCV (Image Processing and Computer Vision) toolbox for Scilab 2024.

I have the XCode installed and I have run the xcode-select command for agreeing to the license and all other instructions which are available on the Internet.

When I initiate the installation I have the following set of error messages after all the initial verbose text:

Building gateway...

atomsInstall: Error while building the toolbox '/Applications/scilab-2024.0.0.app/Contents/share/scilab/contrib/IPCV/4.1.2'

I am wondering that inspite of the GCC being installed on homebrew and the XCode being installed, the C compilation is not happening.

Answer 1

I suggest that in the file sci_gateway/cpp/builder_gateway_cpp.sce you change the line

inter_cflags = ' -std=c++11 -stdlib=libc++ -I'+OPENCV_INCLUDE;

by

inter_cflags = OPENCV_INCLUDE;

New official builds of IPCV for Intel and arm64 will be available this week.
