[Help, please] Problems building source code on Windows

[phamhoanganhbk]

Hi,
I have solved the problem.
For those new (like me) on Windows who want to test the samples
Step 1: Download source code (not Installer)
Step 2: CMake GUI, follow the author's instructions. But pay attention to click on MRPT_BUILD_EXAMPLES (I forgot in this step).
Step 3: Link *.dll libraries to sample projects.

Hi,

If you git cloned the sources, why is cmake detecting what seems to be an already built version under C:/Program Files/mrpt-2.5.6/... ??

If you formerly installed mrpt in Windows with the installer, please uninstall it first (through the usual "Control Panel -> Apps" ), remove the cmake build directory, open cmake-gui again, select as source dir the place where you cloned the repo, and as build directory a new, empty directory somewhere else, and try again...

It's supposed to build ok, including nanogui, under Windows on our CI pipeline so it should work... let me know if you still have problems after following those steps.

Hi @jlblancoc
Thank you for your reply.
I uninstalled the mrpt installer and then i removed the cmake build directory of slam_icp_simple_example (because i just want to run the sample, i don't know if i need to build the mrpt project first?).
Then it came up with another error
