MeshViewer about pmp-library

[dsieger]

Hi,

There was indeed a bug in the cmake install script. I fixed this in this commit.

As for the linker errors: Can you make sure to link against the pmp_vis library in your cmake files? This should fix it.

Hope this helps,
Daniel

Hi Danel,
Thank you very much for your help, I try to add the pmp_vis library like this

cmake_minimum_required(VERSION 3.14)
project(MeshViewer)
set(CMAKE_CXX_STANDARD 14)
include_directories(/usr/local/include)
link_libraries(/usr/local/lib/libpmp_vis.a)
add_executable(MeshViewer main.cpp)
target_link_libraries(MeshViewer /usr/local/lib/libpmp.dylib)

but the error is:

does it mean that I should also add the openGL library in my cmakeList?

Well I add the Opengl into my project but there are still some errors:

Undefined symbols for architecture x86_64:

I have fixed all link errors but...another error occured

Hi,

This looks like you linked against a different imgui version. The version we include is 1.70, and the assertion you are getting reports "1.72 WIP".

Hi,

I had another look, and it indeed seems that installing through make install is broken in its current form.

In the meantime, I'd suggest to simply use the project template we are providing in the pmp-template repository. See also the quickstart guide.

Hope this helps,
Daniel

Thank you for your help! I've tried your advice and it worked very well.
