Could NOT find GLUT (missing: GLUT_glut_LIBRARY GLUT_INCLUDE_DIR) about splishsplash

[janbender]

Is GLUT installed on your system?

[watersky803]

After I installed the GLUT, it can be configured and generated, but when I used Make to compile the makefile. there are a lot of errors as follows. could you help me figure out where I need to pay attention? how to deal with those errors? thank you. My system is ubuntu 16.04 64 bits. CMAKE 3.16.4 64 bits.

@watersky803 did you figure out how to fix the issue to do with

PositionBasedDynamics/CMakeFiles/PositionBasedDynamics.dir/build.make:105: recipe for target 'PositionBasedDynamics/CMakeFiles/PositionBasedDynamics.dir/PositionBasedElasticRods.cpp.o' failed

I'm getting this error too. I do have GLUT here /usr/lib/x86_64-linux-gnu/libglut.so

[ankurhanda]

OK -- so this is the fix

SPlisHSPlasH/build/extern/PositionBasedDynamics/src/Ext_PBD/PositionBasedDynamics/PositionBasedElasticRods.cpp:778:45: note:   mismatched types ‘std::initializer_list<_Tp>’ and ‘float’
    maxError = std::max(maxError, abs(rhs[i]));

In this file the abs(rhs[i]) should be replaced with (float)abs(rhs[i])

[janbender]

Can you tell me on which system you are compiling the code and which settings did you use in CMake?

[ankurhanda]

Linux 4.15.0-88-generic #88~16.04.1-Ubuntu SMP Wed Feb 12 04:19:15 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I didn't change CMake at all.

Thank you.

[watersky803]

OK -- so this is the fix

SPlisHSPlasH/build/extern/PositionBasedDynamics/src/Ext_PBD/PositionBasedDynamics/PositionBasedElasticRods.cpp:778:45: note:   mismatched types ‘std::initializer_list<_Tp>’ and ‘float’
    maxError = std::max(maxError, abs(rhs[i]));

In this file the abs(rhs[i]) should be replaced with (float)abs(rhs[i])

Thanks

[janbender]

I just checked the code. rhs[i] is already a float. So I wonder why abs does not return a float. Can you try to use the following code on your system:

maxError = std::max(maxError, fabs(rhs[i]));

[codylico]

Maybe that call to abs(rhs[i]) should be a call to std::abs(rhs[i])? The first one may be referencing the C library version that only takes int.

[janbender]

I fixed that. Could you please try again with the udated version?

[codylico]

I tested the updated version. It successfully compiles on Ubuntu 18 using CMake.
