MATLAB bindings: Matlab crash on semantic error

The iDynTreeMATLAB_wrap.cxx file gets compiled in the iDynTreeMATLAB_wrap.mexa64 file (the extension could change in different architectures/OSs ).
This file (and the Matlab classes contained in ) are then installed in ${CMAKE_INSTALL_PREFIX}/mex/. Consequently you should add to your path that directory.. but this is currently lacking from the README, because if you where using the codyco-superbuild you had already instructions on how to add that directory to Matlab path... thanks for spotting this lack!

I am not a great Matlab user, are this instructions 8aca613 enough or we need to clarify the necessary steps?

Thanks Silvio,

I have found the mex64 file in the following way:

 'kammo@kammo-Latitude-E5540:~$ sudo find / -name 'iDynTreeMATLAB_wrap.mexa64'
[sudo] password for kammo: 
/home/kammo/Repos/codyco-superbuild/libraries/iDynTree/build/lib/x86_64-linux-gnu/iDynTreeMATLAB_wrap.mexa64

The directory in which it has been placed seems different from the ones you suggested in 8aca613

Test 1 works correctly

Test 2 makes matlab crash. The crash dump is reported below

Mh... that is the one compiled in the build directory... did you run the install command on iDynTree repo, directly from the repo or by doing a make on codyco-superbuild ?

from idyntree.

DiegoRomeres commented on August 17, 2024

I got the same results as Raffaello, Test1 works and Test2 crushes Matlab.

I run the install command directly on the repo.

from idyntree.

raffaello-camoriano commented on August 17, 2024

I have tried both ways.

I went to codyco-superbuild/libraries/iDynTree/build, issued a ccmake .. and set the option IDYNTREE_USES_MATLAB = ON. Then I issued a make instruction.
I did not issue a sudo make install (since the instructions do not say it)
There is no {CMAKE_INSTALL_PREFIX}/mex directory
I assumed that SUPERBUILD_BUILD_DIRECTORY means CMAKE_INSTALL_PREFIX
I set CODYCO_USES_MATLAB = ON
and left CMAKE_INSTALL_PREFIX = /usr/local
I issued a make update-all in codyco-superbuild/build
I did not issue a sudo make install cmd (since the instructions do not say it)
There is no SUPERBUILD_BUILD_DIRECTORY/install/mex directory

from idyntree.

DiegoRomeres commented on August 17, 2024

I tryed both cases as well and the results doesn't change.

Running the code line by line I saw that the error occurs in the last line:
O_A_wrong = transform_B_A*O_B;

I guess the problem is related to the method 'Inverse()' of 'iDynTree.Transform' since the previous code worked properly. The error that apperas in the Matlab command Window befor the crash is:

[ERROR] TransformSemantics :: apply : Mismatch between orientationFrame of first operand and coordinateFrame of second operand

from idyntree.

traversaro commented on August 17, 2024

Sorry guys, this is my fault. : )

Basically the error handling procedure is calling an assert(false) if you do something wrong, to exit the program.. but this is not desirable in bindings where if you exit the program you exit the all interpreter!
This happens for example in :

The easiest fix is to remove those assert(false), or compile the library in Release.

Notice that this was mentioned in the tutorial: Semantics check will prevent us from doing stupid things (this will result in an error)

from idyntree.

DiegoRomeres commented on August 17, 2024

I tried to run the test example after commenting the assert(false) you indicated us, but the problem is not solved.
At a first view I didn't find the correct one to remove, but I will check the file more accurately and I will be back to you later.

from idyntree.

@nunoguedelha is working on an improved version of the semantics checking, we will push it soon and it will solve the problem of Matlab crashing on semantic error.

traversaro commented on August 17, 2024

Semantics was removed in #704, so automatically this bug is fixed.
