Compile error on FMU

[mpcagro]

I get the following compile error, when I try to compile export FMU code from 20-sim:

>make
------------------------------------------------------------
20-sim standalone co-simulation FMU export for:
vehicle
------------------------------------------------------------
[cc] src/fmi2Functions.c
[cc] src/EulerAngles.c
[cc] src/motionprofiles.c
[cc] src/xxfuncs.c
[cc] src/xxinteg.c
[cc] src/xxinverse.c
[cc] src/xxmatrix.c
[cc] src/xxmodel.c
[cc] src/xxsubmod.c
make: *** No rule to make target `project/gcc/Table2D.o', needed by `dll'.  Stop.

The bug is apperring with gcc and make on ubuntu 14.04. But is is clearly a mistake in the make file that is being exported.

I am still able to use the old version in 4.6.1, that comes with the tool.

Ready!

The main problem right now is that I am unable to use the new variable step size solver export.

Hi Martin, My guess is that the fix for this is the following Makefile change: https://github.com/controllab/fmi-export-20sim/commit/2567e806f8e71d528cc86306b005c343ef49c2ee

This fix will be included in the upcoming 20-sim 4.6.2 release (and is already included in 4.6.2-intocps)

Which version of 20-sim are you using? If you are using the code generation template from Github, it should already be fixed...

Hi Marcel

I am currently mainly using 4.6.1 and testing 4.6.2-intocps. I thend to not move forward until I have tested that everything from the old version works in the new one. I tried to download a new fmu export from this page (mine could have been to old like you indicated). What happende, was the following:

Should I just ignore this error and is there a way to stop it from compiling automatically ?

[margro]

Hmm, that error is not good. Looks like an error in the template. Ignoring won't help you since any other compiler and the FMU builder will give a similar error.

Unfortunately, there is no easy way to stop it from compiling. The export searches for a suitable compiler and only skips compilation when VS2010, VS2013 and VS2015 are all three not found.

[margro]

On the other hand, it might be only VS2010 that is complaining about this... My guess is that it is fixed with: c0d159c11153809192816ce4568b23900907760b

[mpcagro]

Ok on the compile stuff. I was just wondering if it was possibly add a export flag for this in 20-sim. I will test again and see what happens !

[mpcagro]

Getting closer :-)
