[Atcollab-general] compiling labca into matlab
|

Hi, all,
We are trying to use the matlab compiler to compile m-files that contain lcaGet and lcaPut calls to create executable files on windows.
Does anyone know the correct >>mcc command?
Thanks, Jeff

I just checked the symbols in the compiled files using nm and they do not contain the global symbols for passFunction or trackFunction, only local. Matlab has changed the way it MEXs again.
Matlab2016a
[opi@CR01OPI05 ~]$ cd /usr/local/MATLAB/R2016a/extern/lib/glnxa64/
fexport.map mexFunction.map
Matlab2017a
user@asci: /usr/local/MATLAB/R2017a ls extern/lib/glnxa64/
c_exportsmexfileversion.map fexport.map fortran_exportsmexfileversion.map mexFunction.map
It now has a two layer approach with LINKEXPORT(mexFunction.map) followed by LINKEXPORTVER (c_exportsmexfileversion.map). So what works for me is to make some small changes to the *.map file and mexpassmethod.m (attached). The change appears to have happened in R2016b!
Some nitty gritty detail below if you're interested.
Can people also check that these changes don't break anything before I commit this change to AT2.0?
I don't know how to push this out to AT1.4, so if it works can someone please do this?
Eugene

Hi there,
We just noticed yesterday some similar problems with a similar configuration "CentOS7 + Matlab2017a + AT1.3". AT1.4 also fails, but AT1.3 has the wonderful ability to crash Matlab2017a every time it is executed. It has been recently updated, the previous version was "CentOS7 + Matlab2015a + AT1.3", so far we workaround using the old release. In our case, the same files are used by different machines with different Matlab versions so we decided not to recompile yet.
Eugene, do you by any chance know if the recompiled files work in earlier versions?
Best regards,
Zeus

Error using atpass
Element # 0: Library file: /usr/home/at14/atintegrators/AperturePass.mexa64, No passFunction or trackFunction available
I've recompiles all the pass methods using "atmexall" and compiles successfully.
Has anyone had this problem before? Windows + Matlab2016a + AT2.0 is OK.
