Cross-compiling issues with toolchain DS1401

Hi :wave:

I am using Acados on windows with MATLAB R2020b and going to cross compile Acados to library, which will be used for the build of my Simulink model on DS1401 by ConfigurationDesk. I adapted the Toolchain-dSpaceDS1401.cmake according to the path on my PC and it didn’t work with the error:

Linking C static library cmTC_152f6.lib
CMAKE_AR-NOTFOUND qc cmTC_152f6.lib CMakeFiles/cmTC_152f6.dir/isa_test.c.obj
Error running link command: Das System kann die angegebene Datei nicht finden

, which I think means that it cannot find the ar.exe for cmake. Then I add the path manually in the Toolchain-dSpaceDS1401.cmake as below:

SET(CMAKE_AR      "C:/Program Files/dSPACE RCPHIL 2020-B/Compiler/Linux440_550/target/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-ar.exe" CACHE FILEPATH "Archiver")

Then the cross compiling worked. However, the libraries generated are all .lib files, which I thought should be .a libraries for embedded system. When I replace the headers and libraries with the results of cross-compiling, set the custom code and built my Simulink model by ConfigurationDesk, I got the error saying

c:/program files/dspace rcphil 2020-b/compiler/linux440_550/target/arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/5.5.0/../../../../arm-linux-gnueabihf/bin/ld.exe: \acados\lib\acados.lib(ocp_nlp_common.c.obj): Relocations in generic ELF (EM: 20)
acados.lib: error adding symbols: File in wrong format

I don’t know which step is wrong in my cross-compiling process, which led to the generation of libs with wrong format. I would appreciate it if someone can give me a hint on how to handle this error.

This is the cmake file I am using now:

Thanks in advance!
