cannot generate code in matlab2023b

[muler415]

when I opened model_sample.slx, used embeded coder in simulink which used ert_linux.tlc, after clicking generate code, there is error as following. please let me know anything I missed.

Thanks/Forrest

The ert_linux is intended for GNU/Linux targets, native and cross compiled and can be used even as experimental base for some other POSIX compliant RTOSes, tested with NuttX. You can see that the message specifies that "Clang v3.1" or "gmake (64-bit Mac), GNU gcc/g++" or "gmake (64-bit Linux)" toolchain is missing. You seems to have some Linux targets registered but they are some CMake specific ones.

The primary information which you should report is what you want achieve. i.e. build my model for Raspberry Pi 3 RT Linux target on Windows host. Or I want to build for x86 64-bit Ubuntu PC target with COMEDI cards inserted.

Even in this case, I have probably bad news for you, I have newer tested Matlab on some Windows based host from end of nineties and ert_linux has not been tested and tuned (and hacked, Windows are non-standard, non-POSIX environment) for such use. ert_linux has been successfully used on x86_64 Debian system running Preemp RT kernels, graphics etc to generate models run on same computer with up to 30 kHz applications, it has been used to build and croscompile models for Raspberry Pi, AMD/Xilinx Zynq systems, 64-bit Raspberry Pi targets, Nvidia Jetson and many more targets. But for all these tasks we have used GNU/Linux based host systems for development.

Clean fixes to run it even on Windows are welcomed but dirty hacks not.

Thanks for supporting. do you have detail how to install these toolchains("Clang v3.1" or "gmake (64-bit Mac), GNU gcc/g++" or "gmake (64-bit Linux)") on windows? how to register these toolchains on matlab? I cannot find it in readme. please help.

Thanks/Forrest

I cannot help without extraordinary time spent and installing Windows somewhere etc...
There is not necessary readme to install standard toolchain on any of GNU/Linux distribution. It is there when you have environment to compile arbitrarily C program. You get superset of these tools by installing package build-essential on Debian, Ubuntu, you use zypper info -t pattern devel_basis on Suse, basically when Matlab supports and is setup for Simulink acceleration and S-functions builds you have all required tools. For cross compile for ARM AArch64 you add crossbuild-essential-arm64 and ert_linux works. On windows, there is problem to install even GNU/make, system is incapable to provide basic services so you need to install whole environment like https://en.wikipedia.org/wiki/MinGW, https://en.wikipedia.org/wiki/Cygwin but the the paths in that environment do not match paths in native Wndows programs so you need to use paths mapping etc. It is horror and I have no time to even glimpse at it till summer. And I expect that there would be more problems in ert_linux generated Makefiles caused by this MS Windows system mess. If you want to try ert_linux now setup some Linux system and start Matlab on it. Even Microsoft cannot run they latest AI tools without GNU/Linux installed in WSL as I have read in the news and we have much less resources and motivation to spent weeks on their broken system.

[ppisa]

And you do not specify your target, motivation, project so I cannot have idea and response if the idea is feasible to be solved by ert_linux, it is minimalist and works well, in the fact in all tested version much better from real-time timing guarantees rules than Matworks original code, but they seem to not care for fundamental breaking basic RT Linux application design rules when we reported them to developers around their coders tools. But many Simulink tools do not work with our version on the other hand because they rely on some wrappers etc. which we have not resorces to implement yet.

Thanks for explaination. I understood. I tried to make it work on my win11 Matlab, targeting machine is Ubuntu 22.04 with patch Linux Preempt-RT. I have installed mingw64 and cross-compiler aarch64-linux-gnu on my win11. here is what I tried:
comments these toolchains line in ert_linux.tmf by workaround this issue. and now it can generate code.
##Opt in to simplified format by specifying compatible Toolchain
##TOOLCHAIN_NAME = ["Clang v3.1 | gmake (64-bit Mac)",
##"GNU gcc/g++ | gmake (64-bit Linux)"]

however when I tried to compile model_sample.slx in embeded coder by make command - 'make_rtw OPT_OPTS="-O2 -ggdb -Wall" CC=aarch64-linux-gnu-gcc CPP=aarch64-linux-gnu-gcc'. it will throw failure. anything should I change ert_linux.tmf to fix this failure.

[muler415]

I spent some time to check tmf file and found it host on Unix platform. but in my case I used Windows as matlab host. I changed HOST=PC in ert_linux.tmf. the issue is gone. It can compile generated code now.

Hello @xjhouska @ppisa
Is using MATLAB on a Linux machine to generate Linux-compatible code mandatory?
