Hello,

I have problems during compilation of the c code generated by RTW/Windows environment in Linux. I had error of missing header files, so copied all of the required headers from the matlab/rtw & matlab/simulink/ & matlab/extern/ directory but after that i have new issues like this one

/usr/lib/gcc/i686-linux-gnu/4.4.5/../../../../lib/crt1.o: In function `_start': (.text+0x18): undefined reference to `main' /tmp/cc6Qgk1k.o: In function `Test_initialize': Test.c:(.text+0x25a): undefined reference to `rt_InitInfAndNaN' collect2: ld returned 1 exit status

The command used to compile is " gcc -DRT filename.c"

Don't know why is it shouting in this function since we never modified anything in the code given by the RTW.

The whole program with other files could also be sent if required.

Any help would be welcomed.. as we have the same problem in all the codes from RTW.

Thanks and Best Regards,

Kareem.

Looks like you are still missing some files. Please try using the packNGo utility so that all required files are automatically packaged for relocation.

Oops, I just noticed that the compile command you are using is "gcc -DRT filename.c" - this is not sufficient. You clearly need to link against the other .c files in the folder. Your command should include the list of all the C files generated into that folder. In some cases, there may also be other library files to link against. I would recommend using the Makefile generated by Simulink to ensure that the right compiler/linker flags are present.

Hello,

if we use rsim.tlc target, does this work?

Thanks
