Adopt emb.LV to emb.Linux Target ARM9 Prozessor

[莲子]

hello,Mr Michael

   The error aboved is solved,but the new linking error appeared as follows:

Linking error:
lvEmbeddedMain.o:lvEmbeddedMain.c:(.text+0x49): undefined reference to `_LV_unix_init'
lvEmbeddedMain.o:lvEmbeddedMain.c:(.text+0x4e): undefined reference to `_LVCGenRTInit'
lvEmbeddedMain.o:lvEmbeddedMain.c:(.text+0x83): undefined reference to `_LVCGenRTRunTopLevelVI'

test.o:test.c:(.text+0xc4): undefined reference to `_RunVI'
collect2: ld returned 1 exit status

I don't know how to define the function in the target.

thank you!

Hi,

These functions are defined in C files in the runtime libraries, here <CCodeGen\libsrc\os\unix\LVUnixInit.c> and here <CCodeGen\libsrc\os\unix\ lvcgenrtinit.c>. These files need to be included when you build the runtime libraries and must be linked in.

Hello,Michael

      I found these functions in the CCodeGen,but I don't know  how to build the runtime libraries ?

IN the chapter 7-Porting the LabVIEW Embedded Run-Time and Analysis Libraries Source Code,I don't find the methods to build the library.Can you give an example ?

Thank you!

Hi,

How you build the run-time libraries depends on your tool chain. In most cases, a makefile is the method of choice. An example of this is located in labview\Targets\NI\Embedded\unix\build\.

hello.Michael

 The errors above  are sloved,but there is still a new question as follows:

/usr/local/lib/gcc/arm-elf/3.4.0-macraigor1/../../../../arm-elf/bin/ld: cannot find -lc
collect2: ld returned 1 exit status

I installed  gnutools-arm-elf-2.05.exe ,and I change it for the gnutools-arm-elf-2.04.exe,but the error is the same.

Maybe it is the problem about third toolchain.

Can you give me some advice?

Thank you!

Hi,

Can you give me the exact command string sent to the linker?

Hello,Michael

The linker is "-g -m5307 -lc -lpthread -lgcc -lm -lstdc++"

[Michael.Phillips]

Hi,

It appears that there is something wrong with the installation of the gcc toolchain you are using. Are you able to compile and link a simple C program? What version of the toolchain are you using, and where did you get it?

Hello,Michael

        The  gcc toolchain i used is gnutools-arm-elf-2.05.exe,where i down form  here:http://www.ocdemon.com/gnutools-arm-elf-2.05.exe.Is it right?

Hello,Michael

         Is the gcc toolchain  i chosed right?And there is another question occured to me,that is i can't build the makefile successfully,The makefile is in the attached files.

Thank you for giving me your advice.Thank you very much!
