Adopt emb.LV to emb.Linux Target ARM9 Prozessor

[Michael.Phillips]

Hi,

Based on this output, it appears that critical sections code has not been defined. This might be due to missing defines in the makefile.

Hello,Michael

         I changed the third toolchain and made some changes in the CCodeGen,We can build arm-elf-rt.a and arm-elf-rtd.a,But when i build the program in the labview,the new error appeared :

D:\program files\labview 8.5\Targets\NI\Embedded\unix\m5329evb\libs\arm-elf-rt.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: ld returned 1 exit status

Can you give me some advice?Thank you very much!

Hi,

As far as I know, you only need ranlib with dynamic libraries, but you are building the runtime libraries as static libraries. Are you using the '-l' option in your script linker VI? If so, you should just include the path/name.a of the libraries.

Hello,Michael

      I added the path/name.a of the libraries in the LEP_unix_m5329evb_Prepare.vi,but the error is the same?Maybe it is about the makefile?

In the labview project:

My complier flags is as follows:

-g -w -I. -DCHeadless=0 -Dlinux -fno-strict-aliasing -fno-common -fomit-frame-pointer 

My linker flag is as follows

-g-m5307 -lc -lgcc -lm -lstdc++ 

The cflags in the makefile is as follows:

CFLAGS = -DCHeadless=1 $(OPTS) -Wall -Dlinux -D_LIB -fno-strict-aliasing -fno-common -S

Thank you

Hi,

Can you send the Makefiles? Also, set breakpoints in the VIs that script the compiler and the linker and send us the command line strings that are sent from LabVIEW.

Hello,Michael

       The Makefile i used is as follows,It's so strange that i have already added the 'ranlib' in the Makefile,but the error is the same!

Hello,Michael

        I build a simple library in the linux,the same error appeared.

[root@localhost test]# arm-elf-gcc -c fun.c
[root@localhost test]# arm-elf-ar q func.a fun.c
[root@localhost test]# arm-elf-gcc -I./main.c fun.a
fun.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: ld returned 1 exit status

But when i did the same work in the cygwin,there wasn't any error,At the same time it cann't build the a.exe.

Maybe it's the complier's problem,isn't it?

Thank you very much!

Hello,Michael

        Could send me the third toolchain (about the armtools) in the Phytec LPC229x,eCos target ,or where can i down it?I think maybe it's the problem about my armtools in the cygwin.Thank you very much!

Hi,

Instructions on installing the ecos toolchain are located here: http://ecos.sourceware.org/getstart.html. Good luck!

Hello,Michael

      It can build the .out file now  except the warning:

/armtools/arm-elf/bin/ld.real: warning: cannot find entry symbol _start; defaulting to 00008000

I want to ask you about how to set the symbol _start.Thank you!
