what’s the host PC environment?
Mine is Ubuntu 18.04. And I think 20.04 should also be good.
That looks like host PC environment issue, not SPE compiling issue.
Cross toolchain should be able to run first.
Correct result should look like:
building-pc:~/Work/jetson_sdk/32.5/spe-fw$ ldd /home/chenjian/Tools/gcc-arm-none-eabi-4_8-2014q3/bin/arm-none-eabi-gcc

libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7c12000)
/lib/ld-linux.so.2 (0xf7f2a000)

I fixed the issue by reading this post:
Now its compiling. :) Thanks for your efforts.
Hi Chen Jian,
What is this below docs error?? Do I really need to build docs or should I remove from makefile?
mkdir -p /home/ayyappan/nvidia/SPE/l4t-rt/rt-aux-cpu-demo/out/docs
DOXYGEN /home/ayyappan/nvidia/SPE/l4t-rt/rt-aux-cpu-demo/doc/doxyfile
make: *** [Makefile:375: /home/ayyappan/nvidia/SPE/l4t-rt/rt-aux-cpu-demo/out/docs/.stamp] Error 127

You can skip doc building and refer to online SPE doc.
Or you can check why doxygen fails.
Correct result should be:
building-pc:~/Work/jetson_sdk/32.5/spe-fw$ doxygen
error: Doxyfile not found and no input file specified!
Doxygen version 1.8.13
Copyright Dimitri van Heesch 1997-2015
You can use doxygen in a number of ways:
-
Use doxygen to generate a template configuration file:
doxygen [-s] -g [configName]If - is used for configName doxygen will write to standard output.
-
Use doxygen to update an old configuration file:
doxygen [-s] -u [configName] -
Use doxygen to generate documentation using an existing configuration file:
doxygen [configName]If - is used for configName doxygen will read from standard input.
-
Use doxygen to generate a template file controlling the layout of the
generated documentation:
doxygen -l [layoutFileName.xml] -
Use doxygen to generate a template style sheet file for RTF, HTML or Latex.
RTF: doxygen -w rtf styleSheetFile
HTML: doxygen -w html headerFile footerFile styleSheetFile [configFile]
LaTeX: doxygen -w latex headerFile footerFile styleSheetFile [configFile] -
Use doxygen to generate a rtf extensions file
RTF: doxygen -e rtf extensionsFile
If -s is specified the comments of the configuration items in the config file will be omitted.
If configName is omitted `Doxyfile’ will be used as a default.
-v print version string

Mine is Ubuntu 22.04.
We can close this thread. Its compiling now.
BTW, Ubunut 22.04 is good for compiling 32.7.3 BSP?
Though this is solved, I am curious, was this always running in a VM? That would explain a lot when files are present with correct permissions, but they cannot be found…it implies two different environments.
Btw, in theory, if you have the right release of cross tools and libraries to link against (no libraries needed if it is bare metal), then it should work with an Ubuntu 22.04 host PC. However, there is a lot going on, and I would recommend 18.04 if you run into any issues. The cross tools are known to work on 18.04 for the 32.7.3 BSP, but it would be a matter of testing and luck if they can be installed in 22.04 and work as expected.
see this Facing the below errors while building the kernel for Javier NX module - #21 by ayyappan.rathinam thread.
One of nvidia employee mentioned that it wont work as expected in ubuntu 22.04. I believe all nvidia guys are using ubuntu 18.04
YEs. I am using VM always. and nvidia is recommending dual os. I mean ubuntu 18.04
Hi chen Jian,
DOXYGEN errors resolved after install the latest version
gcc error resolved by following the below link
now SPE firmware is compiled without any errors. Plz close this topic
Thanks
