[GitHub] [incubator-nuttx] kernelgurumeditation opened a new issue #2323: Howto to build external apps(elf)?
kernelgurumeditation opened a new issue #2323:
URL: https://github.com/apache/incubator-nuttx/issues/2323
Hello...
I have read all the howtos, videos..., tried with symbols, without symbols.
Gone back to 9. ... 8... versions
and it never works....
I enabled elf loader debug in the Nuttx, and it seems that it fails to parse the elf file(the text, data section size is read as zero..)
It seems that I'm not creating the elf files correctly but followed the instructions in the official wiki...
Does this work? currently? if so can someone point me to how to do it?
I just want to build an elf hello world, put it on a filesystem, and run it... I have seen videos from Alan.. it worked at some time...
Any help will be very appreciated

@btashton, unfortunately, no, the other issue is an error linking.
This is about building a standalone elf file, with or without symbols, as described:
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629543
In this case, It builds, but when I try to run it on the board it fails.
I have enabled the elf loader debug and I'm seeing very strange things when it loads the elf section headers.... all the values seem to be wrong regarding endianness.... but the elf header is read correctly and the values are correct in the file...
Very strange

Alan also your tutorial required people to supply things that are already in the `scripts/Make.defs` file that is exported (maybe that file did not exist at the time?). We should probably show people how to make use of that rather than supply on the command line.
Personally I find that the improvements made for including external folders for apps / board / arch much easier to work with.

hi @kernelgurumeditation I tested it in the middle of 2018 at that time version was 7.25! I need to tested it to verify if someone break it in this mean time.

@kernelgurumeditation also is this the same issue you opened in the Apps repo that we commented on? If so we should probably close this and keep the conversation there.
