[ptxdist] ptxdist commands

[Sophie CARAYOL]

Hi,

I don't find some explanations about ptxdist in the developer's manual.
- What's the difference between 'ptxdist clean' 'ptxdist drop'
- If I made some modifications on files (for example in u-boot or kernel),
what is the right command to re-build the project.

Best regards,

Sophie

"clean" removes files, while "drop" only remove state information.

PTXdist works with states for every single package. It walks through the main 
states in the following order:

 - get: get package sources
 - extract: extract package (its archive for example)
 - prepare: run configure stages for this package
 - compile: compile the sources of this package
 - install: install the results into the corresponding sysroot/
 - targetinstall: create the content for the ipkg and install files for target
                  into root/

So it depends on what you want PTXdist to do again. If you have modified 
sources in the build directory of a package and you want to force PTXdist to 
re-compile this changes again, just drop the package's "compile" stage. In the 
case of the kernel:

  ptxdist targetinstall kernel
  do {
      <running the kernel, it does not work, change some code in the kernel
       source tree>
      ptxdist drop kernel.compile
      ptxdist targetinstall kernel
  } while (!does_work_now)

Maybe the section "Using an External Kernel Source Tree" in the manual can help 
you.

Regards,
Jürgen
