[yocto] recipe md5sum and sha256sum changing

[Edward Vidal]

Hello All,
I used the following to create a recipe.

 recipetool create  -o 
/home/vidal/wkg/yocto/myhdl_recipe/poky/meta/recipes-devtools/python/python-myhdl_1.0.0.bb
  https://github.com/jandecaluwe/myhdl.git

This provided the following:
LICENSE = CLOSED
LIC_FILES_CHKSUM = 

SRC_URI = https://github.com/jandecaluwe/myhdl.git;
SRC_URI[md5sum] = 6f56a9bcbd03a9c8036f87f32f9adc47
SRC_URI[sha256sum] = 
7766c49947c6574c8fb35d0dfcd795ada1e4e457ab5b15499d7000909b8e46e9

When I run bitbake python-mydhl
the md5sum and sha256sum change everytime I run the command.

If this change is expected (e.g. you have upgraded to a new version without 
updating the checksums) then you can use these lines within the recipe:
SRC_URI[md5sum] = a4b1db68cde5b996661caa6abce2cb45
SRC_URI[sha256sum] = 
dc35dc44e0a480097eb1c4dd3df739396e96c8d7648bd9b9d347d02d34bbcd01
Otherwise you should retry the download and/or check with upstream to determine 
if the file has become corrupted or otherwise unexpectedly modified.

recipetool obviously doesn't detect that your HTTP URL is actually a git
clone.  Change the URL to something like git://github.com/jandecaluwe/...
so it knows to use a git fetcher and not wget.  This also means you don't
need to set the checksums.
