Hi Guillaume,

Guillaume Le Vaill= ant <glv@posteo=2Enet> skribis:

I'm trying to get icedtea-6 to build on the core-updates= -frozen branch=2E
I fixed a few C/C++ related issues,
Thanks for fixing those! After <https://issues=2Eguix=2Egnu=2Eorg/49990#10>
Jul= ien mentioned on IRC that using an older GCC allowed us to work
around t= hose C++ issues, but your approach looks nicer to me=2E

but then I get this error:

Pr= eload failed: checksum of class list was incorrect=2E
make: *** [Makefi= le:2746: stamps/add-archive-ecj=2Estamp] Error 1

Woow, = never seen that=2E Julien, Ricardo, does that ring a bell?

Java is = the main stumbling block on core-updates-frozen; making
progress!
Thanks,
Ludo=E2=80=99=2E
