If ./configure bails out on cross-compiling, then it is broken -- period. Autotools has been written to support multiple platforms, if it does not, we need to fix it. OpenEmbedded has already achieved a lot in teaching upstream authors about hardcoded assumptions, abusing autotools, etc. OE will continue its fight to improve the build quality. > It has to be slower though, how > much I dunno.

Sounds like you really should have checked upstream documentation.

Uhm, so your argument boils down to just because more people are using it... I don't find that a particular convincing one. So if it was you to decide, you would ditch OE and use Ubuntu Mobile or RedHat or Debian on the phone? > The other things that bother me about OE are the lack of SRPM type > source capture -- critical feature for license compliance -- and the > epileptic-fit inducing problems with -devel type include / libs > packaging, being able to pass around and host-install cross-devel > packages to cross compile other packages against easily. If I use RPM > or .deb I get grown-up support for this. Dunno about grown-up support, but OE can distribute sources and patches fine. :M:
