I built SDK for i686 + arm to easily run on 32bit Linux versions (i686). I installed Eclipse x86_64 and tryed to configure my i686 SDK at Yocto ADT plugin. No success. It says, SDK arch and host arch are different. I used my i686 SDK in my x86_64 Linux without problems for year. Why Eclipse ADT plugin complains? If I'll build x86_86 SDK I allowed to use it with my Eclipse x86_64. The wrong check (it says, I can't use i686 gcc to build with Eclipse x86_64!) forces me to change my SDK to x86_64 arch and stop supporintg i686. Or build two SDKs for i686 and x86_64. I think, line 149 of http://git.yoctoproject.org/cgit/cgit.cgi/eclipse-poky-contrib/tree/plugins/org.yocto.sdk.ide/src/org/yocto/sdk/ide/YoctoSDKChecker.java#n149 is completely incorrect. the check has to be about like this: if ( host_arch != "x86_64" && sdk_arch != host_arch) return( MISMATCH); or: if ( host_arch LIKE "i\d\d\d" && sdk_arch != host_arch) return( MISMATCH); or (more strict, using JavaScript syntax): ha = host_arch.replace( 'i', '').replace( '_', '').toInt() sa = sdk_arch.replace( 'i', '').replace( '_', '').toInt(); if ( sa > ha) return( MISMATCH); 77215 1 brian.avery 2017-09-28 23:27:39 +0000 Question: I commented out the sdk check as a quick test and found that for autotools at least, the configure fails if I use a 586 sdk on an x86-64 host . It fails due to gcc failing to find libgcc and fails to find crtbegin.o. If i source the 586 env from a shell I see the same failure if I try to build a hello.c. How were you building with the 586 sdk from the command line? 77378 2 dvorkin 2017-10-05 07:36:37 +0000 I'm building programs with my cross-gcc from i686 SDK without problems. I'm using i686 SDK, built from scratch with yocto on my Mageia distribution. No external libraries/gcc used, except SDL/libsdl-native. 77426 3 sjolley.yp.pm 2017-10-06 13:59:46 +0000 Brian, I believe the question was answered. 78610 4 brian.avery 2017-12-08 19:09:06 +0000 Given current resources, we won't be able to address this. Suggested workaround is to build both the 32 and 64 bit sdks.
