There must be some underlying path misconfiguration causing this issue, and ideally we would fix that rather than having to add these hacks every time we inherit nativesdk. 15497 1 liezhi.yang 2011-08-16 20:36:55 +0000 Hi Paul, Would you please add more info: 1) where is the nasty hacks 2) How to reproduce the "doesn't seem to be able to find by itself" thank you very much! 15504 2 bluelightning 2011-08-17 03:36:18 +0000 1) We have the following added to EXTRA_OECONF in meta/recipes-qt/qt4-tools-nativesdk.inc: -I${STAGING_DIR_HOST}${SDKPATHNATIVE}/usr/include/c++ \ -I${STAGING_DIR_HOST}${SDKPATHNATIVE}/usr/include/c++/${TARGET_SYS} \ -L${STAGING_DIR_HOST}${SDKPATHNATIVE}/lib \ -L${STAGING_DIR_HOST}${SDKPATHNATIVE}/usr/lib" Normally the compiler and linker should be able to find things in these standard paths by themselves, but for some reason with nativesdk.bbclass they can't. 2) Just remove the lines above and you'll find the build of qt4-tools-nativesdk will fail to find basic stuff like iostream. 15653 3 kai.kang 2011-08-23 02:18:52 +0000 post 1.1 16095 4 kai.kang 2011-09-07 19:17:33 +0000 I have send a commit to fix this bug, just because includedir_nativesdk is not set. commit 9ce2cc6e14270c94d97f1bb3ede8e9321a8192b8 16109 5 liang.li2 2011-09-08 18:25:19 +0000 now in meta/recipes-qt/qt4/qt4-tools-nativesdk.inc, no lines described in Comment 2, and run "bitbake qt4-tools-nativesdk", no error met,so verified it. git info :52835dd30110d51a839872f198eef3b12e369850 git branch : poky/master test env: host : ubuntu 10.10 x86_64 kernel :2.6.35-30-generic #56-Ubuntu SMP
