Created attachment 3949 [details] console.log of failed nativesdk-gnutls build I have a system with a core-image-sato eSDK (poky-glibc-x86_64-core-image-sato-core2-64-toolchain-2.3.sh) installed in the default location (/opt/poky). When trying to build nativesdk-gnutls on that system *without* having sourced the environment setup scripts the nativesdk-gnutls build fails because a header from the installed toolchain is used rather than the header from the sysroot and a struct ends up being redefined. Include paths for the gnutls-nativesdk build include the installed location of nativesdk. I've not yet determined whether this is a gnutls issue or whether it's a general nativesdk issue. Attached is the console.log but the interesting parts, I believe, are: x86_64-pokysdk-linux-libtool: compile: x86_64-pokysdk-linux-gcc

This appears to be specific to nativesdk-gnutls, or at least I haven't managed to make other nativesdk- recipes fail the same way. In the generated Makefile I see: CPPFLAGS = -I/opt/poky/2.3/sysroots/x86_64-pokysdk-linux/usr/include
I could reproduce (similar/equivalent problem) quite easily: 1. Install eSDK (into default place /opt/poky..). 2. Build nativsdk-gnutls In my case the build was successful, but the log.do_compile did also contain -I/opt/poky/2.3+snapshot/sysroots/x86_64-pokysdk-linux/usr/include references. As there were no discrepancies between various include files (taken from /opt/poky/2.3+snapshot/sysroots/x86_64-pokysdk-linux/usr/include), the build did not fail. So this problem may have been around unnoticed for a while. 3. Removing/renaming the eSDK fixed the problem: no references of -I/opt/poky/2.3+snapshot/sysroots/x86_64-pokysdk-linux/usr/include were present anymore. So it is just the *presence* of the eSDK in the *default* location that causes this particular bug.
This is not nativesdk-gnutls specific, "configure" is called with "--includedir=/opt/poky/2.4/sysroot/<build-host>/usr/include" for all nativesdk apps. However only nativesdk-gnutls seems actually use the value, trying to be smart and . The culprit seems to be in lib-link.m4, initializing $additional_includeddir for CPPFLAGS. The comment says: Potentially add $additional_includeddir to $CPPFLAGS. But don't add it 1. if it's the standard /usr/include 2. if it's already present in $CPPFLAGS 3. if it's /usr/local/include and we are using GCC on Linux 4. if it doesn't exist as a directory. We get added due to 4., if the directory /opt/poky/... exists. That also explains why gnutls-native works fine (--includedir=/usr/include). So I think the best way to address this is not to add it also in additional case: 5. if it's in /opt/poky I'll test this theory.
The problem was caused by mismatched include files. They were mismatched because the "master" git repo did not contain the "snapshot" version, so nativesdk-gnutls build looked into incorrect /opt/poky/xxx folder. (should have been /opt/poky/xxx+snapshot). This problem was fixed/should not be observed after: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=51cc0b07a14277c71a3b6184575fe30ab489c717
