The following simple main.cpp, with a single include and no body, is enough to test: #include <bits/c++config.h> 66774 1 michel.dhooge 2016-09-30 19:50:02 +0000 To be sure, I compared with a plain genericx86-64 meta-toolchain (i.e. without DEFAULTTUNE set to x86-64-x32). The headers are also in a subfolder (x86_64-poky-linux), but they are correctly found by the g++ compiler. HTH 66901 2 juro.bystricky 2016-10-04 20:45:58 +0000 Yes, CPP is looking for the include files in a folder which does not exist. This can/should be fixed by a symlink in location: <sdkinstall>/sysroots/x86_64_x32-poky-linux-gnux32/usr/include/c++/6.2.0 which should contain a symlink named "x86_64-poky-linux" with the target "x86_64-poky-linux-gnux32" Because CPP looks for the include files in: <sdkinstall>/sysroots/x86_64_x32-poky-linux-gnux32/usr/include/c++/6.2.0/x86_64-poky-linux however the files are located in the folder <sdkinstall>/sysroots/x86_64_x32-poky-linux-gnux32/usr/include/c++/6.2.0/x86_64-poky-linux-gnunx32 67091 3 juro.bystricky 2016-10-10 16:24:26 +0000 Patch fixing the problem merged with master: https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=8209a01242b3ea265c69049879e9ade951bf9602
