Hello,<br /><br />I am new to the Yocto project and need some help in solving a linker issue when compiling/linking an application using the SDK. It seems, that the compilation is completed, but the linker could not resolve to "_rtld_global_ro". Here is the output of the last stage<br />&lt;snip&gt;<br />...<br />
<div>/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: /opt/mydistro/1.0.0/sysroots/cortexa9t2hf-neon-poky-linux-gnueabi/usr/lib/libc.a(getcontext.o): in function `getcontext':</div>
<div>/usr/src/debug/glibc/2.29-r0/git/stdlib/../sysdeps/unix/sysv/linux/arm/getcontext.S:101: undefined reference to `_rtld_global_ro'</div>
<div>/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: /opt/mydistro/1.0.0/sysroots/cortexa9t2hf-neon-poky-linux-gnueabi/usr/lib/libc.a(setcontext.o): in function `__startcontext':</div>
<div>/usr/src/debug/glibc/2.29-r0/git/stdlib/../sysdeps/unix/sysv/linux/arm/setcontext.S:100: undefined reference to `_rtld_global_ro'</div>
<div>collect2: error: ld returned 1 exit status</div>
<div>makefile:116: recipe for target 'ortable' failed</div>
<div>make: *** [ortable] Error 1</div>
<div>&lt;/snip&gt;</div>
<br />What I can see from the output is, that both getcontext.S and setcontext.S are referencing to "_rtld_global_ro". What I do not understand is, why the glibc is located in the debug folder? Is this probably the issue?<br /><br />I have sourced the SDK using following command:<br />source /opt/mydistro/1.0.0/environment-setup-cortexa9t2hf-neon-poky-linux-gnueabi<br /><br />Here's image bb file (which I have used for building the SDK using this command (bitbake my-image -c populate_sdk).<br /><br />
<div>require recipes-extended/images/core-image-full-cmdline.bb</div>
<div>&nbsp;</div>
<div>IMAGE_INSTALL_append = " \</div>

<div>&nbsp;</div>
<div>TOOLCHAIN_HOST_TASK_append = " nativesdk-perl-modules"</div>

Any help on resolving this issue would be greatly appreciated.<br /><br />Thanks.<br />-- <br /><br />Rob
