Severity: Standard
Applicable for: Wind River Linux LTS 21
Component/s: Build & Config
When building the gcc crosscompiler on a machine that has libzstd installed, the cross compiler detects this and links towards this library. Then when the sstate object is being resused on a machine that does not have libzstd installed, the cross compiler is not usable because of this:
On machine with libzstd:
$ ldd cc1
...
libzstd.so.1 => /lib64/libzstd.so.1 (0x00007f0f0c5e0000)
libstdc+{+}.so.6 => /lib64/libstdc{+}+.so.6 (0x00007f0f0c24b000)
...
On machine without libzstd:
$ ldd cc1
...
libz.so.1 => /wrl21/build/mib-axm5612-standard_rootfs/./build/tmp-glibc/work/armv7at2-neon-wrs-linux-gnueabi/glibc/2.33-r0.xcs2/recipe-sysroot-native/usr/libexec/arm-wrs-linux-gnueabi/gcc/arm-wrs-linux-gnueabi/10.3.0/../../../../../lib/libz.so.1 (0x00007fe5cc14d000)
