I tried to create a rootfs with the attached defconfig (using buildroot toolchain). In the resulting rootfs the glibc is missing. There are symlinks but the actual library is missing. In the host directory everything is fine but not in the resulting image. This is the case for the tar and the squashfs image. Other images I did not test. ls -l /lib lrwxrwxrwx 1 root root 10 Sep 29 08:57 ld-linux.so.3 -> ld-2.25.so lrwxrwxrwx 1 root root 14 Sep 29 08:57 libanl.so.1 -> libanl-2.25.so lrwxrwxrwx 1 root root 18 Sep 29 08:57 libatomic.so -> libatomic.so.1.2.0 lrwxrwxrwx 1 root root 18 Sep 29 08:57 libatomic.so.1 -> libatomic.so.1.2.0 -rwxr-xr-x 1 root root 21652 Sep 28 17:16 libatomic.so.1.2.0 lrwxrwxrwx 1 root root 16 Sep 29 08:57 libcrypt.so.1 -> libcrypt-2.25.so lrwxrwxrwx 1 root root 12 Sep 29 08:57 libc.so.6 -> libc-2.25.so lrwxrwxrwx 1 root root 13 Sep 29 08:57 libdl.so.2 -> libdl-2.25.so -rw-r--r-- 1 root root 132 Sep 28 17:01 libgcc_s.so -rw-r--r-- 1 root root 124448 Sep 28 17:16 libgcc_s.so.1 lrwxrwxrwx 1 root root 12 Sep 29 08:57 libm.so.6 -> libm-2.25.so lrwxrwxrwx 1 root root 14 Sep 29 08:57 libnsl.so.1 -> libnsl-2.25.so lrwxrwxrwx 1 root root 18 Sep 29 08:57 libnss_dns.so.2 -> libnss_dns-2.25.so lrwxrwxrwx 1 root root 20 Sep 29 08:57 libnss_files.so.2 -> libnss_files-2.25.so lrwxrwxrwx 1 root root 18 Sep 29 08:57 libpthread.so.0 -> libpthread-2.25.so lrwxrwxrwx 1 root root 17 Sep 29 08:57 libresolv.so.2 -> libresolv-2.25.so lrwxrwxrwx 1 root root 13 Sep 29 08:57 librt.so.1 -> librt-2.25.so lrwxrwxrwx 1 root root 19 Sep 29 08:57 libthread_db.so.1 -> libthread_db-1.0.so lrwxrwxrwx 1 root root 15 Sep 29 08:57 libutil.so.1 -> libutil-2.25.so
Created attachment 7246 [details] My defconfig
Alex, I can't reproduce here, the C library is correctly installed in target/ and present in both images. In case you changed the toolchain configuration after a previous build, be sure to start from scratch: make clean; make (see the manual: http://buildroot.net/downloads/manual/manual.html#_full_rebuild) If you still have the issue, then please re-open. Regards, Yann E. MORIN.
I was building it in a fresh docker container every time. But you are right. When I did a clean build the problem is gone. I just replaced "make" with "make clean all" Thanks for your effords!
