Since version 4.10.0 the waf build system does not correctly take the values from the cross answers file when configuring for the target machine, resulting in wrong values, e.g.: ``` Checking for rpath library support : not found ``` Looking into sambas config.log shows that the check for rpath library support aborts because of in internal exception. The result is that the shared library libsmbclient.so does not have a correct rpath section in its ELF header: ``` Library rpath: [/usr/lib] ``` This is incorrect, as libsmbclient links to secondary libraries located in /usr/lib/samba. When linking mpd (with libsmbclient feature enabled) against libsmbclient, the linker does not find the secondary libraries for libsmbclient and fails with: ``` /usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/powerpc64le-buildroot-linux-gnu/7.4.0/../../../../powerpc64le-buildroot-linux-gnu/bin/ld: warning: libcli-ldap-common-samba4.so, needed by /usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/usr/bin/../powerpc64le-buildroot-linux-gnu/sysroot/usr/lib/libsmbclient.so, not found (try using -rpath or -rpath-link) [skip] /usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/powerpc64le-buildroot-linux-gnu/7.4.0/../../../../powerpc64le-buildroot-linux-gnu/bin/ld: /usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/usr/bin/../powerpc64le-buildroot-linux-gnu/sysroot/usr/lib/libsamdb.so.0: undefined reference to `sec_privilege_id' [skip] ``` The bug has been reported upstream [1]. Setting `WAF_NO_PREFORK=1` fixes the internal exception by disabling the usage of pre-forked processes which somehow fails in cross-compiling environment. Now, the configuration takes the correct values from the cross answers file: ``` Checking for rpath library support : yes ``` And leads to a correct rpath entry in the ELF header: ``` Library rpath: [/usr/lib/samba:/usr/lib] ``` And fixes the build of with libsmbclient feature enabled.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
