When OpenSSL is enabled, if DES support is enabled, OpenSSH uses DES_crypt. However, without OpenSSL or its DES support, there is no available crypt() implementation for OpenSSH libopenbsd-compat xcrypt() function, resulting in the following error: .../host/bin/i686-buildroot-linux-gnu-gcc -o sshd-auth sshd-auth.o auth2-methods.o auth-rhosts.o auth-passwd.o sshpty.o sshlogin.o servconf.o serverloop.o auth.o auth2.o auth-options.o session.o auth2-chall.o groupaccess.o auth-bsdauth.o auth2-hostbased.o auth2-kbdint.o auth2-none.o auth2-passwd.o auth2-pubkey.o auth2-pubkeyfile.o auth2-gss.o gss-serv.o gss-serv-krb5.o monitor_wrap.o auth-krb5.o audit.o audit-bsm.o audit-linux.o platform.o loginrec.o auth-pam.o auth-shadow.o auth-sia.o sandbox-null.o sandbox-rlimit.o sandbox-darwin.o sandbox-seccomp-filter.o sandbox-capsicum.o sandbox-solaris.o sftp-server.o sftp-common.o uidswap.o ssh-pkcs11-client.o ssh-sk-client.o -L. -Lopenbsd-compat/ -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -g0 -D_FORTIFY_SOURCE=1 -Wl,-z,relro -Wl,-z,now -Wl,-z,noexecstack -fstack-protector-strong -pie -lssh -lopenbsd-compat -L.../host/bin/../i686-buildroot-linux-gnu/sysroot/usr/lib -lssl -lcrypto -lcrypto -lz .../host/lib/gcc/i686-buildroot-linux-gnu/15.3.0/../../../../ i686-buildroot-linux-gnu/bin/ld: openbsd-compat//libopenbsd-compat.a(xcrypt.o): in function `xcrypt': xcrypt.c:(.text+0x51): undefined reference to `crypt' .../host/lib/gcc/i686-buildroot-linux-gnu/15.3.0/../../../../ i686-buildroot-linux-gnu/bin/ld: openbsd-compat//libopenbsd-compat.a(xcrypt.o): in function `xcrypt': xcrypt.c:(.text+0x51): undefined reference to `crypt' collect2: error: ld returned 1 exit status make[2]: *** [Makefile:233: sshd-auth] Error 1 make[2]: *** Waiting for unfinished jobs.... collect2: error: ld returned 1 exit status make[2]: *** [Makefile:230: sshd-session] Error 1 make[1]: *** [package/pkg-generic.mk:273: .../build/openssh-10.4p1/.stamp_built] Error 2 make: *** [Makefile:83: _all] Error 2 This commit enables BR2_PACKAGE_LIBXCRYPT with OpenSSH as long as glibc is used. Since "sshd-auth" is compiled regardless of BR2_PACKAGE_OPENSSH_SERVER, we need to enable it with BR2_PACKAGE_OPENSSH.

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 https://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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
