When building a 64-bit multilib SDK the links to 32-bit libraries are not being installed.
Manually create the required links.
$ configure --enable-board=qemux86_64 --enable-kernel=cgl --enable-rootfs=glibc_cgl $ make export-sdk NOTE: before building, ensure that the 32-bit libraries you need are enabled, for example you should add lin32-openssl. This can be done through a template containing this line: IMAGE_INSTALL_append += "lib32-openssl" Install the SDK then check for the library: $ cd /path/to/sdk $ find . -name 'libcrypto*' ./sysroots/qemux86_64-wrs-linux/usr/lib64/pkgconfig/libcrypto.pc ./sysroots/qemux86_64-wrs-linux/lib64/.debug/libcrypto.so ./sysroots/qemux86_64-wrs-linux/lib64/.debug/libcrypto.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/lib64/libcrypto.so ./sysroots/qemux86_64-wrs-linux/lib64/libcrypto.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/lib/.debug/libcrypto.so ./sysroots/qemux86_64-wrs-linux/lib/.debug/libcrypto.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/lib/libcrypto.so.1.0.0 Notice lib64/libcrypto.so is a symlink to lib64/libcrypto.so.1.0.0 but there is no corresponding 32-bit link to lib/libcrypto.so.1.0.0 This is true also with libssl: $ find . -name 'libssl*' ./sysroots/qemux86_64-wrs-linux/usr/lib64/libssl.so ./sysroots/qemux86_64-wrs-linux/usr/lib64/pkgconfig/libssl.pc ./sysroots/qemux86_64-wrs-linux/usr/lib64/.debug/libssl.so ./sysroots/qemux86_64-wrs-linux/usr/lib64/.debug/libssl.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/usr/lib64/libssl.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/usr/lib/.debug/libssl.so ./sysroots/qemux86_64-wrs-linux/usr/lib/.debug/libssl.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/usr/lib/libssl.so.1.0.0 ./sysroots/qemux86_64-wrs-linux/lib64/.debug/libssl3.so ./sysroots/qemux86_64-wrs-linux/lib64/libssl3.so
