Created attachment 193356 [details] virtualbox-ose.diff Hi, it seems that virtualbox-ose attempts to link statically with some libraries. This fails on 12.0-CURRENT/amd64 (r333416) with DEFAULT_VERSIONS=ssl=libressl in make.conf: kBuild: Linking VBoxCpuReport /usr/bin/ld: error: duplicate symbol: arc4random >>> defined at arc4random.o:(arc4random) in archive /usr/local/lib/libcrypto.a >>> defined at arc4random.c:223 (/usr/src/lib/libc/gen/arc4random.c:223) >>> arc4random.o:(.text+0x6D0) in archive /usr/lib/libc.a /usr/bin/ld: error: duplicate symbol: arc4random_buf >>> defined at arc4random.o:(arc4random_buf) in archive /usr/local/lib/libcrypto.a >>> defined at arc4random.c:235 (/usr/src/lib/libc/gen/arc4random.c:235) >>> arc4random.o:(.text+0xAE0) in archive /usr/lib/libc.a /usr/bin/ld: error: duplicate symbol: arc4random_uniform >>> defined at arc4random_uniform.o:(arc4random_uniform) in archive /usr/local/lib/libcrypto.a >>> defined at arc4random.c:259 (/usr/src/lib/libc/gen/arc4random.c:259) >>> arc4random.o:(.text+0x1110) in archive /usr/lib/libc.a c++: error: linker command failed with exit code 1 (use -v to see invocation) kmk: *** [/wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/obj/VBoxCpuReport/VBoxCpuReport] Error 1 The failing command: @c++ '-Wl,-rpath,/usr/local/lib/virtualbox' -static -m64 -o /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/obj/VBoxCpuReport/VBoxCpuReport /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/obj/VBoxCpuReport/VBoxCpuReport.o /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/obj/VBoxCpuReport/VBoxCpuReportMsrSup.o /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/obj/VBoxCpuReport/dt/VMMR3/CPUMR3CpuId.o -L/usr/local/lib /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/lib/SUPR3Static.a /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/lib/RuntimeR3.a /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/lib/RuntimeR3.a /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.2.12/out/freebsd.amd64/release/lib/VBox-liblzf.a -lz -lpthread -lssl -lcrypto *** Error code 2 The attached patch adds FreeBSD to the list of platforms where this is not allowed. (It seems the last update did not regenerate the patches, so sorry for the extra noise in the patch.)
