I'm basically compiling for ARM Cortex-M7 (stm32f769 discovery board). What I have additionally spotted is that mosquiotto_sub doesn't crash with same error, but it doesn't have ssl options working. So probably my first problem is that libopenssl doesn't compile properly... When I try to compile it separately, by using make libopenssl-reconfigure it seems that it doesn't have target architecture defined. If I add BR2_PACKAGE_TARGET_ARCH="arm-v4" to make call, I end up in error of missing file (it's also weird why win32 files are included in compilation at all) : /home/robi/Razvoj/Linux/Buildroot/JE_UcLinux/buildroot/../host/bin/arm-build root-uclinux-uclibcgnueabi-gcc -I. -Iinclude -fPIC -pthread -Wa,--noexecstack -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -Wl,-elf2flt -static -DHAVE_FORK=0 -DOPENSSL_NO_MADVISE -DOPENSSL_NO_ASYNC -Wl,-elf2flt -static -DOPENSSL_USE_NODELETE -DOPENSSL_PIC -DOPENSSL_CPUID_OBJ -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DKECCAK1600_ASM -DAES_ASM -DBSAES_ASM -DGHASH_ASM -DECP_NISTZ256_ASM -DPOLY1305_ASM -DOPENSSLDIR="\"/etc/ssl\"" -DENGINESDIR="\"/usr/lib/engines-1.1\"" -DZLIB -DNDEBUG -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -MMD -MF crypto/dso/dso_win32.d.tmp -MT crypto/dso/dso_win32.o -c -o crypto/dso/dso_win32.o crypto/dso/dso_win32.c crypto/dso/dso_dlfcn.c:28:12: fatal error: dlfcn.h: No such file or directory # include ^~~~~~~~~ compilation terminated. Any advice where I can learn or get libopenssl compiled properly? Then I can proceed to mosquitto, because it uses libopenssl. I'm probably doing something obviously wrong... I'm using buildroot release tag 2020.05...

If the problem still exists after a full rebuild please provide your .config or defconfig file and the buildroot version your are using...
