> However, that alone did not solve the issue. I had to remove the calls `exec_ctores()` and `atexit(exec_dtors)` from `crt0.c` in order to not crash on ELF load. exec_ctors() is really simple, but it depends on a table of constructor addresses created by the build logic. These are defined by binfmt/libelf/gnu-elf.ld or similar: ``` /* Linker defined symbols to .ctors and .dtors */ extern initializer_t _sctors[]; extern initializer_t _ectors[]; extern initializer_t _sdtors[]; extern initializer_t _edtors[]; ``` Check whatever linker script you use to build the elf modules. Check that those symbols exist in the module. These define a table of constructor destructor address. Constructors start at _sctors and end at _ectors. Make sure that there are constructors in the table. Issues with atexit() may be like those of #1263. I don't know the state of that. > Regardless, I can live with NuttX kernel build that has no C++ static constructor support given everything else appears to be working flawlessly.
