# Summary This adds exported LDMODULEFLAGS so that kernel modules can build with Kernel mode NuttX. Without it, we have link errors like: ```sh make[3]: Entering directory '/tmp/apps/examples/module/chardev' LD: /tmp/apps/bin/chardev arm-none-eabi-ld: warning: cannot find entry symbol _start; defaulting to 0000000000008000 arm-none-eabi-ld: chardev.c.tmp.apps.examples.module.chardev.o: in function `module_uninitialize': /tmp/apps/examples/module/chardev/chardev.c:111: undefined reference to `unregister_driver' arm-none-eabi-ld: chardev.c.tmp.apps.examples.module.chardev.o: in function `module_initialize': /tmp/apps/examples/module/chardev/chardev.c:129: undefined reference to `register_driver' arm-none-eabi-ld: /tmp/apps/import/startup/crt0.o: in function `__start': /tmp/nuttx/arch/arm/src/armv7-a/crt0.c:133: undefined reference to `main' make[3]: *** [/tmp/apps/Application.mk:308: /tmp/apps/bin/chardev] Error 1 ``` It also stops exporting LDELFFLAGS as it contains NuttX side paths: ```sh $ fgrep LDELFFLAGS apps/import/scripts/Make.defs LDELFFLAGS = -e main -T /tmp/nuttx/libs/libc/modlib/gnu-elf.ld ``` By design, exported SDK shall not refer to NuttX folder any more, and the link scripts under `apps/import/` should suffice. # Impacts Projects using export SDK # Testing - local checks with EXAMPLES_MODULE enabled qemu-armv7a:nsh and qemu-armv7a:knsh - CI checks -- This is an automated message from the Apache Git Service.
