Thanks Gustavo sorry for late replay..
Why are not all these flags and the correct ld.tmp files exported when we generate the nuttx-export file?
It will be corrected in the future or do we modify our files that automatically generate nuttx binaries to this?
Thanks again Roberto On 1/5/23 14:52, Gustavo Henrique Nihei wrote:
Hi Roberto, Since https://github.com/apache/nuttx/pull/7208 the NuttX build system preprocesses every linker script file of a given configuration. We've recently updated the makefiles and linker scripts of every supported chip from the ESP32 family to benefit from this. So you may need to update your out-of-tree build system to also preprocess each linker script file (e.g. using "-E" argument from GCC) and pass the output files to xtensa-esp32-elf-ld. Notice that you'll need to provide all the include paths to GCC so that it is able to find the headers required at the processing phase. As a reference, if you build "esp32-devkitc:nsh" with "make V=1", you'll notice that for each ".ld" file the build system will generate a new one suffixed with ".ld.tmp", which are the ones to be passed to the Linker: *CPP: /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/esp32_rom.ld-> /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/esp32_rom.ld.tmp xtensa-esp32-elf-gcc -E -P -x c -isystem /home/nihei/Projects/NuttX/nuttx/include -D__NuttX__ -DNDEBUG -D__KERNEL__ -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/chip -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/common -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/lx6 -I /home/nihei/Projects/NuttX/nuttx/sched /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/esp32_rom.ld -o /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/esp32_rom.ld.tmp* *CPP: /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/flat_memory.ld-> /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/flat_memory.ld.tmpxtensa-esp32-elf-gcc -E -P -x c -isystem /home/nihei/Projects/NuttX/nuttx/include -D__NuttX__ -DNDEBUG -D__KERNEL__ -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/chip -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/common -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/lx6 -I /home/nihei/Projects/NuttX/nuttx/sched /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/flat_memory.ld -o /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/flat_memory.ld.tmp* *CPP: /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/legacy_sections.ld-> /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/legacy_sections.ld.tmp xtensa-esp32-elf-gcc -E -P -x c -isystem /home/nihei/Projects/NuttX/nuttx/include -D__NuttX__ -DNDEBUG -D__KERNEL__ -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/chip -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/common -I /home/nihei/Projects/NuttX/nuttx/arch/xtensa/src/lx6 -I /home/nihei/Projects/NuttX/nuttx/sched /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/legacy_sections.ld -o /home/nihei/Projects/NuttX/nuttx/boards/xtensa/esp32/esp32-devkitc/../common/scripts/legacy_sections.ld.tmp* Best regards, Gustavo.
