9832 :: `--os:standalone` gives `Error: system module needs: getCurrentException`

• thisago (orginal) [2023-01-19T20:21:10+01:00] view original

  Shalom, I was using the nim-platformio and when I import strformat gives the error: Error: system module needs: getCurrentException

  works

  
  import pkg/arduino
  
  setup:
    pinMode(LED_BUILTIN, OUTPUT)
  
  loop:
    digitalWrite(LED_BUILTIN, HIGH)
    delay(1000)
    digitalWrite(LED_BUILTIN, LOW)
    delay(1000)
  Run

  but when I add this, it doesn't works

  
  from std/strformat import fmt
  
  static:
    echo fmt"""Hello {"World"}"""
  Run

  the nim-platformio platformio dependency compiles the nim with: nim cpp --path:/path/to/project/.pio/libdeps/nanoatmega328 --nimcache:/path/to/project/src/nimcache --compileOnly --cpu:avr --deadCodeElim --os:standalone --noMain --gc:none --stacktrace:off --profiler:off /path/to/project/src/main

  Any lib that uses getCurrentExceptionMsg gives this error, there's a way to declare a own getCurrentExceptionMsg that works in embedded?

  Maybe related: https://github.com/nim-lang/Nim/issues/16404

  But when using --gc:arc --os:any -d:StandaloneHeapSize=1048576, the error is:

  
  src/nimcache/stdlib_system.nim.cpp:6:10: fatal error: exception: No such file or directory
   #include <exception>
            ^~~~~~~~~~~
  compilation terminated.
  *** [.pio/build/nanoatmega328/src/nimcache/stdlib_system.nim.cpp.o] Error 1

  and when compiled with --gc:arc --os:any -d:useMalloc, the error is:

  
  src/nimcache/stdlib_system.nim.cpp:6:10: fatal error: exception: No such file or directory
   #include <exception>

  Maybe also --panics:on?

---

• thisago (orginal) [2023-01-19T21:54:02+01:00] view original

  With --panics:on -d:useMalloc --os:any --gc:arc gives the same error:

  
  src/nimcache/stdlib_system.nim.cpp:6:10: fatal error: exception: No such file or directory
   #include <exception>
            ^~~~~~~~~~~
  compilation terminated.

  and same with --panics:on -d:StandaloneHeapSize=1048576 --os:any --gc:arc too:

  I tried stable Nim and same, but with the devel version, the error is different:

  
  /home/user/.choosenim/toolchains/nim-#devel/lib/pure/unicode.nim(849, 36) Error: type mismatch: got 'int32' for 'RuneImpl(toLower(ar)) - RuneImpl(toLower(br))' but expected 'int'
  Run

  The type mismatch error on devel is probably related to https://github.com/nim-lang/Nim/pull/20829

  src/nimcache/stdlib_system.nim.cpp:6:10: fatal error: exception: No such file or directory > #include <exception>

  You could try --exceptions:goto and see if it works better.

  I ran into a similar issue yesterday wrapping some C++ code with Nim that re-defined exception in the current namespace.

  In your case, it looks like the settings from platformio plugin sets or pulls in --exceptions:cpp. A quick Google search seems to show that at least some Arduino platforms compile using the C++ cflags -fno-exceptions. That would disable C++ exceptions.

  The new switch people should use instead of os:standalone is os:ansic.

---

• galaxyDragon (orginal) [2023-01-20T11:26:04+01:00] view original

  Try these options ? ,

  --os:any --gc:arc -d:useMalloc --exceptions:goto

  -d:noSignalHandler

---

• thisago (orginal) [2023-01-20T13:01:13+01:00] view original

  I tried --os:ansic instead of --os:standalone, but it gives: command line(1, 2) Error: unknown OS: 'ansic'. Available options are: DOS, Windows, OS2, Linux, MorphOS, SkyOS, Solaris, Irix, NetBSD, FreeBSD, OpenBSD, DragonFly, CROSSOS, AIX, PalmOS, QNX, Amiga, Atari, Netware, MacOS, MacOSX, iOS, Haiku, Android, VxWorks, Genode, JS, NimVM, Standalone, NintendoSwitch, FreeRTOS, Zephyr, Any

  and I updated the devel with choosenim but the error persists

  I tried with this parameters in devel, but the error is same as above type mismatch, but when I tried the version 1.6.10, the nim was compiled to cpp, but in linking, gave this:

  Oh thank you very much! this fixed! I tried clean command but not deleting the nimcache, tnx!

  This is just information.

  I've added Serial class to nim-platformio project.
