Hi Justin,
I was assuming you were planning to run it from "nsh>" that is working fine:
nsh> ?
help usage: help [-v] [<cmd>]
. cp exec ls reboot truncate
[ cmp exit mkdir rm uname
? dirname expr mkrd rmdir umount
alias date false mount set unset
unalias dd fdinfo mv sleep uptime
basename df free pidof source usleep
break dmesg help printf test xd
cat echo hexdump ps time
cd env kill pwd true
Builtin Apps:
custom_hello hello ostest
getprime nsh sh
nsh> custom_hello
Custom Hello
nsh>
So, probably you forgot to go: make menuconfig => Applications
Configuration -> Custom Apps -> [*] Custom Hello.
However I found an intriguing fact, when I use
CONFIG_INIT_ENTRYPOINT="hello_main" I get it working fine and I see in the
minicom:
Hello, World!!
But, when I changed to CONFIG_INIT_ENTRYPOINT="custom_hello_main" I get
this compilation error:
$ make
CC: CustomHello.c <command-line>: error: conflicting types for
'custom_hello_main'
CustomHello.c:3:5: note: in expansion of macro 'main'
3 | int main(void)
| ^~~~
In file included from /home/alan/nuttxspace/nuttx/include/stdio.h:28,
from CustomHello.c:1:
/home/alan/nuttxspace/nuttx/include/sys/types.h:337:5: note: previous
declaration of 'custom_hello_main' was here
337 | int CONFIG_INIT_ENTRYPOINT(int argc, FAR char *argv[]);
| ^~~~~~~~~~~~~~~~~~~~~~
make[2]: *** [/home/alan/nuttxspace/apps/Application.mk:289:
CustomHello.c.home.alan.nuttxspace.apps.CustomApps.CustomHello.o] Error 1
make[1]: *** [Makefile:51:
/home/alan/nuttxspace/apps/CustomApps/CustomHello_all] Error 2
make: *** [tools/LibTargets.mk:232: /home/alan/nuttxspace/apps/libapps.a]
Error 2
After some investigation I found the root cause, the main was defined this
way:
int main(void)
{
printf("Custom Hello\n");
return 0;
}
So, it was generation conflict, then after changing to:
int main(int argc, FAR char *argv[])
{
printf("Custom Hello\n");
return 0;
}
Everything worked as expected and I got it on minicom:
Custom Hello
I will submit a patch to fix this example, thank you very much!
BR,
Alan
