**The problem is I already put lcd.h in r_main.c's tree(as firgure 1),
and when I even press "Ctrl"+"Click left mouse" at "lcd.h" word in "#include "lcd.h" of my code, it can open file lcd.h!
but when compiler it(Build All),
error is: make -j4 all 'Scanning and building file: ../src/r_main.c''Invoking: Scanner and Compiler'../src/r_main.c:40:17: fatal error: lcd.h: No such file or directory #include "lcd.h" ^compilation terminated.make: *** [src/r_main.o] Error 1src/subdir.mk:155: recipe for target 'src/r_main.o' failedcompilation terminated.
I also tried this solution in link: https://renesasrulz.com/e2studio/f/e2studio-forum/5022/stdbool-h-no-such-file-or-directory-include-stdbool-h
But it did not work.
1. In case you are using e2 studio, please select Newlib library via Project > Properties > Settings : Tool Settings > Library Generator > Settings > Select library : Newlib 2. Click Apply and OK.
Is lcd.h included in the project? Is the folder that includes lcd.h in included in the preprocessor include settings?
When using the RL78 code generator I recommend to put all of your own files into a different folder than src. Leave the src folder for generated code only.
