Trying to use VSCode with existing project

[elgerg]

Hi,

Ive been using Eclipse to use the simulator for a while with no issues on v7.

I want to use v8 and the simulator on vscode.

I cloned the project and ran the demo no problem. However once I linked my app folder to:

lv_sim_vscode_sdl/App

Edited the main.c file to look like

include "lvgl/lvgl.h"

//#include "lvgl/examples/lv_examples.h" //#include "lv_examples/lv_demo.h"

include "lv_drivers/display/monitor.h"

include "lv_drivers/indev/mouse.h"

include "lv_drivers/indev/keyboard.h"

include "lv_drivers/indev/mousewheel.h"

include "App/App.h"

and // lv_example_flex_3(); // lv_example_label_1();

lv_loadTabs();

//lv_demo_widgets(); // lv_demo_keypad_encoder(); // lv_demo_benchmark(); // lv_demo_stress(); // lv_demo_music();

I get the following errors on buiild/run: ./App/Tasks/Tasks.h:9:16: error: unknown type name ‘lv_task_t’; did you mean ‘lv_bar_t’? 9 | void tsk_temps(lv_task_t task); | ^~~~~ | lv_bar_t In file included from main/src/main.c:23: ./App/App.h:164:1: error: unknown type name ‘lv_task_t’; did you mean ‘lv_bar_t’? 164 | lv_task_t TempsTask; | ^~~~~ | lv_bar_t make: *** [Makefile:47: build/obj/main/src/main.o] Error 1 The terminal process "bash '-c', 'make'" terminated with exit code: 2.

Is this because lv_task_t doesnt exist in v8 or do I have another issue? Am I going about it in the right way or is there a better way of linking in my app?

Thanks in advance Alex

ok, it looks like tasks have been replaced with timers? Ive managed to get past that problem.

Now the issue I a getting is that my entry point is not defined: /usr/bin/ld: ./build/obj/main/src/main.o: in function main': /home/pi/Documents/lv_sim_vscode_sdl/main/src/main.c:99: undefined reference tolv_loadTabs' collect2: error: ld returned 1 exit status make: *** [Makefile:51: default] Error 1 The terminal process "bash '-c', 'make'" terminated with exit code: 2.

It looks like my "App" folder is not being built. I thought amending the make file like so would fix this: INC := -I./ui/simulator/inc/ -I./ -I./lvgl/ -I./App/

What do I need to alter to make it build the App subfolder?

Thanks Alex

I did think it might be to do with this:

shell find $(SRC_DIR) -type f -name '.c' -not -path '/.*'

I assume "-type f" is folder? I have simlinked the App folder to this folder as it's used in multiple projects).

Any advice would be appreciated. Alex

-type f is file (where -type d is directory). This should find all .c files in the $SRC_DIR which as default is set to "./". You can run this as a command in a shell to see which files it finds. Change directory to where the makefile is placed and run this.

find ./ -type f -name '*.c' -not -path '*/\.*'

And see what it gives you. I believe the problem is that you have symlinked the folder, you could try using the -L option of find and see if that helps?

[elgerg]

Ok, its deffo to so with the Symlnked folder.

If i remove the link and copy the folder in i get the expected errors due to the upgrade from 7.5 to 8.

Any ideas how to get the find to traverse the links?

Thanks Alex

As mentioned above try adding -L to the find command. This should get it to traverse symlinks. Try running this from the command line.

find -L ./ -type f -name '*.c' -not -path '*/\.*'

If it works add the -L to the makefile command

[elgerg]

I did try:

SRCS := $(shell find $(SRC_DIR) -type f,l -L -name '.c' -not -path '/.*')

But got:

find: unknown predicate -L' cc -o ./build/bin/demo -lSDL2 -lm /usr/bin/ld: /usr/lib/gcc/aarch64-linux-gnu/10/../../../aarch64-linux-gnu/Scrt1.o: in function_start': (.text+0x18): undefined reference to main' /usr/bin/ld: (.text+0x1c): undefined reference tomain' collect2: error: ld returned 1 exit status make: *** [Makefile:51: default] Error 1

[elgerg]

Running:

find $(./) -L -type f,l -name '*.c'

on the command line did work, just not in make.

[elgerg]

ok, that worked:

SRCS := $(shell find -L $(SRC_DIR) -type f,l -name '.c' -not -path '/.*')

seems it required the -L to be in the right place..

[microwavesafe]

I'm glad it worked, can I close this issue?

[elgerg]

Sure.
