Problems with Quickfix list

Question

I am trying to make makeprg so that when I write :make it will compile my c program and if there are problems put them in Quickfix list and if there are non run the program and put output to Quick fix list

I am using

vim 9.0
zsh
g++ compiler on m1 mac
in alacrity emulator

this works but it doesn't execute the code:

set makeprg=g++\ -w\ -g\ %\ -o\ %:r

when I try this one:

CompilerSet makeprg=rm\ -fr\ %:r;g++\ -w\ -g\ %\ -o\ %:r&&./%:r

it goes like this:

(I have errors in my code) it shows me the errors then I hit enter I get blank screen with :

E40: Can't open error file /var/folders/hc/y4sccdy52y34th77l1lc0j_c0000gn/T/vTqwygm/3

(last three folders change every run)

then I hit another enter return to vim and contents of Quickfix list is unchanged.

when I remove the error:

output of ./%:r is shown with no problems.

I added :

rm\ -fr\ %:r

because I thought that if there will be no executable to run for ./%:r it will not show in Quick fix

without that it always shows output of

rm\ -fr\ %:r

any help is much appreciated

BTW, why are you compiling C with the C++ compiler `g++` instead of using `gcc`? — Friedrich, Jul 03 '23 at 09:09
I don't know is there any diference? or reason to use gcc? if so could you send me some article or video? — Tomas barta, Jul 03 '23 at 09:52

Vim is redirecting the output from makeprg to a file, hence the error: there is no output from ./%:r.

When you want run multiple commands, the output will be taken from the last one. Instead you need to create a subshell to run both commands, so the output of both is combined together:

set makeprg=(g++\ -w\ -g\ %\ -o\ %:r\ &&\ ./%:r)
