VS can see include file but compiler can't open it

[odd topaz]

I posted yesterday and seemed to fix my issue but alas... I'm getting C1083 "cannot open include file" when compiling, but VS displays the file when auto-completing the #include & it's included in 'External Dependencies' folder where i can open & view it.

Have tried vcpkg, nuget, manually including and reinstalling VS. Only time it hasn't gotten stuck is when I include the full file location but it then gets stuck on it's own include files.

show where yoi added the deps

[odd topaz]

This is from the manual inclusion, have tried every 'Include' line I can find in properties

[atomic coyote]

show how the path evluates

its on the right side

the 3 dots

[atomic coyote]

put the include as first one

so i can see evaluated value

[atomic coyote]

okay now show compiler error

the output tab

[atomic coyote]

first, set c++ to 17

[odd topaz]

Set both projects to use c++ 17 under language

[atomic coyote]

wait a sec

do both projects have same include dir

So I've got NetCommon which is headers-only wrapping everything to do with asio, then NetClient includes the NetCommon headers to run a script - which appears to be working the only errors are back at the NetCommon #include asio

I'll add a cpp file to NetCommon to see if it'll work in only that project

[atomic coyote]

i mean it looks like the issuebis in netcommon

add the include dir to that project too

also idk whats the point of a whole projects for header only files

just make a directory

[odd topaz]

following a tut to get my head around this stuff

thats NetClient set up with both include directiories

[atomic coyote]

but is the netcommon containing the include dir

not asking about net client

the issue is on netcommon

[odd topaz]

yeah yeah, all the earlier screenshots are from Netcommon

made a whole new project with the h and cpp files all in one and it seems to be working... maybe I've messed something up when creating the project or it just doesn't like working cross-projects

I'll go away and copy all the code over to a brand new project set up like this and see what happens

[modern harbor]

unfortunately too easy to miss (or mess this up)
the standard (imo) is to put additional folders into C/C++ - General - Additional include directories
not in the global VC++ Directories

[atomic coyote]

i dont believe so

[odd topaz]

holy moley I fixed it...somehow. Made a whole new project and all. It seems like the NetClient also needed to have the library as an included directory but I definitely tried that, so possibly I'd messed something else up along the way. But it was definitely giving me the wrong error for what the problem actually was

ah well, back to actually coding, thanks for the help team
