digitalmars.D.learn - Building dmd/druntime on windows issue

Hi,

I follow the instructions from the wiki to build dmd/druntime 
from source on windows.
https://wiki.dlang.org/Building_under_Windows

Building dmd ends with following text:

-------------------
copy ..\generated\windows\release\32\dmd.exe .
         1 file copied.


make -fwin32.mak C=dmd\backend TK=dmd\tk ROOT=dmd\root 
MAKE="make" HOST_DC="dmd" MODEL=32 CC="dmc" LIB="lib" OBJ_MSVC="" 
clean
rmdir /s /q ..\generated
del dmd\msgs.h dmd\msgs.c
C:\D\dmd2\src\dmd\src\dmd\msgs.h cannot be found
del optabgen.exe parser_test.exe example_avg.exe
del ..\generated\windows\release\32\dmd.exe 
..\generated\windows\release\32\dmd_frontend.exe *.map *.obj *.exe
The system cannot find the given path.
-------------------

If my understanding is correct, there are several issues:
- File dmd\msgs.h does not exist
- make deletes path "generated" which is needed in a further step.

There is a file "C:\D\dmd2\src\dmd\src\dmd.exe" created which 
seems to be the build result.

If I now try to build druntime it also fails, because the path 
"generated" does not exist:

-----------------------
..\dmd\generated\windows\release\32\dmd -conf= -c -o- -Isrc 
-Iimport -Hfimport\core\sync\barrier.di src\core\sync\barrier.d
Error: '..\dmd\generated\windows\release\32\dmd' not found
-----------------------

Kind regards
André

Which DMD/druntime do you try to build?
IIRC there are some issues with the release ball, you should try 
the GitHub sources.
Also are you using DigitalMars make?
What environment variables did you set?

I cloned the sources (dmd, runtime ,...) yesterday from github 
and tried to build the master branches. I used the suggested 
paths and environment variables from the wiki (DM_HOME, HOST_DC). 
Also make from Digital Mars was used. In tried to follow the 
instructions exactly.

Kind regards

I am pretty sure now the WIKI is wrong. The argument "release" in 
command:
make -fwin32.mak release
will by intentional delete the folder "generated"
https://github.com/dlang/dmd/blob/master/src/win32.mak#L347

But this folder is needed for building druntime as described in 
wiki chapter "Building D runtime".

I somehow solved the issue by calling make without the "release" 
argument.
Either the WIKI needs to be adapted or the make script.

Kind regards
