--- Comment #3 from Seb <greensunny12 at gmail.com> ---
BTW guys I just built the GNUmake exe via AppVeyor in case someone is looking
for this:

https://issues.dlang.org/show_bug.cgi?id=18658
https://github.com/dlang/installer/pull/311
https://ci.appveyor.com/project/greenify/installer-gqmr6/build/1.0.16/artifacts

So far my steps for reproducing everything under Wine:

---
wget http://downloads.dlang.org/releases/2.x/2.079.0/dmd-2.079.0.exe
wine dmd-2.079.0.exe
---

(install dmc too)

Then export these variables:

---
export DM_HOME=C:/D
export HOST_DC=dmd
export WINEPATH="C:\DMC\dm\bin\;C:\D\dmd2\windows\bin"
---

With this I can build everything under Wine:

---
cd dmd
wine make -f win32.mak
cd ../druntime
wine make -f win32.mak
cd ../phobos
wine make -f win32.mak
---

Now for the testsuite. Here are my attempts:

---
cd dmd/test
wget
https://ci.appveyor.com/api/buildjobs/twy5nix34sn0329n/artifacts/gmake-4.2.zip
unzip gmake-4.2.zip
wine make.exe
---

but that still fails:

---
...
CreateProcess(Z:\bin\bash,/bin/bash -c "echo \"Building d_do_test tool\"",...)
Putting child 001DA438 (test_results/d_do_test.exe) PID 1578448 on the chain.

Live child 001DA438 (test_results/d_do_test.exe) PID 1578448 
make: *** WaitForMultipleObjects: No such file or directory.  Stop.

I assume this is due to missing bash. Did either of you manage to install bash?


Last but not least, there's also:

https://github.com/braddr/at-client/blob/master/src/do_test_dmd.sh

I see cygpath there. So I maybe cygwin is needed to run DMD's testsuite?
