Accepts escape sequence in path

[etcimon]

On windows, when running with the command: ./android-setup.exe C:\Users\PC\AppData\Local\Android\Sdk

This is copied to the ldc2.conf file as-is and I get errors when building:

line 54: Unexpected escape sequence: \U

[adamdruppe]

oh i probably need to .replace(\, \\) don't it.....

would you mind hand-editing the file and seeing if doubling the backslashes works?

[etcimon]

The forward slash works, I noticed it also takes the path of the libs-dirs with native slash lib-dirs = [ "A:\development\d_android/runtime_droid_x86", ];

[adamdruppe]

ok i'll just replace it all with forward slashes then....

Everything being fixed, this is where it fails for me:

I think it should be calling clang++.exe on Windows according to the cmd. files under the same path

[adamdruppe]

hmmm looks like it is ERROR_BAD_EXE_FORMAT.

does it need .exe added to the end of the config?

(tbh I did most my testing on linux since android studio kept crashing on me on windows. super surprising, usually i find stuff just works on windows and fails on linux!)

[adamdruppe]

what's the full path of your thing that runs successfully?

[etcimon]

The full path would have to be C:/Users/PC/AppData/Local/Android/Sdk/ndk/21.0.6113669/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++ --target=armv7a-linux-androideabi21 but I don't know how to pass that as an -gcc= switch

argh I'll have to come back to this, I'm out of time tonight.

thanks for working with me on it though, i'm sure it is something simple here but i gotta work it again.

[etcimon]

There should be some kind of -CFLAGS= argument so that -gcc can stay the path of an executable and so that I can set --target=... for it

[adamdruppe]

it might help to just put that ++ at the end of the -gcc=.......clang line. the docs imply that is all it needs there. just on my install both things do the same thing

But the idea of this config is that it is specialized on target already. (my original version of this broke it all out separately but the ldc team told me tis config is supposed to work more generically)

[etcimon]

Using clang++.exe without a flag, I also needed to use
"-linker=C:/Users/PC/AppData/Local/Android/Sdk/ndk/21.0.6113669/toolchains/llvm/prebuilt/windows-x86_64/bin/arm-linux-androideabi-ld.exe",`

and then I'm stuck on:

[adamdruppe]

the -gcc option is supposed to give it a root path to find all that stuff

sorry i really do need to get to bed, but here's the doc page i was trying to follow:
https://developer.android.com/ndk/guides/other_build_systems

[adamdruppe]

Error: module d_android.hacks from file ....\AppData\Local\dub\packages\d_android-0.0.5\d_android\source\hacks.d is specified twice on the command line

annoying. but after fixing that, otherwise clean system, i am indeed able to reproduce your error.

Simply adding ".cmd" to the end of the -gcc line in the config file got it past this.

Pushed a new commit to fix the problems in android-setup.d. You'll need to grab that rebuild, delete the config it made in ldc2.conf and delete the runtime-* directories so it starts fresh. but now it works. just need to figure out why it thinks hacks is specified twice then i can tag a new version
