ECST does not compile (gcc or clang) on Windows, issue is either with boost::hana or ECST itself. about ecst HOT 8 CLOSED

Ah okay, well it seems from this #29 that it will be easiest to just use a g++ or clang compiler instead - I may try Visual Studio with g++ or clang dropped in as the compiler, I'll report back with results.

from ecst.

@anonanon17: this is an ecst bug, not related to Windows. I will fix it ASAP.

from ecst.

I'm so confused, every other header-only library I have used is just a .dll, a .lib and a bunch of header files.

Well first of all if a library is 'header-only' then it, by definition, would not have any .dll/.lib/.a/whatever other files, only *.h/*.hpp. ^.^

Same with this library, you only need to include the include directories and 'use' them in your project.

I've not tried it in VC (I'm a linux user myself) but I'd imagine the parts of the source that do not work are probably just some GCC intrinsics or some #ifdef's or something that you could fix yourself and PR the fixes back here. :-)

You'd start by just making your project in VC, then just linking in the headers from this project, then find what does not compile as you try to use it and fix it (and PR the fixes back), and repeat. :-)

from ecst.

Update:

Visual Studio g++ was incredibly unfriendly so I've switched to Code::Blocks using MinGW gcc as the compiler.

Unfortunately, after linking boost, ecst, vrm_core and vrm_pp I get some errors in the ecst code that I believe may be actual errors and not just linking issues. Do you have any ideas?

EDIT: I believe this is an issue with my MinGW installation - I think I have the Win32 threads rather than Posix threads, I will report back when I try Posix shortly.

EDIT 2: Made sure I'm using Posix, but still get the same errors. I'm very confused at the moment.

EDIT 3: Turns out the "standard" MinGW installation does not support Posix (or if it does, not easily). I installed MinGW-w64 and got a little bit further, see the below post.

Update 2:

Uninstalled MinGW, and installed MinGW-w64 (which supports Posix properly). I now get the following errors:

EDIT: I have looked through every single issue, and the only hope seems to be using nuwen MinGW #15, although this is just a package containing the latest boost and MinGW-w64 so I can't see why this would make a difference. I will update when I have tried again.

EDIT 2: So I uninstalled MinGW-w64 and installed nuwen MinGW. I get exactly the same errors upon building, which makes me believe this is an error with ECST itself as the creator mentions using nuwen MinGW to successfully build ECST in #15 .

At this point I believe it is probably best for me to abandon hope of using ECST and roll my own solution. If anyone does have a solution to the compilation issues I'm facing that would be great.

EDIT 3: In case anyone is reading this in the future, these are the steps I took that did not work:

1 - Clone ECST repo.
2 - Run setup .sh script.
3 - Install Code::Blocks and nuwen MinGW using this tutorial: https://solarianprogrammer.com/2017/11/22/install-codeblocks-gcc-windows/
4 - Check the gcc compiler is working fine (it was).
5 - Create a new console project.
6 - Insert the "code sample" code from the repo.
7 - Link the ecst, vrm_core, vrm_pp and boost libraries.
8 - Build.

I get exactly the same errors (below) that I got with any other MinGW installation. I can only conclude there is an issue with ECST, or some magic trick that will get it working. Either way, I unfortunately do not have time to mess around with this any longer.

@anonanon17 : Let me know if 30cfe09 fixed your build issue.

BTW, if you need a Windows implementation of std::thread, check out:
https://github.com/meganz/mingw-std-threads

from ecst.

Appears to have fixed the issue, thanks! I used gcc to compile (via nuwen MinGW) and I will try a clang build later.

I'm going to go through making a basic setup using your thesis as a guide, and I'll let you know if I encounter any problems. I'm fairly certain the original issue is fixed.

Will also check out that std::thread implementation, thanks.
