issue during make (mingw32-make)

[CoffeeIsLife87]

link removed IDK what to do here

[thaytan]

Your log file isn't public. It'd be better to attach it directly here.

[CoffeeIsLife87]

errors.txt sorry about that

[thaytan]

You should be able to change the #if defined(WIN32) on the line above to #if defined(_MSC_VER) - the vsnprintf() variant should work on mingw32

[CoffeeIsLife87]

Now there are m_pWatchdogThread errors errors.txt

[thaytan]

I'm not sure what's going on there. AFAICS, the include is already there at line 9. https://sourceforge.net/p/mingw-w64/discussion/723797/thread/67f35b9c/?limit=25 suggests that MingW might require an extra clause in the CMakeLists:

-std=gnu++11 compiler flag may also need to added in CMakeLists.txt like

[CoffeeIsLife87]

where in cmakelists.txt would I put that?

[thaytan]

Try like this, near the existing MSVC check:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index b176519..29e779f 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt

+if( MINGW )

same issue :( errors.txt would it help to see all the mingw tools I have installed?

[CoffeeIsLife87]

The following zip has a package list as well as a python tool for searching through it (it is REALLY long) packages.zip

[thaytan]

I'm a bit out of ideas at that point. I read something about there being 2 different threading models available to choose in MingW (win32 vs posix) that might make a difference, but I don't really know.

[CoffeeIsLife87]

yeah I saw that somewhere too and I did try posix but it also didn't work. :( I am guessing you are on linux so you don't have to deal with this kinda stuff? do you think cygwin would work?

[thaytan]

I'm on Linux, yes. Although if I was going to try compiling on Windows these days, I'd first try the Meson build with MSVC before MingW

[CoffeeIsLife87]

I tried meson and ninja first unfortunately ninja also spits out m_pwatchdogthread errors I don't have enough uses for visual studio to install it for one project VScode works fine for what I do (I work in python on small tools that I use)

[thaytan]

I understand. For Windows at least, it would be great if we could provide releases here - but this project isn't quite advanced enough for that yet

[CoffeeIsLife87]

I tried use msvc 2019 after running meson --backend vs and here is the log after using "msbuild steamvr-openhmd.sln" errors.txt

[ChristophHaag]

About mingw: I don't know windows well but there is a possibility that SteamVR can't even load plugins built with mingw. As Valve's OpenVR driver header clearly doesn't support building with mingw, I would too recommend to try with msvc first.

CMake also has generators for various msvc/visual studio versions: https://cmake.org/cmake/help/v3.14/manual/cmake-generators.7.html#visual-studio-generators but they won't help with the errors you're seeing now.

driver_openhmd.cpp(51,13): error C2131: expression did not evaluate to a constant

I remember reading that msvc does not support variable length arrays. Changing this in the code should be pretty simple.

driver_openhmd.cpp(555,48): error C2065: 'M_PI': undeclared identifier

yea I guess M_PI is not in a C standard. Easy fix should be

#ifndef M_PI
#define M_PI (3.14159265358979323846)
#endif

driver_openhmd.cpp(649,22): error C2513: 'float': no variable declared before '='

really, msvc? https://stackoverflow.com/questions/118774/is-there-a-clean-way-to-prevent-windows-h-from-creating-a-near-far-macro

driver_openhmd.cpp(665,1): error C2059: syntax error: ','

DriverLog() may be a different function prototype on windows?

[TheOnlyJoey]

Actually, i think other then having to add the M_PI line, i got this compiled with meson and the provided build-win64.txt without any issues on linux.... So don't really know. I did have to do the near/far macro thing (i think i just undef'ed it). Worked fine on a Windows 10 setup.

[CoffeeIsLife87]

how do I use build-win64.txt meson ./configure? can I set it in cmake-gui?

[TheOnlyJoey]

Meson is a different build system from cmake. I only used it to build Windows binaries from Linux (https://mesonbuild.com/Cross-compilation.html)

[CoffeeIsLife87]

I fixed the most of the stuff using what you suggested except for the "expression did not evaluate to a constant" error errors.txt

[CoffeeIsLife87]

I download mingw-w64 and specified the 64bit compilers (they have posix I think) and it built fine but when I tried to install it says it can't find "openhmd.pc"
