hello, I have been trying to build on windows 11 and I am using VIsual Studio 2017, LLVM10 and Cmake 3.17.1. I am getting the following error.

Could you please provide the entire log, starting from the command you've ran, as well as the output of bash -c "which make" and bash -c "make --version" ?

[mufaawan]

Commands results.

C:\Users\usman\Documents\Umar\Sighthound\SighthoundVideo>bash -c "which make"
/mingw64/bin/make

and

The log is too long to match the allowed character lenght of github comment. I have attached a text file. Command-prompt-log.txt

Here's list of all environment variables.

[mufaawan]

I am using the make from msys2 as per instructions in this comment. https://github.com/sighthoundinc/SighthoundVideo/issues/3#issuecomment-1507486157

[w3sip]

Okay, I've attempted to reproduce -- but no luck, seems to build. This is the script I've used:

set PATH=u:\cmake-3.17.1\bin;u:\git\bin;u:\git\usr\bin;%PATH%;u:\llvm10\bin;u:\make
echo "=============================="
bash -c "which make"
echo "=============================="
bash -c "make --version"
echo "=============================="
ninja --version
echo "=============================="
set
bash buildSV.sh

Your make version seems to be correct (and matching mine)

[w3sip]

This is the output I'm seeing:

u:\code\SighthoundVideo>echo "=============================="
"=============================="

Just to confirm -- you're running from the MSVC command prompt (i.e. this):

[w3sip]

One thing that I see -- you have .\Git\mingw64\bin on PATH. That has a chance of introducing mingw toolchain utilities into the mix (with the outcome being a mixup not unlike the one you're seeing).

I am using the mentioned cmd prompt.

My ninja version is 1.11.1

Also my bash -c "make --version" shows exact output as yours.

[mufaawan]

One thing that I see -- you have .\Git\mingw64\bin on PATH. That has a chance of introducing mingw toolchain utilities into the mix (with the outcome being a mixup not unlike the one you're seeing).

What solution do you recommend here? I have collected make.exe and placed in my ./git/mingw64/bin as per instrctions here.

[w3sip]

This mirrors my setup here -- except I don't have anything mingw64-related on PATH. Git bash seems to be able to locate make without added entries, and having mingw compiler toolchain on PATH seems to interfere with CMake/MSVC ability to build.

[mufaawan]

Seems like the C:/Program Files(x86)/Inno Setup 5 has been hard coded somewhere?

[w3sip]

You're correct

Seems like the C:/Program Files(x86) Inno Setup 5 has been hard coded somewhere?

You're correct: here it is - https://github.com/sighthoundinc/SighthoundVideo/blob/main/frontEnd/WinInstaller.py#L500

[w3sip]

I will create PR. Are you accepting PRs by any chance?

While it will not be merged immediately, since published version of SV is a derivative of a closed source SV, with some things like cloud connectivity (bug reporting, licensing, etc) and proprietary models being stripped out, we will definitely accept code contributions and integrate them for future updates after vetting.

[mufaawan]

Thank you so much. I will make a proper guide with right link to resources and create a PR. I am closing the issue.

PS: Sorry for a deleted comment mentioning the PR of updated readme.md.

[mufaawan]

Issue resolved.

[mufaawan]

@w3sip log says the installer file has been generated. But I couldn't find the file on path. C:\Users\usman\AppData\Local\Temp\.build-obs\installer-out\frontEnd-Win\Sighthound Video Setup.exe

Does it has to do something with signing with Inno?

[w3sip]

No, signing is optional. I'll need to see why, but the installer ends up in ./build/installer-out/frontEnd-Win/:

u:\code\SighthoundVideo>dir .\build\installer-out\frontEnd-Win
 Volume in drive U is WORK_M2
 Volume Serial Number is 889D-1D0A

               2 Dir(s)  30,003,245,056 bytes free

[mufaawan]

Ok, I can see it inside the root directory of the project. I thought path for installer is inside AppData/Local/Temp/.build-obs like mentioned in printed messages in the screenshot.

[w3sip]

Yes, definitely inconsistent -- will investigate.

[w3sip]

@mufaawan - looks like it's being moved after creation. Probably to make it more accessible than a temp build folder, but yes, a bit confusing: https://github.com/sighthoundinc/SighthoundVideo/blob/main/frontEnd/FrontEnd.mk#L256

[mufaawan]

@w3sip how would I execute the project to test during development? I mean what's the start command? I want to make some changes and test the project during change implementation.

[w3sip]

@mufaawan - Try working with this: https://github.com/sighthoundinc/SighthoundVideo/blob/main/app
