Error using rez on windows

I’m trying to build the hello_world example package provided with rez but I’m getting errors just doing the cmake compiler tests that I don’t get when just running cmake by itself without rez.

When I run rez-build on the hello_world project, I get the following output:

NOTE: I get this same output even if the CMakeLists.txt file only contains the cmake_minimum_required command

rez: BuildError: The cmake build system failed

However, if I just use cmake directly to build the hello_world project, I get this successful output from cmake

NOTE: obviously, I have to remove everything except the cmake_minimum_required command from the build file, but the C compiler tests complete succesfully using cmake and not with rez.

Hey Guys!

This isn’t the most ideal solution yet (running vcvarsall.bat is very slow), but it does fit into rez’s workflow, and cmake works as expected. If this is all fairly obvious, I’m sorry. I am new to both rez and software compilation on windows.

1) Get a Compiler

You can’t compile without a compiler. Firstly, make sure you actually have one. You can install cmake and the microsoft build tools most easily using chocolatey).

choco install -y cmake
choco install -y visualstudio2017buildtools
choco install -y visualstudio2017-workload-vctools

2) Create a vscode Rez Package

Add a package for vscode right in your rez package repository. This package will call vcvarsall.bat and set up your cmd.exe’s environment variables

# directory structure:

$env:USERPROFILE\packages\
    vscode\
        x64_2017_14.13.2612\
            package.py

...\vscode\x64_2017_14.13.2512\package.py

uuid = 'b9be08860d4e4f32bb5c861fce92f268'
name = 'vscode'
version = 'x64_2017_14.13.2612'

def commands():
    vcvarsall = 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Auxiliary\\Build\\vcvarsall.bat'
    command( '"{}" x64'.format(vcvarsall) )

3) Create a 2nd Rez Package (one to compile with cmake)

We’ll build this package normally using rez-build. Create it somewhere other than your rez package repository.

2nd Package Structure

package/
    emptyfile.txt         # just something arbitrary to package
    CMakeLists.txt
    package.py

CMakeLists.txt

cmake_minimum_required(VERSION 3.0)

include(RezBuild)

rez_install_files(
    emptyfile.txt
    DESTINATION .
)

package.py

import sys
uuid = '...' # some uuid
name = 'cmaketest'
version = '0.0.a1'

build_requires = []
if sys.platform == 'win32':
    build_requires.append('vscode')

4) rez-build

Now you can run rez-build, and both cmake and NMake’s will run vcvarsall.bat , so your path and the myriad of other computer-specific variables required to compile in windows.

cd $your_package
rez-build

Just a note - build_command is preferrable to bez, as I would like to deprecate bez.

<snip from google group>

I would like to deprecate bez in favor of custom build commands ( https://github.com/nerdvegas/rez/wiki/Building-Packages# custom-build-commands). Fortunately it is trivial to convert a rezbuild.py to a custom build command, like so:

 # in package.py
 build_command = "python {root}/rezbuild.py {install}"

# add this to rezbuild.py
if __name__ == '__main__':
    build(source_path=os.environ['REZ_BUILD_SOURCE_PATH'],
        build_path=os.environ['REZ_BUILD_PATH'],
        install_path=os.environ['REZ_BUILD_INSTALL_PATH'],
        targets=sys.argv[1:])

Thx A
