[users at bb.net] Question on passing state between steps

[Greg Bullock]

I faced a similar problem.  To work around it, I have a batch file (see 
below) to run consecutively all the steps that need to share the 
environment.

It's not perfect.  In particular, I've had trouble getting useful 
stdout/stderr logs and error code back to the builder when one of the 
steps fails.

I'd appreciate your sharing back any improvements you make on this.


echo off
setlocal

set THREAD_CFG=%~1
if /i "%~1"=="" set THREAD_CFG=single
set LIB_LINKING=%~2
if /i "%~2"=="" set LIB_LINKING=shared
set CMAKE_BUILD_TYPE=%~3
if /i "%~3"=="" set CMAKE_BUILD_TYPE=Release
set PROJ_FOLDER=%~4
if /i "%~4"=="" set PROJ_FOLDER=Main_Project

echo %path%

error. Disable for now.

endlocal
