runscons.bat - Run SCons, collecting and filtering warnings

First, run the build, collecting all errors and warnings into err.txt.

call scons -j 1 %* > err.txt 2>&1
 

Remove #warnings generated during compiles

Note: the > errn.txt was placed immediately after findstr below, since the use of \" confuses cmd.exe (but not findstr). Placing it at the end prevents cmd.exe from capturing output to the errn.txt file.

Therefore, I can’t use the ^ line continuation character following lines where the " symbols don’t match.

findstr > err1.txt /V ^

Work around compiler warnings I can’t figure out how to suppress

findstr > err3.txt /V ^
/C:"\bootloader\pic24_dspic33_bootloader.X\mem.c:119:1: warning: control reaches end of non-void function" ^
/C:"warning: Taking the address of '" ^
err2.txt
 

Output only errors and warnings

findstr /C:"warning" /C:"error" err3.txt > build_errors.txt
echo Errors and warnings:
type build_errors.txt
