hi Oberbrunner

windows7  32bit
scons 2.2.0

I guest I should add the following code in my SConsruct

if rtconfig.PLATFORM == 'armcc':
    env["TEMPFILE"] = SCons.Platform.TempFileMunge
    env["LINKCOM"] = "$LINK -o $TARGET $LINKFLAGS --via
${TEMPFILE('$SOURCES')}"
    env["TEMPFILEPREFIX"] = '  '      # arm tool chain


Then I recompile with scons -j4  in CMD

armlink -o rtthread-stm32.axf --device DARMSTM --info sizes --info totals
--info
 unused --info veneers --list rtthread-stm32.map --scatter stm32_rom.sct
--libpa
th D:/Keil/ARM/RV31/LIB --keep __fsym_* --keep __vsym_* --via
build\application.
o @c:\users\admini~1\appdata\local\temp\tmp5r9pd_.lnk
Using tempfile c:\users\admini~1\appdata\local\temp\tmpojzbmz.lnk for
command li
ne:
build\application.o build\startup.o build\board.o build\stm32f10x_it.o
build\rtc
.o build\usart.o build\serial.o build\led.o build\enc28j60.o
build\dm9000a.o bui
ld\touch.o build\calibration.o build\ssd1289.o build\src\clock.o
build\src\device
......

seems there two places are wrong.
the command line should be
1.  there should not be an @ at the head of the tempfile's path,
while env["TEMPFILEPREFIX"] = '   ' doesn't help.
2.  there is an ‘build\application.o’ behind “--via”  in the command line,
but it is already in the tempfile, and should not be there

the Right command should be：
armlink -o rtthread-stm32.axf  $LINKFLAGS --via
c:\users\admini~1\appdata\local\temp\tmp5r9pd_.lnk

Any suggestions?

Best Regards
prife
