Hello all,

Has anybody managed to build this "demo package" from "J.C. Wren" in
windows with cygwin/gnuarm ?
I'm getting a lot of errors... All files compile OK (with some minor
warnings), but the linking won't work. I think it's because of
cygwin's handling of windows directories... I.E., "G:\LPC2148_Demo" is
translated by cygwin by "/cygdrive/g/LPC2148_Demo", as you can see in
the "pwd" command answer below:
"
G:\LPC2148_Demo>pwd
/cygdrive/g/LPC2148_Demo
"

I've modified the root Makefile in the "ROOT" environment variable
from "export ROOT=$(shell pwd)" to "export ROOT=G:/LPC2148_Demo" and
all files compile OK, but in the linking I get *a lot* of errors,
because (i guess) of the "common.a" file that has references to the
"/cygdrive/g/LPC2148_Demo" notation instead of "G:\LPC2148_Demo" used
by windows.

So, has someone successfully built this package under
windows/gnuarm/cygwin ?

Best regards,
Carlos Santos.

No problem, your LPC2148 demo is awesome, please go ahead. I have
referred to it extensively in building my latest project, which I hope
to unveil soon.

Ah, cool. I'll have to load up the Winders version of the tool chain
and try it out. The newlib I use is the one that the Gentoo
'crossdev' tool selects.

Thanks,

One more thing.... your demo requires the version of newlib without
the syscall stubs and without reentrant syscalls. WinARM and most
distributions don't have this. I compiled a newlib with this. It
should be in the distribution of

minibasic-arm-0.5e.zip

in the LPC2000 Group files section. There is a libc.a, libm.a, and
libg.a in there that should work with the LPC 2148 demo. I had to
include "-nostartfiles" in the linker line so it would use my stripped
down newlib rather than the full version. You can distribute this
library with your code if you wish (it's just a customized newlib).

Dan, if you don't mind, I'd like to include your Makefile in my next
release. I've made a handful of changes to the codebase for another
project, and have plans in the next couple weeks to backport them into
the demo code.

Hello,



Dan, I used your makefile with the following modifications:

export ROOT=G:/LPC2148_Demo # <-- this is the dir where I have my files



and exchanged

$(CC) $(CFLAGS) $(ARM_OBJ) -nostartfiles $(CRT0) $(LINKER_FLAGS) -nostdlib
lib/libc.a lib/libgcc.a

by

$(CC) $(CFLAGS) $(ARM_OBJ) -nostartfiles $(CRT0)
$(LINKER_FLAGS)

(like in the original Makefile that came with the examples)



Im getting the same kind of links like before, after compiling all the
files. The problem is in the linking phase. Heres some of the errors I get:



arm-elf-gcc -Wall -Wextra -Wshadow -Wpointer-arith -Wbad-function-cast
-Wcast-align -Wsign-compare -Waggregate-return -Wstrict-prototypes
-Wmissing-prototypes -Wmissing-declarations -Wunused -D
RUN_MODE=RUN_FROM_ROM -D GCC_ARM7 -IG:/LPC2148_Demo
-IG:/LPC2148_Demo/FreeRTOS/include -mcpu=arm7tdmi -Tlpc2148-rom.ld -g -O3
-fomit-frame-pointer -D CFG_CONSOLE_UART0 main.o -nostartfiles boot.s
G:/LPC2148_Demo/common/common.a -Xlinker -olpc2148.elf -Xlinker -M -Xlinker
-Map=lpc2148.map

G:/LPC2148_Demo/common/common.a(tasks.o): In function
`ulTaskEndTrace':/cygdrive/g/LPC2148_Demo/FreeRTOS/tasks.c:1311: undefined
reference to `vPortEnterCritical'

/cygdrive/g/LPC2148_Demo/FreeRTOS/tasks.c:1313: undefined reference to
`vPortExitCritical'

`vTaskStartTrace':/cygdrive/g/LPC2148_Demo/FreeRTOS/tasks.c:1292: undefined
reference to `vPortEnterCritical'



Im almost getting to the point of compiling this in linux, but I have to
install and setup the arm toolchain and didnt want to go trough this

Can someone give advice here?



Regards,

Carlos.

Ah, cool. I'll have to load up the Winders version of the tool chain
and try it out. The newlib I use is the one that the Gentoo
'crossdev' tool selects.

Thanks,

Hello again,



Nevermind the questions about makefiles It was a problem with the windoze
PATH environment variable It was because of the openocd entry in the PATH
E.V. (conflicts between cygwin and openocd sh.exe inside the C:\Program
Files\openocd-r423\utils\bin directory). Just removed the 2 entries of the
openocd in the PATH and everything compiled at the first time



Sorry for the previous posts about this ;)



Regards,

Carlos.

Don't apologize. In the next release, I'll be sure to mention that
for you folks that have to suffer working in a Windoze environment.
