Hello everybody,
Running into a strange issue trying to compile SDCC with the msys2
environment.
I've successfully downloaded gputils from source and compiled:
$ gcc -v
<snip>
gcc version 6.3.0 (Rev2, Built by MSYS2 project)
$ gpasm -v
gpasm-1.5.0 #1285
(Apr 28 2017)
I configured SDCC using the following command line
./configure --disable-mcs51-port --disable-z80-port --disable-z180-port
--disable-r2k-port --disable-r3ka-port --disable-gbz80-port
--disable-tlcs90-port --disable-ds390-port --disable-ds400-port
--disable-hc08-port --disable-s08-port --disable-ucsim
(essentially, enable stm8 and PIC but nothing else)
STM8 and pic14 seem to build without errors, but it looks like something in
the pic16 lib is invoking gpasm incorrectly, as all of the 18f* file
command lines result in the usage information for gpasm being printed and
the build consequently fails with missing object files.
The error lines all have the following format:
source='fake_sspbuf.c' object='libdev18f1220_a-fake_sspbuf.o' libtool=no \
DEPDIR=.deps depmode=none /bin/sh ../depcomp \
'/c/source/sdcc/device/non-free/lib/pic16//../../../../bin/sdcc'
-DHAVE_CONFIG_H -I. -I.. -I. -I../../../../include/pic16
-I../../../../non-free/include/pic16 -p18f1220 --std-c99
--asm="'/mingw64/bin/gpasm'" --no-warn-non-free --fomit-frame-pointer
--obanksel=9 --denable-peeps --optimize-cmp --optimize-df --i-code-in-asm
-DUSE_FLOATS=0 -mpic16 -p18f452 -c -o libdev18f1220_a-fake_sspbuf.o `test
-f 'fake_sspbuf.c' || echo './'`fake_sspbuf.c
Usage: gpasm [options] file
Options: [defaults in brackets after descriptions]
-a FMT, --hex-format FMT Select hex file format. [inhx32]
-c, --object Output relocatable object.
<gpasm usage info follows>
Build fails much later with error:
error: "libdev18f1220_a-pic18f1220.o" is not a valid object file
Does anybody have any suggestions for how I can diagnose this?
Thanks,
Stephen
