[Tinyos-help] Can't Blink with "make micaz sim"

[Sivan Toledo]

Phil, I double checked that I only installed the cygwin packages, not 
the Linux one. Here is a list of the RPM's that I installed:


stoledo at swift /opt/tinyos-2.x/apps/Blink$ ls 
/cygdrive/c/temp/Cygwin-Downloads/TinyOS/

avarice-2.4-1.cygwin.i386.rpm
avr-binutils-2.15tinyos-3.cygwin.i386.rpm
avr-gcc-3.4.3-1.cygwin.i386.rpm
avr-insight-6.3-1.cygwin.i386.rpm
avr-libc-1.2.3-1.cygwin.i386.rpm
msp430tools-base-0.1-20050607.cygwin.i386.rpm
msp430tools-binutils-2.16-20050607.cygwin.i386.rpm
msp430tools-gcc-3.2.3-20050607.cygwin.i386.rpm
msp430tools-libc-20050308cvs-20050608.cygwin.i386.rpm
msp430tools-python-tools-1.0-1.cygwin.noarch.rpm
nesc-1.2.7b-1.cygwin.i386.rpm
tinyos-2.0.0beta2-3.cygwin.noarch.rpm
tinyos-tools-1.2.2-1.cygwin.i386.rpm


Trying the command "OSTYPE=cygwin make micaz sim" did make things a 
little better. (It seems that OSTYPE is not set at all on my machine for 
some reason; when I printenv OSTYPE I get nothing back. It is a pure 
TinyOS cygwin that I installed from the tar.gz on the TinyOS web site, 
not from cygwin.com.)


stoledo at swift /opt/tinyos-2.x/apps/Blink
$ OSTYPE=cygwin make micaz sim
mkdir -p build/micaz
  placing object files in build/micaz
  writing XML schema to app.xml
  compiling BlinkAppC to object file sim.o
ncc -c -DUSE_DL_IMPORT -fpic -o build/micaz/sim.o -g -O0 -tossim 
-fnesc-nido-tos...

...

g++ -fpic -W1,--enabled-auto-image-base   build/micaz/pytossim.o 
build/micaz/sim
.o build/micaz/tossim.o -L//usr/include/python2.3/config -lstdc++ 
-lpython2.3 -o
 _TOSSIM.dll
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/../../../../i686-pc-cygwin/bin/ld: 
cannot
find -lpython2.3
collect2: ld returned 1 exit status
make: *** [sim-exe] Error 1


So it's failing to find the python library. I think that it is indeed 
not installed and that it was not included in the cygwin installation on 
the TinyOS web site. Here is the output of the commands that search for 
this library (it's not on my system) and that enumerate the 
python-related cygwin packages; it only includes the python base 
package. So perhaps something like python-devel or something similar is 
missing from the installation. I'll try to find a compatible python 
developement package.


Thanks a lot. Sivan
