Built on Mac OS X, throws internal error #22

cire831 commented 10 years ago

I'm building 1.3.5 on Mac OS X (10.7.5 Lion with Xcode 4.6.3), resultant image throws nesc: internal error.

help.

What app are you trying to compile?

I just tried to install nesc and tinyos tools on mac and eventually got it to work, but the process has some bumps that I need to sort out.

pretty sure, I was trying to build Blink.

can you send me directly, the steps you used to get it to work?

I'm on OS X 10.9.

I tried again by doing this:

Compiling nesc with clang didn't work, so I had to force it to use gcc. The gcc I have on my system is gcc-mp-4.7 from mac ports. My recent pull request to nesc makes setting CC in the configure step propogate through to nescc.

git clone git@github.com:tinyos/nesc
cd nesc
./Bootstrap
./configure CC=gcc-mp-4.7
make
sudo make install

Then I compiled the tinyos tools. I did this both on master and make-no-environ (both seemed to work).

cd git/tinyos-main/tools
./Bootstrap
./configure
make
sudo make install

Then I had to install the msp430 compiler.

sudo port install msp430-gcc
sudo port install msp430-libc

At that point compiling blip worked:

cd tinyos-main/apps/blink
make epic

Mac OS X now requires 16-byte alignment for allocated objects. Updated nesC's (internal) allocator to account for that.

Looks like there's an unrelated problem with nescc-mig and clang, though, looking into that.
