[gobolinux-users] CreateRootlessEnvironment currently broken for the macs

[Erick Tryzelaar]

Hello,

I wanted to play around with gobo on my mac, and it's currently not 
running. It looks like the build of "RescueSymlinkProgram" is trying to 
statically link the executable, which isn't really supported on macs:

rm -rf Resources/FileHash*
find * -path "*~" -or -path "*/.\#*" -or -path "*.bak" | xargs rm -f
cd src && make clean
cd ../bin; rm -f SuperUserName IsExecutable usleep LinkOrExpandAll List 
RescueSymlinkProgram
cd lib/python2.3/site-packages && rm -f *.pyc *.pyo
for f in FindPackage GetAvailable GuessLatest CheckDependencies 
DescribeProgram; \
do libf=lib/python2.3/site-packages/$f.py; \
   rm -f $libf; ln -nfs ../../../bin/$f $libf; \
done
cd lib/python2.3/site-packages && \
for f in *.py; \
do python -c "import `basename $f .py`"; \
done
sed -i~ "s/CURRENT_SCRIPTS_VERSION=.*#/CURRENT_SCRIPTS_VERSION="2.5.6" 
#/g" bin/CreateRootlessEnvironment
rm -f bin/CreateRootlessEnvironment~
cd src; make all

Here's apple's explanation: http://developer.apple.com/qa/qa2001/qa1118.html

Anyway, it looks like this was added in this patch to 
tools/Scripts/src/Makefile in version 1.13:

http://cvs.savannah.nongnu.org/viewcvs/tools/Scripts/src/Makefile?root=goboscripts&r1=1.12&r2=1.13

Would it be possible to check if the OS is apple before trying to 
statically link the executable?
