Hi,

whats wrong?

PS: same issue on ubuntu 14 :(
my project unclused also other libicu versions its a QT project, can that be the problem? on windows and max no problems

I found the issue, the v8 was linked against the system libicu and not the one it compiled itself, to solve the issue i needed to use
chrpath -r \$ORIGIN ./libv8.so

./Final/libv8.so: RUNPATH=$ORIGIN/lib.target/
./Final/libv8.so: new RUNPATH: $ORIGIN


for whatever reason the v8 lib is linked to expect the own libs in a sub dir that was missing and than it defaulted for the os libs
