Undefined reference with Qt 4.8.6 and Intel icc

I upgraded to Qt 4.8.6 and compiled on Ubuntu 14.04 and Intel icc - this time I get undefined references . I do have libpng1.6.18 installed under /usr/local/lib and it is there on my LD_LIBRARY_PATH.

Any suggestions ?


cd src/gui/ && make -f Makefile

This is how I ran it - ./configure --platform=linux-icc-64 -system-libpng

and then typed make.

Look at the linker line in your compiler output.
Does it contain "-L /usr/local/lib"?

LD_LIBRARY_PATH is irrelevant here, it is input for the runtime linker "ld".

Success !
I got this to compile !

./configure --platform=linux-icc-64 -qt-libpng and it worked.
