Thank you allf or the support. For some reason the above library did not compile on my mechine due to some undeclared variables. Not sure how it is working for others. After I corrected those, it compiled and worked without any issue. I will add the lines that I had to add to the library to get compiled. Also had to delete one more file from the library that Intel galileo is not using. For some reason, compiler try to read that al though that file is not called in any where in the code. I used a normal arduino board to communicate with LCD and that board was connected to Galileo using serial port. Since galileo can now run LCD directly, no more regular arduino boards are used in my project.
Thank you,
