Hi I have just moved from Red hat to Ubuntu. Having installed the gd library with: sudo apt-get install libgd-dev. I find that I get the following errors: Viewer.cpp: In function ‘void saveimage(int, int, const char*)’: Viewer.cpp:698: error: ‘gdImageCreateTrueColor’ was not declared in this scope Viewer.cpp:705: error: ‘gdTrueColor’ was not declared Any ideas how I can correct. Before in Redhat I was prob using an earlier version of gd. How can I make this up2date. Any help is appreciated. Rgrds
