There are actually two problems with gcc-4.4. One is a missing #include which is easily fixed. The other problem is probably caused by the implicit -Wl,--as-needed (and thus perhaps also appears already with gcc-4.3, if all corresponding libraries had been recompiled): There is a -lGLU missing. I am not sure whether it is actually qt-gui which should be fixed or whether just the make system of freemat uses qt-gui falsely. Anyway, the attached patch solves both problems (the second by adding -lGLU to LIBS), and so freemat compiles (and links!) after the patch with gcc-4.4.

Martin, do you have edit rights for bugzilla? If so feel free to assign your gcc-4.4 related bugs if you are sure were they should go. Make sure to block bug 249226. If not, either comment here or come to #gentoo-bugs on freenode. I guess we could arrange this.
(In reply to comment #2) > Martin, do you have edit rights for bugzilla? Yes, but now I am almost through with my emerge -e world anyway...
Fixed, thanks.
