A solution to Linckelmann's gluing problem in all fusion systems of blocks yields an alternative formulation of Alperin's weight conjecture. Using Bredon equivariant cohomology techniques we solve the gluing problem in fusion systems (of blocks) which are isomorphic to the fusion systems of the symmetric groups or the alternating groups or $GL_d(q)$ or $SL_d(q)$ at the defining characteristic.
