Hi, We ran across an issue with qt-4.7 built with gcc-4.4 on AIX 5.2, 5.3, 6.1, and 7.1 where some static constructors were not being called. It turned out to be a header file issue, see, for example, https://www.ibm.com/developerworks/forums/thread.jspa?threadID=211873&tstart=-2 Using fixincludes to fix the header allows us to build a working qt. The erroneous struct declaration is: struct fc_softc { struct arpcom fc_ac; /* FCS common part */ struct ndd *nddp; /* returned from NS */ int(*efcnet_arp_fct) (struct ndd *, struct mbuf *); /* efcnet_arp function address */ } *fc_softc ; when fixed it becomes: typedef struct _fc_softc { struct arpcom fc_ac; /* FCS common part */ struct ndd *nddp; /* returned from NS */ int(*efcnet_arp_fct) (struct ndd *, struct mbuf *); /* efcnet_arp function address */ } *fc_softc ; David, do you have any idea if this is what it's supposed to be? Ok for trunk? Peter -- Peter O'Gorman pogma@thewrittenword.com
