On Tue, 6 Mar 2012 09:26:56 +0100 [email protected] said: i do not know what is wrong. this should work. the symbol seems exported. it should work. it works everywhere else i see on x86, x86-64 and arm. dlsym() is simply reporting that the symbol doesnt exist - maybe there is a ld.so limit on number of shared libs able to be opened or something on mips? i really don't know - i'm stretching here. but your core problem is the software_generic module that all the software rendering modules depend on and load in addition is missing a symbol necessary for it to function, even though nm reports its there.
