Now we need to check how libippi had exported its symbols. :-) For example, to check the symbols from the libfoo.a sent in my previous message: $ objdump -t libfoo.a In archive libfoo.a: libfoo.o: file format pe-i386 SYMBOL TABLE: [ 0](sec -2)(fl 0x00)(ty 0)(scl 103) (nx 1) 0x00000000 foo.c File *[ 2](sec 1)(fl 0x00)(ty 20)(scl 2) (nx 1) 0x00000000 _bar* AUX tagndx 0 ttlsiz 0x0 lnnos 0 next 0 [ 4](sec 1)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .text AUX scnlen 0xa nreloc 1 nlnno 0 [ 6](sec 2)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .data AUX scnlen 0x0 nreloc 0 nlnno 0 [ 8](sec 3)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .bss AUX scnlen 0x0 nreloc 0 nlnno 0 [ 10](sec 4)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .rdata AUX scnlen 0x4 nreloc 0 nlnno 0 [ 12](sec 5)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .rdata$zzz AUX scnlen 0x2a nreloc 0 nlnno 0 [ 14](sec 6)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .eh_frame AUX scnlen 0x38 nreloc 1 nlnno 0 Notice the _bar, now you need to check if libippi exported it as ippithreshold_ltvalgtval_8u_c1ir, _ippithreshold_ltvalgtval_8u_c1ir or ipp__ippithreshold_ltval_8u_c1ir. :-) -- Silvio Clécio
