[snip] > ((FUNC)DLXGetEntry(myd1,"testproc"))(); /* GPF!!! */ Aside from any othe consideration, you should ALWAYS catch a function pointer like this in a variable and make sure it's not NULL. Either GetEntry isn't finding your function (maybe try "_testproc"), or there is some bug in DLX. > - and a second problem: "extended DLX" does not support C++: It probably does, but doesn't now it yet. The problem is most likely that the linker script it probably comes with doesn't yet mention the sections introduced by gcc 2.95. Something similar to this is required: ---- OUTPUT_FORMAT("coff-go32") FORCE_COMMON_ALLOCATION SECTIONS { .dlxdata : { *(.text) *(.gnu.linkonce.t*) *(.const*) *(.ro*) *(.gnu.linkonce.r*) etext = . ; _etext = .; dlx_first_ctor = . ; *(.ctor) dlx_last_ctor = . ; dlx_first_dtor = . ; *(.dtor) dlx_last_dtor = . ; *(.data) *(.gnu.linkonce.d*) ___EH_FRAME_BEGIN__ = . ; *(.eh_fram*) ___EH_FRAME_END__ = . ; LONG(0) *(.gcc_exc*) edata = . ; _edata = .; _object.2 = . ; . += 24 ; *(.bss) *(COMMON) end = . ; _end = .; } } ----- This is taken from my own patched DLX library, which includes exception support and compression.
