Now i just stumbled over the target libc's long double being 64bit only. My question now is: is there some easy way of forcing gcc to use 64 for long double, just like for double? it may well be a hack as the patch is quite specific for now anyway. >> >> i tried to #define LONG_DOUBLE_TYPE_SIZE 64, but after some inspection of the code, i realized that this wont work. is there some magic location where i could just tell gcc to handle long double like double? any help would be much appreciated! >> >> regards, markus > Is there an error in your post? You're saying that a long double is "64bit only," and you wish to force "gcc to use 64 for long double." No. What i meant was that the system libc seems to think that long double is 64bit (as it was compiled with a different compiler), and gcc uses sth different (80/96 bit). i want to force gcc to use 64 bit to be compatible with my libc.
