Weird. There seems to be different version of the .h files running around not sure the exact problem here. Only reference I can find to this value is in float.h under /usr/include/gcc/darwin/3.3 I did use gcc 4.0 not 3.3 so not sure of the 3.3 behavior But looking at the floats.h it will not parse without the symbol present.
… But lets focus on a simple solution. For symbols that are hard defined in a compiler ( GCC) You can just transfer them to the interrogate preprocessor. Something like this .
- From the command line
gcc -E -dM - < /dev/null | grep “__FLT_EVAL”
#define FLT_EVAL_METHOD 0
- Then we need to let interrogate know what the compiler thinks this symbol. A simple answer is to modify the SYSTEM_IGATE_FLAGS in Config.osx.
#define SYSTEM_IGATE_FLAGS -D__ppc__ -D__const=const -Dvolatile -D__BIG_ENDIAN__ -D__inline__=inline -D__GNUC__ -D FLT_EVAL_METHOD=0
Again I am curious what compiler version you are using
Seeing a “cpp –v “ would be great … Here is mine.
cpp -v
