// All XASH_* macros set by this header are guaranteed to have positive value otherwise not defined
/*
All XASH_* macros set by this header are guaranteed to have positive value
otherwise not defined.
// Any new define must be undefined at first
// You can generate #undef list below with this oneliner:
// $ cat build.h | sed 's/\t//g' | grep '^#define XASH' | awk '{ print $2 }' | sort | uniq | awk '{ print "#undef " $1 }'
//
// So in various buildscripts you can grep for ^#undef XASH and select only second word
// or in another oneliner:
// $ cat build.h | grep '^#undef XASH' | awk '{ print $2 }'
Every macro is intended to be the unified interface for buildsystems that lack
platform & CPU detection, and a neat quick way for checks in platform code
For Q_build* macros, refer to buildenums.h
Any new define must be undefined at first
You can generate #undef list below with this oneliner:
$ sed 's/\t//g' build.h | grep '^#define XASH' | awk '{ print $2 }' | \
sort | uniq | awk '{ print "#undef " $1 }'
Then you can use another oneliner to query all variables:
$ grep '^#undef XASH' build.h | awk '{ print $2 }'
