8// Compiler/library version workaround macro
9//
10// Usage:
11//
Jeff Thompson3d613fd2013-10-15 15:39:04 -070012// #if NDNBOOST_WORKAROUND(NDNBOOST_MSVC, < 1300)
Jeff Thompsonf7d49942013-08-01 16:47:40 -070013// // workaround for eVC4 and VC6
14// ... // workaround code here
15// #endif
16//
Jeff Thompson3d613fd2013-10-15 15:39:04 -070017// When NDNBOOST_STRICT_CONFIG is defined, expands to 0. Otherwise, the
Jeff Thompsonf7d49942013-08-01 16:47:40 -070018// first argument must be undefined or expand to a numeric
19// value. The above expands to:
20//
Jeff Thompson3d613fd2013-10-15 15:39:04 -070021// (NDNBOOST_MSVC) != 0 && (NDNBOOST_MSVC) < 1300
Jeff Thompsonf7d49942013-08-01 16:47:40 -070022//
23// When used for workarounds that apply to the latest known version
24// and all earlier versions of a compiler, the following convention
25// should be observed:
26//
Jeff Thompson3d613fd2013-10-15 15:39:04 -070027// #if NDNBOOST_WORKAROUND(NDNBOOST_MSVC, NDNBOOST_TESTED_AT(1301))
Jeff Thompsonf7d49942013-08-01 16:47:40 -070028//
29// The version number in this case corresponds to the last version in
30// which the workaround was known to have been required. When
Jeff Thompson3d613fd2013-10-15 15:39:04 -070031// NDNBOOST_DETECT_OUTDATED_WORKAROUNDS is not the defined, the macro
32// NDNBOOST_TESTED_AT(x) expands to "!= 0", which effectively activates
Jeff Thompsonf7d49942013-08-01 16:47:40 -070033// the workaround for any version of the compiler. When
Jeff Thompson3d613fd2013-10-15 15:39:04 -070034// NDNBOOST_DETECT_OUTDATED_WORKAROUNDS is defined, a compiler warning or
Jeff Thompsonf7d49942013-08-01 16:47:40 -070035// error will be issued if the compiler version exceeds the argument
Jeff Thompson3d613fd2013-10-15 15:39:04 -070036// to NDNBOOST_TESTED_AT(). This can be used to locate workarounds which
Jeff Thompsonf7d49942013-08-01 16:47:40 -070037// may be obsoleted by newer versions.
