| Brian Silverman | 9c614bc | 2016-02-15 20:20:02 -0500 | [diff] [blame^] | 1 | dnl Check for the presence of the Sun Studio compiler. |
| 2 | dnl If Sun Studio compiler is found, set appropriate flags. |
| 3 | dnl Additionally, Sun Studio doesn't default to 64-bit by itself, |
| 4 | dnl nor does it automatically look in standard Solaris places for |
| 5 | dnl 64-bit libs, so we must add those options and paths to the search |
| 6 | dnl paths. |
| 7 | |
| 8 | dnl TODO(kenton): This is pretty hacky. It sets CXXFLAGS, which the autoconf |
| 9 | dnl docs say should never be overridden except by the user. It also isn't |
| 10 | dnl cross-compile safe. We should fix these problems, but since I don't have |
| 11 | dnl Sun CC at my disposal for testing, someone else will have to do it. |
