dnl Process this file with autoconf to produce a configure script.
|
||||
|
||||
dnl This configure.in file has been hacked around quite a lot as a result of
|
||||
dnl patches that various people have sent to me (PH). Sometimes the information
|
||||
dnl I get is contradictory. I've tried to put in comments that explain things,
|
||||
dnl but in some cases the information is second-hand and I have no way of
|
||||
dnl verifying it. I am not an autoconf or libtool expert!
|
||||
|
||||
dnl This is required at the start; the name is the name of a file

||||

AC_PROG_CC

dnl Test for C++ for the C++ wrapper libpcrecpp. It seems, however, that

dnl AC_PROC_CXX will set $CXX to "g++" when no C++ compiler is installed, even
|
||||
dnl though that is completely bogus. (This may happen only on certain systems
|
||||
dnl with certain versions of autoconf, of course.) An attempt to include this
|
||||
dnl test inside a check for want_cpp was criticized by a libtool expert, who
|

dnl tells me that it isn't allowed.

AC_PROG_CXX
|
||||
|
||||
dnl The icc compiler has the same options as gcc, so let the rest of the

dnl configure script think it has gcc when setting up dnl options etc.
|

dnl This is a nasty hack which no longer seems necessary with the update

dnl to the latest libtool files, so I have commented it out.

dnl We need to find a compiler for compiling a program to run on the local host
|

dnl while building. It needs to be different from CC when cross-compiling.
|

dnl There is a macro called AC_PROG_CC_FOR_BUILD in the GNU archive for
|
||||
dnl figuring this out automatically. Unfortunately, it does not work with the
|
||||
dnl latest versions of autoconf. So for the moment, we just default to the
|
||||
dnl same values as the "main" compiler. People who are cross-compiling will
|

dnl just have to adjust the Makefile by hand or set these values when they
