Hi,
I got into troubles when running an Autoconf 2.59 generated `configure'
script on an IRIX64 6.2 machine.
The first problem I had is that I was unable to run `configure' and
`config.status' as is. Both scripts contain the following line:
# Work around bugs in pre-3.0 UWIN ksh.
$as_unset ENV MAIL MAILPATH
On IRIX (whose `sh' does support `unset'), this causes the script to
abort with the following error message:
configure[35]: ENV: readonly
(35 being the number of the line where the `unset' occurs). Is there a
way to work around this problem?
The second problem I had was when checking for function `main' in some
libraries, like:
AC_CHECK_LIB([ACE], [main],
[LIBS="-lACE $LIBS"],
[AC_MSG_ERROR([Could not find libACE.])])
(since there are C++ libraries, I cannot check for actual function name
such as `ACE::init ()' since Autoconf would declare it "as is" which
won't work). SGI CC C++ compiler produces an error with a message like:
function "main" may not be called or have its address taken
Compaq's CXX outputs a similar message except that it only considers it
as a warning. With SGI CC, this causes `configure' to think that the
library was not found. Using `CHECK_LIB' with an empty function name
doesn't work. So, again, what would be the best solution to work around
this problem?
Thanks,
Ludovic.
