Hi,
The following simple configure.ac
========================= configure.ac ===========================
AC_INIT
AC_PROG_CC
AC_EGREP_CPP([notc99], [
#if 0
notc99
#endif
],
[gl_cv_func_printf_retval_c99="guessing no"],
[gl_cv_func_printf_retval_c99="guessing yes"])
AC_OUTPUT
===================================================================
processed with autoconf 2.60 or 2.61, yields a configure script that
cannot be processed on Solaris 2.4. On this machine I do
$ export PATH=/opt/SUNWspro/SC5.0/bin:/usr/bin:/usr/ccs/bin
$ export CC="cc -O"
$ ./configure
The result is that the configure script aborts:
checking for gcc... cc -O
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... no
checking whether cc -O accepts -g... yes
checking for cc -O option to accept ISO C89... none needed
checking how to run the C preprocessor... cc -O -E
checking for grep that handles long lines and -e... configure: error: no
acceptable grep could be found in
/opt/SUNWspro/SC5.0/bin:/usr/bin:/usr/ccs/bin:/usr/xpg4/bin
The configure script generated with autoconf 2.59, on the other hand, works:
checking for gcc... cc -O
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... no
checking whether cc -O accepts -g... yes
checking for cc -O option to accept ANSI C... none needed
checking how to run the C preprocessor... cc -O -E
checking for egrep... egrep
configure: creating ./config.status
No problem on Solaris 2.5.1.
This means that autoconf >= 2.60 has dropped support for Solaris 2.4, right?
