Hi !
Seems to be an error because the migration to gcc 2.7.2.1 ?!
The configure script creates a temp file xgnu.c containing
these lines to fing out, if this is a GNU C compiler:
cat>xgnu.c<<EOF
#ifdef __GNUC__
yes;
#endif
EOF
isGNU()
{
$1 -E xgnu.c 2>&5 | egrep yes >/dev/null 2>&1
}
!!!!!!!!---------------^^^^^^^^ This egrep fails, since __GNUC__
isn't defined for some reason ... ?!?!
checkGCCVersion()
{
app=$1; shift
eval `$app -v 2>&1 | \
sed -n -e '/version/s/.* \([0-9]*\)\.\([0-9]*\).\([0-9]*\)/GCCdist=\1;GC
Cmajor=\2;GCCminor=\3/p'`
GCCversion="${GCCdist}.${GCCmajor}.${GCCminor}"; export GCCversion
required="$1$2$3"
actual="${GCCdist}${GCCmajor}${GCCminor}"
test "$actual" -ge "$required" >/dev/null 2>&1
}
for i in $CC gcc cc ncc dcc xlc c89 gcc2; do
if isGNU $i; then
checkGCCVersion $i 2 6 1 || continue;
ISGCC=yes
else
ISGCC=no
fi
This is what our gcc defines:
root{909} /usr/ports/comms/hylafax/work/hylafax-v3.0pl0 gcc -v -E -
gcc version 2.7.2.1
/usr/libexec/cpp -lang-c -v -undef -D__GNUC__=2 -D__GNUC_MINOR__=7
!!!--------------------------------------------^
-Dunix -Di386 -D__FreeBSD__=2 -D__unix__ -D__i386__ -D__FreeBSD__=2
-D__unix -D__i386 -Asystem(unix) -Asystem(FreeBSD) -Acpu(i386)
-Amachine(i386) -
GNU CPP version 2.7.2.1 (80386, BSD syntax)
#include "..." search starts here:
#include <...> search starts here:
/usr/include
End of search list.
So __GNUC__ should be defined ... Well,
Here what happens:
Good luck, I don't see the error .. :-((
Checksums OK.

Cannot locate a working ANSI C compiler.
If the compiler is in a non-standard location, set the environment
variable CC to the absolute pathname of the compiler that is to be used
and rerun this script.
If command line options are required for ANSI C compilation, set the
variable ENVOPTS to these options and rerun this script.
If you are trying to use GNU gcc, but you do not have version 2.6.1
or newer, then you must update your compiler (and probably libg++ as
well) before you can compile this software. Consult the documentation
for information about obtaining an up-to-date version of gcc.
configure:
configure: Unrecoverable error! Once you've corrected the problem rerun this script.
