Hi, This is with autoconf 2.71.
I use autom4te to create a script and discovered that the script exits when the else clause in AS_IF is reached. It seems it's caused by the combination that function as_fn_nop() is called in the else clause and that I have 'set -e' earlier in the script.
I suppose my workaround will be that I remove the 'set -e', but the behaviour is quite unexpected. I've boiled down the script to a minimal test case that illustrates the behaviour
cat > foo.m4sh <<EOF AS_INIT AS_ME_PREPARE set -e if test x"$1" = x"apple"; then echo apple; else echo not apple; fi AS_IF([test x"$1" = x"orange"], [AS_ECHO([orange])], [AS_ECHO([not orange])]) EOF autom4te -l M4sh -o foo.sh foo.m4sh sh -x foo.sh hello world ... + set -e + test x = xapple + echo not apple not apple + test x = xorange + as_fn_nop + return 1 i.e., it exits before printing anything about the orange Thanks, Peter
