I'm wondering about best practices for checking for programs like the
javac compiler. For instance, I currently have a line in my project's
configure.ac file that looks like this:
AC_CHECK_PROGS([JAVAC], ["gcj -C -ftarget=1.4 -fsource=1.4" "guavac
-target 1.4 -source 1.4" "jikes -target 1.4 -source 1.4" "javac -target
1.4 -source 1.4"])
Ugly. This line used to look like this before I needed to specify
particular source and target versions for my Java code:
AC_CHECK_PROGS([JAVAC], ["gcj -C" guavac jikes javac])
That wasn't bad, but now I'm duplicating flags all over the place just
because "gcj -C" requires a different set of options for JVM target and
source version specification than the other java compilers do. If they
were the same, I'd just append them to JAVACFLAGS and be done with it.
Any input would be appreciated.
Thanks,
John
