From d986c98e471e21aee0129e1fe1a7ba3059069256 Mon Sep 17 00:00:00 2001 From: Rodrigo Mesquita Date: Fri, 12 May 2023 12:10:08 +0100 Subject: configure: Drop unused AC_PROG_CPP In configure, we were calling `AC_PROG_CPP` but never making use of the $CPP variable it sets or reads. The issue is $CPP will show up in the --help output of configure, falsely advertising a configuration option that does nothing. The reason we don't use the $CPP variable is because HS_CPP_CMD is expected to be a single command (without flags), but AC_PROG_CPP, when CPP is unset, will set said variable to something like `/usr/bin/gcc -E`. Instead, we configure HS_CPP_CMD through $CC. --- configure.ac | 3 --- 1 file changed, 3 deletions(-) diff --git a/configure.ac b/configure.ac index 899a6e65a8..0005d56657 100644 --- a/configure.ac +++ b/configure.ac @@ -465,9 +465,6 @@ MAYBE_OVERRIDE_STAGE0([ar],[AR_STAGE0]) dnl make extensions visible to allow feature-tests to detect them lateron AC_USE_SYSTEM_EXTENSIONS -dnl ** figure out how to invoke the C preprocessor (i.e. `gcc -E`) -AC_PROG_CPP - # --with-hs-cpp/--with-hs-cpp-flags FP_CPP_CMD_WITH_ARGS(HaskellCPPCmd, HaskellCPPArgs) AC_SUBST([HaskellCPPCmd]) -- cgit v1.2.1
