Hi, The attached patch modifies configure to generate assignments in config.make with the = operator instead of ?=. That's to prevent build settings from being overridden through the environment, which might be surprising/dangerous.
All the best. Mario -- https://parenteses.org/mario

This change uses = for assigments in config.make, which prevents settings in config.make from being overridden through the environment. Build settings configured in config.make can still be overridden in make invocations as command line arguments (e.g., make PREFIX=...). --- configure | 32 ++++++++++++++++---------------- 1 file changed, 16 insertions(+), 16 deletions(-) diff --git a/configure b/configure index d09a045f..5672f80a 100755 --- a/configure +++ b/configure @@ -258,22 +258,22 @@ else fi echo "# GENERATED BY configure" > config.make -echo "PLATFORM ?= $platform" >> config.make -echo "PREFIX ?= $prefix" >> config.make -test -n "$debug" && echo "DEBUGBUILD ?= 1" >> config.make -test -n "$static" && echo "STATICBUILD ?= 1" >> config.make -test -n "$CC" && echo "C_COMPILER ?= $cccmd" >> config.make -test -n "$linker" && echo "LINKER ?= $linker" >> config.make -test -n "$CFLAGS" && echo "C_COMPILER_OPTIMIZATION_OPTIONS ?= $CFLAGS" >> config.make -test -n "$host" && echo "HOSTSYSTEM ?= $host" >> config.make -test -n "$target" && echo "TARGETSYSTEM ?= $target" >> config.make -test -n "$pprefix" && echo "PROGRAM_PREFIX ?= $pprefix" >> config.make -test -n "$psuffix" && echo "PROGRAM_SUFFIX ?= $psuffix" >> config.make -test -n "$tprefix" && echo "TARGET_PREFIX ?= $tprefix" >> config.make -test -n "$srcdir" && echo "SRCDIR ?= $srcdir" >> config.make -test -n "$vardir" && echo "VARDIR ?= $vardir" >> config.make -test -n "$chicken" && echo "CHICKEN ?= $chicken" >> config.make -test -n "$pobjs" && echo "PROFILE_OBJECTS ?= $pobjs" >> config.make +echo "PLATFORM = $platform" >> config.make +echo "PREFIX = $prefix" >> config.make +test -n "$debug" && echo "DEBUGBUILD = 1" >> config.make +test -n "$static" && echo "STATICBUILD = 1" >> config.make +test -n "$CC" && echo "C_COMPILER = $cccmd" >> config.make +test -n "$linker" && echo "LINKER = $linker" >> config.make +test -n "$CFLAGS" && echo "C_COMPILER_OPTIMIZATION_OPTIONS = $CFLAGS" >> config.make +test -n "$host" && echo "HOSTSYSTEM = $host" >> config.make +test -n "$target" && echo "TARGETSYSTEM = $target" >> config.make +test -n "$pprefix" && echo "PROGRAM_PREFIX = $pprefix" >> config.make +test -n "$psuffix" && echo "PROGRAM_SUFFIX = $psuffix" >> config.make +test -n "$tprefix" && echo "TARGET_PREFIX = $tprefix" >> config.make +test -n "$srcdir" && echo "SRCDIR = $srcdir" >> config.make +test -n "$vardir" && echo "VARDIR = $vardir" >> config.make +test -n "$chicken" && echo "CHICKEN = $chicken" >> config.make +test -n "$pobjs" && echo "PROFILE_OBJECTS = $pobjs" >> config.make echo echo "now run ${mkcmd} to build the system" -- 2.47.3
