I managed to compiled emulators/mame in an rpi4.
Some thoughts about the port:
In patch-makefile
ifeq ($(OS),windows)
ifeq (posix,$(SHELLTYPE))
-GCC_VERSION := $(shell $(TOOLCHAIN)$(subst @,,$(CC)) -dumpversion 2>
/dev/null)
-CLANG_VERSION := $(shell $(TOOLCHAIN)$(subst @,,$(CC)) --version 2> /dev/null| head
-n 1 | grep clang | sed
"s/^.*[^0-9]\([0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\).*$$/\1/" | head -n 1)
+GCC_VERSION := $(shell cc -dumpversion 2> /dev/null)
+CLANG_VERSION := $(shell cc --version 2> /dev/null | head -n 1 | grep -e
'version [0-9]\.[0-9]\.[0-9]' -o | sed -e 's,version ,,' | tail -n 1)
PYTHON_AVAILABLE := $(shell $(PYTHON) --version > /dev/null 2>&1 && echo
python)
GIT_AVAILABLE := $(shell git --version > /dev/null 2>&1 && echo git)
else
This doesn't make any sense, this part is only processed on windows.
But you'd need 'grep clang' anyway or CLANG_VERSION would be set
even if the compiler is gcc. Note that if this weren't the case,
you could just use -dumpversion.
CC ends up defined to gcc by default by makefile, but using OVERRIDE_CC
isn't sufficient because CLANG_VERSION is left out of the conditional
code:
[...]
ifdef OVERRIDE_CC
GCC_VERSION := $(shell $(TOOLCHAIN)$(subst @,,$(OVERRIDE_CC)) -dumpversion
2> /dev/null)
else
GCC_VERSION := $(shell $(TOOLCHAIN)$(subst @,,$(CC)) -dumpversion 2>
/dev/null)
endif
ifeq ($(findstring emcc,$(CC)),emcc)
CLANG_VERSION := $(shell $(TOOLCHAIN)$(subst @,,$(CC)) -v 2>&1 >/dev/null
| grep 'clang version' | head -n 1 | grep -e 'version [0-9]\+\.[0-9]\+
\(\.[0-9]\+\)\?' -o | grep -e '[0-9]\+\.[0-9]\+\(\.[0-9]\+\)\?' -o | tail -n 1)
else
CLANG_VERSION := $(shell $(TOOLCHAIN)$(subst @,,$(CC)) --version 2>
/dev/null | head -n 1 | grep -e 'version [0-9]\+\.[0-9]\+\(\.[0-9]\+\)\?' -o
| grep -e '[0-9]\+\.[0-9]\+\(\.[0-9]\+\)\?' -o | tail -n 1)
endif
PYTHON_AVAILABLE := $(shell $(PYTHON) --version > /dev/null 2>&1 && echo python)
GIT_AVAILABLE := $(shell git --version > /dev/null 2>&1 && echo git)
endif
ifeq ($(CLANG_VERSION),)
$(info GCC $(GCC_VERSION) detected)
else
$(info Clang $(CLANG_VERSION) detected)
ifneq ($(TARGETOS),asmjs)
ifeq ($(ARCHITECTURE),_x64)
ARCHITECTURE := _x64_clang
else
ifneq ($(filter arm64%,$(UNAME_M)),)
ARCHITECTURE := _arm64_clang
else
ARCHITECTURE := _x86_clang
endif
endif
endif
endif
[...]
Even correcting this, CLANG_VERSION is not detected because grep
is using gnu basic regular expression syntax, in openbsd BRE there
is no + nor ? [re_format(7)].
Here is a diff only tested on arm64.
I left out emcc of the ifdef OVERRIDE_CC statement, add it if you
think it will be of any use in the future.
