GNU assembler not found, install/update gas-preprocessor

加上 --disable-asm 选项

完整Makefile解决方案示意如下：


CFLAGS = -g -O2
SOURCE_FOLDER_NAME = ffmpeg-4.2.2-full
CFLAGS += -Werror=incompatible-pointer-types -Werror=uninitialized -Werror-implicit-function-declaration

.PHONY: all install uninstall clean distclean

ECFLAGS  = -I$(ROOT_SOURCE_FOLDERINC_DIR)
ELDFLAGS = -L$(ROOT_SOURCE_FOLDERPREFIX_DIR)/lib -Wl,-rpath-link=$(ROOT_SOURCE_FOLDERPREFIX_DIR)/lib
CFLAGS  += $(CPPFLAGS)

PKG_CONFIG_PATH = $(ROOT_SOURCE_FOLDERPREFIX_DIR)/lib/pkgconfig
PKG_CONFIG_LIBDIR = $(PKG_CONFIG_PATH)
CXXFLAGS = $(CFLAGS)

export CPPFLAGS CFLAGS LDFLAGS CXXFLAGS LIBS LD_LIBRARY_PATH PKG_CONFIG_PATH PKG_CONFIG_LIBDIR
export AR AS CPP LD CXX CC RANLIB NM STRIP OBJCOPY READELF OBJDUMP
