From 4e5f593049be0c377d9a03af858d1d6253cefc7e Mon Sep 17 00:00:00 2001 From: Andrea Cavalli Date: Thu, 24 Dec 2020 22:43:59 +0100 Subject: [PATCH] Update tl-parser in release builds - Changed assertions to abort to allow the build to fail on release targets - Fixed some wrong assertion - Changed all stderr print to the respective macro - Fix output for release builds - Fix indentation Revamp build system with CMake - Completely removed config.h generation file, as it was not used anywere in the code - Removed all the old build files and switched to CMake (3.0+) - As tl-parser only uses zlib for crc32, removing the dependency makes the CMake file easier to maintain and makes the code building without third party code. The crc32 implementation was taken from abb3e47a984c2cc126522c48bd9c3b60ad14a46c. --- .gitignore | 9 +- CMakeLists.txt | 16 + Makefile.in | 48 - config.h.in | 96 - configure | 5018 ------------------------------------------ configure.ac | 33 - crc32.c | 663 ++++++ crc32.h | 59 + m4-ax_gcc_builtin.m4 | 168 -- portable_endian.h | 2 + tl-parser.c | 753 ++++--- tl-parser.h | 15 + tlc.c | 32 +- wingetopt.c | 82 + wingetopt.h | 32 + 15 files changed, 1326 insertions(+), 5700 deletions(-) create mode 100644 CMakeLists.txt delete mode 100644 Makefile.in delete mode 100644 config.h.in delete mode 100755 configure delete mode 100644 configure.ac create mode 100644 crc32.c create mode 100644 crc32.h delete mode 100644 m4-ax_gcc_builtin.m4 create mode 100644 wingetopt.c create mode 100644 wingetopt.h diff --git a/.gitignore b/.gitignore index a49c101..567609b 100644 --- a/.gitignore +++ b/.gitignore @@ -1,8 +1 @@ -Makefile -config.h -dep -objs -bin -autom4te.cache -config.log -config.status +build/ diff --git a/CMakeLists.txt b/CMakeLists.txt new file mode 100644 index 0000000..9092575 --- /dev/null +++ b/CMakeLists.txt @@ -0,0 +1,16 @@ +cmake_minimum_required(VERSION 3.0) +project(tl-parser) + +set(SOURCES crc32.h crc32.c tlc.c tl-parser.c tl-parser.h tl-parser-tree.h tl-tl.h portable_endian.h) + +if (WIN32) + list(APPEND SOURCES wingetopt.c wingetopt.h) +endif() +if (MSVC) + set(CMAKE_EXE_LINKER_FLAGS "/SUBSYSTEM:CONSOLE") +endif() + +add_executable(${PROJECT_NAME} ${SOURCES}) +if (NOT WIN32) + target_link_libraries(${PROJECT_NAME} m) +endif() diff --git a/Makefile.in b/Makefile.in deleted file mode 100644 index 446f49a..0000000 --- a/Makefile.in +++ /dev/null @@ -1,48 +0,0 @@ -srcdir=@srcdir@ - -CFLAGS=@CFLAGS@ -LDFLAGS=@LDFLAGS@ -CPPFLAGS=@CPPFLAGS@ -COMPILE_FLAGS=${CFLAGS} ${CPFLAGS} ${CPPFLAGS} ${DEFS} -Wall -Wextra -Werror -Wno-deprecated-declarations -fno-strict-aliasing -fno-omit-frame-pointer -ggdb -Wno-unused-parameter -fPIC - -EXTRA_LIBS=@LIBS@ -LOCAL_LDFLAGS=-rdynamic -ggdb ${EXTRA_LIBS} -LINK_FLAGS=${LDFLAGS} ${LOCAL_LDFLAGS} - -DEP=dep -EXE=bin -OBJ=objs -DIR_LIST=${DEP} ${EXE} ${OBJ} - -EXE_LIST=${EXE}/tl-parser - -OBJECTS=${OBJ}/tl-parser.o ${OBJ}/tlc.o - -DEPENDENCE=$(subst ${OBJ}/,${DEP}/,$(patsubst %.o,%.d,${OBJECTS})) -DEPENDENCE_LIST=${DEPENDENCE} - -INCLUDE=-I. -I${srcdir} -CC=@CC@ - -.SUFFIXES: - -.SUFFIXES: .c .h .o - -all: ${EXE_LIST} ${DIR_LIST} ${LIB_LIST} -create_dirs_and_headers: ${DIR_LIST} -create_dirs: ${DIR_LIST} - -${DIR_LIST}: - @test -d $@ || mkdir -p $@ - --include ${DEPENDENCE_LIST} - -${OBJECTS}: ${OBJ}/%.o: ${srcdir}/%.c | create_dirs_and_headers - ${CC} ${INCLUDE} ${COMPILE_FLAGS} -c -MP -MD -MF ${DEP}/$*.d -MQ ${OBJ}/$*.o -o $@ $< - -${EXE}/tl-parser: ${OBJECTS} - ${CC} $^ ${LINK_FLAGS} -o $@ - -clean: - rm -rf ${DIR_LIST} config.log config.status > /dev/null || echo "all clean" - diff --git a/config.h.in b/config.h.in deleted file mode 100644 index 6cffe69..0000000 --- a/config.h.in +++ /dev/null @@ -1,96 +0,0 @@ -/* config.h.in.
