如何编译c99到c89转换器铛？ [英] How to compile c99-to-c89 convertor with clang?

问题描述

我试图在VisualStudio中编译ffmpeg，其中一步是编译 c99 -to-c89 代码，根据 this post。我设法创建clang.exe，但我怎么编译c99-to-c89代码？

I'm trying to compile ffmpeg in windows for VisualStudio and one of the step is to compile c99-to-c89 code with clang according to this post. I managed to create clang.exe but how I compile c99-to-c89 code with it?

我改变了一点点c99到c89的makefile，所以 CC 变量现在指向clang.exe编译器而不是cl.exe

I changed a little bit the makefile in c99-to-c89 so CC variable points now to clang.exe compiler and not cl.exe

EXT=.exe

all: c99conv$(EXT) c99wrap$(EXT)

CLANGDIR=C:/build
CC=C:/build/bin/Release/clang.exe
CFLAGS=-nologo -Z7 -D_CRT_SECURE_NO_WARNINGS=1 -Dpopen=_popen -Dunlink=_unlink -Dstrdup=_strdup -Dsnprintf=_snprintf -I. -I$(CLANGDIR)/tools/clang/include
LDFLAGS=-nologo -Z7 $(CLANGDIR)/lib/Release/libclang.lib

clean:
    rm -f c99conv$(EXT) c99wrap$(EXT) convert.o compilewrap.o
    rm -f unit.c.c unit2.c.c

test1: c99conv$(EXT)
    $(CC) -P unit.c -Fiunit.prev.c
    ./c99conv unit.prev.c unit.post.c
    diff -u unit.{prev,post}.c

test2: c99conv$(EXT)
    $(CC) -P unit2.c -Fiunit2.prev.c
    ./c99conv unit2.prev.c unit2.post.c
    diff -u unit2.{prev,post}.c

test3: c99conv$(EXT)
    $(CC) $(CFLAGS) -P -Ficonvert.prev.c convert.c
    ./c99conv convert.prev.c convert.post.c
    diff -u convert.{prev,post}.c

c99conv$(EXT): convert.o
    $(CC) -Fe$@ $< $(LDFLAGS) $(LIBS)

c99wrap$(EXT): compilewrap.o
    $(CC) -Fe$@ $< $(LDFLAGS)

%.o: %.c
    $(CC) $(CFLAGS) -Fo$@ -c $<

但是当我运行 make clang：error：不支持使用内部gcc -Z选项'-Z7'。我想在 CFLAGS 和 LDFLAGS 中的问题，但我不知道如何解决它，因为缺乏知识makefile和clang。

but when I run make command I get clang: error: unsupported use of internal gcc -Z option '-Z7'. I guess the problem in CFLAGS and LDFLAGS but I don't know how to fix it because the lack of knowledge in makefile and clang.

推荐答案

如果有人还需要，libav的家伙给我提供了此链接下载二进制文件 c99conv.exe ， c99wrap.exe ， makedef

If someone still needs, the guys from libav provided me with this link to download the binaries c99conv.exe, c99wrap.exe, makedef
