  • How to compile c99-to-c89 convertor with clang ?

    27 septembre 2016, par theateist

    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 ?

    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 $<

    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.

  • Convert audio files to mp3 using ffmpeg

    I need to convert audio files to mp3 using ffmpeg.

    When i write the command as ffmpeg -i audio.ogg -acodec mp3 newfile.mp3, I get the error :

    I also ran this command :

    and got this in response :

    I guess that the mp3 codec isnt installed. Am I right here ? Can anyone help me out here ?
