pro*c 编译包含libxml2的头文件不通过

[temporaryname]

我现在在机器上装了libxml2了，用c写了一些基础函数，暂时叫xml.c和xml.h，我然后写了一个pro.pc，调用xml.h中的函数，当然xml.h中的函数涉及到libxml2中的内容

如果单独写一个c的makefile是可以编译xml.h和xml.c的，现在我写了个pc的makefile，包含xml.h后就编译通过不了了

报很多类似的错误，好像是数据类型的转换问题

很多类似的错误，目前我不知道怎么解决。
我本想先把pc编译成c文件后看看，但我在makefile中
.pc.o:
$(PROC) $(PROCFLAGS) include=$(BCIAINCLUDE) include=$(LIBXML2INCLUDE) iname=$*
$(CC) $(CFLAGS) -I$(BCIAINCLUDE) -I$(LIBXML2INCLUDE) -o $*.o -c $*.c
把这段禁掉后，makefile显示不知道怎么编译
然后我把上段变成(在proc是不要包含libxml2的头文件)
.pc.o:
$(PROC) $(PROCFLAGS) include=$(BCIAINCLUDE) iname=$*
$(CC) $(CFLAGS) -I$(BCIAINCLUDE) -I$(LIBXML2INCLUDE) -o $*.o -c $*.c
显示找不到LIBXML2的头文件

如果有libxml2和pro*c中有类型或者什么冲突的话，不知道有没有其它的解决办法呢

我快要疯了，在线等，等待高手解疑
