获取包含第三方库的编译错误

我通过包含第三方库来尝试下面的c程序。 该程序和一个makefile位于b \ flite-1.4-release \ Learnin_though_example文件夹中。 th flite库位于b \ flite-1.4-release \ build \ i386-linux-gnu \ lib中，头文件位于b \ flite-1.4-release \ include中。
我假设我已经为makefile提供了搜索文件的正确路径。 但它没有识别它，我得到一个错误，因为，
make clean all rm -f *.o gcc -c eg1.c eg1.c:2:19: error: flite.h: No such file or directory eg1.c:3: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token eg1.c: In function ‘main’: eg1.c:6: error: ‘cst_voice’ undeclared (first use in this function) eg1.c:6: error: (Each undeclared identifier is reported only once eg1.c:6: error: for each function it appears in.) eg1.c:6: error: ‘v’ undeclared (first use in this function) eg1.c:7: error: ‘cst_wave’ undeclared (first use in this function) eg1.c:7: error: ‘w’ undeclared (first use in this function) eg1.c:17: error: ‘CST_OK_FORMAT’ undeclared (first use in this function) make: *** [eg1.o] Error 1
请帮助我理解我正在做的错误
编辑：
我根据matt的指导修改了makefile：
all:compile compile:eg1.o gcc $(INC_DIR) $(LIB_DIR) -o $@ $^ $(LIBS) eg1.o:eg1.c gcc $(INC_DIR) -o $@ -c $^ LIBS_DIR = -L../build/i386-linux-gnu/lib INC_DIR = -I../include LIBS = -lflite -lflite_cmulex -lflite_cmu_time_awb -lflite_cmu_us_kal16 -lflite_cmu_us_kal -lflite_cmu_usenglish -lflite_cmu_us_slt clean: rm -f *.o
但是我正在使用“make clean all”命令编译的ifferent错误，
rm -f *.o gcc -I../include -o eg1.o -c eg1.c gcc -I../include -o compile eg1.o -lflite -lflite_cmulex -lflite_cmu_time_awb -lflite_cmu_us_kal16 -lflite_cmu_us_kal -lflite_cmu_usenglish -lflite_cmu_us_slt /usr/bin/ld: cannot find -lflite collect2: ld returned 1 exit status make: *** [compile] Error 1

你害怕说，你的makefile完全崩溃了。
基本的Makefile语法是：
target: pre-requisite(s) Stuff to do to build target from pre-reqs (if required)
所以这是错误的， eg1.o不能成为建立自己的先决条件。
compile:eg1.o gcc -o eg1.o
你应该有：
eg1.o: eg1.c gcc $(INC_DIR) -o $@ -c $^
（ $@是目标， $^所有预先要求。）
然后你可以：
myexe: eg1.o gcc $(INC_DIR) $(LIBS_DIR) -o $@ $^ $(LIBS)
这将从myexe生成eg1.o 。 并且你的all规则应该是all: myexe ，没有配方（没有命令），并且在你拥有它的顶部。
然后你已经将你的include目录和库目录混淆了。 -I用于包含路径， -L用于库路径。
将变量定义放在规则之前，这是更常见/通常的。 并且不要在-L / -I和它-I的路径之间放置一个空格。
要搜索的include目录由-I标志指定，而不是-L 。
更改：
LIBS_DIR = -I /home/b/flite-1.4-release/build/i386-linux-gnu/lib INC_DIR = -L /home/b/flite-1.4-relase/include
至：
LIBS_DIR = -L /home/b/flite-1.4-release/build/i386-linux-gnu/lib INC_DIR = -I /home/b/flite-1.4-relase/include
