錯誤：在包含外部庫後程序中出現'\ 224'

我是C++新手。我試圖使用libserial 錯誤：在包含外部庫後程序中出現' 224'

bitmap_test.cpp

#include <SerialStream.h> 
#include <cstdio> 
#include <cstdlib> 
#include <iostream> 
#include <string> 

using namespace LibSerial ; 

int main() 
{ 
    SerialStream serial_port("/dev/ttyS0") ; 
    return 0; 
}

錯誤：

In file included from <command-line>:0:0: 
    /usr/local/lib/libserial.a:118:520: error: null character(s) ignored [-Werror] 
    In file included from <command-line>:0:0:

...

COMPILER  = -c++ 
OPTIONS  = -ansi -pedantic-errors -Wall -Wall -Werror -Wextra -o 
LINKER_OPT = -L/usr/lib -lserial -include/usr/local/lib/libserial.a -lstdc++ -lm 

all: bitmap_test 

bitmap_test: bitmap_test.cpp bitmap_image.hpp 
    $(COMPILER) $(OPTIONS) bitmap_test bitmap_test.cpp $(LINKER_OPT)

我做研究和了解它是一個問題的生成文件編碼，但不知道如何解決它。任何幫助，非常感謝。

編輯： 圖書館是在正確的道路：

/sbin/ldconfig -p | grep libserial 
    libserial.so.0 (libc6,x86-64) => /usr/local/lib/libserial.so.0 
    libserial.so.0 (libc6,x86-64) => /usr/lib/libserial.so.0 
    libserial.so (libc6,x86-64) => /usr/local/lib/libserial.so 
    libserial.so (libc6,x86-64) => /usr/lib/libserial.so

但是，如果我改變Makefile文件的建議，我都會有這樣的問題：

c++ -ansi -pedantic-errors -Wall -Wall -Werror -Wextra -o bitmap_test bitmap_test.cpp -L/usr/local/lib -lstdc++ -lm -lserial 
bitmap_test.cpp: In function ‘int main()’:

究竟應該選擇'-include/usr/local/lib/libserial.a'實際上是這樣嗎？我很確定這是罪魁禍首。 –

由eclipse生成的生成文件顯示該選項，因爲我包含來自C/C++構建/設置/工具設置/包括 –

的文件我覺得我只是將include內部make文件更改爲這個-L/usr/local/lib/libserial.la –

流浪人物通常有與源編碼有關。

「空字符忽略」診斷通常會指示源代碼是UTF-16或UTF-32。

然而，makefile文件顯示您處理一個靜態庫作爲強制包含文件：

-include/usr/local/lib/libserial.a

隨着我的G ++在Windows中：

 
> g++ -v --help 2>&1 | find "-include " 
    --include     This switch lacks documentation 
    -include <file>    Include the contents of <file> before other

感謝您的回覆。你能告訴我應該如何包含.a庫文件嗎？正如你所看到的，我也嘗試過-lserial，並且在/ usr/local/lib中，我有libserial.a和libserial.so，但它不起作用 –

希望'-lserial'能做到這一點。請注意，前綴'lib'和文件擴展名'.a'被刪除。鏈接器添加，因爲它搜索。 –

@HakeemSaad，我唯一能想到的就是在命令末尾加上'-lserial'。這有時可以幫助解決問題。你也可以參考http://stackoverflow.com/questions/12573816/what-is-an-undefined-reference-unresolved-external-symbol-error-and-how-doi-i-fix。 – chris
