QT工程中加入.so文件 [复制链接]

我在linux下写好了串口程序，生成了。so的文件

我在我的工程中pro文件中加了LIBS +=-L/serial/bin -lserial

但是编译时还是报错说没有serial这个库。

各位，网上和书上都是这么做的，但是我这就是不对

希望有你的指点

copy **.so to /usr/lib/

侠客

是把。so文件拷到linux的usr/bin下？？

可以解释哈不？？

Sorry copy **.so to /usr/lib .you try it, I don't know the reason

bin下有这个库?

I'm sorry
copy *so to /usr/lib/

我试了。但是还是不行哈，编译时还是说没有这个库

You may need to add the full path to LIBS +=-L/home/yourname/serial/bin -lserial
or
Open your Makefile in an editor
copy so file to /serial/bin
then add -L/home/yourname/serial/bin -lserial to LIBS =

if you do not know what the full path is, go to /serial/bin and type pwd to get the full path.

-L/serial/bin tells where your so is
-lserial means link it.

Normally you put a .so file in a lib, not in bin(for binary executable) since it is a dynamic library

You do not need to do this although it may work.
The reason why it works is that by default the environment variable LD_LIBRARY_PATH includes /usr/lib
If you copy so file there, path has been set already.
Type env to see if LD_LIBRARY_PATH has /usr/lib
