Freeglut程序編譯運行，但時，顯示了錯誤：libglut.so.3：無法打開共享對象文件

Question

這是我的計劃：

#include </usr/local/include/GL/glut.h> 

int main(int argc, char **argv) 
{ 
    glutInit(&argc, argv); 
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA); 
    glutInitWindowPosition(100,100); 
    glutInitWindowSize(320,320); 
    glutCreateWindow("Lighthouse3D- GLUT Tutorial"); 
} 

與編譯：顯示

g++ -lglut -L/usr/local/lib/ -o start start.cpp;./start

錯誤：

./start: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory

該文件存在。

bashprompt> locate libglut.so.3
/usr/local/lib/libglut.so.3
/usr/local/lib/libglut.so.3.9.0

還曾試圖：

LD_RUN_PATH="/usr/local/lib/"
g++ -lglut -LLIBDIR -o start start.cpp;./start with no luck.

這些是在安裝（如果這能幫助）顯示的信息：

---------------------------------------------------------------------- Libraries have been installed in:
/usr/local/lib If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the -LLIBDIR' flag during linking and do at least one of the following:
- add LIBDIR to the LD_LIBRARY_PATH' environment variable during execution
- add LIBDIR to the LD_RUN_PATH' environment variable during linking
- use the -Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages.

Answer 1

你LD_RUN_PATH嘗試是非常接近，但它應該是LD_LIBRARY_PATH ：

export LD_LIBRARY_PATH=/usr/local/lib 
./start 

這個技巧從安裝也很方便：

have your system administrator add LIBDIR to `/etc/ld.so.conf'

如果你這樣做，你就不需要做LD_LIBRARY_PATH事情。
