使用 gcc 链接到库时出现问题

我今天从头开始安装了 SFML，这样我就可以开发游戏了。我下载了源代码，运行 sudo make install，尝试编译我的一个旧项目，但无法正确链接。因此，我尝试运行一个更简单的项目：教程中的示例之一。我尝试专门编译这个，但我得到了这些错误：

g++ -o atest test.cpp -lsfml-graphics -lsfml-window -lsfml-system /tmp/ccaa86fR.o: In function `main':
test.cpp:(.text+0x1d2): undefined reference to `gluPerspective'
collect2: ld returned 1 exit status
make: *** [test] Error 1

尝试一个更简单的项目，初始教程，我在编译时没有遇到问题。但是，当我尝试运行它时，出现此错误：

./atest: error while loading shared libraries: libsfml-graphics.so.1.6: cannot open shared object file: No such file or directory

我检查过，文件确实安装到了 /usr/local/lib/ ，据我所知，这是它们应该去的地方。我在这里做错了什么？

原文

I installed SFML from scratch today so I could work on a game. I downloaded the source, ran sudo make install, tried compiling one of my old projects, and I couldn't get it to link properly. So I tried running a simpler project: one of the samples in the tutorials. I tried to compile this one specifically, but I get these errors:

g++ -o atest test.cpp -lsfml-graphics -lsfml-window -lsfml-system /tmp/ccaa86fR.o: In function `main':
test.cpp:(.text+0x1d2): undefined reference to `gluPerspective'
collect2: ld returned 1 exit status
make: *** [test] Error 1

Trying an even simpler project, the one in the initial tutorial, I don't run into problems compiling. However, when I try to run it, I get this error:

./atest: error while loading shared libraries: libsfml-graphics.so.1.6: cannot open shared object file: No such file or directory

I checked, and the files did install to /usr/local/lib/ which is where they're supposed to go as far as I know. What am I doing wrong here?

-lGLU 应该修复第一个错误，对于第二个错误，请确保 /usr/local/lib/ 位于您的 ldconfig 搜索路径中 (/etc/ld. so.conf 和 /etc/ld.so.conf.d/* 在 Ubuntu 下)，并且您运行了 ldconfig: sudo ldconfig -v 然后尝试运行再次。

另请参阅man ldconfig
