Question

我正在尝试编译一个依赖于依赖于liblua51.so的共享库（so）的简单示例程序。我的源文件是example.c，这是我用来编译它的命令（用C编写）

cc -Wall -fPIC -ldl -o a.out -I./ste-linux/ste-interface-files/c/ -L./ste-linux/ste-shared-libraries/ example.c -lm -llua51 -lste -lm -ldl

我收到以下错误：

./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `sinh'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `ceil'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `atan2'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `tanh'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `cosh'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `fmod'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `acos'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `sin'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `atan'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `asin'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `exp'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `tan'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `cos'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `log'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `pow'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `log10'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `sqrt'
./ste-linux/ste-shared-libraries//liblua51.so: undefined reference to `floor'

我已经在stackoverflow上读了很多其他线程，说添加-lm标志会解决这个问题，但无论我在命令中放置-L和-lm -ldl，这些未定义的引用都不会消失。 / p>

我正在尝试在ubuntu 12.04 LTS上编译这个lib

请帮助

问题是我使用的共享库是使用不同版本的GCC构建的。在我从Ubuntu 11.04（从12.04 LTS）降级后，它已经解决了。
