在编译 TrueCrypt 时，我得到“对符号 'dlclose@@GLIBC_2.2.5' 的未定义引用”

Question

我正在尝试从 Ubuntu 13.04 上的源代码编译 TrueCrypt 7.1a。但是make在链接过程中失败并出现以下错误：

Linking truecrypt
/usr/bin/ld: /home/user/truecrypt-7.1a-source/tc2/Volume/Volume.a(SecurityToken.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
/usr/bin/ld: note: 'dlclose@@GLIBC_2.2.5' is defined in DSO /lib/x86_64-linux-gnu/libdl.so.2 so try adding it to the linker command line
/lib/x86_64-linux-gnu/libdl.so.2: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make[1]: *** [truecrypt] Error 1
make: *** [all] Error 2

我该如何解决？

将环境变量设置LIBS为-ldl：

LIBS=-ldl make
