对“dlopen”的未定义引用 'dlsym' dlcose'
undefined reference to `dlopen' 'dlsym' dlcose'
我正在使用 UBUNTU 12.04 并尝试为设计 Space 探索安装多立方体资源管理器。
我是这些 makefile 和 linux 内部人员的新手。
我按照这些步骤进行安装
./configure
make
然后我收到错误消息。以下是日志（为了便于阅读，重新格式化了命令行）。

错误的可能原因是什么以及如何解决？我检查了博客中的许多早期帖子。但是无法解决。
在目标文件之后列出库，在它们之前不。重写当前的构建规则：
m3explorer: $(M3EXPLORER_TARGETS)
$(CXX) $(OTHERLINKFLAGS) $^ -o $@
如：
m3explorer: $(M3EXPLORER_TARGETS)
$(CXX) -o $@ $^ $(OTHERLINKFLAGS)
就个人而言，我也会在 link 行中包含 $(CXXFLAGS)：
m3explorer: $(M3EXPLORER_TARGETS)
$(CXX) $(CXXFLAGS) -o $@ $^ $(OTHERLINKFLAGS)

错误的可能原因是什么以及如何解决？我检查了博客中的许多早期帖子。但是无法解决。
在目标文件之后列出库，在它们之前不。重写当前的构建规则：
m3explorer: $(M3EXPLORER_TARGETS)
$(CXX) $(OTHERLINKFLAGS) $^ -o $@
如：
m3explorer: $(M3EXPLORER_TARGETS)
$(CXX) -o $@ $^ $(OTHERLINKFLAGS)
就个人而言，我也会在 link 行中包含 $(CXXFLAGS)：
m3explorer: $(M3EXPLORER_TARGETS)
$(CXX) $(CXXFLAGS) -o $@ $^ $(OTHERLINKFLAGS)
