我在编译一些下载的文件（用于学术目的）时遇到了一些困难。我运行了以下命令：
cd tmp/Detri_2.6.a/detri
然后 make detri_new CC=gcc 从提取到 /tmp 的相关文件和文件夹构建库。
输出如下：
tmp/Detri_2.6.a/detri$ make detri_new CC=gcc
g++ Makefile.cpp -o Makefile

我还没有编写 makefile.cpp（请记住这是我使用 ubuntu 并做此类事情的第一周），但以前，编译器会尝试在 makefile.tmp 中构建并查找错误，而不是在 .cpp 文件中。现在，正如输出所示，它不会超出尝试读取 .cpp 文件的程度。
我有点迷路了......
谢谢
更新：我已尝试以下评论中建议的操作，即运行：make -k TMPMK=Makefile.tmp detri_new CC=gcc
但我仍然有相同的（窗口充满的）输出错误，以及一些新的错误。
如果这有帮助的话，代码是从以下获取的网站
编辑：缩短错误输出部分并更清楚地解释问题。
以下是 makefile：

据我所知，这个 Makefile.cpp 用于使用 C 预处理器生成 Makfeile。如你所见，在 Makefile.cpp 中有一行：
/* USAGE: cpp -P ${CPPMK} > ${TMPMK}; make -k TMPMK=${TMPMK} -f ${TMPMK} ... */
这意味着您应该运行 C 预处理器 (cpp) 来获取真正的 Makefile。通过键入，您将基于cpp -P Makefile.cpp > Makefile.tmp生成。根据此使用注释，您应该将生成的文件作为变量值传递给 make，例如。希望这对您有所帮助。Makefile.tmpMakefile.cppMakefile.tmpTMPMKmake -k TMPMK=Makefile.tmp detri_new CC=gcc
