自定义.m4宏不能与configure.ac一起使用

Question

我正在尝试通过使用.configure脚本更容易地安装来更新一个神秘的科学F77程序以适应现代世界。然而，事实证明，这比宣传的要困难得多。我拖入21世纪的程序需要SuperMongo绘图库，我正在尝试弄清楚如何让SuperMongo找到必要的github库(libplotsub.a、libdevices.a和libutils.a)的正确路径，而不是让您查看代码的核心，我创建了一个框架github存储库(https://github.com/Acetylene5/autoconf_testing)。

主程序是test.f，它调用junk.f文件。这两个文件都包含Stuff.com公共块。F文件调用两个函数:一个(dcopy)来自LAPACK库，另一个(drawcurs)来自SuperMongo程序。我这样做的原因是因为这个程序我快进了石器时代，使用了这两个库。

我在interwebs上发现了一个LAPACK宏(ax_lapack.m4)，它似乎可以在我的系统上找到LAPACK库。我尝试将此.m4文件复制到ax_supermongo.m4，并更改必要的名称和目录。但是，我不是M4专家，所以我不知道这是不是在做我想做的事情。我不这么认为，因为如果您查看./configure的输出，它似乎没有找到sm_graphics文件( ax_supermongo.m4使用的标记supermongo例程到SM库的位置)：

在我的系统上，Supermongo库位于: /usr/local/misc/sm/sm2_4_36/lib/

关于如何让autoconf查看此目录，或者可能使用命令行变量传递此目录，有什么建议吗？

如果你需要更多的信息，请告诉我。

autoconf不会尝试为您查找这些库，但它生成的configure脚本会这样做。如果希望configure脚本在/usr/local/misc/sm/sm2_4_36/lib/中查找，所使用机制将取决于您的系统，但是为LDFLAGS=-L/usr/local/misc/sm/sm2_4_36/lib/形式的配置脚本提供参数是非常常见的。您可能还需要向CPPFLAGS添加一个类似的-I子句来查找头文件。
