我一直在安装 dvipng 软件包。由于我遇到即使安装后也找不到 libkpathsea 的问题，我尝试按照说明进行操作（http://www.nongnu.org/dvipng/dvipng_2.html#Build_002finstall）：
在某些计算机上，库将安装在不在链接器搜索路径中的目录中。这将在运行“./configure”时生成错误，表明它找不到 libgd 或 libkpathsea（很可能）。然后，您需要指定相应库的目标文件的路径。它们通常被称为“libgd.a”或“libgd.so”。如果它们位于例如“/usr/local/lib”中，则执行
./configure LDFLAGS=-L/usr/local/lib如果该库可作为共享对象文件（“.so”）使用，则运行时链接器可能还需要被告知在哪里可以找到该库，然后使用
./configure LDFLAGS='-L/usr/local/lib -R/usr/local/lib'
这正是我的情况：我已经安装了 Latex 的库，并且在我的 lib 文件夹中有“libgd.a”或“libgd.so”。然而，当我尝试运行他提到的代码时，据报道：
checking for C compiler default output file name... configure: error: C compiler cannot create executables
我的 config.log 是：
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by dvipng configure 1.9, which was
generated by GNU Autoconf 2.60. Invocation command line was
$ ./configure LDFLAGS=-L/usr/local/lib -R/usr/local/lib

有人可以帮我吗？
答案1
忽略这-R部分，GCC 没有这个选项；另外，你不需要告诉./configure看/usr/local/lib，所以
./configure
应该管用。
