dll - 配置脚本不启用 make 生成共享库

Question

这是关于编译 libjpeg v6b(如果相关的话)。

我运行 ./configure --prefix=/c/tmp/jpeg-6b-build --enable-shared --enable-static 就像安装文档说的那样，但 libtool 没有它。

checking dynamic linker characteristics... no
checking if libtool supports shared libraries... no
checking whether to build shared libraries... no
checking whether to build static libraries... yes

我想我需要这个共享库才能编译一些函数。 libjpeg 本身编译得很好，它生成的 .exe 可以工作，但我需要将源代码用于其他用途。由于某些原因，v6b 不会生成 .DLL，而 v9 会。

你应该尝试运行

./configure --help

并查看所有可用的配置标志，也许你拼错了一些或者你需要 --enable-dynamic或不同的东西。

对于配置输出，您也可以引用 config.log ，即在项目的(在您的情况下 - libjpeg 的)目录中，就在 configure 旁边文件。
