GNU Autotools:在没有版本信息的情况下重建 [英] GNU Autotools: rebuild without version info

问题描述

我需要构建一个配置了 autotools 的库.通常的 configure &&制作&&make install 步骤生成版本化的共享库，类似于 libfoo.so.xx 是否可以修改 configure.ac 或 Makefile.am (当然还有 autoreconf )，以便 un-versioned lib 正在构建.

I need to build a lib that is configured with autotools. The usual configure && make && make install steps produce versioned shared lib, something like libfoo.so.x.x Is it possible to modify configure.ac or Makefile.am (and of course follow up with autoreconf ) so that un-versioned lib is build.

谢谢！

推荐答案

是的，假设库是用libtool构建的，可以通过添加-avoid-去掉版本信息version 标记到库的 LDFLAGS.

Yes, assuming that the library is built with libtool, you can remove the version information by adding the -avoid-version flag to the library's LDFLAGS.

例如，如果之前有libfoo_la_LDFLAGS = -version-info 1:0 您将其更改为 libfoo_la_LDFLAGS = -avoid-version.在此之后，您将重新生成并重新运行配置(autoreconf -vfi && ./configure)并重建.

For example, if before there was libfoo_la_LDFLAGS = -version-info 1:0 you would change it to libfoo_la_LDFLAGS = -avoid-version. After this, you'd regenerate and rerun configure (autoreconf -vfi && ./configure) and rebuild.

仅仅删除 -version-info ... 是不够的，因为 libtool 会生成一个版本信息为 0.0.0 的库.

Simply removing -version-info ... isn't sufficient, since libtool will then generate a library with version info 0.0.0.
