GNU Autotools:无需版本信息即可重建 [英] GNU Autotools: rebuild without version info

问题描述

我需要构建一个配置有自动工具的库.通常的configure && make && make install步骤生成版本化的共享库，例如libfoo.so.x.x是否可以修改configure.ac或Makefile.am(当然还要跟上autoreconf)，以便构建未版本化的lib.

谢谢！

解决方案

是的，假设该库是使用libtool构建的，则可以通过在库的LDFLAGS中添加-avoid-version标志来删除版本信息. >

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.之后，您将重新生成并重新运行配置(autoreconf -vfi&& ./configure)并重新生成.

仅删除-version-info ...是不够的，因为libtool随后将生成版本信息为0.0.0的库.

有关更多信息，请参见libtool手册: http://www.gnu.org/software/libtool/manual/html_node/Link-mode.html

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.

Thank you!

解决方案

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.

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.

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