Question

我正在使用autotool构建项目。基本上，该项目依赖于几个由autotool管理的第三方项目。

my_project/
my_project/3rd-party/

为了启用递归构建，我在configure.ac中添加了AC_CONFIG_SUBDIRS个宏：

AC_CONFIG_SUBDIRS([3rd-party/gtest-1.7.0])
AC_CONFIG_SUBDIRS([3rd-party/libstatgrab-0.91])
AC_CONFIG_SUBDIRS([3rd-party/leveldb-1.2.0])

这为我提供了递归构建，链接和清理的便利。但是，当我点击make install时，我不想安装所有这些第三方库，而是安装我自己的项目。反正我有没有摆脱这种特殊的递归？

Answer 1

如果您没有更改第3个pardy目录中的任何makefile（我甚至可以从主Makefile中执行，只需通过sed重命名目标，我认为您不能简单地删除此单个文件。 [脏黑客]）。

我猜你在第三方目录中调用内部配置，不是吗？如果是，您可以设置prefix（或data-prefix和exec-prefix) different. It may be a good idea in any case to create a第三方构建目录，并在那里构建第三方内容并更改安装前缀以使用此目录。< / p>

您没有要求它，但“解决方案”不同：从主makefile中删除第三方内容：

创建build_dep.sh
这可以下载和/或解压缩并配置和制作第三方内容
您的配置脚本（如果有的话）将检查这些脚本是否存在且是否正常工作，如果不存在：搜索系统目录。

这既解决了问题又允许使用库/工具（如果它们已经存在），并允许用户选择使用不同的版本，同时保持简单“你可以从主目录中获取所有这些并且不需要在你自己的“

上获得/构建依赖项

这并不是我所希望的，因为您还必须引入要在这些子树中使用的所有递归规则，但是它更接近了。

https://github.com/protocolbuffers/protobuf/blob/master/Makefile.am#L14

DIST_SUBDIRS = src conformance benchmarks third_party/googletest

# Build gmock before we build protobuf tests.  We don't add gmock to SUBDIRS
# because then "make check" would also build and run all of gmock's own tests,
# which takes a lot of time and is generally not useful to us.  Also, we don't
# want "make install" to recurse into gmock since we don't want to overwrite
# the installed version of gmock if there is one.
check-local:
    @echo "Making lib/libgmock.a lib/libgmock_main.a in gmock"
    @cd third_party/googletest/googletest && $(MAKE) $(AM_MAKEFLAGS) lib/libgtest.la lib/libgtest_main.la
    @cd third_party/googletest/googlemock && $(MAKE) $(AM_MAKEFLAGS) lib/libgmock.la lib/libgmock_main.la

# We would like to clean gmock when "make clean" is invoked.  But we have to
# be careful because clean-local is also invoked during "make distclean", but
# "make distclean" already recurses into gmock because it's listed among the
# DIST_SUBDIRS.  distclean will delete gmock/Makefile, so if we then try to
# cd to the directory again and "make clean" it will fail.  So, check that the
# Makefile exists before recursing.
clean-local:
    @if test -e third_party/googletest/Makefile; then \
      echo "Making clean in googletest"; \
      cd third_party/googletest && $(MAKE) $(AM_MAKEFLAGS) clean; \
    fi; \

避免递归make install
