未能构建libprocess,autotools出现问题[重复]

我从下载libprocess https://github.com/3rdparty/libprocess ,然后按照构建命令运行:

./bootstrap

会有一条警告说:

Makefile.am:97: warning: source file 'src/tests/time_tests.cpp' is in a subdirectory,
Makefile.am:97: but option 'subdir-objects' is disabled

所以我在配置中添加了“subdir对象”。ac文件:

AM_INIT_AUTOMAKE([-Wall -Werror -Wno-portability foreign subdir-objects])

现在./bootstrap运行顺利,但当我在mkdir“build”目录下运行“../configure;make”时,它失败了,原因是:

Making all in 3rdparty
Makefile:879: gmock-1.6.0/src/.deps/libgmock_la-gmock-all.Plo: No such file or directory
Makefile:880: gmock-1.6.0/gtest/src/.deps/libgmock_la-gtest-all.Plo: No such file or directory
Makefile:881: ry-http-parser-1c3624a/.deps/libry_http_parser_la-http_parser.Plo: No such file or directory
Makefile:882: stout/tests/.deps/stout_tests-bytes_tests.Po: No such file or directory
Makefile:883: stout/tests/.deps/stout_tests-duration_tests.Po: No such file or directory

我发现,在build/3rdparty目录中,有以下目录:

$(GMOCK)
$(GTEST)
$(RY_HTTP_PARSER)
$(STOUT)

所以我认为问题是$(GMOCK)应该在配置过程中转换为GMOCK-1.6.0,但它没有。

但我找不到修复这个bug的方法,谁能给我一些线索?
