我正在使用autotools构建一个项目。我有configure.ac,makefile.am和autogen.sh。这一切都很好。我的Jenkins管道可以拾取并运行它。我的问题是makefile.am越来越长。最近我在我的项目中添加了一些第三方供应商代码。
这是当前makefile.am

我真的必须单独包括每个.c文件吗?为什么vendor/my_vendor/host/*/**不能工作?如何压缩makefile.am?
Autotools开发人员认为明确列出所有源文件是最佳实践。这避免了像测试或调试源之类的东西潜入到发行包中。
你不能使用**，因为这个语法是一个非标准的扩展，特别在shell中可用，比如bash和zsh，它不被标准POSIX globbing支持(这是它的glob扩展的用途)。
我认为在Makefile.am中使用简单的globbing(即*.c)会起作用，但当然你仍然需要使用每个目录。
再加一句:
你也可以让你的makefile更"整洁"把资料分成几个部分。例如，你可以输入:
MAIN_Application_SOURCES =
src/main.cpp
src/scheduler.c
src/thread_health.c
src/signal_handler.c
MAIN_Application_SOURCES +=
src/utilities/time_conversions.c
src/utilities/ring_buffer.c
src/utilities/logger.c
src/utilities/string_operations.c
MAIN_Application_SOURCES +=
src/config_parsing/file_operations.c
src/config_parsing/config_parser.c
MAIN_Application_SOURCES +=
src/comms/can.c
src/comms/can_ring_buffer.c
MAIN_Application_SOURCES +=
vendor/my_vendor/production/source/lib/FFT/FFT.c
vendor/my_vendor/production/source/PROD_lib.c
vendor/my_vendor/host/source/HLB_helper.c
vendor/my_vendor/host/source/HLB_nscm.c
vendor/my_vendor/host/source/HLB_apcm.c
vendor/my_vendor/host/source/HLB_fwload.c
vendor/my_vendor/host/source/HLB_host.c
vendor/my_vendor/host/source/HLB_noise_floor.c
vendor/my_vendor/host/source/lib/mem_pool/src/mem_pool.c
vendor/my_vendor/host/source/lib/comm_mgr/src/comm_mgr_lib.c
vendor/my_vendor/host/source/lib/osal/src/osal.c
vendor/my_vendor/host/source/HLB_legacy_commands.c
vendor/my_vendor/host/source/HLB_protocol.c
之类的，或者你甚至可以使用其他变量，然后把它们加在一起。也许这有助于提高可读性。
