如何在Automake和libtool-using项目中构建* .so模块？(How to build *.so module in Automake and a libtool-using project?)

 我有和其他人一样的问题： 
 
 
 
 我有一个*.la文件，由libtool在Automake项目（例如module.la ）中生成， 
 
 
 但我需要*.so才能将它用于dlopen() （例如module.so ）。 
 
 
 但是：项目使用--disable-shared进行配置和构建，以确保创建的主二进制文件是一个大的静态链接程序，例如main.x （更易于部署和调试）。 因此*.so文件不会被创建。 
 
 程序main.x是一个巨大的类似框架的应用程序，它能够通过dlopen()加载扩展（模块dlopen() - 尽管它是静态链接的。 
 
 当我手动构建module.so时，这工作正常。 但是把这个工作放在Makefile.am对我来说似乎是不可能的。 是的，我可以写lib_LTLIBRARIES ，但是用我的标准--disable-shared我没有得到*.so文件。 
 
lib_LTLIBRARIES = module.la
module_so_SOURCES = module.cpp
 
 文件module.la被创建，其中dlopen()拒绝加载（当然）。 
 
 我试图将规则放入Makefile.am ，手动构建它，并且工作正常： 
 
# Makefile.am (yes, .am)
all: mm_cpp_logger.so

SUFFIXES = .so

%.so: %.cpp
    $(CXX) $(CXXFLAGS) -fPIC -fpic -c -I $(top_srcdir)/include -o $@  $<

%.so: %.o
    $(CXX) $(LDFLAGS) -shared -fPIC -fpic -o $@  $<
 
 但这只能是一种解决方法。 我没有获得像依赖检查和安装等所有不错的自动功能。 
 
 我如何构建module.so ，并在Makefile.am使用--disable-shared （或者具有相同的效果）构建主程序？ 
 
 
 
 我可以使用特殊的automake规则将*.la文件处理为*.so文件吗？ 
 
 
 我可以在任何情况下调整lib_LTLIBRARIES进程来创建*.so文件吗？ 
 

I have the same problem as others have:
 
 
 
I have a *.la file generated by libtool in an Automake project (e.g. module.la),
 
 
but I need the *.so of it to use it for dlopen() (eg. module.so).
 
 
But: project is configured and built with --disable-shared to make sure the created main binary is one big statically linked program, e.g. main.x (easier for deployment and debugging). Thus *.so files are not created.
 
The program main.x is a huge framework-like application which is capable of loading extensions (modules) via dlopen() -- despite it being linked statically.
 
This works fine when I build module.so by hand. But putting this to work in Makefile.am seems impossible to me. Yes, I can write lib_LTLIBRARIES, but with my standard --disable-shared I do not get a *.so file.
 
lib_LTLIBRARIES = module.la
module_so_SOURCES = module.cpp
 
The file module.la is created, which dlopen() refuses to load (of course).
 
I tried to put rules into Makefile.am building it manually and that works:
 
# Makefile.am (yes, .am)
all: mm_cpp_logger.so

SUFFIXES = .so

%.so: %.cpp
    $(CXX) $(CXXFLAGS) -fPIC -fpic -c -I $(top_srcdir)/include -o $@  $<

%.so: %.o
    $(CXX) $(LDFLAGS) -shared -fPIC -fpic -o $@  $<
 
But this can only be a workaround. I do not get all the nice auto-features like dependency-checking and installation.
 
How can I build module.so with still building the main program with --disable-shared (or with the same effect) in the Makefile.am-way?
 
 
 
can I postprocess *.la files to *.so files with a special automake rule?
 
 
can I tweak the lib_LTLIBRARIES process to create *.so files in any case?
