在automake / gcc中混合使用C ++ 98和C ++ 11源代码

Question

I have a list of cpp files in project which is built using automake tools.

Some of them are written using pre-C++11 standard (ie C++98) and they cannot compile with c++11 flag of gcc (-std=c++11).

Latest cpp files are using C++11 standard and they need -std=c++11 flag in compile.

Can I define in Automake two lists of cpp source files and give different compilation flags?

Answer 1

This is ripped directly from Setting per-file flags with automake

You may bundle your c++11 code into a lib and provide different flags for this code subset in Makefile.am

bin_PROGRAMS        = test 
test_SOURCES        = main.cpp 
test_LDADD          = c11code.la 
noinst_LTLIBRARIES  = c11code.la  
c11code_la_SOURCES  = cxx1_1.cpp cxx1_2.cpp cxx1_3.cpp 
c11code_la_CXXFLAGS = $(CXXFLAGS) -std=c++11
