I have to use env['CC']='g++' inside SConstruct to force the use of g++.
Notice that gcc can figure out by itself that it is compiling a C++ source. Quoting the gcc man page: C++ source files conventionally use one of the suffixes .C, .cc, .cpp, .CPP, .c++, .cp, or .cxx; C++ header files often use .hh or .H; and preprocessed C++ files use the suffix .ii. GCC recognizes files with these names and compiles them as C++ programs even if you call the com- piler the same way as for compiling C programs (usually with the name gcc). However, I don't know if there is a problem with SCons itself thinking a .C file is C (rather than C++) source file. And then I don't know why gcc can figure out that .c is different than .C and scons can't do the same... I attach here a log of the configuration step. It is currently compiling. Notice that Aiksaurus doesn't seem to have been tested for and that the client subdir in src is ignored. On Cygwin, lyxclient works. -- Enrico
