If the former, then # each compilation step locks the pdb file for writing, which # is a bottleneck and object files from one target can not be # used in a different target. The latter seems to be the # sensible one (and what Unix does) but there is a catch. If # you try to use precompiled headers MSVC will error out # because both source and pch pdbs go in the same file and # they must be the same. # # This means: # # - pch files must be compiled anew for every object file (negating # the entire point of having them in the first place) # - when using pch, output must go to the target pdb # # Since both of these are broken in some way, use the one that # works for each target. This unfortunately means that you # can't combine pch and object extraction in a single target. # # PDB files also lead to filename collisions. A target foo.exe # has a corresponding foo.pdb. A shared library foo.dll _also_ # has pdb file called foo.pdb. So will a static library # foo.lib, which clobbers both foo.pdb _and_ the dll file's # export library called foo.lib (by default, currently we name # them libfoo.a to avoidt this issue). You can give the files # unique names such as foo_exe.pdb but VC also generates a # bunch of other files which take their names from the target # basename (i.e. "foo") and stomp on each other. # # CMake solves this problem by doing two things. First of all # static libraries do not generate pdb files at # all. Presumably you don't need them and VC is smart enough # to look up the original data when linking (speculation, not # tested). The second solution is that you can only have # target named "foo" as an exe, shared lib _or_ static # lib. This makes filename collisions not happen. The downside # is that you can't have an executable foo that uses a shared # library libfoo.so, which is a common idiom on Unix. # # If you feel that the above is completely wrong and all of # this is actually doable, please send patches. if target.has_pch(): tfilename = self.get_target_filename_abs(target) return compiler.get_compile_debugfile_args(tfilename) else: return compiler.get_compile_debugfile_args(objfile) def get_link_debugfile_args(self, linker, target, outname): return linker.get_link_debugfile_args(outname) def generate_single_compile(self, target, outfile, src, is_generated=False, header_deps=[], order_deps=[]): """ Compiles only C/C++ and ObjC/ObjC++ sources """ if(isinstance(src, str) and src.endswith('.h')): raise RuntimeError('Fug') if isinstance(src, RawFilename) and src.fname.endswith('.h'): raise RuntimeError('Fug') extra_orderdeps = [] compiler = self.get_compiler_for_source(src, target.is_cross) commands = [] # The first thing is implicit include directories: source, build and private. commands += compiler.get_include_args(self.get_target_private_dir(target), False) # Compiler args for compiling this target commands += compilers.get_base_compile_args(self.environment.coredata.base_options, compiler) # Add the root source and build directories as include dirs curdir = target.get_subdir() tmppath = os.path.normpath(os.path.join(self.build_to_src, curdir)) commands += compiler.get_include_args(tmppath, False) if curdir == '': curdir = '.' commands += compiler.get_include_args(curdir, False) # -I args work differently than other ones.
