Re: [PATCH] Makefile fixes


After some off-list collaboration pretty much all of these changes have been applied now, although some are optional, e.g. by way of uncommenting the makefiles in places etc., in particular the static linking of libgcc etc. with the rationale being to maintain consistency with existing use.

In addition to these, static linked builds have been fixed with patches again from Daniel. The autostatic.c code was not being linked in.

Thanks.

Hello list,

I have a series of patches to contribute to pthreads-win32. This is the first one.

The attached patch, against the CVS source, does the following:

* Factors out the long lists of object and source files and object
  dependencies into common.mk (also attached as I can't do "cvs add"),
  which is now included by Bmakefile, GNUmakefile and Makefile. Variables
  are used to address the different object/resource file extensions.

I had noticed inconsistencies among the lists of objects/sources in each
of the three makefiles, so this approach will put an end to that.


* Fixes incorrect flags/objects used for building the static library

* Adjusts some compiler flags to facilitate building and testing the
  library

* Adds targets (all-tests, all-tests-cflags) to run the test suite on all
  of the library's build configurations, as these tend to have different
  codepaths that can significantly affect correctness

* "Make" syntax tweaks


Below is a more detailed walk-through of the changes:


++ Bmakefile

@ Factored out common variable definitions into common.mk

@ Use new RESOURCE_OBJS variable instead of a literal "version.res"

@ Factored out common dependencies into common.mk

Added end-of-file comment

++ GNUmakefile

@ I had trouble with test programs not running because DLLs for
libgcc/libstdc++/libgomp were not in the PATH, so these flags will link
them statically. (As MinGW is intended to produce "standalone" binaries,
this is what most people will probably want to do anyway)


@ MAKE is already set by the Make program

Factored out common variable definitions into common.mk

  As GNU Make supports "+=", use this to add RESOURCE_OBJS to the three
  object-file-list variables

@ Use $(MAKE), not "make" in the help text (e.g. MAKE could be "gmake")

New all-tests and all-tests-cflags targets (note that the latter is less
useful for MinGW compared to MSVC)


@ Static builds use small objects, not inlined/aggregate ones, so
  -DPTW32_BUILD_INLINED doesn't belong here

@ Likewise, static builds should use SMALL_STATIC_OBJS, not
  DLL_INLINED_OBJS

@ Factored out common dependencies into common.mk

Added end-of-file comment

++ Makefile

@ Factored out common variable definitions into common.mk

@ Removed "@" prefix from $(MAKE) invocations in the "all" target, as that
suppressed useful information (e.g. if you're redirecting terminal output
to a file for later review)


  New all-tests and all-tests-cflags targets (the latter covers both /MD
  and /MT configurations)

@ Static builds use small objects, not inlined/aggregate ones, so
  -DPTW32_BUILD_INLINED doesn't belong here

@ Fixed "install" rule for static builds (no *.dll file)

@ Added new RESOURCE_OBJS variable where needed

Static builds should use SMALL_STATIC_OBJS, not DLL_INLINED_OBJS

@ Factored out common dependencies into common.mk

Added end-of-file comment

++ tests/GNUmakefile

@ ECHO should be defined without the "@", as that is already given in the
  target recipes

Define TOUCH so that it uses ECHO

Define ECHO before TOUCH, for ordering

Don't define MAKE, because that should be set by the Make program itself

@ New variable XLIBS, to specify system/third-party libraries needed by
  some tests

  Only a couple of tests need -lws2_32 -lgomp; don't add these libs to
  everything if we can help it

  Use -static-libgcc and PTW32_FLAGS in CFLAGS, to avoid a dynamic
  dependency on libgcc and build with the same flags as the ptw32 library

@ Replaced "make" with $(MAKE), and a nice straight margin for the target
  descriptions

@ Only one test needs -fopenmp; don't add it to everything

Added -static-libstdc++ where useful

@ Normalized use of $(ECHO): prefixed by "@", and argument is double-quoted

Add -lws2_32, -fopenmp et al. only to the tests that need them, using GNU
Make magic


@ Show the compiler invocations directly

The -lsupc++ bit only caused errors on my system

XLIBS is used here

@ idem

++ tests/Makefile

@ Define TOUCH so that it uses ECHO

Define ECHO before TOUCH, for ordering

@ Use $(MAKE), not "nmake" in the help text

@ Use /nologo in the various $(MAKE) invocations to get rid of annoying
  Microsoft boilerplate

Show the compiler invocations directly
