I'm exploring the xcode support (on 10.6.6 OS X). Interesting notes so far:

• It won't compile with PCH enabled because there's a relative path issue - it can't find precompiled.h so the build fails
  
• Running update-workspaces-new.sh using the --without-pch option allows the build to continue
  
• source/lib/sysdep/arch/x86_64/topology.cpp fails to compile due to std::bitset not being defined. So I included <bitset> instead of <set> and it compiled, hopefully this works on other platforms?
  
• There's a lot of annoying Boost warnings like these, but which don't seem to affect the build:
  
  

  /opt/local/include/boost/mpl/has_xxx.hpp:344:0 /opt/local/include/boost/mpl/has_xxx.hpp:344:9: warning: "BOOST_MPL_HAS_XXX_NO_EXPLICIT_TEST_FUNCTION" is not defined

  /opt/local/include/boost/detail/container_fwd.hpp:71:0 /opt/local/include/boost/detail/container_fwd.hpp:71:9: warning: "BOOST_CLANG" is not defined

• Next I ran into a few problems:
  
  • I get a fatal error from nasm about unrecognized output format 'macho64', which is strange but led me to this ticket (I'm running the 64-bit kernel)

  • I tried upgrading nasm through MacPorts but already have the latest port (2.09.09)
    
  • In the process I upgraded all outdated ports. Boost was upgraded from @1.46.1_0 to @1.47.0_0 but this seems to have broken the build badly (many errors about random::rand48 being re-declared), so I had to revert back to 1.46. Safe to say, 1.47 should not be used until that's fixed. If you upgrade by accident, try "sudo port activate boost @1.46.1_0" or install it as needed.
• And finally a linker error due to the above error in liblowlevel (but why would the build process continue?)

source/lib/sysdep/arch/x86_64/topology.cpp fails to compile due to std::bitset not being defined. So I included <bitset> instead of <set> and it compiled, hopefully

hm, Philip had already fixed this one by adding <bitset>.
I think <set> is no longer needed (there's certainly no std::set in there), so replacing <set> should be fine.
Unfortunately I can't help with the nasm problem, except to indicate that we're really close to stomping out the last of the asm.

I've been discussing this with Philip and the best guess at something GCC-palatable is:

#define __cpuid(level, index, a, b, c, d)                      \
  __asm__ ("cpuid\n\t"                                  \
           : "=a" (a), "=b" (B), "=c" ©, "=d" (d)     \
           : "0" (level), "2" (index))

This would be inserted into static void cpuid #if !HAVE_CPUIDEX, replacing the two asm calls.
level is the initial value of regs->eax, index is regs->ecx, and a,b,c,d are the output values that are to be written to regs->eax,ebx etc.
Would you like to give that a try?
If that compiles despite GCC -fPIC, then we're golden.

Well this is funny, I ran nasm manually on the command line and then tried building again and it succeeded (using the environment vars from the above error message). I wonder if there's something it doesn't like about the format of that string, maybe extra whitespace somewhere? Or more likely something in the environment that breaks it but what...

hm, Philip had already fixed this one by adding <bitset>.
I think <set> is no longer needed (there's certainly no std::set in there), so replacing <set> should be fine.

Ah you're right, but somehow that wasn't updated even though I have the latest revision O.o

Unfortunately I can't help with the nasm problem, except to indicate that we're really close to stomping out the last of the asm.

I've been discussing this with Philip and the best guess at something GCC-palatable is:

#define __cpuid(level, index, a, b, c, d)                      \
  __asm__ ("cpuid\n\t"                                  \
           : "=a" (a), "=b" (B), "=c" ©, "=d" (d)     \
           : "0" (level), "2" (index))

This would be inserted into static void cpuid #if !HAVE_CPUIDEX, replacing the two asm calls.
level is the initial value of regs->eax, index is regs->ecx, and a,b,c,d are the output values that are to be written to regs->eax,ebx etc.
Would you like to give that a try?
If that compiles despite GCC -fPIC, then we're golden.

Umm I'll need a while to digest this, but sure I'll try it

[historic_bruno]

Like this? If so, it did compile.

static void cpuid(x86_x64_CpuidRegs* regs)
{
#if HAVE_CPUIDEX
	cassert(sizeof(regs->eax) == sizeof(int));
	cassert(sizeof(*regs) == 4*sizeof(int));
	__cpuidex((int*)regs, regs->eax, regs->ecx);
#else
	#define __cpuid(level, index, a, b, c, d)                      \
	__asm__ ("cpuid\n\t"                                  \
			: "=a" (a), "=b" (B), "=c" ©, "=d" (d)     \
			: "0" (level), "2" (index))
#endif
}

The nasm-problem is a known issue and should be documented in the build instructions.
XCode ships with an older version of nasm which does not support the macho64 flag.
I've solved it on my system by replacing the nasm-binary of Xcode with a symbolic link to the newer one installed via macports.
I'm not sure if that's a good solution though.

EDIT:
I can't reproduce ticket # 903.
When I change something, it rebuilds the file. Did somebody already fix it?
Ah I see, It's only when running make scriptinterface. It rebuilds properly if you just run make.

We still need to add the actual macro invocation.
I'd suggest replacing the HAVE_CPUIDEX block with

#if defined(_MSC_FULL_VER) && _MSC_FULL_VER >= 150030729
// VC10+ and VC9 SP1: __cpuidex is already available
#elif GCC_VERSION
# define __cpuidex(regsArray, level, index)\
	__asm__ ("cpuid\n\t"\
	: "=a" (regsArray[0]), "=b" (regsArray[1]), "=c" (regsArray[2]), "=d" (regsArray[3])\
	: "0" (level), "2" (index))
#else
# error "compiler not supported"
#endif

Now cpuid() can just invoke __cpuidex without the need for any additional #if faff.
Does that work? *drumroll*

If I add a #error then run "make -k", it only recompiles (and fails for) mocks_*.cpp and status.cpp, it doesn't try rebuilding the .gch files or anything that depends on them (which it should).

Yes I've found the problem and I'm fixing it.

EDIT:
A patch is attached.
Please test it because I didn't have much time for tests.
It fixes ticket #903 and adds a command to clean-workspaces.sh for cleaning the premake4 environment.
For testing don't forget to run clean-workspaces.sh.

Question: Why do you even have a precompiled.cpp file? Shouldn't precompiled.h be sufficient?

I'm exploring the xcode support (on 10.6.6 OS X). Interesting notes so far:
...

• It won't compile with PCH enabled because there's a relative path issue - it can't find precompiled.h so the build fails

...

Changing the type of pchheader from "string" to "path" in api.lua fixes the problem.
I'm wondering why premake uses "path" for pchsource and "string" for pchheader.

I'm going to integrate this change into the patch from the last post and add it as an attachment to this post.

EDIT: Done, the new patch is up.

I think precompiled.cpp is needed when compiling with MSVC (since that's what generates the PCH file), but not needed with GCC (since the PCH is generated directly from the .h), so preferably the .cpp should be ignored when using GCC.

Well then my patch probably won't work on Windows.
Changing pchheader from string to path also made some problems on linux.
It looks like there's more testing and more work required...

Honestly, I find it quite a success that the game could be compiled successfully in XCode with just those two changes: build without PCH and manually run nasm!

That makes sense because the 64-bit OS X kernel is fairly new, surely they have fixed this for XCode 4? I could buy it from the App Store and see what fun awaits... I wouldn't call replacing XCode's binaries a good solution, maybe there's some setting or path variable we could override to force the newer MacPort nasm, assuming we still need it

Would be interesting to know. It only cost about 5$ if I remember correctly.
I would have done it if I had a "real" mac .


Ok I hope this is the last and successful try, version 3 of the patch.
It's quickly tested on Linux, Mac and Windows... if I wasn't too tired and made mistakes .
Further testing appreciated!

Tested your patch on OS X, both gcc and xcode3 projects are working with PCH now That leaves the xcode3 test project, which fails to build:

/Users/ben/0ad/build/workspaces/xcode3/obj/test_Release/test.build/Script-9607AE1010C857E500CD1376.sh: line 58: ../../build/bin/cxxtestgen.pl: No such file or directory

Great news, congratulations and thanks, Philip, for the assist!
The patch looks good. Feel free to commit, as far as I'm concerned.

Looks good except for the CPU frequency. Intel CPUs mention their
intended clock rate in the brand string, but it'd be nice to measure the
actual frequency (to detect over/underclocking) at runtime.
We actually have code to do that, it's just not being called.
I intend to fix that later today.

Thank you for testing.
It seems to be a similar problem as the relative path issue with precompiled headers.
The directory structure was changed a little bit during the integration into svn (premake4.lua went up one level).
That seems to be the reason why we get problems with parts of the code that don't handle paths correctly.
I don't know if I have time to fix this one because I'm preparing for departure this evening. I'm going to be on holyday the next three weeks.

Yves, on 20 July 2011 - 09:00 AM, said:

Yeah, I thought it was better to keep it where the old premake.lua was, and to keep the premake4/ directory a clean copy of the Premake 4 sources rather than mixing in our own files.

[Ykkrosh]

Clang says

precompiled.h
clang: warning: treating 'c-header' input as 'c++-header' when in C++ mode, this behavior is deprecated

which I think means it wants "-x c++-header" on the command-line when compiling the .h file. (Our old Premake PCH modifications did that.)

[historic_bruno]

OK, here's a patch (for SVN trunk) that fixes the XCode test project's shell script. VS and XCode need the same path adjustment so I combined the two.
