This seems like a problem that's really hard to google! Which is why I finally came here after so long. I was compiling the updated Half-Life SDK, and I get approx. 4000 lines of errors, all within default headers/
I tried reinstalling g++-multilib, being the primary dependency listed, but evidently it didn't help. I also tried any gcc packages I thought of, none of which worked.
Compiling under latest Ubuntu stable.

I solved it by manually replacing math.h. I'm not sure if this is advisable, only that it did in fact work in my case.

I am trying to build the apcupsd package under a newer version of MacOS and Xcode, but the configure script supplied with the current version of apcupsd breaks under Xcode 12.4 (though it worked under Xcode 11.2).
The error is gethostbyname_r is required. Now, configure tests for this function, and ordinarily it adapts to systems that do not provide it. On the newer Xcode version, however, configure just exits with an error. I THINK it has something to do with Apple making the -Werror setting mandatory. I've found that I can get a successful build by commenting out the broken test in configure, then running it and explicitly passing the flag that configure is supposed to set. But that's not very satisfactory.
Is there is a general way to pass an override to configure for the compiler? I tried setting -Wno-error in the CPPFLAGS and CFLAGS environment for configure, but the configtest program seems to ignore those. What seems to be going on is configure is seeing that gethostbyname_r doesn't exist and sets it to no but then later on still tests for it. I'm just wondering if there's a flag or something to get past this error, as it seems to me that whatever Apple did to break (or fix) Xcode after version 11.2 would have broken a lot of people's projects.
I am looking for a solution that does not involve modifying the program sources or the Autotools input files. The project manual is not helpful in this regard.
As an update: someone on the apcupsd list told me that this issue is fixed in a later version of Xcode. I have not tried that yet but when I do if that is what it proves out to be I'll post a followup

If you set the CFLAGS or CPPFLAGS variable in configure's environment, then not only should configure use those flags when it builds test programs, but it should also memorialize the variable so that you don't need to specify it again to make. Indeed, this ...
What seems to be going on is configure is seeing that
gethostbyname_r doesn't exist and sets it to no
... suggests that it is doing so in your case.
In that event, if it seems to test again later, or else to fail in some other way despite determining that the function is not present, then that suggests a flaw in the project's own autotooling.
I'm just wondering if there's a flag or something
to get past this error,
You have already tried the most likely candidate (CFLAGS). Alternatively, you might also be able work around the issue through use of a cache file. That's still hacky, but I think less so than modifying the configure script. I'm afraid I have no specific guidance on doing this.

It did. That does not imply that there is a quick or easy solution, though it would be good news if indeed Apple solved the issue in a later version of Xcode.
I am getting an error which I shouldn't get according to this and this.
My library does exist though (here is the proof):

How do I fix the error?
I refactored the code to get rid of the circular dependency and it's now compiling fine on all 3 platforms.
Its still weird though that only OSX Xcode didn't compile the code.
I've been struggling to get Auto Talent from Oli Larkin to compile for some time now. I'm pretty new to Xcode and that may be the issue, but either way I figured I'd see if anyone could help me. I'm trying to compile this in order to make a 64 bit version.
Starting from the top:
I've traced down a few things that I thought were the issues.
Noticed that wdl sdk was missing. Downloaded it from https://github.com/olilarkin/wdl-ol. Added the wdl folder outside of the src folder.
Got some warnings when starting up Xcode 5.0.2. Let Xcode fix them.
Realized that the /Developer/Examples folder doesn't exist in Mavericks. Found https://developer.apple.com/library/mac/samplecode/CoreAudioUtilityClasses/Introduction/Intro.html#//apple_ref/doc/uid/DTS40012328-Intro-DontLinkElementID_2, downloaded the sample code, linked to AUBase as I realized this path needed updating in the AU Build Settings (see screenshot).
iPlug.xcodeproj is in red. Not sure what to do about this. Any ideas? I'm assuming it's important.
Update: Based on the recent comments, I'm now getting somewhere. But, at the moment I'm getting the following errors. This has to do with not having a Lice SDK or something. Is this absolutely needed? If so, do you have the time to elaborate on this and where to get it? Thanks again for all of the help.
It looks like I'm getting another issue as well related to clang. Maybe related to Xcode - Command /Developer/usr/bin/clang failed with exit code 1, not sure.
Note: Before finally getting to the errors above, I had to...
Link CoreMIDI.framework "Frameworks and Libraries" -> "Linked Frameworks" -> App to /System/Library/Frameworks/CoreMIDI.framework.
Set compiler in the build settings to default compiler. Otherwise it said unsupported compiler and threw some warnings. Hopefully this didn't mess anything up.
Rename aeffect.h and aeffectx.h to aeffect.h and aeffectx.h from the VST3 SDK. You can find these files in public.sdk -> source -> vst2.x. Apparently 2.x isn't really supported anymore. After renaming them, I moved them to the VST_SDK folder in WDL as the readme instructed.
the source you have will not compile straight off with recent versions of WDL-OL, since lots has changed. The way to upgrade it is to strip out the pertinent source code (i.e. autotalent.h/cpp and the mayer fft stuff) and re-duplicate one of the template projects in WDL-OL and bring it in to the new folder.
I've done it for you:
https://github.com/olilarkin/autotalent
you can clone this repository into the IPlugExamples folder of WDL-OL, and provided you've put all the SDK files in place it should compile straight off.

There is a bug in RHEL5's gcc-4.3.2 with which we are stuck. As a work-around we have extracted the missing object and put it in an object file. Adding this object file to every link makes the problem go away.
While adding it directly to LDFLAGS seems like a good solution, this doesn't work since e.g. libtool cannot cope with non-la files in there.
A slightly more portable solution seems to be to directly patch the gcc spec to add this to every link. I came up with
*startfile:
+ %{shared-libgcc:%{O*:%{!O0:/PATH/TO/ostream-inst.o}}}
where ostream-inst.o is added to the list of startfiles used in the link when compiling a shared library with optimizations.
Trying to compile boost with this spec gives some errors though since its build directly sets some objects with ld's --startgroup/--endgroup.
How should I update that spec to cover that case as well, or even better, all cases?

If this help you, thats great.
I know this is not the answer you want to hear (since you specified otherwise in your question), but you are running into trouble here and are likely to run into more since your compiler is buggy. You should find a way of replacing it, since you'll find yourself writing even more work-around code the next time some obscure build system comes along. There's not only bjam out there.
Sorry I can't help you more. You might try simply writing a .lo file by hand (it's a two-liner, after all) and insert it into your LDFLAGS.
If it is a bug of GCC 4.3, did you try to build (by compiling from sources) and use a newer GCC. GCC 4.6.2 is coming right now. Did you consider using it?
I'm trying to port some very old fortran code to windows. I'd like to use mingw and f2c, which has no problem converting the code to usable C on OS X and Ubuntu. I used f2c.exe as distributed by netlib on a fresh install of mingw, and it translated the code fine. I have a "ported" version of libf2c that seems to still contain some unresolved references -- mostly file i/o routines (do_fio, f_open, s_wsfe, e_wsfe) and, peculiarly, one arithmetic routine (pow_dd). To resolve these issues, I tried to build libf2c from source, but ran into an issue during the make process. The make proceeds to dtime_.c, but then fails due to a dependency on sys/times.h, which is no longer a part of the mingw distro. There appears to be a struct defined in times.h that defines the size of a variable in dtime_.c, specifically t and t0 on lines 53 and 54 (error is "storage size of 't' isn't known"; same for t0).
The makefile was modified to use gcc, and make invoked with no other options passed.
Might anyone know of a workaround for this issue? I feel confident that once I have a properly compiled libf2c, I'll be able to link it with gcc and the code will work like it does on linux and os X.
FOLLOW-UP: I was able to build libf2c.a by commenting out the time related files in the makefile (my code does not contain any time related functions, so don't think it will matter). I copied it to a non-POSIX search directory as show in -print-search-dirs, specifically C:\MinGW\lib\gcc\mingw32\3.4.5. That seems to have fixed the issue on the unresolved references, although the need to eliminate the time files does concern me. While my code is now working, the original question stands -- how to handle makefiles that call for sys/times.h in mingw?
Are you sure the MinGW installation went correct? As far as I can tell the sys/times.h header is still there, in the package mingwrt-3.18-mingw32-dev.tar.gz. I'm not familiar with the gui installer, but perhaps you have to tick a box for the mingwrt dev component.
