Build errors in windows 10 x64 about fatty

[juho-p]

There's something wrong with your standard C++ library headers, which is very weird. Looks similar to #7

Try reinstalling g++ (I don't know how this works in babun). It might help.

I stumbled upon fatty today and I really wanted to have it. So I spent around 6 hours to make it work.

And here is the solution

1. Install Babun regularly, make sure that commands in the babun shell are actually served from the local babun cygwin (I just deleted all the rest since I just need one cygwin instance)
2. Download Cygwin x86 installer
3. Install the following packages at version 5.3.0-3: gcc-core gcc-g++ libquadmath0
4. Change src/Makefile according to my PR see file changes
5. Run make
6. Put %HOME%\.babun\cygwin\bin\ in your PATH variable (I recommend this free tool)
7. Enjoy src/fatty.exe

I put the compiled .exe file here, in case it doesn't work.

@tobiasmuehl nice work!

It seems newer versions of gcc failed to compile fatty without _GNU_SOURCE. I only noticed this now when I updated my Cygwin packages (didn't try that when this issue opened, my bad...), though I did have different compilation problem. This wasn't Babun specific problem.

@theVDude could you try again if it works now? I'm not sure if this change helps you or not, try it out.

FYI, I'm running this on the x64 version of Windows 10 and also not able to compile with our the "GNU_SOURCE" option inside src/Makefile.

Each time I get:

[ryanerwin]

I've run:
pact update gcc-core gcc-g++ make w32api-headers git libquadmath0

As @tobiasmuehl describes, I've made sure gcc and g++ are both at version 5.3:

`➜ % gcc --version 23:04
gcc (GCC) 5.3.0

➜ % g++ --version 23:04
g++ (GCC) 5.3.0`

Yet this way I get a bunch of errors for functions that aren't defined in cstdlib (::at_quick_exit) and in c++/cmath (achshl, asinhl, atanhl, cbrtl, copysignl, erfl, exp2l, expm1l, fdiml, fmal, fmaxl, fminl, ilogbl, lgammal, llroundl, log1pl, nanl, nearbyintl, nextafterl,nexttoward, nexttowardf, remainderl, remquol, roundl, scalblnl, scalbnl, tgammal, truncl)

Ending with:

/usr/lib/gcc/i686-pc-cygwin/5.3.0/include/c++/cmath:1205:11: error: ‘::truncl’ has not been declared using ::truncl; ^ Makefile:45: recipe for target 'build/childxx.o' failed make[1]: *** [build/childxx.o] Error 1 make[1]: Leaving directory '/cygdrive/c/Users/ryan/fatty/src' Makefile:2: recipe for target 'exe' failed make: *** [exe] Error 2

I also tried downloading the attached binary, but Windows warns that the binary is infected with "Spursinst.A!cl" trojan:

[tobiasmuehl]

I had those issues as well, but don't recall as to how I solved them. The virus warning is a false positive (well, I assume the source code isn't harmful). I uploaded it to VirusTotal here

I also ran automake before running make but it only resulted in errors, so I don't think it affected anything.

Have you run the Cygwin installer to check the version of libquadmath0? It is the package that contains the math library for the compiler

[ryanerwin]

I ran: pact update gcc-core gcc-g++ libquadmath0 and modified src/Makefile to add CPPFLAGS := -DTARGET=$(TARGET) -D_GNU_SOURCE but I'm still getting compilation errors.

/usr/lib/gcc/i686-pc-cygwin/5.3.0/include/c++/cstdlib:126:11: error: ‘::at_quick_exit’ has not been declared using ::at_quick_exit;

Any idea how to get this to compile?

[juho-p]

This is really weird issue.

@ryanerwin When I look your error message (at_quick_exit missing), it says your c++ standard library header can't see function called at_quick_exit, but that function just has to be there, since it's defined by standard library itself.

I recently updated cygwin to the latest version and recompiled fatty without any problem, so there shouldn't be any issue with fatty anymore (I hope!).

Maybe this is a Windows issue that causes some files not to update? Try uninstalling g++ and gcc, verify that there is no /usr/lib/gcc directory, then install it again and try compiling fatty again. This is just guessing anyway, so it probably doesn't do any good.

[theVDude]

Wow, apparently my github email needs update. Still not compiling in babun for me, but I'm going to try a fresh cygwin install in a moment.

Works fine in cygwin, so this is most likely a weird babun bug. I guess I'll have to make a note of it over there!

[theVDude]

Alright, so running the cygwin installer to install packages instead of pact totally worked. I'm going to have to assume there's something wrong with pact grabbing/updating dependencies.

Solution is as tobias said, use the cygwin installer and point it to your babun cygwin installation, and tell it to reinstall the packages.
