MINGW build suggestions..

[d3vv]

I found out this repo more friendly for windows builds.. It is about:
@sergeevabc #2

I suggest to use cygwin-patch first:

https://github.com/fd00/yacp/blob/master/dieharder/dieharder-3.31.1-1bl2.src.patch

Then we have an error like:

dab_dct.c: In function 'fDCT2':
dab_dct.c:251:41: error: 'M_PI' undeclared (first use in this function)
  251 |   output[i] += (double) input[j] * cos((M_PI / len) * (0.5 + j) * i);
      |                                         ^~~~
dab_dct.c:251:41: note: each undeclared identifier is reported only once for each function it appears in
dab_dct.c: In function 'iDCT2':
dab_dct.c:274:27: error: 'M_PI' undeclared (first use in this function)
  274 |   sum += input[j] * cos(((M_PI * j) / len) * (0.5 + i));
      |                           ^~~~
make[1]: *** [Makefile:780: libdieharder_la-dab_dct.lo] Error 1
make[1]: Leaving directory '/home/dew/repos/dieharder/libdieharder'
make: *** [Makefile:927: libwulf.time] Error 2

Solution for libdieharder/dab_dct.c:

$ diff libdieharder/dab_dct.c libdieharder/dab_dct.c.OLD
39,42d38
< #ifndef M_PI
<     #define M_PI 3.14159265358979323846
< #endif
<

Next too much errors like:

dab_filltree.c: In function 'insert':
dab_filltree.c:109:2: error: unknown type name 'uint'; did you mean 'int'?
  109 |  uint d = (startVal + 1) / 2;
      |  ^~~~
      |  int
dab_filltree.c:110:2: error: unknown type name 'uint'; did you mean 'int'?
  110 |  uint i = startVal;
      |  ^~~~
      |  int
make[1]: *** [Makefile:787: libdieharder_la-dab_filltree.lo] Error 1
make[1]: Leaving directory '/home/dew/repos/dieharder/libdieharder'
make: *** [Makefile:927: libwulf.time] Error 2

Solution:

$ diff include/dieharder/libdieharder.h include/dieharder/libdieharder.h.OLD
1,7d0
< #ifdef __MINGW32__
< #ifndef Types_H
< #define Types_H
< typedef unsigned int            uint;
< #endif
< #endif
<

Then we have a warning:

libtool: warning: undefined symbols not allowed in x86_64-w64-mingw32 shared libraries; building static only

Solution: add "-no-undefined" flag:

$ diff libdieharder/Makefile.am libdieharder/Makefile.am.OLD
22,23c22,23
< libdieharder_la_LDFLAGS = -no-undefined -version-number @DIEHARDER_LT_VERSION@
< libdieharder_la_CFLAGS = -std=gnu99 -Wall -pedantic
---
> libdieharder_la_LDFLAGS = -version-number @DIEHARDER_LT_VERSION@
> libdieharder_la_CFLAGS = -std=c99 -Wall -pedantic

I have used mingw64 from msys2 and clang (due to some bugs from gcc):

 ./autogen.sh
CC="clang" CFLAGS="-O3 -pipe" LDFLAGS="-static -Wl,-Bstatic" ./configure
make
strip dieharder/dieharder.exe

Static binary for Windows 64-bit attached below
dieharder.zip

@rurban Could it possible add patches to ur repo?

[rurban]

Appveyor or GH Actions could be used to provide windows binaries for the unfortunate

[d3vv]

@rurban But gcc 10.x failed to build libdieharder cause code for shared object against dynamic link library. Moreover need to add LDFLAGS="-static -Wl,-Bstatic" for mingw-platform. And it wil be nice to fix warnings below:

$ ./autogen.sh
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

Fix warnings:

Also we have one more warning for configure:

checking whether build environment is sane... yes
/home/dew/repos/dieharder/missing: Unknown `--is-lightweight' option
Try `/home/dew/repos/dieharder/missing --help' for more information
configure: WARNING: 'missing' script is too old or missing

Solution:

$ autoreconf -fi
libtoolize: putting auxiliary files in '.'.
libtoolize: copying file './ltmain.sh'
libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, 'm4'.
libtoolize: copying file 'm4/libtool.m4'
libtoolize: copying file 'm4/ltoptions.m4'
libtoolize: copying file 'm4/ltsugar.m4'
libtoolize: copying file 'm4/ltversion.m4'
libtoolize: copying file 'm4/lt~obsolete.m4'
configure.ac:34: installing './compile'
configure.ac:14: installing './missing'
dieharder/Makefile.am: installing './depcomp'

[d3vv]

Consider add autoreconf -fi into autogen.sh as well

[d3vv]

All together after patch-solutions via MSYS2 (Mingw64, GSL, Clang, Linker tools for LLVM):

$ cat build-mingw.sh
#!/bin/sh

./autogen.sh
CC="clang" CFLAGS="-O3 -pipe -fuse-ld=lld -ffunction-sections" LDFLAGS="-static -s -Wl,-Bstatic -Wl,--gc-sections" ./configure
make

Finally optimized

DIEHARDER FOR WINDOWS

dieharder.zip

@rurban Would You like to apply solutions above for your repo and open issue section?
In this case I can:

• test sources for Windows 7, Gentoo Linux and macOS Catalina;
• fix sources and apply for modern compilers;

[rurban]

OK, will do.
I'll also add appyeyor smokes for windows to provide binaries for all master commits

[rurban]

https://github.com/rurban/dieharder/releases contains now windows binaries for all master commits.
mingw and cygwin smokes for 32 and 64bit.
