It is not only shorter than `not meson.is_cross_build() or meson.has_exe_wrapper()` but also handle the case of cross compiling to a compatible arch such as building for i386 on an amd64. |

The files asnprintf.c printf-args.c printf-args.h printf-parse.c printf-parse.h vasnprintf.c vasnprintf.h are taken from the vasnprintf module of the GNUlib package, which can be found at: http://www.gnu.org/software/gnulib/ All files have been modified to include g-gnulib.h. vasnprintf.c has also been modified to include support for long long printing if the system printf doesn't. This code is protected by #ifndef HAVE_LONG_LONG_FORMAT. Code has been added to printf-args.[ch], printf-parse.c and vasnprintf.c to support printing of __int64 values with the I64 format modifier. This is protected by #ifdef HAVE_INT64_AND_I64. The files printf.h printf.c g-gnulib.h have been written by me. printf.[hc] contain implementations of the remaining functions in the printf family based on vasnprintf. g-gnulib.h is included by all source files in order to move all exported functions to the _g_gnulib namespace, replace malloc by g_malloc and make sure that snprintf is only used if it implements C99 return value semantics. Matthias Clasen November 1, 2003 To update: * Create an empty directory, put a configure.ac file into it. * Run gnulib-tool --lgpl=2 --import --lib=libgnu --source-base=lib \ --m4-base=m4 --doc-base=doc --tests-base=tests --aux-dir=. \ --no-conditional-dependencies --no-libtool --macro-prefix=gl \ isnand-nolibm isnanf-nolibm isnanl-nolibm printf-frexpl \ signbit vasnprintf * Then pick out the files that are already in glib/gnulib subdirectory (the rest of the files are not needed): asnprintf.c c++defs.h float+.h fpucw.h gnulib_math.h.in (rename from math.in.h) isnan.c isnand.c isnand-nolibm.h isnanf.c isnanf-nolibm.h isnanl.c isnanl-nolibm.h printf-args.c printf-args.h printf-frexp.c printf-frexp.h printf-frexpl.c printf-frexpl.h printf-parse.c printf-parse.h signbitd.c signbitf.c signbitl.c vasnprintf.c vasnprintf.h verify.h xsize.h * Then look at the glib-gnulib.patch and re-introduce custom glib changes contained in that patch. * If gnulib_math.h.in got some new @variables@, these will have to be somehow set in meson.build, otherwise meson would warn about them at configure stage LRN June 06, 2018
