I am trying to cross-compile this project to MinGW.

The project uses autotools as the build system, and depends on libcurl, CUnit, Jansson and some gnulib modules.

I have all the dependancies compiled for x86_64-w64-mingw32 and installed under /home/user/mingw64

I run:

$ gnulib-tool --update
$ autoreconf -fi
$ CURL_CFLAGS="-I/home/user/mingw64/usr/local/include" \
CURL_LIBS="-L/home/user/mingw64/usr/local/lib -lcurl" \
JANSSON_CFLAGS="-I/home/user/mingw64/usr/local/include" \
JANSSON_LIBS="-L/home/user/mingw64/usr/local/lib -ljansson" \
CUNIT_CFLAGS="-I/home/user/mingw64/usr/local/include" \
CUNIT_LIBS="-L/home/user/mingw64/usr/local/lib -lcunit" \
./configure --host=x86_64-w64-mingw32
$ make

And I get this error:

make  all-recursive
make[1]: Entering directory '/home/user/projects/shill'
Making all in po
make[2]: Entering directory '/home/user/projects/shill/po'
make[2]: Nothing to be done for 'all'.
make[2]: Leaving directory '/home/user/projects/shill/po'
Making all in lib
make[2]: Entering directory '/home/user/projects/shill/lib'
make[2]: *** No rule to make target 'lib/errno.h', needed by 'all'.  Stop.
make[2]: Leaving directory '/home/user/projects/shill/lib'
Makefile:1897: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/user/projects/shill'
Makefile:1429: recipe for target 'all' failed
make: *** [all] Error 2

errno.h is part of the gnulib modules. So I think that the problem comes from this section in the Makefile.am:

# Find gnulib headers.
ACLOCAL_AMFLAGS = -I m4

AM_CPPFLAGS = \
  -DLOCALEDIR='"$(localedir)"' \
  -Ilib -I$(top_srcdir)/lib \
  -Isrc -I$(top_srcdir)/src \

But I can't figure out the solution. I followed exactly the instructions described in the gnulib manual.

我设法找到了解决此问题的方法。显然autotools没有我想象的那么容易。

  1. 我不得不重新生成gnulib模块，这次指定 --makefile-name参数。IE。

    $ gnulib-tool ... --makefile-name=gnulib.mk ...

  2. 我lib/Makefile从自动生成的文件中删除了configure.ac. 所以而不是：

    dnl Put automake generated files results here
AC_CONFIG_FILES([Makefile
       po/Makefile.in
       lib/Makefile])

    我现在有：

    dnl Put automake generated files results here
AC_CONFIG_FILES([Makefile
           po/Makefile.in])

  3. 我删除lib了SUBDIRS. Makefile.amIE。代替：

    # Subdirectories to descend into.
SUBDIRS = po lib

    我有：

    # Subdirectories to descend into.
SUBDIRS = po

  4. lib我在名为以下内​​容的目录中创建了一个新文件local.mk：

    include lib/gnulib.mk

# Allow "make distdir" to succeed before "make all" has run.
dist-hook: $(noinst_LIBRARIES)
.PHONY: dist-hook

  5. 并将其包含在Makefile.am.

    include $(top_srcdir)/lib/local.mk

  6. 最后我不得不运行这个命令：

    $ ./build-aux/prefix-gnulib-mk --lib-name=libshill lib/gnulib.mk

就是这样。
