將基於gnulib的項目交叉編譯到MinGW

Question

我想將此project交叉編譯到MinGW。

該項目使用autotools作爲構建系統，取決於libcurl，CUnit,Jansson和一些gnulib模塊。

我已經編譯x86_64-w64-mingw32所有的依賴關係，並安裝下/home/user/mingw64

我運行：

$ 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 

而且我得到這個錯誤：

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是gnulib模塊的一部分。所以我認爲，這個問題是來自於Makefile.am本節：

# Find gnulib headers. 
ACLOCAL_AMFLAGS = -I m4 

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

但我不能找出解決方案。我完全遵循gnulib manual中描述的說明。

Answer 1

我設法找到解決此問題的解決方法。顯然autotools並不像我想的那麼容易。

1. 我不得不再生gnulib模塊，這次指定 --makefile-name參數。即。

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

2. 我刪除lib/Makefile從automake的在configure.ac生成的文件。因此，而不是：

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

   現在我有：

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

3. 我Makefile.am刪除lib形式SUBDIRS。即。相反的：

   # Subdirectories to descend into. 
   SUBDIRS = po lib 
   

   我：

   # Subdirectories to descend into. 
   SUBDIRS = po 
   

4. 我創建了lib目錄中的新文件名爲local.mk與此內容：

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

5. 而且在Makefile.am包括它。

   include $(top_srcdir)/lib/local.mk 
   

6. 最後我不得不運行此命令：

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

就是這樣。
