使用MinGW 编译 iconv 库

已有的环境:msys2.0, mingw, GnuWin32工具集

解压后先别急着configure
先看看 README.woe32

Building requires the mingw or cygwin development environment (includes gcc).
I recommend to use the cygwin environment as the development environment
and mingw only as the target (runtime, deployment) environment.
For this, you need to install

  • cygwin,
  • the mingw runtime package, also from the cygwin site.

首先安装cygwin,
进入目录后执行 ./configure , 第一个问题

checking if gcc supports -fno-rtti -fno-exceptions... ./configure: line 7594: diff:
command not found

缺个diff.exe,用everything 搜索到 C:\Program Files (x86)\GnuWin32\bin 下面有一个,复制到 C:\cygwin64\bin,
先不急着执行./configure,单独执行diff.exe 提示缺少 libintl3.dll,将这个文件也复制过来,
再次执行diff.exe 提示缺少 libiconv2.dll,再复制,没问题了。
(如果你从别的地方获取diff,可能不需要依赖dll,也可能依赖别的库,用类似的方法配置齐全就是了)

执行 ./configure 没有出现明显问题

执行 make ,提示

./relocatable.c: In function 'libcharset_relocate':
:0:12: error: expected expression before '/' token
./relocatable.c:423:37: note: in expansion of macro 'INSTALLDIR'
const char orig_installdir = INSTALLDIR;
^~~~~~~~~~
make[2]:
** [Makefile:65: relocatable.lo] Error 1
make[2]: Leaving directory 'C:/Users/ViANG/Desktop/libiconv-1.14/libcharset/lib'
make[1]: *** [Makefile:34: all] Error 2
make[1]: Leaving directory 'C:/Users/ViANG/Desktop/libiconv-1.14/libcharset'
make: *** [Makefile:42: lib/localcharset.h] Error 2

好像是说这个 INSTALLDIR 的宏里面,包含了不可预料的表达式(在/之前),但是我也不知道怎么看INSTALLDIR的值,
用grep -R "INSTALLDIR" * 看了一下

build-aux/install-reloc: -D"INSTALLPREFIX="$prefix"" -D"INSTALLDIR
="$installdir"" lib/Makefile:-DENABLE_RELOCATABLE=1 -DIN_LIBRARY -DINSTALLDIR="$(libdir)" -DNO
_XMALLOC lib/Makefile.in:-DENABLE_RELOCATABLE=1 -DIN_LIBRARY -DINSTALLDIR="$(libdir)" -
DNO_XMALLOC

大概是从某个参数中传递进去的,既然它的内容有毒,而且只有一处,那自己改写试试:
找到:libiconv-1.14\libcharset\lib\relocatable.c


const char orig_installdir = INSTALLDIR;
改为
const char
orig_installdir = "/usr/local/cygwin";

同时 mkdir /usr/local/cygwin
然后执行
$ ./configure --prefix=/usr/local/cygwin
$ make
提示错误

C:\MinGW\bin\ranlib.exe: '/cygdrive/c/Users/name/Desktop/libiconv-1.14/lib/libcharset.a':
No such file

试了一下,对于mingw和msys的那一套,可以接受的路径是 /c/usr/...这样的,而在cygwin中的路径是 /cygdrive/c/usr...
试着用sed和grep 批量替换,以及寻找 生成路径的 cygpath命令,修改相应的参数,但还是失败了。

分割线

既然Cygwin 路径和 Msys mingw不兼容,而我对这一系列的东西不太熟,只能再换MSYS试试了
按cygwin的方法把diff.exe和相关的文件复制到 c:/mingw/bin

打开 MSYS2 Shell

$ ./configure
configure: error: cannot guess build type; you must specify one

添加参数:

$ ./configure --build=mingw32

看上去没什么问题

$ make

跑了一大段后,出现前面同样的问题:

./relocatable.c: In function 'libiconv_relocate':
:0:12: error: 'C' undeclared (first use in this function)
./relocatable.c:423:37: note: in expansion of macro 'INSTALLDIR'

^~~~~~~~~~
:0:12: note: each undeclared identifier is reported only once for

^~~~~~~~~~
:0:13: error: expected ',' or ';' before ':' token
./relocatable.c:423:37: note: in expansion of macro 'INSTALLDIR'
const char orig_installdir = INSTALLDIR;
^~~~~~~~~~
make[1]:
** [Makefile:87: relocatable.lo] Error 1
make[1]: Leaving directory 'C:/Users/ViANG/Desktop/libiconv-1.14/lib'
make: *** [Makefile:33: all] Error 2

找到 libiconv-1.14/lib/relocatable.c
改 INSTALLDIR 为 "/usr/local/cygwin" (忘了去mkdir,好像也没什么问题),继续

$ make
$ make install

看上去没什么问题了 :coverface1
