[Gnuwin32-users] Compliation of libiconv under mingw/msys

[James M. D. <mdu...@ya...>]

Dear Sirs,

I Have installed the lastest cygwin, and mingw.
Am running mys 1.0.

gcc -v  returns : 
Reading specs from
c:/development/mingw32/bin/../lib/gcc-lib/mingw32/2.95.3-6/specs
gcc version 2.95.3-6 (mingw special)

I am compiling the libiconv from 
http://belnet.dl.sourceforge.net/sourceforge/gnuwin32/libiconv-1.7-src.zip

First I run :
 make -f makefile.mingw

"checking for Cygwin environment... (cached) no
checking for mingw32 environment... (cached) yes
checking for executable suffix... (cached) .exe
checking build system type... i386-pc-mingw32"
All looks good :

Then I make and get the following error :

undefined reference to `WinMain@16'

-------------------------------------------------------------

/bin/sh ../libtool --mode=link gcc -O  -o libcharset.la -rpath

-------------------------------------------------------------
If if delete the config.cache, config.status and config.log and
reconfigure, or just change the prefix, then this problem goes away.


I also setup the config.site as instructed, but this is not needed yet
for the low level modules, so I build without it:
but had to remove these libs :#-lintl -liconv -liberty
and these includes that where not there yet :
#INCLUDES=" $INCLUDES -Ic:/development/mingw32/include/libc "


I had to delete the config.status, config.cache and config.log for it
to build properly.

All goes fine untill make install, 
then I get a strange error  :
--------------------------------------------------
[....]
/usr/bin/install.exe -cpD -m 644 .libs/libcharset.a
c:/progra~1/libiconv/lib/libcharset.a

--------------------------------------------------
It seems that the name gets cut off after the "~".
If i reconfigure to :
--prefix=c:/mingw/libiconv
then the build works ok.

You will find my patched version here:
http://introspector.sourceforge.net/dia/current_clean.tgz

The diff file is here :
http://introspector.sourceforge.net/dia/diff_ming

I wonder if you have similar problems building the libiconv?

I am looking forward to your comments,
thanks for the good tools,

Mike
