[icu-support] Building and installing ICU 50.1.2 on Windows 7 64 bits with MinGW

[Filipe D. M. <fdm...@ap...>]

Hello,

I'm trying to build and use ICU on Windows 7 64bits with msys +
mingw-w64. I'm able to build ICU successfully like this:

fdmanana@fdmanana-win ~/tmp$ tar zxf icu4c-50_1_2-src.tgz
fdmanana@fdmanana-win ~/tmp$ cd icu/source/
fdmanana@fdmanana-win ~/tmp/icu/source$ ./runConfigureICU MinGW && make install

This commands terminates successfully, installing icu-config into
/usr/local/bin/.
However when I try to run icu-config, I get:

fdmanana@fdmanana-win ~$ /usr/local/bin/icu-config --ldflags
### icu-config: Can't find /usr/local/lib/libicuuc.dll - ICU prefix is wrong.
###      Try the --prefix= option
###      or --detect-prefix
###      (If you want to disable this check, use  the --noverify option)
### icu-config: Exitting.

Looking at /usr/local/lib/, I noticed I have a file named icuuc.dll
and not libicuuc.dll, so I copied the former into libicuuc.dll

fdmanana@fdmanana-win ~$ cp /usr/local/lib/icuuc.dll
/usr/local/lib/libicuuc.dll

After this, icu-config works. But using it with --ldflags, it gives me
ld flags that refer to 2 library files (cui18n and icudata) that were
not built:

fdmanana@fdmanana-win ~$ /usr/local/bin/icu-config --ldflags
-L/local64/lib  -lpthread -lm   -L/usr/local/lib -licui18n -licuuc
-licudata  -lpthread -lm
fdmanana@fdmanana-win ~$
fdmanana@fdmanana-win ~$ ls /usr/local/lib/
icu          icuin.dll    icuio.lib    icule50.dll  icutest.dll
icutu.lib    icuuc50.dll   pkgconfig
icudt.dll    icuin.lib    icuio50.dll  iculx.dll    icutest.lib
icutu50.dll  libicuuc.dll
icudt.lib    icuin50.dll  icule.dll    iculx.lib    icutest50.dll
icuuc.dll    libsnappy.a
icudt50.dll  icuio.dll    icule.lib    iculx50.dll  icutu.dll
icuuc.lib    libsnappy.la
fdmanana@fdmanana-win ~$
fdmanana@fdmanana-win ~$ find /usr -name '*icui18n*'
fdmanana@fdmanana-win ~$ find /usr -name '*icuuc*'
/usr/local/lib/icuuc.dll
/usr/local/lib/icuuc.lib
/usr/local/lib/icuuc50.dll
/usr/local/lib/libicuuc.dll
fdmanana@fdmanana-win ~$ find /usr -name '*icudata*'
/usr/local/include/unicode/icudataver.h
fdmanana@fdmanana-win ~$

On a Linux system (icu 4.8.1.1), I surely have icui18n and icudata (as
/usr/lib/libicui18n.{a,so} and /usr/lib/libicudata.{a,so}).
I have no idea why the Windows/MinGW build didn't produce these 2
libraries, as they should exist according to icu-config --ldflags

Some environment details:
