Обсуждение: Cross-compiling under linux for Windows

I'm trying to cross-compile postgresql-8.1.4 for windows under Debian
Linux. This is how I've tried to run configure:

CC=i586-mingw32msvc-gcc RANLIB=i586-mingw32msvc-ranlib ./configure \
--prefix=/usr/local/stow/pg-msw-8.0.4/msw-dev/ --host i586-pc-mingw32 \
--without-zlib --disable-shared

However, not very successfully:

- I have to run i586-mingw32msvc-ranlib manually for
  src/port/libpgport.a and src/port/libpgport_srv.a
- have to edit few makefiles to change windres to 586-mingw32msvc-windres

And still, no go:


i586-mingw32msvc-gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-after-statement
-Wendif-labels-fno-strict-aliasing initdb.o win32ver.o -L../../../src/port -lpgport -L../../../src/interfaces/libpq
-lpq -L../../../src/port -Wl,--allow-multiple-definition   -lpgport -lwsock32 -lm  -lws2_32 -lshfolder -o initdb.exe

collect2: ld returned 1 exit status
make[3]: *** [initdb] Error 1
make[3]: Leaving directory `/home/tavasti/work/postgres/postgresql-8.1.4/src/bin/initdb'

In fact all I would essentially need is static libpq.a, but even that doesn't
look very good:

-rw-rw-r--  1 tavasti tavasti     8 Jun 28 10:55 libpq.a

At least one problem was here:

0
tavasti@aladobix:~/work/postgres/postgresql-8.1.4/src/interfaces/libpq$make
ar crs libpq.a `lorder fe-auth.o fe-connect.o fe-exec.o fe-misc.o \
fe-print.o fe-lobj.o fe-protocol2.o fe-protocol3.o pqexpbuffer.o \
pqsignal.o fe-secure.o md5.o ip.o wchar.o encnames.o noblock.o \
pgstrcasecmp.o thread.o crypt.o inet_aton.o getaddrinfo.o open.o \
snprintf.o win32.o libpqrc.o | tsort`
nm: fe-auth.o: File format not recognized ...


Running lorder to find what to link is problem. lorder did not
understand file format, so nothing get's into the library.

This works:

ar crs libpq.a fe-auth.o fe-connect.o fe-exec.o fe-misc.o fe-print.o \
fe-lobj.o fe-protocol2.o fe-protocol3.o pqexpbuffer.o pqsignal.o \
fe-secure.o md5.o ip.o wchar.o encnames.o noblock.o pgstrcasecmp.o \
thread.o crypt.o inet_aton.o getaddrinfo.o open.o snprintf.o win32.o \
libpqrc.o

So I got what I needed, so I didn't start checking whole build system
to make it cross-compiling compatible. Hopefully this helps someone
else in future.
