cygwin64'den 32bit kodu derleyin

Question

Cycwin64'ü bir win7-64'e gcc dev araçlarıyla yükledim ve 64 bitlik ikili dosyalar ürettiğini fark ettim. (Şaşırtıcı değil: o) Bazı 32bit ikili üreten bu yapmak için bir ortalama var mı?

Windows için çalıştığım 64bit derlenmiş olan socat aracını derledim, ancak XP-32 için başka bir sürüm oluşturmaya çalışıyorum.

configure komut ben this thread den ming64 için görmüş olmalı ki (bir -b 32 anahtarı desteklemek için görünmüyor, ben configure için CFLAGS yılında -m32 anahtarı belirtmek çalışırsanız başarısız:

$ CFLAGS=-m32 ./configure 
checking which defines needed for makedepend... 
checking for a BSD-compatible install... /usr/bin/install -c 
checking for gcc... gcc 
checking whether the C compiler works... no 
configure: error: in `/cygdrive/c/dev/tools/nettools/socat/socat-2.0.0-b8': 
configure: error: C compiler cannot create executables 
See `config.log' for more details 

ediyorum seçeneği de Cygwin32 yüklemeye olabilir veya başka bir ayar veya ek cygwin paketi ile 32bit kodunu derlemek olabilir

Düzenleme:? Ben foun Benim cygwin64/gcc 32bits basit hello.c program derleme olamaz d:

#include <stdio.h> 

int main (int argc, char *argv[]){ 
    printf("Hello, world!\n"); 
    return 0; 
} 

sorunsuz çalışan bir gcc -o hello.exe hello.c ile

fakat gcc -o hello.exe hello.c -m32

Answer 1

Cygwin paketleri-cygwin to-cygwin çapraz toolchain içeren sağlar tükürür . 64-bit Cygwin ve 32-bit Cygwin 64-bit bina için cygwin64-* paketleri 32-bit bina için cygwin32-* paketleri vardır.

Onları hiç kullanmadım, ama onlar herhangi çapraz toolchain olarak hemen hemen çalışmaya varsayalım, böylece ./configure adıma doğru --host ve --build argümanları geçmelidir.

Answer 2

Derleyiciye -32 eklenmesi, doğru kitaplıkları seçmesini sağlamaz. I686-pc-cygwin-gcc derleyicisinin yüklü olup olmadığını kontrol etmelisiniz. Eğer böyle bir şey yapmak zorunda olduğunu derleyici kullanmak için:

./configure --target = i686-pc-cygwin
