Qmake在非Qt程序中的使用

Qmake通常被人们用在Qt程序中，生成Makefile，其实，Qmake可以辅助编译非Qt程序的。

一、无任何第三方库 的程序的编译
这个程序是计算最小公倍数和最大公约数的

#include<stdio.h>unsigned long long LCM (unsigned long m , unsigned long n){unsigned long long a = m , b= n;while (a != b){ if (a < b) a += m ;else b+= n;}return a ;}unsigned long GCD (unsigned long m , unsigned long n){while (m != n){ if (m < n) n-= m ;else m -= n;}return m ;}int main (){ unsigned long a , b;scanf ("%lu%lu" , & a , & b);printf ("%I64u /n %I32u /n " , LCM (a , b), GCD (a , b));return 0 ;}

新建一个pro文件，内容是

TEMPLATE = app
TARGET = gcd
CONFIG= release
SOURCES += gcd.c

然后qmake ，mingw32-make 即可
C:/Documents and Settings/DELL/桌面/test> qmake
C:/Documents and Settings/DELL/桌面/test> mingw32-make
gcc -c -O2 -DUNICODE -DQT_LARGEFILE_SUPPORT -I"d:/Qt/4.6.2/mkspecs/win32-g++" -o gcd.o gcd.c
g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -Wl,-s -o wayne.exe gcd.o
C:/Documents and Settings/DELL/桌面/test> wayne

二、第三方库程序的编译
这个演示程序是用来计算所有的水仙花数的，代码 作者是medie2005，调用了gmp库

 

 

#include <cstdlib>#include <iostream>#include <windows.h>#include <cmath>#include "gmp.h"using namespace std;const int L=40;mpz_t Hash[10][L];mpz_t dif[10][10][L];mpz_t POW10[L];char str[L<<1];void Init( ){ unsigned i, j; for( i=0; i<10; ++i ){ for( j=0; j<L; ++j ) mpz_init( Hash[i][j] ); } mpz_set_ui( Hash[0][0], 0 ); mpz_init_set_ui( POW10[0], 1 ); for( i=1; i<10; ++i ) mpz_set_ui( Hash[i][0], 1 ); for( j=1; j<L; ++j ){ mpz_init( POW10[j] ); mpz_mul_ui( POW10[j], POW10[j-1], 10 ); } for( i=0; i<10; ++i ){ for( j=1; j<L; ++j ){ mpz_mul_ui( Hash[i][j], Hash[i][j-1], i ); } } for( int k=0; k<L; ++k ){ for( i=0; i<10; ++i ){ for( j=0; j<10; ++j ){ mpz_init( dif[i][j][k] ); mpz_sub( dif[i][j][k], Hash[i][k], Hash[j][k] ); } } }}void Clean( ){ unsigned i, j; for( i=0; i<10; ++i ) for( j=0; j<L; ++j ){ mpz_clear( Hash[i][j] ); } for( j=0; j<L; ++j ) mpz_clear( POW10[j] ); for( int k=0; k<L; ++k ){ for( i=0; i<10; ++i ){ for( j=0; j<10; ++j ){ mpz_clear( dif[i][j][k] ); } } }}bool check( mpz_t &n, int *c ){ int i, d[10]={0}; mpz_get_str( str, 10, n ); for( i=0; str[i]!='/0'; ++i ){ d[str[i]-'0']++; if( d[str[i]-'0']>c[str[i]-'0'] ) return false; } return true;}void combination( unsigned n, unsigned m ){ int *c=new int[m+2], j, *num=new int[m+2]; int dig[10]={0}; dig[0]=m; for( j=1; j<=m; ++j ) c[j]=j-1, num[j]=c[j]-j+1; c[m+1]=n; mpz_t number; mpz_init_set_ui( number, 0 );R2: if( mpz_cmp( number, POW10[m-1] )>0 && mpz_cmp( number, POW10[m] )<0 && check( number, dig ) ){ mpz_out_str( stdout, 10, number ); printf("/n"); } if( m&1 ) if( c[1]+1<c[2] ){ --dig[num[1]]; mpz_add( number, number, dif[num[1]+1][num[1]][m] ); ++c[1], ++num[1]; ++dig[num[1]]; goto R2; } else{ j=2; goto R4; } else if( c[1]>0 ){ --dig[num[1]]; mpz_sub( number, number, dif[num[1]][num[1]-1][m] ); --c[1], --num[1]; ++dig[num[1]]; goto R2; } else{ j=2; goto R5; };R4: if( c[j]>=j ){ if( j<=m ){ --dig[num[j]]; mpz_sub( number, number, dif[num[j]][c[j-1]-j+1][m] ); } if( j-1<=m ){ --dig[num[j-1]]; mpz_sub( number, number, dif[num[j-1]][0][m] ); } c[j]=c[j-1], num[j]=c[j]-j+1; c[j-1]=j-2, num[j-1]=c[j-1]-(j-1)+1; if( j<=m ) ++dig[num[j]]; if( j-1<=m ) ++dig[num[j-1]]; goto R2; } else ++j;R5: if( c[j]+1<c[j+1] ){ if( j<=m ){ --dig[num[j]]; mpz_sub( number, number, dif[num[j]][c[j]+1-j+1][m] ); } if( j-1<=m ){ --dig[num[j-1]]; mpz_sub( number, number, dif[num[j-1]][c[j]-j+2][m] ); } c[j-1]=c[j], num[j-1]=c[j-1]-(j-1)+1; c[j]=c[j]+1, num[j]=c[j]-j+1; if( j<=m ) ++dig[num[j]]; if( j-1<=m ) ++dig[num[j-1]]; goto R2; } else{ ++j; if( j<=m ) goto R4; } delete []c; delete []num; mpz_clear( number );}int main(int argc, char *argv[]){ int time=GetTickCount(); Init(); for( unsigned i=3; i<L; ++i ){ cout<<i<<" digits search start!/n"; combination( i+9, i ); } Clean( ); cout<<"time : "<<GetTickCount()-time<<" ms/n"; cout<<"press any key to continue.../n"; cin.get(); return EXIT_SUCCESS;}

编写一个pro文件，内容是

TEMPLATE = app
TARGET = daffodil
CONFIG= release
INCLUDEPATH +=include
LIBS +=-Llib -lgmp
HEADERS += include/gmp.h
SOURCES += daffodil.cpp

然后qmake ，mingw32-make ：

C:/Documents and Settings/DELL/桌面/nb/gmp> qmake

C:/Documents and Settings/DELL/桌面/nb/gmp> mingw32-make
g++ -c -O2 -DUNICODE -DQT_LARGEFILE_SUPPORT -I"include" -I"d:/Qt/4.6.2/mkspecs/win32-g++" -o daffodil.o daffodil.cpp
g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -Wl,-s -o daffodil.exe daffodil.o  -Llib -lgmp

C:/Documents and Settings/DELL/桌面/nb/gmp> daffodil.exe
