無法在Netbeans（Cygwin）上使用libbgi.a編譯C ++程序

Question

我正在嘗試編譯舊的基於graphics.h的動畫程序。 我下載libbgi.a及其關聯頭文件從WinBGIm並遵循從說明這里 （那時的代碼塊，但我試圖遵循Netbeans的類似步驟）。 當我嘗試構建時，它在鏈接期間顯示錯誤（如下所示）。

請告訴我怎么了？

libbgi.a位於/lib/文件夾中，並且其關聯的頭文件位於/usr/include文件夾中。

碼：

#include <stdio.h>
#include <stdlib.h>
#include <graphics.h>
#include <string.h>

int main() {
    int gdriver = DETECT, gmode, errorcode;
    initgraph(&gdriver, &gmode, (char*) "");
    errorcode = graphresult();
    /* an error occurred */
    if (errorcode != grOk) {
       printf("Graphics error: %s\n", grapherrormsg(errorcode));
       printf("Press any key to halt:");
       getch();
       exit(1);
    }

    getch();
    closegraph();
    return 0;
}

編輯：

遵循以下步驟：

mkdir junk; cd junk
ar x /usr/lib/libbgi.a
file *.o

我得到以下輸出：

Answer 1

盡管gcc的-m32 （ [GNU.GCC]：x86選項 ）運作良好，但是在Cygwin上仍然存在一些問題。

回顧一下，您試圖在64位 Cygwin上構建32位應用程序（使用一些32位構建的static lib ）。
即使有一系列步驟可以實現您的目標，最簡單的方法是安裝32位 gcc工具鏈。

例：

 [cfati@cfati-5510-0:/cygdrive/e/Work/Dev/StackOverflow/q057461809]> ~/sopr.sh *** Set shorter prompt to better fit when pasted in StackOverflow (or other) pages *** [064bit prompt]> uname -a CYGWIN_NT-10.0 cfati-5510-0 3.0.7(0.338/5/3) 2019-04-30 18:08 x86_64 Cygwin [064bit prompt]> [064bit prompt]> which g++ /usr/bin/g++ [064bit prompt]> GPPS="/usr/bin/g++ /usr/bin/x86_64-pc-cygwin-g++.exe /usr/bin/i686-pc-cygwin-g++.exe" [064bit prompt]> echo ${GPPS} /usr/bin/g++ /usr/bin/x86_64-pc-cygwin-g++.exe /usr/bin/i686-pc-cygwin-g++.exe [064bit prompt]> [064bit prompt]> for GPP in ${GPPS}; do ll ${GPP}; done -rwxr-xr-x 4 cfati None 936467 Dec 9 2018 /usr/bin/g++ -rwxr-xr-x 4 cfati None 936467 Dec 9 2018 /usr/bin/x86_64-pc-cygwin-g++.exe -rwxr-xr-x 2 cfati None 931347 Apr 17 2018 /usr/bin/i686-pc-cygwin-g++.exe [064bit prompt]> [064bit prompt]> for GPP in ${GPPS}; do md5sum ${GPP}; done 71b02af056efb46a3e66279ce80e554f */usr/bin/g++ 71b02af056efb46a3e66279ce80e554f */usr/bin/x86_64-pc-cygwin-g++.exe 4642d1d76335bf5394e7c0917acf13d0 */usr/bin/i686-pc-cygwin-g++.exe [064bit prompt]> [064bit prompt]> for GPP in ${GPPS}; do cygcheck -f ${GPP}; done gcc-g++-7.4.0-1 gcc-g++-7.4.0-1 cygwin32-gcc-g++-7.3.0-1 

如圖所示， g ++和x86_64-pc-cygwin-g ++相同（通常，前者應該是到后者的符號鏈接 ），而i686-pc-cygwin-g ++是您所需要的。
安裝其軟件包（ cygwin32-gcc-g ++-* ）及其所有依賴項（如下所示），並在嘗試構建時使用該可執行文件。

或者，您可以安裝32位 Cygwin （兩種變體可以愉快地共存於同一台計算機上-我在筆記本電腦上都安裝了它們）並嘗試在那里構建。
