支持下
等以后有时间我也开始研究下WC。

watcom在XP下新建选dos-32->dos/4GW
把程序写好了后，Targets->make 也没有错误，run可一闪就过了,写getch()了呀？

/* Svga64k.bgi 测试文件 */

#include "graphics.h"
#include "Svga256.h"
#include "stdio.h"
#include "fcntl.h"
#include "malloc.h"
#include "io.h"

int huge Return_SVGA256(void)
{
return(SVGA320x200x256); /* 返回各种分辨率的对应编号 0～6 宏定义参见 Svga256.h */
}

int main(void)
{
int width, height, i=DETECT, j=0, x0, y0, fp;
unsigned char fix, *buffer, pix24b[4];
DacPalette256 dac256;
installuserdriver("Svga256", Return_SVGA256); /* 对于svga256必需执行该函数以安装BGI驱动 */
initgraph(&i, &j, ""); /* 执行TC默认的BGI初始化函数 */

if((fp = open("xy_256.bmp", O_RDONLY | O_BINARY)) == -1)
{
puts("Can't find file ""xy_256.bmp"".");
return 1;
}
lseek(fp, 18, SEEK_SET);
read(fp, &width, 4);
read(fp, &height, 4);
fix = (width % 4) ? (4 - width % 4) : 0;
x0 = (320 - width) / 2;
y0 = (200 - height) / 2;
lseek(fp, 54, SEEK_SET);
for(i = 0; i < 256; i++) /* 按照该图片的DAC色表设置色彩寄存器 */
{
read(fp, pix24b, 4); /* 读取DAC分量信息 */
/* 设置调色板 */
dac256[i][0] = pix24b[2] >> 2;
dac256[i][1] = pix24b[1] >> 2;
dac256[i][2] = pix24b[0] >> 2;
}
setvgapalette256(&dac256); /* 应用调色板, 定义参见 Svga256.h */
buffer = (unsigned char *)malloc(width);
for(j = height - 1; j >= 0; j--)
{
read(fp, buffer, width);
lseek(fp, fix, SEEK_CUR);
for(i = 0; i < width; i++)
putpixel(x0+i, y0+j, buffer[i]);
}
free(buffer);
close(fp);
getch();
closegraph();
return 0;
}

这是win-tc下一个第三方BGI的一个程序，在win-tc好使，但到了watcom就出现下面的错误了，一些头文件，我已经 拷入到C:\WATCOM\h中去了，svga256.bgi和程序文件也在同一个目录下，怎么会出现错误呢？

WC提供的函数库除了提供标准C\c++库的函数外还拥有
Heap Functions / Process Primitive Functions / Process Environment / Operating System I/O Functions /Console I/O Functions / Default Windowing Functions / BIOS Functions /DOS-Specific Functions / Intel 80x86 Architecture-Specific Functions / Intel Pentium Multimedia Extension Functions等其他函数
WC的支持库包括：
图形库 : SciTech's MGL； wxWindows；WGT Watcom C/C++ ；Xlib Watcom C/C++； Watcom C/C++ ModeX；PD Curses; IFF Software；JLIB ；Zephyr's ZSVGA ；gkit ；StelSOFT GDK ；Allegro D-Flat；OWL NExt ；Turbo Vision+ ；libpng ；
音频库 : VAT Watcom C/C++ ；SMIX Watcom C/C++ ；DSIK Watcom C/C++
及其他工具库dllPower ；STLPort ；XBase ；zlib 等等。

这些函数在那能下载，怎么使用呀？特别是图形库

那段程序肯定不行的，光是#include "graphics.h"在OW下就没有，到哪个山头唱哪支喝，TC有些私有的并非放之四海皆可的。
那些函数OW自带的，那些图形库可以到google上找，也可以关注
http://www.ds0101.com
现在已经有一些了，我会陆续更新这方面的东东进去。

你说的“OW的文档”是指它的IDE文档吗？

不单是IDE的文档，OW 1.6会在开始菜单里建立一个子菜单，里面应该有近十个帮助文件，涉及到C库函数、C＋＋类库、IDE使用、调试方法、用户手册等等等等。可谓很全面了，只不过都是E文的。

这些错误是因为环境变量没有正确配置导致的吗 ？
