建筑物开罗的Windows使用MinGW（连接问题的libpng） [英] Building Cairo for Windows with MinGW (Problems linking libpng)

问题描述

我试图建立在Windows上使用MinGW的（和MSYS）开罗。我下面的编译GTK + 2.16.4用于Windows ，但我使用的是最新版本只要有可能，例如：

• 的zlib-1.2.3


• 的libpng-1.2.42


• pixman-0.17.4


• 开罗-1.8.8

这工作pretty很好，直到当我尝试构建实际的开罗。在配置成功，但要在开罗似乎有链接到我的libpng构建问题。过了一会儿，我得到的错误一长串像这样的：

的.libs /开罗png.o：在功能`png_simple_error_callback：
/home/user/cairo-1.8.8/src/cairo-png.c:95：未定义参考`png_get_error_ptr
的.libs /开罗png.o：在功能`png_simple_warning_callback：
/home/user/cairo-1.8.8/src/cairo-png.c:112：未定义参考`png_get_error_ptr...的.libs /开罗png.o：在功能`stream_read_func：

我一直在使用的libpng（1.2.40较旧版本的尝试，该版本由的GTK +项目），具有相同的结果。当我运行pkg配置-cflags -libs的libpng我得到-IC：/ MinGW的/有/填实：libpng12 -LC：/ MinGW的/ lib目录-lpng12，这似乎是正确的。我敢肯定，我在做一些愚蠢的错误，但我不能告诉你它是什么。

解决方案

显然，这是一个已知的问题。我不知道如何成功地错过它，因为它是在的博客，我是下（我认为这是安全的假设，这也适用于Windows 7，因为我试过的第三项建议，并将其固定我的问题）：

  

现在，让我们开始安装MinGW的。需要注意的是MinGW的没有在Windows Vista流畅运行，因为怪异的文件系统的限制。解决方法是

  
• 要在FAT文件系统上安装的MinGW，

  
• 要在安全模式下工作，或

  
• 要使用MinGW的便携式据说这是运作良好。

  

I'm trying to build cairo on Windows using MinGW (and MSYS). I am following the instrucions on Compiling GTK+ 2.16.4 for Windows, except that I'm using the latest versions whenever possible, i.e:

• zlib-1.2.3
• libpng-1.2.42
• pixman-0.17.4
• cairo-1.8.8

This works pretty well up until when I try to build the actual cairo. The configuration succeeds, but during make cairo seems to have problems linking to my build of libpng. After a little while I get a long list of errors such as this:

.libs/cairo-png.o: In function `png_simple_error_callback':
/home/user/cairo-1.8.8/src/cairo-png.c:95: undefined reference to `png_get_error_ptr'
.libs/cairo-png.o: In function `png_simple_warning_callback':
/home/user/cairo-1.8.8/src/cairo-png.c:112: undefined reference to `png_get_error_ptr'

...

.libs/cairo-png.o: In function `stream_read_func':
/home/user/cairo-1.8.8/src/cairo-png.c:686: undefined reference to `png_error'
collect2: ld returned 1 exit status
make[3]: *** [libcairo.la] Error 1
make[3]: Leaving directory `/home/user/cairo-1.8.8/src'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/home/user/cairo-1.8.8/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/user/cairo-1.8.8'
make: *** [all] Error 2

I have tried using an older version of libpng (1.2.40, the version being distributed by The GTK+ Project), with the same result. When I run "pkg-config -cflags -libs libpng" I get "-IC:/MinGW/include/libpng12 -LC:/MinGW/lib -lpng12", which seems correct. I'm sure I'm making some stupid mistake, but I cannot tell what it is.

解决方案

Apparently this is a known issue. I don't know how managed to miss it, given that it is even mentioned in the blog that I was following (I think it's safe to assume that this also applies to Windows 7, given that I tried the third suggestion and it fixed my problem):

Now, let's install MinGW. Note that MinGW doesn't run smoothly on Windows Vista because of weird filesystem restrictions. The workaround is

• to install MinGW on FAT filesystem,
• to work in the safe mode, or
• to use MinGW Portable which is said to be working well.
