使用mingw在windows上编译libnoise [英] Compiling libnoise on windows with mingw

问题描述

这是我的第一篇文章，如果我做错了，请原谅我。

This is my first post here so forgive me if I've done something wrong.

我一直在努力这个几天，终于决定承诺和寻求帮助。简单地说，我想在Windows上使用mingw编译libnoise（1.0.0）。然而，似乎缺乏在线信息。

I've been struggling with this for a few days and I've finally decided to concede and ask for help. Put simply, I would like to compile libnoise (1.0.0) on windows using mingw. However, there seems to be a lack of information available online.

我已从网站下载源文件，并按照INSTALL文本文件中的说明指示我应该运行命令CXXFLAGS =' - O3 -fomit-框架指针'make（我从mingW shell做）。

I have downloaded the source files from the website and followed the instructions inside the INSTALL text file which indicate that I should run the command "CXXFLAGS='-O3 -fomit-frame-pointer' make" (which I do from the mingW shell).

此操作的输出可在链接（我已链接，而不是发布输出，由于其长度）。如果省略CXXFLAGS或fomit-frame-pointer标志，或者如果我使用mingw32-make或make all命令，输出不会变化太多。

The output from this operation can be found at link (I've linked rather then posting the output due to its length). The output doesn't vary much if I omit the CXXFLAGS or the fomit-frame-pointer flags or if I use the mingw32-make or make all commands.

似乎抱怨缺少文件，例如

It seems to be complaining about missing files such as

Makefile：56 ：../src/latlon.d：没有这样的文件或目录

Makefile:56: ../src/latlon.d: No such file or directory

虽然我可以确认它们存在于目录中。它也在抱怨别的东西。

though I can confirm they exist in the directory stated. It is also complaining about something else

c：/ mingw / bin /../ lib / gcc / mingw32 / 4.7.0 /。 ./../../libmingw32.a(main.o):main.c:(.tex
t.startup + 0xa7）：未定义引用 _WinMain @ 16'collect2。 exe：
错误：ld返回1退出状态make [1]：*** [libnoise.so.0.3]错误

我不知道如何解决这些问题。 google搜索没有真正变成别的单独的博客 post 。这也没有真正帮助，因为我不确定这是什么意思重命名库名称给它一个正确的DLL扩展。一个全部替换将做。

I have no idea how to address these issues. A google search didn't really turn up much other then a single blog post. Which also didn't really help since I am unsure what it means by "Rename the library name to give it a proper DLL extension. A replace-all will do.".

任何帮助或建议将不胜感激，我真的很困惑！ ： - /

Any help or advice would be appreciated, I'm really quite stuck! :-/

干杯

额外信息：我正在运行windows 7，64位和

Extra info: I'm running windows 7, 64 bit and (think) I'm on mingW 4.7.0.

推荐答案

1. 不要担心没有此类文件或目录。这是正常的，请参阅 src / Makefile 的底部来解释。


2. 不要使用目标 。

1. Don't worry about No such file or directory. It's normal, see the bottom of src/Makefile for explanation.
2. Don't ever use target clean. I couldn't recover from that.

3. Remove all directions to build .so files. These are linux files and cannot be built by mingw. Open all the Makefiles and comment out lines containing .so, except the lines:

libnoise：libnoise.so libnoise.a libnoise.la

all：libnoise.a libnoise.la libnoise.so.0.3

在上述行中，只删除包含 .so 。这将阻止构建 .so 目标。

In the above lines only remove the words containing .so. This will prevent building .so targets.

静态库在 src / .libs / libnoise.a 中。

构建DLL 会有点难度，作者使用Visual Studio构建它。没有makefile目标来构建dll。需要准备几行以处理 win32 目录中的文件，并从中生成库。

Building DLL would be a bit harder, as the authors build it using Visual Studio. There are no makefile targets to build the dll. One would need to prepare a few more lines to process files in win32 directory and produce the library out of it.
