构建GCC交叉编译器（从“Linux”到“Windows”） [英] Building GCC cross compiler (from "Linux" to "Windows")

问题描述

我想建立gcc交叉编译器，在Linux环境下编译c / c ++应用程序，但对于Windows目标。

I want to build "gcc cross-compiler" to compile "c/c++" applications on "Linux" environment but for "Windows" target.

到目前为止：

I have made this so far:

1. 安装了必要的工具和软件包，用于在 GCC的先决条件页面。

来源：

gcc-core-4.4.1 ， gcc-g ++ - 4.4.1 ， binutils-2.19.1 ， w32api-3.13-mingw32 ， mingwrt-3.16-mingw32

为最终的交叉编译器创建了此目录层次结构：

$ {HOME} / gcc /
$ {HOME} / src / - 对于源

$ {HOME} / src / build-binutils / i386-mingw32 / - 用于将binutils构建为i386-mingw32目标

$ {HOME} / src / build-gcc / i386-mingw32 / - 用于将gcc构建为i386-mingw32目标

Created this directory hierarchy:
"${HOME}/gcc/" - for final cross-compiler
"${HOME}/src/" - for sources
"${HOME}/src/build-binutils/i386-mingw32/" - for building binutils to "i386-mingw32" target
"${HOME}/src/build-gcc/i386-mingw32/" - for building gcc to "i386-mingw32" target

Builded binutils package：

Builded binutils package:

cd$ {HOME} / src / build-binutils / i386-mingw32 /

.. /../binutils-2.19.1/configure --prefix =$ {HOME} / gcc--target = i386-mingw32 --disable-nls

make

make install

cd "${HOME}/src/build-binutils/i386-mingw32/"
../../binutils-2.19.1/configure --prefix="${HOME}/gcc" --target=i386-mingw32 --disable-nls
make
make install

将w32api和mingwrt标题复制到安装目录：

Copied "w32api" and "mingwrt" headers to the install directory:

cp -R$ {HOME} /src/w32api-3.13-mingw32/include$ {HOME} / gcc / i386-mingw32

cp -R$ {HOME} / src / mingwrt- 3.16-mingw32 / include$ {HOME} / gcc / i386-mingw32

cp -R "${HOME}/src/w32api-3.13-mingw32/include" "${HOME}/gcc/i386-mingw32"
cp -R "${HOME}/src/mingwrt-3.16-mingw32/include" "${HOME}/gcc/i386-mingw32"

现在，当我试图构建c（只）交叉编译器：

And now when I am trying to build the "c (only) cross-compiler":

cd "${HOME}/src/build-gcc/i386-mingw32/"
../../gcc-4.4.1/configure --prefix="${HOME}/gcc" --target=i386-mingw32 --enable-languages=c --with-headers="${HOME}/gcc/i386-mingw32/include" --disable-nls
make<br>

它正在构建大约4分钟，然后给我这些错误：

it was building something about 4 minutes and then gives me these errors:

${HOME}/gcc/i386-mingw32/bin/ld: dllcrt2.o: No such file: No such file or directory
collect2: ld returned 1 exit status
make[2]: *** [libgcc_s.dll] Error 1
make[2]: Leaving directory `${HOME}/src/build-gcc/i386-mingw32/i386-mingw32/libgcc'
make[1]: *** [all-target-libgcc] Error 2
make[1]: Leaving directory `${HOME}/src/build-gcc/i386-mingw32'
make: *** [all] Error 2

那个错误消息我真的不知道现在做什么： - （（。

From that error message I really don't know what to do now :-((( .

有人知道问题在哪里？ br>
谢谢。

Does anybody know where is the problem?
Thanks.

推荐答案

这是真的：事情的方式，你需要

That's actually OK: the way things go, you need to

1. 构建binutils


2. 安装标题


3. 足以创建对象文件，但不足以链接


4. 构建win32api和mingw运行时（其中包括您缺少的 dllcrt2.o ）


5. 构建一个完整的C编译器（以及其他前端，如C ++，Fortran，Ada等等）。

1. build binutils
2. install headers
3. build the a partial C compiler: enough to create object files, but not enough to link
4. build the win32api and mingw runtime (which includes your missing dllcrt2.o)
5. build a complete C compiler (and other front-ends, such as C++, Fortran, Ada, whatever, if you want them)

您已成功执行上述步骤3;它失败构建libgcc（这是一个GCC支持库），但这意味着C编译器核心是functionnal（虽然它将无法链接，它仍然可以创建有效的目标文件）。您可以通过查看GCC构建目录中的 gcc / xgcc 文件来检查。

You have successful performed step 3 above; it fails building libgcc (which is a GCC support library), but that means the C compiler core is functionnal (although it won't be able to link, it can still create valid object files). You can check that by looking at the gcc/xgcc file in your GCC build directory.

（要真正安装部分C编译器，您应该运行 make 使用 -k 选项，让它做到最好，即使面对错误，例如，使用 make - k install 。）

(To actuall install the partial C compiler, you should run make with the -k option, to have it do it best, even in the face of errors. For example, use make -k install.)
