目标文件有太多的部分 [英] Object file has too many sections

问题描述

我们正在大量使用的boost ::序列化和模板一般。一切似乎很顺利。

We am making heavy use of boost::serialization and templates in general. All seems to be going well.

除，我们已经打在我们的Windows构建一个障碍。它似乎导致在对象文件是太大的问题。我们使用的MinGW / MSYS使用g ++ 4.7.0。

Except, we've hit a snag on our Windows builds. It seems to cause issues in the object files being too large. We're using MinGW/Msys with g++ 4.7.0.

c:/mingw/bin/../lib/gcc/mingw32/4.7.0/../../../../mingw32/bin/as.exe: CMakeFiles/source.dir/sourcecode.cpp.obj: too many sections (33396)

法师谷歌透露了这一消息存档，<一个href=\"http://sourceforge.net/mailarchive/forum.php?thread_name=CA%2Bsc5mkLvj%3DW9w2%3DsY%3Dc_N%3DEwnsQuPDEX%3DiBcbsbxS3CuE_5Bg%40mail.gmail.com&forum_name=mingw-users\">http://sourceforge.net/mailarchive/forum.php?thread_name=CA%2Bsc5mkLvj%3DW9w2%3DsY%3Dc_N%3DEwnsQuPDEX%3DiBcbsbxS3CuE_5Bg%40mail.gmail.com&forum_name=mingw-users

在它时，表明另一人击中pretty大体相同抽丝。它确实点到了Visual Studio的 / bigobj 选项一个选项，这似乎做什么，我们都需要。但是，我们无法移动到Visual Studio。

In it, it indicates that another person hit pretty much the same snag. It did point to an option for Visual Studio's /bigobj option which appears to do what we would need. However, we're unable to move to Visual Studio.

一个建议是--hash大小添加到汇编器选项。这并没有帮助。

One suggestion was to add --hash-size to the assembler options. This did not help.

如果我没有记错的话，问题就在于，对象文件，有在其中2 ^ 16项的限制。事实上，根据错误信息，我敢说，这是一个签名的2 ^ 16个条目，但是这是花生。适用于Visual Studio的 / bigobj 选项将改变为2 ^ 32。邮件列表的结果不知道gcc的等效选项。另外谷歌的结果似乎不相关了这一点。

If I'm not mistaken, the issue lies in the fact that the object files have a limit of 2^16 entries in them. Actually, according to the error message, I would venture that it's a signed 2^16 entries, but that's peanuts. The /bigobj option for Visual Studio would change that to 2^32. The mailing list result did not know of an equivalent option for gcc. Further google results don't appear to be relevant to this.

在这一点上，我们将不得不重构我们的code（啊）来解决这个限制。不过，我仍然关注的是，沉重的模板，我们可以一次又一次地跑入的问题（我们已经有三个源文件碰上它）。

At this point we'll have to refactor our code (ugh) to get around this limitation. But I am still concerned that, with heavy templating, we could run into the issue again and again (we've already run into it with three source files).

所以我的问题是这样;有没有GCC相当于微软的 / bigobj 选项？有没有我还没有找到第三种选择？

So my question is thus; is there a gcc equivalent to Microsoft's /bigobj option? Is there a third option that I'm not yet found?

推荐答案

解决的办法是添加选项 -Wa，-mbig-OBJ 如果你的GCC支持的版本该选项。你可能只在编译步骤，而不是一步连接器需要它。

The solution is to add the option -Wa,-mbig-obj if your version of GCC supports that option. You probably only need it during the compilation step, not the linker step.

如果你的编译器不支持该选项，你应该考虑使用的MinGW-W64和 MSYS2 。

If your compiler does not support that option, you should look into using mingw-w64 and MSYS2.
