本文介绍了其中,以添加CFLAG,如-std = gnu99,成(Eclipse CDT的)自动工具项目的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个简单的自动工具C ++项目(不是C ++),其骨架由Eclipse CDT的(麦浚龙)。

I have a simple Autotools C project (not C++), whose skeleton was created for me by Eclipse CDT (Juno).

CFLAGS(通过检查)似乎是 -g -O2

CFLAGs (by inspection) seem to be -g -O2.

我希望所有的生成make文件也有 -std = gnu99 追加到CFLAGS,因为我用的for(int i = 0; I< MAX;我++)和类似

I want all of the generated make files to also have -std=gnu99 appended to the CFLAGs, because I use for (int i = 0; i < MAX; i++) and similar.

我能明显破解Makefile文件,但这个被覆盖上 ./配置

I can obviously hack the Makefile, but this gets overwritten on ./configure.

哪里是正确的地方加入(或改变),这是由code要求(相对于该用户可能要更改这些CFLAGS)CFLAGS?

Where is the correct place to add (or change) CFLAGs which are required by the code (as opposed to those CFLAGs which the user might want to change)?

P.S。我想通过编辑一个文本文件(如 Makefile.am configure.ac )要做到这一点,而不是点击Eclipse的一个盒子,如果可能的话。

P.S. I'd like to do this by editing a text file (such as Makefile.am or configure.ac), rather than clicking a box in Eclipse, if possible.

推荐答案

正好碰上同样的问题。

下面是解决方案,只是在配置选项末尾添加CFLAGS:

Here is the solution, just add the CFLAGS at the end of the configure options:

如果您希望编辑要做到这一点 configure.ac ,只需添加 CFLAGS + =东西 configure.ac

If you want to do this by editing configure.ac, just add CFLAGS+=" something" into configure.ac
