Eclipse Helios - “无法运行程序make; 不明原因“

Question

I upgraded Eclipse from Galileo to Helios, and when I try doing "Clean Project", I get an error saying "cannot run program make; unknown reason". I was able to run make in Galileo, so I'm not sure why this is happening, and whether anyone else encountered this.

Answer 1

Add PATH to the environment (Preferences -> C/C++ -> Build -> Environment).

I also had to add $ORACLE_HOME to the environment as well (my code uses Pro*C) - looks like CDT isn't picking-up the user's environment variables when it was before.

It's annoying, I know...

Answer 2

An alternative answer that builds on trojanfoe's above.

Assuming you can run make in your native environment shell, the solution depends on whether you selected "Replace native environment with specified one" (OP1) or "Append variables to native environment" (OP2) in (Preferences -> C/C++ -> Build -> Environment):

Solution-OP1: Add PATH to the environment (Preferences -> C/C++ -> Build -> Environment).

I also had to add $ORACLE_HOME to the environment as well (my code uses Pro*C) - looks like CDT isn't picking-up the user's environment variables when it was before.

It's annoying, I know...

Solution-OP2: make sure the location of your make command in the PATH variable in your native environment.

Answer 3

我发现在项目 - >属性 - > C / C ++构建 - >环境中，必须选择“将变量附加到本机环境”而不是“用指定的替换本机环境”。

Answer 4

Some amplification on this helpful information for OS X that I discovered this evening with Helios:

my make was located in /Developer/usr/bin; I added this to the PATH variable.

In the C/C++ Build -- Settings section of the project preferences, I added the /Developer/SDKs/MacOSX10.6.skd/usr/lib directory. It includes the libraries you will need.
