Re: Error on building Haskell plugin

Hello, I would like to build and use the Haskell plugin available at http://www.hoovy.org/HaskellXcodePlugin/ but when I build it on Xode 2.5, the following error obtains:

From Xcode/About:

Component versions
Xcode IDE: 799.0
Xcode Core: 798.0
ToolSupport: 794.0


Regretably I don't know much about Xcode but under Frameworks & Libraries / Linked Frameworks there is DevToolsCode.framework. If I click on that, the right pane of the HaskellPlugin window shows DevToolsCore.framework in the `File Name' column.  If I right-click on that and choose Info, the Framework "DevToolsCore.framework" Info window shows

Name: DevToolsCore.framework
Path:   /Developer/Library/PrivateFrameworks/DevToolsCore.framework
Full Path: /Developer/Library/PrivateFrameworks/DevToolsCore.framework

and /Developer/Library/PrivateFrameworks/DevToolsCore.framework does exist.

So why does ld say that it can't find the framework ?


Because we moved the location of our private frameworks in Xcode 2.5 and 3.0 and the Haskell plugin project hasn't yet been updated to conform to that change.

One should expect that when one links to the private frameworks of somebody else's code that changes in that code may break one's project.  When we have a public API for building Xcode plugins, the frameworks that support it will be in /Developer/Library/Frameworks, not /Developer/Library/PrivateFrameworks.
