What leads to a no suitable image found error on Mac OS X?
提问by Mike Caron
I followed Chris Hanson's adviceabout debugging framework unit tests in Xcode 3.1, but when trying to run the custom executable, the program crashes, stating the below error message [substituted $(BUILD_PRODUCTS_DIR) for the real location of the build products].
我遵循了 Chris Hanson关于在 Xcode 3.1 中调试框架单元测试的建议，但是当尝试运行自定义可执行文件时，程序崩溃，并指出以下错误消息 [用 $(BUILD_PRODUCTS_DIR) 替换构建产品的真实位置]。
2009-03-02 19:56:03.414 otest[28059:10b] Error loading
$(BUILD_PRODUCTS_DIR)/Debug/Unit Tests.octest/
Contents/MacOS/Unit Tests: dlopen($(BUILD_PRODUCTS_DIR_)/Unit
Tests.octest/Contents/MacOS/Unit Tests, 265):
no suitable image found. Did find:
$(BUILD_PRODUCTS_DIR)/Unit Tests.octest/Contents/MacOS/Unit Tests:
mach-o, but wrong architecture
2009-03-02 19:56:03.561 otest[28059:10b] The test bundle at
$(BUILD_PRODUCTS_DIR)/Unit Tests.octest could not be loaded because
it is built for a different architecture than the currently-running
test rig (which is running as unknown).
2009-03-02 19:56:03.568 otest[28060:203] *** NSTask: Task create for path
'$(BUILD_PRODUCTS_DIR)/Unit Tests.octest/Contents/MacOS/Unit Tests'
failed: 8, "Exec format error". Terminating temporary process.
My question is, what leads to the no suitable image found. Did find: ...error message and how can I get the otestexecutable to run correctly so that I can debug my framework unit tests?
我的问题是，是什么导致找不到合适的图像。是否发现：...错误消息以及如何让otest可执行文件正确运行，以便调试我的框架单元测试？
Is there an easier way to do this with out using otest?
有没有更简单的方法来做到这一点而不使用 otest？

otest is running just fine. The error is telling you that it can't load the test bundle, and that the reason why it can't load the test bundle is because it doesn't know what architecture it's running as.
otest 运行良好。该错误告诉您它无法加载测试包，并且它无法加载测试包的原因是因为它不知道它正在运行的架构。
The solution is to set ARCHPREFERENCEin otest's environment. You can do this in Xcode's custom executable editor. Set it to the architecture you want to run tests under.
解决办法是ARCHPREFERENCE在otest的环境中设置。您可以在 Xcode 的自定义可执行编辑器中执行此操作。将其设置为您要在其下运行测试的架构。

The line Unit Tests.octest could not be loaded because it is built for a different architecture than the currently-running test rigwould suggest that the dependencies were built for a different system - perhaps it's a PPC / Intel mismatch or the like?
该行Unit Tests.octest could not be loaded because it is built for a different architecture than the currently-running test rig表明依赖项是为不同的系统构建的 - 也许是 PPC / Intel 不匹配等？
