使dep：無法完成'depend'

Question

我一直在試圖爲需要SIP的iOS項目編譯PJSIP庫。遵循this教程，我已經能夠運行configure-iphone腳本。下一步將爲依賴項運行make dep，但遺憾的是，它會導致一些我不知道的錯誤。我也嘗試編輯makefile，所以它直接指向文件，但我仍然收到錯誤，所以它可以找到該文件。

/Applications/Xcode.app/Contents/Developer/usr/bin/make -f Samples.mak depend 
make[2]: Nothing to be done for `depend'. 

是我得到的錯誤。

make文件：

include ../../build.mak 
include $(PJDIR)/build/common.mak 

export LIBDIR := ../lib 
export BINDIR := ../bin 

RULES_MAK := $(PJDIR)/build/rules.mak 
SAMPLES_MAK := $(PJDIR)/pjsip-apps/build/Samples.mak

    fi; 

就像我說的，我加了SAMPLES_MAK變量，但遺憾的是它並沒有幫助。我還發現哪條線給了我錯誤，它接近文件末尾$(MAKE) -f $(SAMPLES_MAK) $@。

Answer 1

使用official建築文件。它適用於iOS所有當前體系結構的100％。

Answer 2

通常這表示您意外地（？）在您的工作目錄中創建了一個名爲depend的文件或目錄。因此，make看到該文件或目錄，並且由於makefile沒有列出目標的任何先決條件，它認爲目標是最新的。

這就是爲什麼一般你聲明這些類型的幫助者目標是.PHONY，但顯然makefile不這樣做。
