我正在尝试构建pjsip项目。。这是我的pjsip项目制作文件。

 include ../../../build.mak
    include ../../../build/common.mak

    export LIBDIR := ../../lib

    RULES_MAK := $(PJDIR)/build/rules.mak

    #export MYCOMPRESS_LIB := ../../lib/lmycompresslib-$(TARGET_NAME)$(LIBEXT)
    export MYCOMPRESS_LIB := lmycompresslib-$(TARGET_NAME)$(LIBEXT)

    ifeq ($(PJ_SHARED_LIBRARIES),)
    else
    export MYCOMPRESS_SONAME := lmycompresslib.$(SHLIB_SUFFIX)
    export MYCOMPRESS_SHLIB := $(MYCOMPRESS_SONAME).$(PJ_VERSION_MAJOR)
    endif

    depend:
        $(MAKE) -f $(RULES_MAK) APP=MYCOMPRESS app=lmycompresslib $@

这是我得到的错误。

。depend:1:***缺少分隔符。停下来。

我使用此命令验证makefile中是否只有选项卡

CAT-E-T-V生成文件

但是，当我试图构建这个项目时，仍然会出现上述错误。
