我正在开发一个并行地图/减少项目。我写的第一个<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/horizontalScrollView">
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<TextView
android:layout_width="800dp"
android:layout_height="100dp"
android:text="New Text"
android:id="@+id/textView2"
android:background="#0000ff"
android:gravity="center"/>
<TextView
android:layout_width="500dp"
android:layout_height="100dp"
android:text="New Text"
android:id="@+id/textView4"
android:background="#ff0000"
android:gravity="center"/>
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
是this one。
然后我按照this教程（在我的链接问题中建议），这是新的makefile：
makefile以下是问题：当我执行第一个makefile生成的二进制文件时，会打印以下（正确的）错误消息：
#

# (dependencies are added to end of Makefile)
# 'make' build executable file 'mycc'

这是通过执行新的二进制文件打印的（奇数）错误消息：
ERROR: FARM, try to add zero workers!
成瘾 Eclipse CDT调试器可以正常使用旧的makefile，而使用新的makefile时会打印出这条错误消息：
mapreduce: /home/luca/fastflow/ff/farm.hpp:1753: ff::ff_Farm<IN_t, OUT_t>::ff_Farm(std::vector<std::unique_ptr<ff::ff_node> >&&, ff::ff_node&, bool) [with IN_t = char; OUT_t = char]: Assertion `nw>0' failed.
Aborted (core dumped)
我是否对新的makefile做错了什么？
