我想编译亚太投资促进会在我的 ubuntu 13.04 机器上，但我遇到了 pthread lib 问题。这是我得到的错误：

虽然所有需要的库都已安装：
$ dpkg -l | grep apr && dpkg -l | grep libssl

在 Makefile 中：
APR_LIBS = -L/lib/x86_64-linux-gnu/ -lm -lcrypto -lpthread -lssl -lapr-1 -laprutil-1
答案1
好的，我找到了 - Makefile 中有一个错误
APR_ONLY_LIBS没有链接 libthread：
APR_ONLY_LIBS = -lapr-1
因此我将其改为：
APR_ONLY_LIBS = -lapr-1 -lpthread
答案2
如果您是因为 ant 构建问题而来到此处，只需包含 pthread。
<property name="client.lib.path" value="/usr/local/lib"/> #this filepath
<property name="client.lib.list" value="fltk,pthread,stdc++"/> #this line
<libset dir="${client.lib.path}" libs="${client.lib.list}"/> #variable here with file path mentioned above
