我试图在Ubuntu上安装Z线程，但遇到了一个问题。 我已经安装了几十次Z线程，但这是第一次发生这种情况。 我通常使用这些来安装它：
wget http://voxel.dl.sourceforge.net/sourceforge/zthread/ZThread-2.3.2.tar.gz tar -xzf ZThread-2.3.2.tar.gz cd ZThread-2.3.2 ./configure CXXFLAGS="-fpermissive" --prefix=/usr/ make && make install 它在上面的configuration命令上出现错误：

在运行libtoolize --copy --force ：
root@Rx:~/ZThread-2.3.2# libtoolize --copy --force libtoolize: putting auxiliary files in `.'. libtoolize: copying file `./ltmain.sh' libtoolize: You should add the contents of the following files to `aclocal.m4': libtoolize: `/usr/share/aclocal/libtool.m4' libtoolize: `/usr/share/aclocal/ltoptions.m4' libtoolize: `/usr/share/aclocal/ltversion.m4' libtoolize: `/usr/share/aclocal/ltsugar.m4' libtoolize: `/usr/share/aclocal/lt~obsolete.m4' libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. root@Rx:~/ZThread-2.3.2#
这是甚么build议我呢？ 这也许是一个更大的问题的一部分？
我刚刚在Ubuntu上安装了ZThread，并发布了如何在https://stackoverflow.com/a/33060825/4455221上解决此问题。 答案的内容按要求复制如下：
ltmain.sh具有空白版本的原因是由于./configure文件中的语法错误。 *** Gentoo sanity check failed! ***之前，您应该有以下错误*** Gentoo sanity check failed! *** *** Gentoo sanity check failed! *** ：
checking for correct ltmain.sh version... grep: character class syntax is [[:space:]], not [:space:] no
该错误位于./configure文件的以下行中：
gentoo_ltmain_version=`grep '^[:space:]*VERSION=' $ltmain | sed -e 's|^[:space:]*VERSION=||'`
将[:space:]更改为[[:space:]] ，它变成以下内容并应解决问题：
gentoo_ltmain_version=`grep '^[[:space:]]*VERSION=' $ltmain | sed -e 's|^[:space:]*VERSION=||'`
在这之后，您可能会遇到编译错误，因为ZThread使用了不赞成使用的语法，您可以通过将以下行添加到./configure来解决此问题。
CXXFLAGS="$CXXFLAGS -fpermissive"
如果这确实和Ubuntu安装，你只是作为根login乐趣..（提示，你应该总是使用sudo）。
为什么不只是做sudo apt-get install libzthread-2.3-2 libzthread-dev ，让包pipe理子系统为你做出聪明的事情。
