在无法在中找出我的应用程序中发生了什么之后,我尝试在我的pc上复制它,使用valgrind来查找内存/多线程问题。我在很多地方看到过这样的情况:
==769== Possible data race during write of size 4 at 0xACD3ADC by thread #13
==769== Locks held: none
==769== at 0x4C36067: memset (in /usr/lib/valgrind/vgpreload_helgrind-amd64-linux.so)

在Ubuntu 14.04中,当我尝试使用curl时,我得到以下消息:
curl www.google.com
curl: /usr/local/lib/libldap_r-2.4.so.2: no version information available (required by /usr/lib/x86_64-linux-gnu/libcurl.so.4)
curl: /usr/local/lib/liblber-2.4.so.2: no version information available (required by /usr/lib/x86_64-linux-gnu/libcur

/libs/curl.so)
,我试过了.

我是Linux的新手,所以这可能是个新手问题.
在Ubuntu18.04LTS的新安装上,我想安装NodeJS。我运行node --version来验证它是否没有安装:
Command 'node' not found, but can be installed with:
sudo apt install nodejs
因此,它没有安装,终端输出建议如何安装它。
其他一些在线消息来源建议使用wget或curl来安装它,如下所示:
# using wget
wget https://nodejs.org/dist/v12.13.1/node-v12.13.1-linux-x6
我刚开始使用CMake。我在Debian主机上为运行嵌入式Linux的设备使用CMake进行交叉编译。下面是我的CMake工具链文件:
