如何在Linux上正确编译Synergy？

Question

我试着遵循文档中详细的说明。但是，每次使用Make时，都会得到以下错误：

CMake Warning at cmake/Version.cmake:27 (message):
  Synergy version wasn't set.  Set to 2.0.0
Call Stack (most recent call first):
  CMakeLists.txt:48 (include)


-- Full Synergy version string is '2.0.0-snapshot.b1-1cf3baed'

我试图通过将这一行添加到Cmakelists.txt中来修复它：

link_libraries(libcurl)

但这只会导致一个不同的错误：

有谁知道如何修复这个错误并编译协同作用呢？

Answer 1

您缺少libcurl库，尝试使用apt-get install libcurl4-gnutls-dev安装它，然后您应该能够编译该项目

/usr/bin/ld: cannot find -llibcurl

CMake在您的系统上找不到库。在Linux下，库通常安装在系统下，而不是像windows那样安装在项目中。
