Problem installing lcm-python and launch lcm-spy under Windows

[Hongkai Dai]

Hi guys,

We tried to install lcm 1.1.0 on a Windows 7 machine with Visual Studio 9. We can build the lcm.sln in WinSpecific folder, and then we can call lcm-gen to generate the lcm types. But we have some problem when we want to install lcm-python. What we did is

1. In lcm-python folder, we call
   python setup.py install
   And the error message is 'cannot open source file : '..\lcm\ lcm_udp.c': No such file or directory'.
2. We can find ..\lcm\lcm_udpm.c, so we replaced line 12 in setup.py to use lcm_udpm.c, but then we get another error:
   'cannot open source file : '..\WinSpecific\WinPorting.cpp': No such file or directory'.
3. We can find the file in ..\lcm\windows\WinPorting.cpp. So we replaced line 54 of setup.py with the correct path, but still we get the error
   'lcm_udpm.obj : error LNK2019: unresolved external symbol XXXXXX'
   the symbols include '_lcm_buf_queue_is_empty', 'void__cdecl lcm_memg_provider_init(struct _GPtrArray *)', etc.
   
   
   

Our second problem is to get lcm-spy running. Which file should we compile to launch lcm-spy on Windows?

Thanks a lot for your kind help! We really appreciate it.

Have you tried the latest version of LCM? There have been some bugfixes since 1.1.0 that may be relevant.
