在一台新的电脑上，想要测试一下Basler 的TOF相机，安装好TOF的SDK之后（在这台电脑上我还装了pylon5），编译自己的程序发现出现下面的报错：
Failed to load the producer file ProducerTOF.cti: /opt/pylon5/lib64/gentlproducer/gtl/ProducerTOF.cti: cannot open shared object file: No such file or directory
BaslerToF的包含目录和库目录设置都没问题，这个错是加载这个.cti文件路径不对导致的。
我看了一下SDK里加载这个文件的代码位置（/opt/BaslerToF/include/ConsumerImplHelper/ProducerProxy.h 244行）：
template <const char* ProducerName>void CProducerProxy<ProducerName>::Init(const char* dllname){bool loaded = false;std::string strDllName(dllname);const bool isGenICamTLPathSet = ! GetGenicamGenTLPath().empty();const bool nameContainsSeparator = strDllName.find('/') != std::string::npos || strDllName.find('\\') != std::string::npos;// If there is a path separator in dllname we are going to ignore the GENICAM_GENTL_PATH. We directly try to load the module.// Also directly load the module if there is no GENICAM_GENTL_PATH is set.if ( nameContainsSeparator || ! isGenICamTLPathSet ){
#ifdef CIH_WIN_BUILDif ( ! nameContainsSeparator ){// Assume that the producer is located in the directory indicated by the BASLER_TOF_BIN/BASLER_TOF_BIN64 environment variable
#pragma warning(push, 1)
#pragma warning(disable: 4996)
# if CIH_WORDSIZE == 64const char* szBaslerTofBinDir = getenv("BASLER_TOF_BIN64");
#elseconst char* szBaslerTofBinDir = getenv("BASLER_TOF_BIN");
#endif# if CIH_WORDSIZE == 64
#endif // endif#pragma warning(pop)if ( NULL != szBaslerTofBinDir ){std::string strBinDir( szBaslerTofBinDir );if ( *strBinDir.rbegin() != '\\' && *strBinDir.rbegin() != '/' ){strBinDir += "\\";}
# if CIH_WORDSIZE == 64strBinDir += "x64\\";
# elsestrBinDir += "win32\\";
# endifstrDllName = strBinDir + strDllName;}}
#endifm_pProducerLib = new Internal::CDynamicLib();loaded = m_pProducerLib->Load( strDllName.c_str() );}else{// Iterate over all entries in GENICAM_GENTL_PATH and try to load the desired module from there
#if defined CIH_WIN_BUILDconst char* delimiter = ";";
#elseconst char* delimiter = ":";
#endifstd::list<std::string> lstPathEntries = Tokenize( GetGenicamGenTLPath(), delimiter );for (std::list<std::string>::const_iterator it = lstPathEntries.begin(); it != lstPathEntries.end() && ! loaded; ++it ){std::string strFullPath = *it;if ( *strFullPath.rbegin() != '\\' && *strFullPath.rbegin() != '/' )strFullPath += CIH_PATH_SEPARATOR;strFullPath += strDllName;m_pProducerLib = new Internal::CDynamicLib();loaded = m_pProducerLib->Load( strFullPath.c_str() );}}if (!loaded){std::ostringstream s;throw RUNTIME_EXCEPTION( static_cast<std::ostringstream&>(s << "Failed to load the producer file " << dllname << ": " << m_pProducerLib->GetLastErrorMsg() ).str());}
应该是：GetGenicamGenTLPath()将gentl位置定位到pylon5文件下了。
解决方案：设置正确的GENICAM_GENTL_PATH （/opt/BaslerToF/lib64/gentlproducer/gtl）
或者向我一样偷懒（不推荐），修改代码：
strFullPath = "/opt/BaslerToF/lib64/gentlproducer/gtl/";strFullPath += strDllName;m_pProducerLib = new Internal::CDynamicLib();loaded = m_pProducerLib->Load( strFullPath.c_str() );
