Hello, I'm working with Player 3.0.1. I'm developing my own driver. I my driver is based on exampleDriver. I write some messages in main() and I've seen that it doesn't run it. What do I have to do? Thanks -- View this message in context: http://old.nabble.com/Problem-with-main-in-my-new-driver-tp29047344p29047344.html Sent from the playerstage-developers mailing list archive at Nabble.com. |

Is it possible for cmake to check if some C++ stream modifier is defined? I doubt CHECK_SYMBOL_EXISTS is capable to do that. I'd like to modify CMakeLists.txt for epuck driver so it could check if std::showbase is defined in <iostream> (which is not in older g++). Paul |

You can supply CMake with a short program and instruct it to see if it compiles, then based on the result decide if the feature that program uses is supported or not.

There's an example of this in the check for TIMESPEC in cmake/internal/SearchForStuff.cmake. It's also how CMake does things like CHECK_INCLUDE_FILES internally. http://www.cmake.org/Wiki/CMake:How_To_Write_Platform_Checks might help, CHECK_C_SOURCE_COMPILES is at the bottom.

Looking through SearchForStuff.cmake I've found one more thing:
CHECK_LIBRARY_EXISTS (rt clock_gettime "${PLAYER_EXTRA_LIB_DIRS}"
HAVE_LIBRT)
SET (CMAKE_REQUIRED_LIBRARIES rt)
CHECK_FUNCTION_EXISTS (clock_gettime HAVE_CLOCK_GETTIME_FUNC)
SET (CMAKE_REQUIRED_LIBRARIES)
IF (HAVE_LIBRT AND HAVE_CLOCK_GETTIME_FUNC)
SET (HAVE_CLOCK_GETTIME TRUE)
ENDIF (HAVE_LIBRT AND HAVE_CLOCK_GETTIME_FUNC)
On QNX clock_gettime is a part of libc. Due to last if, HAVE_CLOCK_GETTIME
is set wrong way on QNX and replacement is (successfully at least!) used.
I'll try to prepare patch that correct it soon.

Oh My God! Fixing this solved biggest mystery I had with Player on QNX!
Patch will be released as soon as I complete regression tests on other QNX
and Linux machines (I don't want to break anything).
