RE: [cdt-dev] Spawner command line lenght limitations?
|
I am wondering if we are overusing the Spawner framework. My understanding
is that it was really only meant for debug that had specific requirements on
process management.
I have removed its use for invoking the ctags indexer and now use
java.lang.Process directly. No problems so far...

Hi Michail,
It was done for Win98 compatibility reasons. It can be changed easily (
MAX_CMD_SIZE preprocessor macro), we do not support Win98 any more. On
the other hand, there is still command line limitation in WinXP (32K I
suppose). To ignore this problem in QNX IDE we just pass all parameters
to GNU make using temporarily created file.
